Right heart failure is a potentially devastating complication of mechanical circulatory support, occurring at a rate of 0.49 events per 100 patient-months. Pulmonary vasodilators such as phosphodiesterase-5 inhibitors (PDE5i) have been frequently used to unload the right ventricle in left ventricular assist device (LVAD) patients, but there is scant evidence to support this practice. The purpose of this analysis is to provide additional data regarding the safety and efficacy of the PDE5i sildenafil in a real world population of patients supported with LVADs at Washington University in St...

BACKGROUND: Despite the increasing use of ventricular assist devices (VADs), gender differences in indications, hemodynamics, and outcome are not well understood. We examined gender differences and gender-specific predictors for perioperative outcome in patients on ventricular support. METHODS: Multicenter data of 966 patients (median age 55 years, 151 women) from the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) were analyzed. Median follow-up was 1...

Right ventricular (RV) failure remains a major cause of global morbidity and mortality for patients with advanced heart failure, pulmonary hypertension, or acute myocardial infarction and after major cardiac surgery. Over the past 2 decades, percutaneously delivered acute mechanical circulatory support pumps specifically designed to support RV failure have been introduced into clinical practice. RV acute mechanical circulatory support now represents an important step in the management of RV failure and provides an opportunity to rapidly stabilize patients with cardiogenic shock involving the RV...

OBJECTIVES: Aortic insufficiency (AI) after continuous-flow left ventricular assist device (CF-LVAD) implantation has become a highly relevant subject. However, management of pre-existing mild AI is unknown. We examined the fate of pre-existing mild AI during CF-LVAD support. METHODS: From March 2004 to October 2015, 446 consecutive patients received CF-LVAD. Of these, 56 (12.6%) patients with pre-existing mild AI were identified. Outcomes were compared between patients who underwent repair [ n  = 41 (73...

Short-term mechanical circulatory support (MCS) is increasingly used as a bridge to decision in patients with refractory cardiogenic shock. Subsequently, these patients might be bridged to durable MCS either as a bridge to candidacy/transplantation, or as destination therapy. The aim of this study was to review support duration and clinical outcome of short-term MCS in cardiogenic shock, and to analyse application of this technology as a bridge to long-term cardiac support (left ventricular assist device, LVAD) from 2006 till June 2016...

INTRODUCTION AND OBJECTIVES: Most long-term ventricular assist devices (VADs) that are currently implanted are intracorporeal continuous-flow devices. Their main limitations include their high cost and inability to provide biventricular support. The aim of this study was to describe the results of using paracorporeal pulsatile-flow VADs as a bridge to transplant (BTT) in adult patients. METHODS: Retrospective analysis of the characteristics, complications, and outcomes of a single-center case series of consecutive patients treated with the EXCOR VAD as BTT between 2009 and 2015...

BACKGROUND: Current recommendations of antithrombotic therapy for HeartMate II (HMII) patients include the use of both an anticoagulant and an antiplatelet agent. Because bleeding is still the most frequent adverse event, the TRACE (STudy of Reduced Anti-Coagulation/Anti-platelet Therapy in Patients with the HeartMatE II) study was initiated to evaluate the incidence of adverse events in HMII patients on reduced antithrombotic (RT) therapy. METHODS: HMII patients (n = 101) from nine centers were enrolled in the European arm of TRACE and were managed on a single anticoagulant (vitamin K antagonist) with no antiplatelet agents...

Left ventricular assist devices (LVAD) are increasingly used to support patients as they await heart transplantation and as destination therapy for patients with end-stage cardiac failure. While the methods of LVAD implantation have become fairly standardized, early postoperative management of patients receiving these devices remains challenging. One issue that has plagued surgeons, cardiologists, and intensivists caring for patients after LVAD implantation is right heart dysfunction. While many scoring systems have been developed to try to anticipate RV failure, the accuracy of these predictive tools remains low...

BACKGROUND: Stroke is a major cause of mortality after left ventricular assist device (LVAD) placement. METHODS: Prospectively collected data of patients with HeartMate II (n = 332) and HeartWare (n = 70) LVADs from October 21, 2004, to May 19, 2015, were reviewed. Predictors of early (during index hospitalization) and late (post-discharge) ischemic and hemorrhagic stroke and association of stroke subtypes with mortality were assessed. RESULTS: Of 402 patients, 83 strokes occurred in 69 patients (17%; 0...

Selected patients who fail to be weaned off temporary veno-arterial extracorporeal membrane oxygenation support may be considered for long-term left ventricular assist devices.  We describe here a left ventricular assist device implantation technique in patients with prior veno-arterial extracorporeal membrane oxygenation support without the use of a cardiopulmonary bypass machine, which minimizes the intraoperative trauma and blood loss while still meeting all the goals of the standard procedure.

OBJECTIVES: Mechanical circulatory support (MCS) is an established therapy for end-stage heart failure. The EUROMACS registry was created to promote research in patients with MCS and became a committee of the European Association for Cardio-Thoracic Surgery (EACTS) in 2014. Since 1 January 2011, increasing numbers of European centres implanting durable MCS have reported their patient data to EUROMACS. The aim of this study is to compare, as an example of internal quality control, data from a single centre (Bern) with those from the EUROMACS database with respect to mortality rates and preoperative patient characteristics and to describe complications in Bern...

This article reports our 15-year single-center experience with rotary blood pumps (RBPs) as long-term mechanical circulatory support (MCS) with emphasis on outcomes. For more than 15-year period, we have used various RBPs as bridge to transplantation or to myocardial recovery. Our group performed the first human implantation worldwide of RBCs, the MicroMed DeBakey ventricular assist device in November 1998 in a patient with end-stage heart failure who was supported for 47 days until his death. Based on this initial experience, we recognized the feasibility of providing long-term support and since then it has been our primary armamentarium in treating patients with heart failure...

Treatment with the intraaortic balloon pump (IABP) is the most common form of mechanical support for the failing heart. Augmentation of diastolic pressure during balloon inflation contributes to the coronary circulation and the presystolic deflation of the balloon reduces the resistance to systolic output. Consequently, the myocardial work is reduced. The overall effect of the IABP therapy is an increase in the myocardial oxygen supply/demand ratio and thus in endocardial viability.This is an overall synopsis of what we need to know regarding IABP...
