BACKGROUND: Supraphysiologic shear stress from continuous-flow left ventricular assist devices (LVADs) accelerates von Willebrand factor (vWF) degradation and predisposes patients to nonsurgical bleeding. It is unknown whether unique design characteristics of LVADs differentially affect vWF degradation. We tested the hypothesis that the centrifugal-flow EVAHEART (Evaheart, Houston, TX) left ventricular assist system (LVAS), which was designed to minimize shear stress (low operational revolutions per minute [rpm], larger flow gaps, low shear stress, flat H-Q curve), reduced vWF degradation versus the axial-flow HeartMate II (Thoratec, Pleasanton, CA) LVAD...

BACKGROUND: When valve replacement is required in patients with end-stage renal disease (ESRD), it is not clear if mechanical or bioprosthetic valve selection is better. We compared outcomes between ESRD patients who underwent either mechanical or biologic valve replacements at our institution. METHODS: All patients with ESRD who underwent either mitral or aortic valve replacement from 2002 to 2014 at our institution were reviewed (n = 215; mechanical = 64, biological = 151)...

BACKGROUND: Right ventricular (RV) adaptation to afterload is crucial for patients undergoing continuous-flow left ventricular assist device (cf-LVAD) implantation. We hypothesized that stratifying patients by RV pulsatile load, using pulmonary arterial compliance (PAC), and RV response to load, using the ratio of central venous to pulmonary capillary wedge pressure (CVP:PCWP), would identify patients at high risk for early right heart failure (RHF) and 6-month mortality after cf-LVAD...

OBJECTIVE: Patients undergoing emergency peripheral arteriovenous extracorporeal life support were evaluated for lower-extremity complications on the basis of the ipsilateral limb perfusion strategy. METHODS: In a retrospective review of patients receiving extracorporeal life support (2008-2013), 105 of 250 underwent femoral extracorporeal life support. For ipsilateral lower-extremity perfusion, patients underwent no superficial femoral artery cannulation (n = 35), percutaneous superficial femoral artery cannulation (n = 23), or open superficial femoral artery cannulation (n = 47)...

BACKGROUND: The aim of this study was to evaluate institutional volume-outcome relationships in extracorporeal membrane oxygenation (ECMO) with subanalyses of ECMO in patients with a primary diagnosis of respiratory failure. METHODS: All institutions with adult ECMO discharges in the Nationwide Inpatient Sample from 2002 to 2011 were evaluated. International Classification of Diseases (ninth revision) codes were used to identify ECMO-treated patients, indications, and concurrent procedures...

BACKGROUND: In a trial comparing coronary-artery bypass grafting (CABG) alone with CABG plus mitral-valve repair in patients with moderate ischemic mitral regurgitation, we found no significant difference in the left ventricular end-systolic volume index (LVESVI) or survival after 1 year. Concomitant mitral-valve repair was associated with a reduced prevalence of moderate or severe mitral regurgitation, but patients had more adverse events. We now report 2-year outcomes. METHODS: We randomly assigned 301 patients to undergo either CABG alone or the combined procedure...

BACKGROUND: Nonsurgical bleeding is a frequent complication of continuous-flow left ventricular assist device (LVAD) support. Abnormal von Willebrand factor (vWF) metabolism plays a major role. However, the relationship between LVAD speed and vWF degradation is unknown. Recent evidence has demonstrated that supraphysiologic shear stress from continuous-flow LVADs accelerates vWF degradation and causes an acquired vWF deficiency and bleeding. To manage LVAD-associated bleeding, it has been proposed that reduced LVAD speed may decrease shear stress and thereby reduce pathologic vWF metabolism...

Sudden cardiac death (SCD) is a common cause of death in the general population, occurring in 300,000 to 350,000 people in the United States alone. Currently, there are no data supporting implantable cardioverter-defibrillator therapy in patients who underwent orthotopic heart transplant (OHT) with low left ventricular ejection fraction (LVEF). In this retrospective study, we included all patients who underwent primary OHT at our institution from 2007 to 2013. We compared the cause of death in patients who underwent OHT and evaluated the correlation of the cause of death and the patients' LVEF...

BACKGROUND: Heart transplantation is the gold-standard treatment for end-stage heart failure. Short- and long-term outcomes have been excellent, but the shortage of organs persists. The number of potential recipients who die while awaiting orthotopic heart transplantation increases yearly. In 2004, the label "high-risk donor" (HRD) was applied, by the United Network for Organ Sharing (UNOS), to any organ donor who met the Centers for Disease Control (CDC) criteria for behavior that put them at high risk of infection...

REVIEW
Arman Kilic, Michael A Acker, Pavan Atluri
Left ventricular assist devices (LVAD) will undoubtedly have an increasing role due to the aging population, anticipated concomitant increase in the prevalence of end-stage heart failure, and improvements in LVAD technology and outcomes. As with any surgical procedure, LVAD implantation is associated with an adverse event profile. Such complications of LVAD therapy include bleeding, infection, pump thrombosis, right heart failure, device malfunction, and stroke. Although each has a unique management, early recognition and diagnosis of these complications is uniformly paramount...

BACKGROUND: The "high-risk donor" (HRD) label was applied to donors who met the Centers for Disease Control and Prevention criteria for high-risk behavior in 2004. The number of potential recipients who die awaiting orthotopic heart transplantation (OHT) has increased. Despite organ shortages, HRD grafts are often declined given infectious concerns. We hypothesized that recipients would have equivalent outcomes. METHODS: We retrospectively analyzed the United Network of Organ Sharing adult heart transplant data from June 2004 to December 2013...

This study evaluates contemporary trends in the use and outcomes of adult patients undergoing extracorporeal membrane oxygenation (ECMO) in U.S. hospitals. All adult discharges in the Nationwide Inpatient Sample database during the years 2002-2012 that included ECMO were used to estimate the total number of U.S. ECMO hospitalizations (n = 12,407). Diagnostic codes were used to group patients by indication for ECMO use into postcardiotomy, heart transplant, lung transplant, cardiogenic shock, respiratory failure, and cardiopulmonary failure...
