Oral Nitrate Administration Ameliorates Cardiogenic Shock due to Eclipsed Mitral Regurgitation

Thu, 17 Mar 2016 04:34:27 +0100

Eclipsed mitral regurgitation (MR) has been reported as transient massive functional MR caused by a sudden coaptation defect in the absence of left ventricular remodeling or epicardial coronary artery stenosis. Coronary spasm or microvascular dysfunction has been suggested to be associated with the pathogenesis. Here, we present a 68-year-old woman with eclipsed MR with cardiogenic shock ameliorated by nitrate. She was admitted for transient shock with massive functional MR. Transient MR was associated with a complete absence of mitral leaflet coaptation owing to tethering of the lateral posterior mitral leaflet. The leaflet tethering was triggered by transient myocardial ischemia around the anterolateral papillary muscle, which could have been caused by coronary spasm and/or microvascular...

Hemiarch replacement with concomitant antegrade stent grafting of the descending thoracic aorta versus total arch replacement for treatment of acute DeBakey I aortic dissection with arch tear [AORTIC SURGERY]

Wed, 16 Mar 2016 00:00:00 +0100

CONCLUSION In treating DeBakey I aortic dissection with arch tear, hemiarch replacement with primary tear repair and concomitant TEVAR is a safe alternative to conventional TAR, with improved distal aortic remodelling. (Source: European Journal of Cardio-Thoracic Surgery)

Contemporary management of acute right ventricular failure: a statement from the Heart Failure Association and the Working Group on Pulmonary Circulation and Right Ventricular Function of the European Society of Cardiology

Tue, 15 Mar 2016 00:00:00 +0100

Acute right ventricular (RV) failure is a complex clinical syndrome that results from many causes. Research efforts have disproportionately focused on the failing left ventricle, but recently the need has been recognized to achieve a more comprehensive understanding of RV anatomy, physiology, and pathophysiology, and of management approaches. Right ventricular mechanics and function are altered in the setting of either pressure overload or volume overload. Failure may also result from a primary reduction of myocardial contractility owing to ischaemia, cardiomyopathy, or arrhythmia. Dysfunction leads to impaired RV filling and increased right atrial pressures. As dysfunction progresses to overt RV failure, the RV chamber becomes more spherical and tricuspid regurgitation is aggravated, a ca...

Decade-Long Trends (2001-2011) in the Incidence and Hospital Death Rates Associated with the In-Hospital Development of Cardiogenic Shock after Acute Myocardial Infarction [Original Articles]

Tue, 15 Mar 2016 00:00:00 +0100

Conclusions— We found suggestions of a decline in the death, but not incidence, rates of cardiogenic shock over time. These encouraging trends in hospital survival are likely because of advances in the early recognition and aggressive management of patients who develop cardiogenic shock.

Multidisciplinary approach for primary cardiac lymphoma associated with hemodynamic failure caused by tricuspid valve obstruction

Mon, 14 Mar 2016 00:00:00 +0100

We report the case of a 65-year-old man with PCL associated with unstable hemodynamics caused by tricuspid valve obstruction. Generally, chemotherapy is the first choice of treatment for patients with PCL. This patient required emergency tumor reduction as he was at risk of having acute hemodynamic failure caused by tricuspid valve obstruction. Therefore, he underwent a 2-staged treatment: urgent surgery to avoid sudden death by tricuspid valve obstruction as well as pulmonary embolism during chemotherapy, followed by early chemotherapy. Pathological findings showed diffuse large B-cell lymphoma, and rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, prednisolone (R-CHOP) therapy was initiated to treat any residual tumor infiltrating the myocardial wall. The patient showe...

Sequential Organ Failure Assessment Score at Presentation Predicts Survival in Patients Treated With Percutaneous Veno-Arterial Extracorporeal Membrane Oxygenation.

Fri, 11 Mar 2016 00:32:02 +0100

CONCLUSIONS: Lower presenting SOFA score and smaller cannula size were associated with increased survival in patients with cardiogenic shock (CS) or CA who underwent percutaneous VA-ECMO placed in the cardiac catheterization laboratory using a portable system. Calculation of the SOFA score at presentation may help physicians determine which patients may derive benefit from ECMO. Smaller cannula size, while decreasing the amount of flow, may result in decreased bleeding and increased survival.

Bail-Out Use of Impella CP as a Bridge to TAVI in a Cardiogenic Shock Patient: The "Pump-Rewiring" Technique.

