BACKGROUND: Axial configuration (AC) and centrifugal configuration (CC) left ventricular assist devices (LVAD) have different flow characteristics, and whether the interaction between device flow configuration and the pre-operative left ventricular internal diastolic diameter (LVIDD) mediates adverse events after LVAD implantation is unknown. METHODS: We queried 9,424 continuous-flow LVAD recipients who received LVADs from April 2008 to June of 2015 in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS)...

Heart failure patients with pacemaker or defibrillator-associated endocarditis in cardiogenic shock have few treatment options. We present a case of an INTERMACS I patient who developed device infection, sepsis, bacterial pericarditis and heparin-induced thrombocytopenia. The patient was stabilized with extracorporeal membrane oxygenation and successfully transplanted.

Patient selection is a key determinant of clinical outcomes after LVAD placement in patients with end stage heart failure. The HMRS has been proposed to facilitate risk stratification and patient selection for continuous flow pumps. This study retrospectively assessed the performance of HMRS in predicting 90-day and 1-year mortality in patients within the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS). 11,523 INTERMACS patients who received a continuous flow LVAD between 2010 and 2015 were retrospectively categorized per their calculated HMRS to predict their 90-day and 1-year risk of mortality...

Insertion of a left ventricular assist device (LVAD) improves survival and quality of life (QOL) in patients with class IV heart failure failing medical management. However, QOL and survival of patients bridged to LVAD with extracorporeal membrane oxygenation (ECMO) is unknown. Between July 2008 and June 2014, 213 patients underwent insertion of HeartMate II LVAD at 2 VAD centers without a bridge with a temporary VAD. ECMO was used as a bridge prior to LVAD insertion in 22 INTERMACS 1 patients (ECMO-VAD group)...

BACKGROUND: INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) profiles provide important prognostic information for patients with advanced heart failure (HF) receiving mechanical support. The value of INTERMACS profiling has not been shown for patients followed on medical therapy for advanced HF at centers that also offer mechanical circulatory support. METHODS AND RESULTS: This prospective, observational study enrolled 166 patients with chronic New York Heart Association class III-IV HF, ejection fraction ≤30%, and ≥1 HF hospitalization in the previous year, excluding patients listed for transplant or receiving chronic intravenous inotropic therapy...

OBJECTIVES: This study investigated how small patient size affects clinical outcomes in patients implanted with a continuous flow left ventricular assist device (CFLVAD). BACKGROUND: The development of smaller CFLVADs has allowed ventricular assist device (VAD) use in anatomically smaller patients; however, limited outcome data exist regarding CFLVAD use in patients with a body surface area (BSA) ≤1.5 m(2). METHODS: All CFLVAD patients entered in the Interagency Registry for Mechanically Assisted Circulatory Support registry April 2008 to September 2013 and with BSA data were included...

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...

BACKGROUND: Earlier studies have demonstrated disparities in patients undergoing left ventricular assist device (LVAD) implantation when stratified according to sex and race. Because very few data exist from large investigations, we reviewed data from the registry of the Mechanical Circulatory Support Research Network. METHODS: Between May 2004 and September 2014, 734 patients underwent primary LVAD implantation at our institutions. Median age at implant was 57 (range 18 to 82) years and there were 577 males (80%)...

BACKGROUND: Calcium and phosphate are central for myocardial contractility and energy metabolism, and low levels of the calciotropic hormone 1,25-dihydroxyvitamin D (1,25(OH)2D), as well as high levels of the phosphaturic hormone fibroblast growth factor (FGF)-23, are independently associated with poor clinical outcome in heart failure (HF) patients. We therefore aimed to investigate the postoperative time course of the aforementioned hormones in HF patients supported with a left-ventricular assist device (LVAD) implant...

BACKGROUND: Mechanical circulatory support (MCS) is a widely available management strategy. No studies have described sex differences in both extracorporeal and durable MCS. We analyzed sex-related differences of in-hospital outcomes for extracorporeal and durable MCS using administrative hospital data. METHODS: In total, 134.5 million hospital records between 1994 and 2012 were screened for placement of MCS using procedure codes of the International Classification of Diseases-9, Clinical Modification...

Centrifugal (CFG) and axial flow (AX) left ventricular assist devices have different hydrodynamic properties that may impact the effectiveness of left ventricular unloading. We sought to determine whether patients implanted with the HeartWare HVAD (CFG) and HeartMate II (AX) had a similar degree of hemodynamic support by comparing parameters measured using echocardiography and right heart catheterization. Using our prospectively collected database, we identified 268 patients implanted with the AX and 93 with the CFG...

BACKGROUND: The number of centers with left ventricular assist device (LVAD) research programs focused on cardiac recovery is very small. Therefore, this phenomenon has been reported in real-world multi-center registries as a rare event. OBJECTIVES: This study evaluated the incidence of cardiac recovery with an a priori LVAD implantation strategy of bridge-to-recovery (BTR) and constructed a recovery predictive model. METHODS: The study included LVAD recipients registered in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS)...

BACKGROUND: Cardiogenic shock (CS) has a poor prognosis. The heterogeneity in the mortality through different subgroups suggests that some factors can be useful to perform risk stratification and guide management. We aimed to find predictors of in-hospital mortality in these patients. METHODS: We analyzed all cases of cardiogenic shock due to medical conditions admitted in our intensive acute cardiovascular care unity from November 2010 till November 2015. Clinical, biochemical and hemodynamic variables were registered, as was the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) profile at 24h of CS diagnosis...

There is insufficient data on patients with small body size to determine if this should be considered a risk factor for continuous-flow left ventricular assist device (CF-LVAD) support. We sought to evaluate survival outcomes, adverse events, and functional status of CF-LVAD patients with body surface area (BSA) <1.5 m in a large national registry. Adults with BSA < 1.5 m (n = 128) implanted with a HeartMate II (HMII)-LVAD from the Interagency Registry for Mechanically Assisted Circulatory Support registry from April 2008 to December 2012 formed this cohort...

BACKGROUND: A left ventricular assist device (LVAD) improves survival and quality of life for many, but not all, patients with end-stage heart failure who are ineligible for transplantation. We sought to evaluate the frequency of poor outcomes using a novel composite measure that integrates quality of life with mortality. METHODS AND RESULTS: Within the INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) national registry, poor outcome was defined as death or an average Kansas City Cardiomyopathy Questionnaire <45 during the year after LVAD (persistently limiting heart failure symptoms and poor quality of life)...
