Adequate physical and functional performance is an important prerequisite for renewed participation and integration in self-determined private and (where appropriate) professional lives following left ventricular assist device (LVAD) implantation. During cardiac rehabilitation (CR), individually adapted exercise programs aim to increase exercise capacity and functional performance. A retrospective analysis of cardiopulmonary exercise capacity and functional performance in LVAD patients at discharge from a cardiac rehabilitation program was conducted...

Pump thrombosis and hemolysis in patients with left ventricular assist devices (LVADs) are associated with significant morbidity and mortality. Intensification of anticoagulation has been suggested as potential therapy, with mixed results. The aim of this study is to assess the safety and efficacy of adding eptifibatide with or without an anticoagulation agent in managing patients with LVAD presenting with hemolysis and suspected pump thrombosis. This retrospective single center study included all patients who presented with their first episode of suspected pump thrombosis and were treated with eptifibatide with or without an anticoagulant between March 1, 2011 and July 30, 2015...

BACKGROUND: Patient-specific anatomy may influence the final intraventricular positioning of inflow cannula in left ventricular assist device (LVAD) recipients. An association exists between such positioning and clinical outcomes (specifically, orientation toward the interventricular septum has negative prognostic implications). Alternative commercially available LVADs are characterized by markedly different design, with potential consequences on intrathoracic fitting among individual patients...

BACKGROUND: As support times for left ventricular assist devices (LVADs) become longer, several complications requiring device exchange may occur. To our knowledge, this is the first Canadian report regarding implantable LVAD exchange. METHODS: We retrospectively reviewed the cases of consecutive, unique patients implanted with an LVAD between June 2006 and October 2015 at Toronto General Hospital. RESULTS: In total, 122 patients were impanted with an LVAD during the study period...

New generation devices for long-term mechanical circulatory support are centrifugal pumps having fully magnetically levitated rotors to reduce blood trauma. Recently, the novel HeartMate 3 was cleared for clinical application in Switzerland. In two Swiss University Hospitals part of the "Lausanne-Geneva Transplantation Network," 10 consecutive patients in end-stage heart failure received the HeartMate 3. Device implantation criteria were persistent low output syndrome despite optimal medical treatment. The primary end-point of the study was survival or transplantation to 90 days on the device...

The field of mechanical circulatory support has made great strides in the preceding 2 decades. Although pediatric mechanical circulatory support has lagged behind that of adults, the gap between them is expected to close soon. The only device currently approved by the US Food and Drug Administration for use in children is the Berlin Heart EXCOR ventricular assist device (VAD). The prospective Berlin Heart Investigational Device Exemption Trial demonstrated good outcomes, such as bridge to transplantation or recovery, in ~90% of children supported with this device...

Electromagnetic interferences between implantable cardioverter/defibrillators (ICD) and left ventricular assist devices (LVAD) impacting telemetry have been described in previous generations of ICD as well as LVAD, but have been predominantly overcome in current ICD generations. After introduction of a new fully magnetically levitated centrifugal continuous-flow circulatory pump, we report a case of tenacious telemetry interference between the HeartMate 3 LVAD and an ICD after battery exchange to an Iforia 5...

Patients with mechanical aortic valves are generally contraindicated for left ventricular assist device (LVAD) insertion because the prosthetic valve often becomes fixed in closed position. A 41-year-old woman with mechanical aortic valve prosthesis experienced sudden chest pain and developed cardiogenic shock. A paracorporeal pulsatile LVAD and a monopivot centrifugal pump as a right VAD (RVAD) were implanted. The mechanical aortic valve was intentionally left in place. Soon after the operation, LVAD support was discontinued daily for few seconds to allow the mechanical aortic valve to open and to avoid thrombus formation...

Left ventricular assist devices (LVAD) improve survival in patients with advanced heart failure but are prone to various complications causing mechanical failure. Inflow cannula stenosis presents a particular challenge often requiring invasive surgical repair. We present a novel transcatheter approach for stent delivery to successfully restore hemodynamic function in a patient with inflow cannula stenosis of a HeartMate II LVAD. © 2017 Wiley Periodicals, Inc.

BACKGROUND: Timing of left ventricular assist device (LVAD) implantation in advanced heart failure patients not on inotropes is unclear. Relevant prediction models exist (SHFM [Seattle Heart Failure Model] and HMRS [HeartMate II Risk Score]), but use in this group is not established. METHODS AND RESULTS: ROADMAP (Risk Assessment and Comparative Effectiveness of Left Ventricular Assist Device and Medical Management in Ambulatory Heart Failure Patients) is a prospective, multicenter, nonrandomized study of 200 advanced heart failure patients not on inotropes who met indications for LVAD implantation, comparing the effectiveness of HeartMate II support versus optimal medical management...

Although biventricular heart failure has been successfully managed with dual continuous-flow ventricular assist devices, the long-term use of 2 mechanically dissimilar pumps has traditionally been discouraged. We present the case of a 52-year-old man whose treatment with a HeartMate II left ventricular assist device was complicated by right ventricular failure, necessitating the implantation of a long-term right ventricular assist device. A HeartWare left ventricular assist device was placed along the right ventricular base to avoid interference with the HeartMate II housing...

BACKGROUND: The implantation of rotary blood pumps as ventricular assist devices (VADs) has become a viable therapy for quite a number of patients with end-stage heart failure. However, these rotary blood pumps cause adverse events that are related to blood trauma. It is currently believed that turbulence in the pump flow plays a significant role. But turbulence has not been measured to date because there is no optical access to the flow space in rotary blood pumps because of their opaque casings...

BACKGROUND: Heart failure is a major cause of mortality and morbidity, particularly among patients with advanced disease and no access to cardiac transplantation. LVAD implantation is not only a bridge-to-transplantation option for patients awaiting a heart donor, but is often used as bridge-to-destination therapy in patients unsuited for transplantation for various reasons. LVAD infection is considered the second-most common cause of death in patients who survive the initial 6 months on LVAD support...

BACKGROUND: Left ventricular assist device (LVAD) exit-site infections represent a major challenge in the era of modern LVADs. Infections caused by Pseudomonas are particularly difficult to treat due to limited antibiotic susceptibility. We hypothesized that keeping the LVAD exit site dry while bathing could result in reduced incidence of Pseudomonas infections. METHODS: Starting in April 2013, all patients who underwent placement of HeartMate II (HM II) LVAD were instructed not to take conventional showers and to keep the exit site dry while bathing...

OBJECTIVES: The purpose of this study was to investigate the differential impact of the 2 most commonly available left ventricular assist device (LVAD) types on the right (RV) and left (LV) ventricles using 3-dimensional (3D) echocardiography-based analysis of ventricular morphology. BACKGROUND: LVADs have emerged as common therapy for advanced heart failure. Recent data suggest that the heart responds differently to speed settings in the 2 main devices available (HeartMate II [HMII], St Jude Medical, Pleasanton, California, and HVAD, HeartWare International, Framingham, Massachusetts)...