Fri, 11 Mar 2016 00:32:02 +0100

CONCLUSION: This case example demonstrates how a tailored step-by-step strategy including PCI, BAV, peripheral angioplasty, percutaneous ventricular assistance, and transcatheter aortic valve implantation (TAVI) allowed the successful treatment of a critical patient with CS. Impella CP could be considered an effective bridge to TAVI in patients developing aortic regurgitation after BAV, since maintaining arterial access can be achieved using the pump-rewiring technique.

Contemporary Use of Veno-Arterial Extracorporeal Membrane Oxygenation for Refractory Cardiogenic Shock in Acute Coronary Syndrome.

Fri, 11 Mar 2016 00:32:02 +0100

CONCLUSION: VA-ECMO is infrequently used in patients for cardiopulmonary resuscitation in the AMI setting. When used judiciously, it has good clinical outcomes in this group of patients. However, use of VA-ECMO should be individualized based on vascular anatomy for best results. Close cooperation among interventional cardiologists, cardiovascular surgeons, cardiologists, cardiac intensivists, and perfusionists is essential for success of this therapy for RCS in AMI.

The Use of Mechanical Support Devices in Percutaneous Coronary Interventions: The Controversy?

Wed, 09 Mar 2016 00:00:00 +0100

We read with great interest the report by Khera et al describing the use of mechanical support (MCS) devices in percutaneous coronary interventions (PCI) using the Nationwide Inpatient Sample (NIS) data.1 The authors did not find any evidence of clear benefit with the use of percutaneous ventricular assist devices (PVADs), i.e. Impella and TandemHeart, when compared with intraaortic balloon pump (IABP) in patients undergoing PCI in the propensity matched population or in the subgroups of patients with cardiogenic shock, acute myocardial infarction (AMI) without cardiogenic shock and non- AMI/non cardiogenic shock (elective high-risk PCI).

Mechanical Circulatory Support in Pediatrics.

Tue, 08 Mar 2016 21:17:01 +0100

Authors: Steffen RJ, Miletic KG, Schraufnagel DP, Vargo PR, Fukamachi K, Stewart RD, Moazami N Abstract End-stage heart failure affects thousands of children yearly and mechanical circulatory support is used at many points in their care. Extracorporeal membrane oxygenation supports both the failing heart and lungs, which has led to its use as an adjunct to cardiopulmonary resuscitation as well as in post-operative cardiogenic shock. Continuous-flow ventricular assist devices (VAD) have replaced pulsatile-flow devices in adults and early studies have shown promising results in children. The Berlin paracorporeal pulsatile VAD recently gained U.S. Food and Drug Administration approval and remains the only VAD approved in pediatrics. Failing univentricular hearts and other congenitally...

Complete versus culprit-only revascularization in ST-elevation myocardial infarction and multivessel disease

Mon, 07 Mar 2016 00:00:00 +0100

In conclusion, the current available evidence from the randomized clinical trials, with a total sample size of only 2000 patients, is not robust enough to firmly recommend complete revascularization in STEMI patients. This uncertainty lends support to the continuation of the COMPLETE trial. This ongoing trial is anticipated to enroll 3900 patients with STEMI from across the world, and will be powered for the hard outcomes of death and myocardial infarction. Until the results of the COMPLETE trial are reported, physicians need to individualize care regarding the opportunity and the timing of the non-IRA PCI. (Source: Internal and Emergency Medicine)

Radial vs. femoral approach in STEMI: what do we know so far?

Sun, 06 Mar 2016 14:13:01 +0100

Authors: Santucci A, Gargiulo G, Ariotti S, Marino M, Magnani G, Baldo A, Piccolo R, Franzone A, Valgimigli M Abstract Radial approach has been used since 1989 to perform coronary angiography as an alternative to femoral access. During past decades, the development of dedicated equipment led to high efficacy also in complex procedures. ST elevation myocardial infarction (STEMI) is known to be a high bleeding risk setting and in turn bleeding events can negatively impact on outcomes. Observational studies have demonstrated feasibility, efficacy and safety of radial approach when compared to femoral access in STEMI patients, with benefit in bleeding rates. These advantages have been described also in specific populations as elderly or patients in cardiogenic shock. Some large randomi...

