BACKGROUND: The intravascular ventricular assist system (iVAS) is a new, minimally invasive, ambulatory counterpulsation heart assist system delivered via the subclavian artery and powered by a portable driver. It is designed for recovery, bridge to transplantation (BTT) or for prolonging medical therapy. We report the first-in-human (FIH) experience with iVAS. METHODS: This is a prospective, non-randomized single arm, U.S. Food and Drug Administration (FDA)-approved early feasibility trial in patients listed for cardiac transplantation...

BACKGROUND: The Jarvik 2000 ventricular assist device features a miniaturized intraventricular pump and an intermittent low-speed function that facilitates aortic valve opening. Despite its long history, little is known about the Jarvik device with regard to post-implantation outcomes. METHODS: Prospectively collected data from 13 participating hospitals were extracted from the Japanese Registry for Mechanically Assisted Circulatory Support database to analyze mortality, morbidity and de-novo aortic regurgitation...

OBJECTIVES: The European Registry for Patients with Mechanical Circulatory Support (EUROMACS) was founded in Berlin, Germany. EUROMACS is supported fully by the European Association for Cardio-Thoracic Surgery (EACTS) and, since 2014, has functioned as a committee of the EACTS. The purpose of having the EUROMACS as a part of the EACTS is to accumulate clinical data related to long-term mechanical circulatory support for scientific purposes and to publish annual reports. METHODS: Participating hospitals contributed surgical and cardiological pre-, peri- and long-term postoperative data of mechanical circulatory support implants to the registry...

Advances in mechanical circulatory support have been critical in bridging patients awaiting heart transplantation. In addition, improvement in device durability has enabled left ventricular assist device therapy to be applied as destination therapy in those not felt to be transplant candidate. Because of the increasing complexity of patients, there continues to be a need for alternative strategies for device implantation to bridge high-risk patients awaiting heart transplantation, wherein the risks of numerous previous sternotomies may be prohibitive...

Device thrombosis is a devastating complication of left ventricular assist devices. The definitive treatment has been device exchange or explant. Evidence of increasing morbidity and mortality with device exchange has shifted strategies toward conservative management. In this report, we detail the use of thrombolytics as salvage therapy in a patient with an occlusive HeartWare ventricular assist device (HeartWare Inc., Framingham, MA) thrombus, resulting in long-term survival without further intervention.

Endoventricular thrombolytic procedure (ETP) has been used to treat continuous-flow left ventricle assist device (CF-LVAD) thrombosis. The study aims to investigate the occurrence of complications after ETP. Data were retrospectively reviewed and analyzed in a series of patients who underwent CF-LVAD followed by ETP. Since November 2010, 20 patients underwent HeartWare CF-LVAD implantation at our institute. Four patients (20%) developed pump thrombosis and underwent a total of nine ETPs with tissue plasminogen activator infused into the left ventricle...

OBJECTIVES: Right ventricular (RV) failure complicating left ventricular assist device implantation is associated with increased mortality. Despite a lack of supporting evidence, venoarterial extracorporeal membrane oxygenation (ECMO) support is increasingly being used as an alternative to traditional temporary RV support. We report our institutional experience with ECMO-facilitated RV support after left ventricular assist device implantation. METHODS: We retrospectively reviewed the concept of temporary ECMO support for perioperative RV failure in 32 consecutive left ventricular assist device (mean age 52 ± 14 years; male 84...

BACKGROUND: Heart transplantation remains the definitive therapy for patients with advanced heart failure; however, owing to limited donor organ availability and long wait times, continuous-flow left ventricular assist devices (LVADs) have become standard therapy. METHODS: This review summarizes the history, progression, function, and basic management of LVADs. Additionally, we provide some clinical pearls and important caveats for managing this unique patient population...

BACKGROUND: This study describes the impact of continuous-flow left-ventricular-assist device (CF-LVAD)-related complications on postoperative outcomes. METHODS: The United Network for Organ Sharing (UNOS) heart transplant follow-up data from 2005 to 2015 were obtained. CF-LVAD patients who were bridged to transplant were studied. Device-related complications (DRCs) at patient's last follow-up before transplantation were reported in 5 categories: device thrombosis (B1), infection (B2), device malfunction (B3), life-threatening arrhythmias (B4), and others (B5)...

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...

Cardiac arrest in patients on mechanical support is a new phenomenon brought about by the increased use of this therapy in patients with end-stage heart failure. This American Heart Association scientific statement highlights the recognition and treatment of cardiovascular collapse or cardiopulmonary arrest in an adult or pediatric patient who has a ventricular assist device or total artificial heart. Specific, expert consensus recommendations are provided for the role of external chest compressions in such patients...

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...

BACKGROUND: The HeartMate 3 Left Ventricular Assist System (LVAS) (St. Jude Medical Inc., St Paul, MN) with full magnetic levitation allows for wide and consistent blood flow paths and an artificial pulse designed for enhanced hemocompatibility. The HeartMate 3 received market approval in the European Union in 2015 following completion of a multicenter study. After reaching the 6-month study endpoint, patients continue to be followed for 2 years with the 1-year results presented herein...
