The sixth annual report of the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) summarizes the first 8 years of patient enrollment. The analysis is based on data from >10,000 patients and updates demographics, survival, adverse events and risk factors. Among patients with continuous-flow pumps, actuarial survival continues to(More)
The 5th annual report of the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) summarizes and analyzes the first 6 years of patient and data collection. The current analysis includes more than 6000 patients and updated risk factors for continuous flow pumps. Among continuous flow pumps, actuarial survival is 80% at 1 year and(More)
OBJECTIVE The aim of this study was to evaluate the incidence, risk factors, and effect on outcomes of right ventricular failure in a large population of patients implanted with continuous-flow left ventricular assist devices. METHODS Patients (n = 484) enrolled in the HeartMate II left ventricular assist device (Thoratec, Pleasanton, Calif)(More)
BACKGROUND Contemporary ventricular assist device therapy results in a high rate of successful heart transplantation but is associated with bleeding, infections, and other complications. Further reductions in pump size, centrifugal design, and intrapericardial positioning may reduce complications and improve outcomes. METHODS AND RESULTS We studied a(More)
BACKGROUND Ventricular assist devices (VADs) are important bridges to cardiac transplantation. VAD support may also function as a bridge to ventricular recovery (BTR); however, clinical predictors of recovery and long-term outcomes remain uncertain. We examined the prevalence, characteristics, and outcomes of BTR subjects in a large single center series. (More)
BACKGROUND Poor medical compliance has been held responsible for a large proportion of deaths occurring subsequent to initial postoperative recovery. However, beyond clinical reports, there has been little empirical examination of this issue, or of the extent to which major psychiatric disorder and failure to adjust to the transplant predict long-term(More)
BACKGROUND Autologous adult stem cell transplantation has been touted as the latest tool in regenerative medical therapy. Its potential for use in cardiovascular disease has only recently been recognized. A randomized study was conducted with a novel epicardial technique to deploy stem cells as an adjuvant to conventional revascularization therapy in(More)
BACKGROUND Despite numerous reports published since the early 1970s, it is frequently asserted that quality of life (QOL) outcomes of transplantation have seldom been investigated and/or that little is known about QOL. This view may have persisted due to lack of adequate cumulation and synthesis of existing data. We performed an exhaustive, quantitative(More)
BACKGROUND The HeartWare left ventricular assist device (HVAD, HeartWare Inc, Framingham, MA) is the first implantable centrifugal continuous-flow pump approved for use as a bridge to transplantation. An infrequent but serious adverse event of LVAD support is thrombus ingestion or formation in the pump. In this study, we analyze the incidence of pump(More)