Initial Experience of Transaortic Catheter Venting in Patients with Venoarterial Extracorporeal Membrane Oxygenation for Cardiogenic Shock

Tue, 01 Mar 2016 06:00:00 +0100

Extracorporeal membrane oxygenation (ECMO) has become one of the often applied mechanical support for acute cardiogenic shock. During venoarterial (VA) ECMO support, left heart decompression should be considered when left ventricular (LV) distension develops with pulmonary edema and LV dysfunction. The aim of this study was to report the results of transaortic catheter venting (TACV), as an alternative venting method, performed during VA-ECMO in patients with acute cardiogenic shock. We retrospectively reviewed the records of seven patients who underwent both ECMO and TACV between February 2013 and February 2014. Extracorporeal membrane oxygenation was performed uneventfully, and TACV was introduced under transthoracic echocardiographic guidance in all cases. Hemodynamic parameters, LV eje...

Abstract 268: Using Lean Methodology to Reduce Variation in Care of Acute Coronary Syndrome Patients [Session Title: Abstract Poster Session II]

Fri, 26 Feb 2016 00:00:00 +0100

Discussion: BC is attempting to reduce unexplained variation in coronary revascularization using the Lean methodology to take a systematic approach to the analysis of the process of ACS care across the province. Involving physicians and point of care staff in the detailed mapping process has proven to be a significant step in engaging key stakeholders in the project by allowing input into the process of describing the factors affecting variation of practice at each site. The next step is to convene provincially to determine where to improve standardized practice in order to improve patient outcomes at key points along the value stream.

An unusual case of cardiogenic shock late following surgical aortic valve replacement

Thu, 25 Feb 2016 00:00:00 +0100

Publication date: Available online 24 February 2016 Source:Journal of Cardiology Cases Author(s): Maria Chiara Todaro, Alfonso Ielasi, Antonio Silvestro, Davide Personeni, Giulietta Grigis, Antonio Saino, Maurizio Tespili The present case describes a rare but potentially life-threatening complication following surgical aortic valve replacement (AVR): iatrogenic coronary ostial stenosis (ICOS). The incidence of ICOS is estimated to be between 0.3% and 5% of all AVR and it generally occurs within 6 months after the procedure. In most cases, either the left main stem or the ostium of the right coronary artery (RCA) is affected, although stenosis of the ostium of the left anterior descending artery can also occur. However, to the best of our knowledge, the simultaneous involvement of ...

Spontaneous coronary artery dissection resulting in very late stent thrombosis

Wed, 24 Feb 2016 00:00:00 +0100

A 58-year-old man with a history of coronary angioplasty done to right coronary artery 6 years back presented to the hospital with sudden-onset chest pain for 1 h. His ECG on admission revealed ST elevation in leads II, III and augmented vector foot (aVF). The patient was thrombolysed with streptokinase, which resulted in resolution of chest pain and ECG changes. Three hours later there was reappearance of ST elevation in same leads with cardiogenic shock. It was decided to take the patient for rescue angioplasty. Angiogram revealed significant luminal stenosis of proximal right coronary artery along with in-stent thrombotic occlusion (see online supplementary video 1). The optical coherence tomography (OCT) study showed evidence of coronary dissection with intramural haematoma p...

Severe Acute Traumatic Mitral Regurgitation, Cardiogenic Shock Secondary to Embolized Polymethylmethracrylate Cement Foreign Body After a Percutaneous Vertebroplasty.

Mon, 22 Feb 2016 18:25:05 +0100

We report the case of a 61-year-old woman with acute decompensated heart failure secondary to acute traumatic mitral regurgitation, resulting from polymethylmethacrylate cement found in the left ventricle less than 24 hours after fluoroscopic percutaneous vertebroplasty. The patient had a history of ovarian cancer and had undergone treatment for symptomatic osteoporotic compression fractures of the vertebrae (T11, L1, and L3). The patient underwent a successful emergency open-heart operation, mitral valve replacement, closure of an atrial septal defect, and video-assisted removal of the cement foreign body from the left ventricle. The patient was later discharged with a good outcome. PMID: 26897199 [PubMed - as supplied by publisher] (Source: The Annals of Thoracic Surgery)

Primary Angioplasty For Patients in Cardiogenic Shock – Optimal Management

Wed, 17 Feb 2016 06:06:14 +0100

Cardiogenic shock is a clinical condition of inadequate end-organ perfusion due to cardiac dysfunction (see Table 1). It most commonly occurs in the setting of acute MI with left ventricular failure (~80 % cases),1,2 but can also be caused by right ventricular infarction or late mechanical complications, such as acute mitral regurgitation or ventricular rupture (septal or free wall). Non-infarct-related cardiogenic shock is comparatively rare, and may result from decompensated valvular heart disease and arrhythmias, to name a few mechanisms. (Source: Radcliffe Cardiology)

