BACKGROUND: The SynCardia total artificial heart (TAH) provides complete circulatory support by replacing both native ventricles. Accepted indications include bridge to transplantation and destination therapy. We review our experience with TAH implantation during a period when axial flow pump became available. METHODS: We retrospectively analyzed the demographics, clinical characteristics and survival of all patients receiving the TAH. RESULTS: From September 2004 to November 2016, 13 patients (12 men, mean age 45 ± 13 yr) received the TAH for refractory cardiogenic shock secondary to idiopathic (56%) or ischemic (17%) cardiomyopathy and to other various causes (33%)...

This case illustrates the potential for systemic cobalt toxicity in non-metal-on-metal bearings and its potentially devastating consequences. We present a 71-year-old male with grinding sensations in his right hip following ceramic-on-ceramic total hip arthroplasty (THA). After diagnosing a fractured ceramic liner, the hip prosthesis was revised into a metal-on-polyethylene bearing. At one year postoperatively, X-rays and MARS-MRI showed a fixed reversed hybrid THA, with periarticular densities, flattening of the femoral head component, and a pattern of periarticular metal wear debris and pseudotumor formation...

INTRODUCTION: In our ageing society, we are at the merge of an expected epidemic of atrial fibrillation (AF). AF management requires an integrated approach, including rate or rhythm control, stroke prevention with anticoagulation and treatment of comorbidities such as heart failure or type 2 diabetes. As such, primary care seems to be the logical healthcare setting for the chronic management of patients with AF. However, primary care has not yet played a dominant role in AF management, which has been in fact more fragmented between different healthcare providers...

BACKGROUND: Although cancer treatment considerably affects cardiovascular health, little is known about how cancer patients are treated for an acute myocardial infarction. We aimed to investigate whether acute myocardial infarction patients with a history of cancer received the same guideline recommended treatment as those acute myocardial infarction patients without and whether they differ with respect to inhospital outcome. METHODS: All patients with ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction, enrolled between 2002 and mid-2015 in the acute myocardial infarction in Switzerland (AMIS Plus) registry with comorbidity data based on the Charlson comorbidity index were analysed...

Cardiogenic shock is a high-acuity, potentially complex, and hemodynamically diverse state of end-organ hypoperfusion that is frequently associated with multisystem organ failure. Despite improving survival in recent years, patient morbidity and mortality remain high, and there are few evidence-based therapeutic interventions known to clearly improve patient outcomes. This scientific statement on cardiogenic shock summarizes the epidemiology, pathophysiology, causes, and outcomes of cardiogenic shock; reviews contemporary best medical, surgical, mechanical circulatory support, and palliative care practices; advocates for the development of regionalized systems of care; and outlines future research priorities...

Persistent pulmonary hypertension (PPHN) is a consequence of failed pulmonary vascular transition at birth and leads to pulmonary hypertension with shunting of deoxygenated blood across the ductus arteriosus (DA) and foramen ovale (FO) resulting in severe hypoxemia, and it may eventually lead to life-threatening circulatory failure. PPHN is a serious event affecting both term and preterm infants in the neonatal intensive care unit. It is often associated with diseases such as congenital diaphragmatic hernia, meconium aspiration, sepsis, congenital pneumonia, birth asphyxia and respiratory distress syndrome...

Sudden cardiac death (SCD) represents a major cause of death among patients with heart failure. While scar-based, macro-reentrant ventricular tachycardia and ventricular fibrillation (VT/VF) is the primary etiology for SCD among patients with ischemic cardiomyopathy, a more diverse set of mechanisms and substrates are likely at play for the diverse group of patients characterized by non-ischemic, dilated cardiomyopathy (NICM). These causes may include scar-based re-entry, but also neurohormonal stimulation (sympathetic, parasympathetic, renin-angiotensin-aldosterone), inflammation, and non-arrhythmic processes occurring in the context of a genetic predisposition...

BACKGROUND: In patients with ventricular tachycardia/fibrillation (VT/VF) electrical storm (ES) undergoing catheter ablation (CA), hypotension due to refractory VT/VF, use of anesthesia and cardiac stunning due to repeated ICD shocks might precipitate acute hemodynamic decompensation (AHD). OBJECTIVE: We evaluated the outcomes of emergent cardiopulmonary support with extracorporeal membrane oxygenation (ECMO) to rescue AHD in patients undergoing CA of ES. METHODS: Between 2010 and 2016, 21 patients with ES (VT in 11 and PVC-triggered VF in 10) were referred for CA and had periprocedural AHD requiring emergent ECMO support...
