OBJECTIVES: Left ventricular assist device implantation is an established therapy for paediatric patients with end-stage heart failure. Early right ventricular dysfunction (RVD) after implantation still remains a challenge in the postoperative period. This study sought to determine the incidence of RVD and to identify echocardiographic predictors of RVD in paediatric patients, as well describing associated clinical outcome. METHODS: Prospectively collected preoperative echocardiographic, haemodynamic, demographic and biochemical data from 48 patients scheduled for left ventricular assist device implantation were evaluated...

INTRODUCTION: Dynamic obstruction of right ventricle outflow tract (RVOTO) is a rare condition that may acutely cause severe heart failure. It has been reported in some hypertrophic cardiomyopathies, after lung transplantation, and in some cases of hemodynamic instability after cardiopulmonary bypass. PRESENTATION OF CASE: We report the case of a 71-year-old man who developed severe hypotension during the induction of general anesthesia for surgical coronary revascularization...

Heart failure experts recommend initiation of continuous inotrope therapy, such as milrinone or dobutamine, for clinically decompensating patients with stage D heart failure. Although originally intended to serve solely as a bridge to more definitive surgical therapies, more and more patients are receiving inotrope therapy for purely palliative purposes. In these cases, questions arise regarding care at the end of life. What criteria determine ongoing clinical benefit? Should the inotrope be continued until death? Should inotrope dosing be increased within recommended guidelines to improve symptoms? What is the role of inotropes in hospice care? Here, we describe such a case as a springboard to contemplate the evolving role of inotrope therapies and how hospice and palliative providers may interface with this rapidly developing face of advanced heart failure care...

Background/Objective: The cardiac Na(+)/Ca(2+) exchanger (NCX) has been identified as a promising target to counter arrhythmia in previous studies investigating the benefit of NCX inhibition. However, the consequences of NCX inhibition have not been investigated in the setting of altered NCX expression and function, which is essential, since major cardiac diseases (heart failure/atrial fibrillation) exhibit NCX upregulation. Thus, we here investigated the effects of the NCX inhibitor SEA0400 on the Ca(2+) transient amplitude and on proarrhythmia in homozygous NCX overexpressor (OE) and heterozygous NCX knockout (hetKO) mice compared to corresponding wild-types (WTOE/WThetKO)...

We present the case of an 88-year-old gentleman who presented to hospital septic with bilateral leg cellulitis, pulmonary oedema and hypotension. He had no history of heart disease but had had bilateral carpal tunnel releases. His condition deteriorated with refractory hypotension in spite of fluid filling, inotropic and vasopressor support. His echocardiogram showed an infiltrative cardiomyopathy with a speckled myocardium, severe concentric left and right ventricular increased wall thickness, diastolic dysfunction, biatrial dilatation and restrictive physiology in keeping with cardiac amyloidosis...

Venom of Leiurus abdullahbayrami (Scorpiones: Buthidae) is an extremely toxic one and it stimulates voltage-gated sodium and potassium channels. In case of a stung by this scorpion; excessive catecholamine release occur and it impairs left ventricle contractility and consequently a heart failure occurs (scorpion sting-related cardiomyopathy). In addition to this cardiac-induced acute pulmonary, edema may occur in severe cases too. An 11-year-old male child who was stung by a scorpion (species: Leiurus abdullahbayrami) consulted to the Emergency Room...

Here we analyzed systemic (plasma) and local (heart/aorta) changes in ACE/ACE-2 balance in Tgαq*44 mice in course of heart failure (HF). Tgαq*44 mice with cardiomyocyte specific Gαq overexpression and late onset of HF were analyzed at different age for angiotensin pattern in plasma, heart and aorta using liquid chromatography/mass spectrometry, for progression of HF by in vivo magnetic resonance imaging under isoflurane anesthesia and for exercise capacity by voluntary wheel running. Six-month-old Tgαq*44 mice displayed decreased ventricle radial strains and impaired left atrial function...

PURPOSE OF REVIEW: Extended survival with LVADs has generated interest in implantation for ambulatory patients with advanced heart failure (HF) prior to dependence on inotropes, though we remain limited in our ability to define and advance indications in this less sick advanced HF population. RECENT FINDINGS: The MedaMACS and ROADMAP studies have informed prognosis and decision-making for ambulatory patients with advanced HF. Sicker INTERMACS profiles are consistently associated with high risk of death or rescue LVAD...

We developed a translation model of alcoholic cardiomyopathy in rats. By the end of forced alcoholization (the rats received 10% ethanol solution as the only source of fluid for 24 weeks; mean daily ethanol consumption was 5.0-6.5 g/kg), the rats developed dilated heart failure. Echocardiography and morphometric study of the myocardium revealed a decrease in inotropic function of the heart and dilatation of the right and left ventricles. Fatty degeneration of the myocardium (pathognomonic sign of alcoholic cardiomyopathy) and decrease in electrical stability of cardiomyocytes reliably reproduce the clinical pattern of alcoholic cardiomyopathy...

This CME article addresses the pathophysiology, incidence, current survival outcome and treatment options for patients with cardiogenic shock as a complication of acute myocardial infarction. The shock spiral of left heart failure due to cardiac infarction, subsequent vasoconstriction and paradoxical vasodilation due to the systemic inflammation response syndrome (SIRS) is a vicious circle which must be interrupted. Treatment focuses on the evidence from randomized clinical trials and the current guideline recommendations...

Iron deficiency (FeD), with or without anemia, in adults with heart failure (HF) is associated with poor outcomes, which can be improved with replacement therapy. A similar therapeutic opportunity may exist for children; however, iron laboratory measurements and FeD have not been described in pediatric patients with HF. A single-center, retrospective study was conducted on 28 patients <21 years old with a diagnosis of dilated cardiomyopathy and HF who had iron laboratories (serum iron, iron saturation, and ferritin) performed...

The risk of cardiac or lung failure after liver transplantation (LT) is significant. In rare cases, the usual intensive care techniques fail to maintain organ oxygenation with a risk of multiorgan dysfunction. Although extracorporeal membrane oxygenation (ECMO) is a difficult and risky procedure, it can be proposed as life-saving. Four children with either acute pulmonary (three) or cardiac (one) failure after LT, and the criteria that decided the use of ECMO (level of ventilation and results, dosage of inotropic drugs, cardiac ultrasound, blood lactate) were retrospectively reported...

Cardiogenic shock is a life-threatening presentation of severe heart failure with high morbidity and mortality. Given the modest increased in cardiac output and neutral/negative survival benefits with today's available inotropes (namely, dobutamine and milrinone), the use of mechanical circulatory support (MCS) has increased dramatically over the past 2 decades. In this review article, we discuss the physiologic concept, clinical evidence of benefit, and current use and indications/potential complications of the four most commonly used devices for MCS: intra-aortic balloon pump, Impella percutaneous ventricular assist device, TandemHeart, and extracorporeal membrane oxygenation (ECMO)...

BACKGROUND: Heart failure (HF) is a chronic condition causing nearly 1 million hospital admissions annually in the United States with 25% of patients rehospitalized within 30 days. INTRODUCTION: The purpose of this study was to investigate whether telemanagement of HF patients throughout the post-acute continuum of care would reduce rehospitalization rates and improve patient self-care knowledge and satisfaction. MATERIALS AND METHODS: HF patients discharged to a skilled nursing facility (SNF) received telemanagement by HF clinicians with opportunity for continuation at home with assistance of home healthcare (HHC) nurses...