Cardiogenic Shock How Long Does the Storm Last? ∗

Tue, 16 Feb 2016 04:19:11 +0100

Cardiogenic shock, the most common cause of in-hospital mortality following acute myocardial infarction (AMI), complicates between 5% and 10% of cases (1). Although the past few decades have seen a decline in early mortality in patients with cardiogenic shock—largely due to increased rates of early revascularization (2) and improved adjunctive pharmacotherapy—in-hospital mortality remains high, at up to 50% (3). Although cardiogenic shock is more common among patients with ST-segment elevation myocardial infarction (STEMI), patients with non–ST-segment elevation myocardial infarction (NSTEMI) tend to have higher baseline risk profiles. Some registries report no difference in early mortality according to AMI subtype in patients with cardiogenic shock (4). Others report higher mortal...

Effective percutaneous “edge‐to‐edge” mitral valve repair with mitraclip in a patient with acute post‐MI regurgitation not related to papillary muscle rupture

Tue, 16 Feb 2016 00:00:00 +0100

A 65‐year‐old woman was admitted to our institution for rest dyspnea and hypotension. EKG showed sinus tachycardia with signs of infero‐posterior STEMI. 2D‐echocardiogram showed severe left ventricular systolic dysfunction with a‐ diskynesia of the inferior and posterior walls and severe functional mitral regurgitation (MR). The patient underwent urgent coronary angiography that showed 3‐vessels disease with total occlusion of both first obtuse marginal (OM) branch of the left circumflex artery and right coronary artery (RCA) and critical stenosis of left anterior descending (LAD).

Long-term intravenous inotropes in low-output terminal heart failure?

Mon, 15 Feb 2016 00:00:00 +0100

Abstract Intravenous inotropic therapy may be necessary to achieve short-term survival in end-stage heart failure patients with cardiogenic shock or extreme low output and severe organ hypoperfusion. However, mid- or long-term intravenous inotropic therapy is associated with an increased mortality in advanced stage D heart failure patients using β-adrenoceptor agonists (dobutamine) or PDE-3-inhibitors (milrinone). Intermittent levosimendan may evolve as a reasonable therapeutic option. Randomized trials or other meaningful scientific evidence addressing the optimal treatment of exclusively the most threatened subgroup of hospitalized patients with persistent severe organ hypoperfusion are missing, but urgently needed. Despite a lack of other beneficial pharmacological options, th...

Understanding cardiogenic shock: a nursing approach to improve outcomes.

Sun, 14 Feb 2016 19:12:02 +0100

Authors: Warise L Abstract Shock is a common complication associated with cardiac hospitalization post-myocardial infarction. Although shock is considered a physiologic response rather than a disease state, the lack of adequate pumping function leads to decreased tissue perfusion and initiation of the general shock response. Regardless of the etiology, the effects of shock are the same. Shock is essentially a widespread impairment of cellular metabolism, specifically, resulting from anaerobic metabolism related to inadequate tissue oxygenation leading to tissue dysfunction and necrosis. The purpose of this article is based on an actual clinical case study, precipitating factors, pathophysiology, common medical diagnosis and therapy, and nursing implications. PMID: 25650490 [Pu...

This article focuses on specialized techniques and devices used in the most challenging cases of acute myocardial infarction. Areas where high-quality evidence is either clear or absent are avoided. Controversies in the use of support or thrombectomy devices, the addition of adjunct pharmacology, and the decision to treat nonculprit lesions are discussed. Recent years have seen a shift in guidelines to downgrading the use of assist devices in cardiogenic shock and aspiration thrombectomy, whereas consideration of nonculprit coronary intervention has been revived. These changes come in the wake of a series of large, practice-changing clinical trials. (Source: Interventional Cardiology Clinics)

Patients With Acute Myocardial Infarction–Related Cardiogenic Shock

Wed, 10 Feb 2016 00:00:00 +0100

To the Editor We read with great interest the Viewpoint by Tchantchaleishvili et al calling for organized statewide networks for the management of acute myocardial infarction–related cardiogenic shock. We applaud the authors’ insights into one of the major current challenges in cardiovascular care. Despite advances in the treatment of coronary artery disease and in the technology of mechanical circulatory support devices (MCSDs), patients with myocardial infarction complicated by cardiogenic shock still have mortality rates in the range of 40% to 50%. While no trial since the SHOCK (Should We Emergently Revascularize Occluded Coronaries for Cardiogenic Shock) trial has demonstrated a clear benefit to any intervention beyond early revascularization, observational data suggest that impro...

