Right heart failure (RHF) after left ventricular assist device (LVAD) is associated with poor outcomes. Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) defines RHF as elevated right atrial pressure (RAP) plus venous congestion. The purpose of this study was to examine the diagnostic performance of the noninvasive INTERMACS criteria using RAP as the gold standard. We analyzed 108 patients with LVAD who underwent 341 right heart catheterizations (RHC) between January 1, 2006, and December 31, 2013...

End-stage heart failure (HF) is associated with renal failure (RF). This study aimed to determine the prognostic influence of RF and post-operative hemodialysis on short-term survival following left ventricular assist device (LVAD) implantation. This retrospective study includes 68 patients undergoing LVAD treatment. Kidney function was recorded prior to LVAD implantation, immediately afterwards and after 30 days, noting the need for hemodialysis. Median pre-operative Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) classification was 3...

INTRODUCTION: Left ventricular assist devices as long-term mechanical circulatory support are increasingly used as an option for medically refractory advanced heart failure. Heartmate III is one of the alternative devices for circulatory support in those patients. OBJECTIVES: Analyze a two years Heartmate III implantation Program. METHODS: From November 2015 to August 2017, Heartmate III was implanted in 16 patients with chronic end-stage heart failure, in 81% (n = 13) as a bridge to transplant and 19% (n = 3) as destination therapy...

OBJECTIVES: Standard implantation of the HeartWare left ventricular assist system is performed using the full sternotomy approach. However, successful implantation of left ventricular assist devices in patients with a previous median sternotomy, especially in high-risk patients, remains challenging. Herein, we compared the HeartWare left ventricular assist system implantation by thoracotomy with anastomosis of the outflow graft to the descending aorta with the standard sternotomy approach...

Use of durable, continuous-flow left ventricular assist devices (LVADs) has expanded rapidly, although data are limited regarding optimization strategies before LVAD implantation. We examined current use of intra-aortic balloon pumps (IABPs) before LVAD implantation and compared outcomes of patients with IABP use to those without. We analyzed data from the Interagency Registry for Mechanical Assisted Circulatory Support (INTERMACS) on patients who underwent LVAD implantation between 2006 and 2014. We limited the analysis to patients with an admitting diagnosis of LVAD placement...

In cardiogenic shock patients with Interagency Registry for Mechanical Circulatory Support (INTERMACS) level 1, the need for temporary circulatory support is a predictor and modifier of patient outcome. Because this group includes patients with and without cardiopulmonary resuscitation (CPR) and is thus very heterogeneous, we investigated whether a further subclassification is useful. We compared 30-day and 1-year mortality of patients who underwent left ventricular assist device implantation after extracorporeal CPR with the aid of an extracorporeal life support system (CPR+ group; n = 40) with cardiogenic shock patients in which the extracorporeal life support system was implanted under non-CPR conditions (CPR- group, n = 68)...

BACKGROUND: Pediatric ventricular assist device (VAD) support as bridge to transplant has improved waitlist survival, but the effects of pre-implant status and VAD-related events on post-transplant outcomes have not been assessed. This study is a linkage analysis between the PediMACS and Pediatric Heart Transplant Study databases to determine the effects of VAD course on post-transplant outcomes. METHODS: Database linkage between October 1, 2012 and December 31, 2015 identified 147 transplanted VAD patients, the primary study group...

BACKGROUND: The interleukin-33 (IL-33)/suppressor of tumorigenicity 2 (ST2) pathway is suggested to play an important role in fibrosis, remodelling and the progression of heart failure (HF). Increased soluble (sST2) levels are associated with adverse outcome in the average HF population. Less is known about sST2 levels in end-stage HF. Therefore, we studied sST2 levels in end-stage HF and the effect of unloading by left ventricular assist device (LVAD) support on sST2 levels. METHOD AND RESULTS: Serial plasma measurements of sST2 were performed pre-implantation and 1, 3 and 6 months after (LVAD) implantation in 38 patients...

BACKGROUND: The ROADMAP study showed survival with improved functional status was better with left ventricular assist device (LVAD) therapy compared with optimal medical management (OMM) in ambulatory, non-inotrope-dependent (INTERMACS [IM] Profile 4 to 7) patients. To study more balanced cohorts and better define which patients may benefit from implantation of an LVAD, we re-evaluated the patients enrolled in ROADMAP when stratified by INTERMACS profile (Profile 4 and Profiles 5 to 7)...

Refractory right ventricular failure (RVF) after implantation of left ventricular assist device (LVAD) is a dramatic complication. The addition of right ventricular assist device (RVAD) may improve RV recovery and lead to improve outcomes. From February 2012 to September 2014, 44 patients received a HeartMate II. These patients were retrospectively compared in two groups according to early liberal implantation of an extracorporeal membrane oxygenation (ECMO) used as a RVAD established between a femoral vein and the pulmonary artery...

BACKGROUND: Historically, the "temporary" or short-term ventricular assist device (VAD) was used only as a quick bridge to recovery for children with an acute process. In the current era, the devices that were originally used for temporary support are now being used to support children for longer durations and for a variety of indications. In this study we aimed to describe the overall use, patients' characteristics and outcomes of "temporary" VAD use in children. METHODS: The Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS) is a National Institutes of Health-supported national registry for United States Food and Drug Administration-approved VADs in patients <19 years of age at the time of VAD implantation (either durable or temporary VAD)...
