BACKGROUND: Mediastinal infections are a potentially devastating complication of cardiac operations. This study analyzed the frequency, risk factors, and perioperative outcomes of mediastinal infections after cardiac operations. METHODS: In 2010, 5,158 patients enrolled in a prospective study evaluating infections after cardiac operations and their effect on readmissions and mortality for up to 65 days after the procedure. Clinical and demographic characteristics, operative variables, management practices, and outcomes were compared for patients with and without mediastinal infections, defined as deep sternal wound infection, myocarditis, pericarditis, or mediastinitis...

BACKGROUND: Aortic regurgitation is a prevalent, detrimental complication of left ventricular assist devices (LVADs). The altered hemodynamics of LVADs results in aortic valves (AVs) having distinct mechanical stimulation. Our hypothesis was that the altered AV hemodynamics modulates the valve cells and matrix, resulting in changes in valvular mechanical properties that then can lead to regurgitation. METHODS: AVs were collected from 16 LVAD and 6 non-LVAD patients at time of heart transplant...

Postoperative right-sided heart failure (RHF) is a common complication after continuous-flow left ventricular assist device implantation. Studies have examined RHF in the perioperative period, but few have assessed late-onset RHF. We analyzed the incidence of early and late RHF in patients with HeartMate II and HeartWare left ventricular assist devices and associated morbidity, mortality, and independent predictors of RHF. We retrospectively analyzed records of 526 patients with chronic heart failure who underwent continuous-flow left ventricular assist device implantation; 147 (27...

REVIEW
Leslie Raffini
The evolution of devices for mechanical circulatory support (MCS), including ventricular assist devices (VADs) for patients with heart failure and extracorporeal membrane oxygenation (ECMO) for patients with acute cardiac or respiratory failure, has improved survival for subsets of critically ill children and adults. The devices are intricate and complex, allowing blood to bypass the heart or lungs (or both). As blood flows through these artificial devices, normal hemostasis is disrupted, coagulation is promoted, and in the absence of anticoagulation, a thrombus may form in the device, resulting in device failure or embolic stroke...

The association of an implantable cardioverter defibrillator (ICD) with survival in patients with left ventricular assist devices (LVADs) is not well understood. We evaluated all-cause mortality by the presence of an ICD at the time of LVAD implantation, or by ICD implantation after LVAD placement in 191 patients, using Kaplan-Meier survival analyses and Cox models with multivariate adjustment. During the median follow-up of 23 months, 33 of 129 patients (26%) with an ICD and 17 of 62 patients (27%) without an ICD died...

Quality of life and mental health of patients with severe heart failure with or without technical support for the left cardiac ventricle - a cross-sectional study Objectives: Chronic heart failure is associated with reduced quality of life (QoL) and poor prognosis. Support via a left ventricular assist device (LVAD) is an alternative to optimised medical management for patients with advanced heart failure. This study evaluated health-related QoL with both therapy options. METHODS: In this consecutive cross-sectional study, patients with LVAD support (n = 50) and patients with optimised medical management (n = 50) were interviewed comprehensively about various domains of QoL, emotional stress, perceived self-efficacy, social support, life satisfaction, and communication...

OBJECTIVES: Prolonged support with a left ventricular assist device (LVAD) has evolved as an alternative treatment strategy for patients with end-stage heart disease. This requires a shift in focus on sexual activity and psychosocial outcomes in patients with an LVAD and their partners. METHODS: This cross-sectional study was designed to capture Sexual Activities in Left Ventricular Assist Device Patients Or PaRtners (SALVADOR) perceptions on illness-related changes in the quality of sexual activity and its impact on quality of life, anxiety and depression using standardized patient-reported outcome scales (Sexual Adjustment Scale, 36-Item Short Form Health Survey, Hospital Anxiety and Depression Scale)...

The last decade has seen considerable growth in the use of left ventricular assist devices (LVAD), in end-phase heart failure treatment. The indications, contraindications and implantation techniques are well-defined. However, information about mechanical support for right ventricular failure is lacking. The aim of this communication is to present alternative techniques for implantation of short- and longterm right ventricular assist devices. Implanting the device in the right atrium has certain advantages when compared with the right ventricle...

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...

Psychosocial factors have been show to impact survival and outcomes in a number of different diseases, including heart failure and patients receiving heart transplantation. With the increasing utilization of these devices, it is important to identify risk factors that could impact post-left ventricular assist device (LVAD) outcomes. This study was a single center, retrospective analysis of 238 patients who underwent implantation of a LVAD between July 27, 2004, and July 21, 2016, at The University of Nebraska Medical Center...

The aims of this analysis were to characterize the burden and timing of bleeding events in females versus males on left ventricular assist device (LVAD) support. A single-center retrospective review of 375 patients receiving continuous-flow LVADs was performed. Bleeding events included gastrointestinal, naso-oropharyngeal, gynecologic (GYN), intracranial hemorrhage (ICH), and mediastinal bleeding. Cox hazard ratios (HRs) [95% CI] and incident event rates for females versus males were calculated. Eighty-four females (22%) and 291 males (78%) received an LVAD...

Driveline or device infection may complicate left ventricular assist device implants, and only curative option may be pump exchange. Replacement with similar device may be liable to reinfection, because pump configuration is such that the new device and driveline may partly lie within the pocket of the previous pump. One approach to overcome this is using a different pump design such that the new pump would lie in a different location from the old pump. We describe treatment of severe HeartMate II (Abbott, [St Jude Thoratec Corp], Pleasanton, CA USA) left ventricular assist device infection by minimally invasive exchange to an intrapericardial HVAD (HeartWare International, Inc, Framingham, MA USA) left ventricular assist device...

Systemic cobaltism related to metal-on-metal total hip arthroplasty has been published in case reports and series with effects on the cardiac, neurologic, endocrine, and immunologic systems. This case report presents a 46-year-old male who underwent bilateral metal-on-metal total hip arthroplasty and subsequently developed cardiomyopathy requiring left ventricular assist device implantation. Intervention with bilateral revision to non-cobalt-containing implants resulted in improved cardiac function. This case report will alert clinicians to the presentation of this rare but devastating complication while also displaying improvement following revision total hip arthroplasty...

Due to the critical roles that platelets play in thrombosis during many biological and pathological events, altered platelet function may be a key contributor to altered hemostasis, leading to both thrombotic and hemorrhagic complications. Platelet adhesion at arterial shear rates occurs through binding to von Willebrand Factor via the glycoprotein (GP) GPIb receptor. GPIb binding can induce platelet activation distinguishable by P-selectin (CD62P) surface expression and αIIbβ3 activation, resulting in platelet aggregation and formation of the primary hemostatic plug to stop bleeding...

The pandemic of heart failure and the limited options for treatment of end-stage disease have resulted in an increase in the utilization of left ventricular assist devices (LVADs). Improvements in device technology and patient survival have led to an expanding population of patients requiring noncardiac surgery while on LVAD therapy, thus leading to a growing need for familiarity with the physiology of these patients. This review describes the functional mechanics of the most prevalent continuous-flow LVAD, the HeartMate II, and focuses on perioperative anesthetic concerns...

Organ donor criteria continue to be extended in an attempt to meet growing demands. Patients with continuous-flow left ventricular assist devices are one group of potential donors being considered. One concern with this group is the effect of continuous flow for a prolonged duration, as opposed to normal pulsatile flow, on end-organ function. We report the 1st case of a liver transplantation from a donor who had a continuous-flow left ventricular assist device for 9 months. The recipient was a 69-year-old woman with a history of cryptogenic cirrhosis and hepatocellular carcinoma...