Incessant fascicular VT presenting as cardiogenic shock with multi-organ dysfunction syndrome

Mon, 08 Feb 2016 00:00:00 +0100

We report a rare clinical presentation of incessant idiopathic fascicular ventricular tachycardia (FVT), presenting as multi-organ dysfunction (MOD) syndrome with cardiogenic shock. Our patient was a 19-year-old male who presented with slowly progressive dyspnea from New York Heart Association (NYHA) II to NYHA IV at the time of presentation, palpitations, and dilated cardiomyopathy due to drug-refractory FVT. The patient was in cardiogenic shock with raised central venous pressures and required inotropic support for maintaining systolic blood pressure above 90mmHg. The MOD was seen in the form of deranged liver and kidney parameters. Echocardiography showed a dilated left ventricle (LV, 58mm at end-diastole, 52mm at end-systole) and decreased ejection fraction (20%). Electrocardiography s...

Is Extracorporeal Membrane Oxygenator a New Weapon to Improve Prognosis in Patients With Profound Cardiogenic Shock Undergoing Primary Percutaneous Coronary Intervention?

Mon, 08 Feb 2016 00:00:00 +0100

Authors: Sung PH, Wu CJ, Yip HK Abstract Despite advancements in pharmacological therapy and refinement of the tools and technique of primary percutaneous coronary intervention (PCI) and coronary artery bypass surgery, patients with acute myocardial infarction (AMI) complicated by profound cardiogenic shock (CS) still have unacceptably high in-hospital mortality and unfavorable long-term outcome. Thus, there is an imminent need of a new and safe treatment modality in the management of AMI complicated by profound CS. Growing evidence suggests that extracorporeal membrane oxygenator (ECMO)-supported primary PCI is an effective therapeutic option for saving lives under such conditions. In this review, we describe and interpret the potential role of circulatory mechanical support by EC...

Two Cases of Refractory Cardiogenic Shock Secondary to Bupropion Successfully Treated with Veno-Arterial Extracorporeal Membrane Oxygenation.

Mon, 08 Feb 2016 00:00:00 +0100

We report two cases of severe bupropion toxicity resulting in refractory cardiogenic shock, cardiac arrest, and repeated seizures treated successfully. Patients with cardiovascular failure related to poisoning may particularly benefit from extracorporeal membrane oxygenation (ECMO). These are the first cases of bupropion toxicity treated with veno-arterial EMCO (VA-ECMO) in which bupropion toxicity is supported by confirmatory testing. Both cases demonstrate the effectiveness of VA-ECMO in poisoned patients with severe cardiogenic shock or cardiopulmonary failure.

Shock, acute disseminated intravascular coagulation, and microvascular thrombosis: is ‘shock liver’ the unrecognized provocateur of ischemic limb necrosis?

Sat, 30 Jan 2016 00:00:00 +0100

Summary For unknown reasons, a small minority of critically ill patients with septic or cardiogenic shock, multiorgan failure, and disseminated intravascular coagulation develop symmetrical acral (distal extremity) limb loss due to microvascular thrombosis (‘limb gangrene with pulses’). Case reports have described preceding ‘shock liver’ in some critically ill patients who developed such a picture of ischemic limb necrosis. This suggests that profoundly disturbed procoagulant–anticoagulant balance featuring uncontrolled generation of thrombin—resulting from failure of the protein C and antithrombin natural anticoagulant systems due to insufficient hepatic synthesis of these crucial proteins—could explain the microvascular thrombosis and associated limb loss. We hypothesize th...

In-Hospital Outcome of Patients with Cardiogenic Shock Complicating Acute Myocardial Infarction: Results from Royal Hospital Percutaneous Coronary Intervention Registry, Oman.

Fri, 29 Jan 2016 04:56:04 +0100

CONCLUSIONS: CS in AMI patients presenting to a tertiary hospital in Oman have high in-hospital mortality despite the majority undergoing PCI. Even though the in-hospital mortality is comparable to other studies and registries, there is an urgent need to determine the causes and find any remedies to provide better care for such patients, specifically concentrating on the early transfer of patients from regional hospitals for early PCI.

Acute myocardial infarction due to left main coronary artery disease in men and women: does ST-segment elevation matter?

Fri, 22 Jan 2016 09:39:02 +0100

CONCLUSIONS: There were no gender-related differences in the management within the STEMI or NSTEMI group. Although acute myocardial infarction due to ULMCA disease is associated with high mortality in both genders, STEMI was a negative prognostic factor of in-hospital and 12-month mortality. Despite poor baseline characteristics and clinical presentation in women, female gender itself did not influence mortality. PMID: 26788080 [PubMed] (Source: Archives of Medical Science)

A large pseudoaneurysm of the left ventricle was recognized and successfully treated surgically. PMID: 26336464 [PubMed] (Source: Polish Journal of Cardio-Thoracic Surgery)

Oxygenator in short-term LVAD circuit: a rescue in post-LVAD pulmonary complications.

Wed, 20 Jan 2016 00:00:00 +0100

Authors: Mohite PN, Patil NP, Popov AF, Bahrami T, Simon AR Abstract Pulmonary complications after left ventricular assist device (LVAD) implantation, though infrequent, can be potentially catastrophic. A 62-year-old female with cardiogenic shock, supported on short-term LVAD, developed pulmonary oedema. An oxygenator was introduced into the LVAD circuit, which improved the gas exchange and, eventually, after weaning off the oxygenator, the patient received long-term LVAD. The introduction of an oxygenator into the short-term LAVD circuit is a lifesaving manoeuvre in such a situation. It offers freedom of introducing and removing the oxygenator into the LVAD circuit without opening the chest and competing for LVAD flow.

Management Strategies and Outcomes of ST‐Segment Elevation Myocardial Infarction Patients Transferred After Receiving Fibrinolytic Therapy in the United States

Tue, 19 Jan 2016 00:00:00 +0100

ABSTRACT Fibrinolytic therapy is still used in patients with ST‐segment elevation myocardial infarction (STEMI) when the primary percutaneous coronary intervention cannot be provided in a timely fashion. Management strategies and outcomes in transferred fibrinolytic‐treated STEMI patients have not been well assessed in real‐world settings. Using the Nationwide Inpatient Sample from 2008 to 2012, we identified 18 814 patients with STEMI who received fibrinolytic therapy and were transferred to a different facility within 24 hours. The primary outcome was in‐hospital mortality. Secondary outcomes included gastrointestinal bleeding, bleeding requiring transfusion, intracranial hemorrhage (ICH), length of stay, and cost. The patients were divided into 3 groups: those who received medic...

Postinfarction ventricular septal rupture: can we improve clinical outcome of surgical repair?

Mon, 18 Jan 2016 00:00:00 +0100

Abstract Postinfarction ventricular septal rupture (VSR) is a lethal structural complication following acute myocardial infarction (AMI). Surgical repair of VSR was first reported in 1957 by Cooley. Since then, many methods have been introduced, variously using right and/or left ventriculotomy. Daggett used infarctectomy and septal reconstruction via left ventriculotomy, reporting 52 % operative mortality when repair was attempted within 21 days, but only 7 % when done after 3 weeks. Komeda and David described single pericardial patch infarct exclusion without infarctectomy through a left ventriculotomy in 1990. It seemed conceptually simple, and became a standard technique. Modifications of that technique and development of other methods have been reported by many surgeons. N...

Left ventricular thrombus associated with arteriovenous extra corporeal membrane oxygenation.

Sat, 16 Jan 2016 07:24:04 +0100

Authors: Makdisi G, Hashmi ZA, Wozniak TC, Wang IW Abstract Extra corporeal membrane oxygenation (ECMO) has remarkably progressed over the recent years. It has become an invaluable tool in the care of adults and pediatric patients with severe cardiogenic shock. At the initiation of ECMO support, the left ventricular contractility is profoundly impaired. Inadequate right ventricular drainage and bronchial circulation can lead to left ventricular distension, with potential deleterious consequences, ranging from inadequate myocardial rest, pulmonary edema, or intracardiac clot formation. Therefore, it is of extreme importance to ensure an adequate left ventricular drainage. Here we present a case of LV thrombus developed while the patient is on central venoarterial (VA) ECMO. PMI...

Spinal Cord Infarct During Concomitant Circulatory Support With Intra-Aortic Balloon Pump and Veno-Arterial Extracorporeal Membrane Oxygenation

Sat, 16 Jan 2016 05:45:21 +0100

Conclusions: The timeline of events suggests a causal relation between intra-aortic balloon pump, veno-arterial extracorporeal membrane oxygenation, and significant neurologic deficits. This is likely due to hypoperfusion of the spinal cord, which is multifactorial in origin, including small aortic calibre, low cardiac output states, high vasopressor requirements causing vasospasm of the artery of Adamkiewicz, occlusion of retrograde oxygenated blood flow from peripheral veno-arterial extracorporeal membrane oxygenation due to intra-aortic balloon pump being in situ, and possible thromboembolic phenomena. The thoracic spinal cord is intrinsically susceptible to ischemia due to the anatomy of the arterial supply, which is described here. We identify several risk factors and make several rec...

An unusual case of fulminant myocarditis closely mimicking ST-segment elevation myocardial infarction and presenting as refractory cardiogenic shock complicated by multiple life-threatening arrhythmiasAn unusual case of fulminant myocarditis

Sat, 16 Jan 2016 00:00:00 +0100

We report a case of severe fulminant myocarditis that closely mimicked acute inferior ST-segment elevation myocardial infarction (STEMI) and presented with refractory cardiogenic shock, multiple life-threatening arrhythmias and rapidly progressive liver failure. This case was successfully differentiated from STEMI by emergency coronary angiography. Recurrent cardiogenic shock was reversed by intra-aortic balloon pumping (IABP). Life-threatening arrhythmias including ventricular tachycardia, ventricular fibrillation, and high-degree atrioventricular block (AVB) were terminated by immediate cardioversion and temporary pacemaker. High-dose hydrocortisone effectively attenuated the inflammatory injury to the myocardium. The patient recovered and was well at the follow-up visit four months afte...

Bilateral mini-thoracotomy off-pump Jarvik 2000 implantation in regional asymmetric paravertebral analgesia

Tue, 12 Jan 2016 17:01:45 +0100

We describe the surgical technique and treatment of a 59-year-old male with cardiogenic shock, who underwent a minimally invasive off-pump ventricular assist device (VAD) implantation with the aid of paravertebral regional analgesia in bilateral mini-thoracotomies as first procedure described in the literature. He was extubated soon after the procedure, in the operating room, with the aim to reduce the right ventricle impairment. These issues are particularly true for patients suffering from pulmonary hypertension and disease, in whom the shortest time of postoperative intubation is fundamental to allow self-inotropic support and recovery of the right ventricle. We illustrate how a minimally invasive implant may improve the clinical outcomes of VAD patients shortening their return time to ...

Complete occlusion of the left main trunk coronary artery by a cardiac papillary fibroelastoma in a hemodynamically unstable patient

Tue, 12 Jan 2016 00:00:00 +0100

We present the case of a 60-year-old woman who underwent stent placement in the LMT three years prior to developing chest pain and cold sweats. On coronary arteriography, the catheter could not be advanced into the LMT due to resistance in the ostium. Insertion of the catheter was achieved after the resolution of resistance via catheterization of the LMT by means of an intra-aortic balloon pump drive system. The LMT was normal, and the patient's circulatory failure improved. The cause of the LMT embolism was a cardiac papillary fibroelastoma. Primary surgical excision is the recommended therapy for symptomatic cardiac papillary fibroelastoma. If the patient is hemodynamically stable, it may be possible to delay surgery. However, the patient in question developed cardiogenic shock secondary...

While most cases are asymptomatic or have mild dyspnea, rupture of chordae tendinea or papillary muscles are catastrophic complications that may rapidly lead to cardiogenic shock and death. Despite the presence of pulmonary oedema and/or cardiogrenic shock, the murmur of acute MR is usually subtle due to rapid equalization of left atrial and left ventricular pressure gradient, and therefore misleading. Echocardiography is the definite diagnostic modality...

A 31year old male with no significant past medical history was transferred to our institution for management of cardiogenic shock after presenting with new severe bi-ventricular dysfunction. Previously, he had smoked regular crystal-methamphetamine, with heavy daily usage for 8years until becoming abstinent 2months prior to presentation. He had also used intermittent gamma hydroxyl-butymate with occasional heavy alcohol binges. Throughout this period of substance use, he had maintained regular employment and had a supportive social network. (Source: International Journal of Cardiology)
