BACKGROUND: The implantation of rotary blood pumps as ventricular assist devices (VADs) has become a viable therapy for quite a number of patients with end-stage heart failure. However, these rotary blood pumps cause adverse events that are related to blood trauma. It is currently believed that turbulence in the pump flow plays a significant role. But turbulence has not been measured to date because there is no optical access to the flow space in rotary blood pumps because of their opaque casings...

BACKGROUND: Heart failure is a major cause of mortality and morbidity, particularly among patients with advanced disease and no access to cardiac transplantation. LVAD implantation is not only a bridge-to-transplantation option for patients awaiting a heart donor, but is often used as bridge-to-destination therapy in patients unsuited for transplantation for various reasons. LVAD infection is considered the second-most common cause of death in patients who survive the initial 6 months on LVAD support...

BACKGROUND: Left ventricular assist device (LVAD) exit-site infections represent a major challenge in the era of modern LVADs. Infections caused by Pseudomonas are particularly difficult to treat due to limited antibiotic susceptibility. We hypothesized that keeping the LVAD exit site dry while bathing could result in reduced incidence of Pseudomonas infections. METHODS: Starting in April 2013, all patients who underwent placement of HeartMate II (HM II) LVAD were instructed not to take conventional showers and to keep the exit site dry while bathing...

OBJECTIVES: The purpose of this study was to investigate the differential impact of the 2 most commonly available left ventricular assist device (LVAD) types on the right (RV) and left (LV) ventricles using 3-dimensional (3D) echocardiography-based analysis of ventricular morphology. BACKGROUND: LVADs have emerged as common therapy for advanced heart failure. Recent data suggest that the heart responds differently to speed settings in the 2 main devices available (HeartMate II [HMII], St Jude Medical, Pleasanton, California, and HVAD, HeartWare International, Framingham, Massachusetts)...

BACKGROUND: Early right ventricular failure (RVF) is common after left ventricular assist device (LVAD) implantation and often leads to increased morbidity and mortality. It is difficult to predict early RVF on the basis of clinical and hemodynamic parameters. We investigated the utility of mean arterial pressure (MAP) to central venous pressure (CVP) ratio in predicting early RVF. METHOD: We analyzed a retrospective cohort of 212 consecutive patients who underwent hemodynamic assessment prior to destination therapy LVAD implantation...

Heart failure (HF) remains a major global burden in terms of morbidity and mortality. Despite advances in pharmacological and resynchronization device therapy, many patients worsen to end-stage HF. Although the gold-standard treatment for such patients is heart transplantation, there will always be a shortage of donor hearts. Areas covered: A left ventricular assist device (LVAD) is a valuable option for these patients as a bridge measure (to recovery, to candidacy for transplant, or to transplant itself) or as destination therapy...

DETAILS OF THE CLINICAL CASE: An aortic valve thrombus (AVT) is a rare complication after HeartMate II implantation. In a 44-year-old man, a large AVT was discovered 6 weeks after implantation of a HeartMate II for severe dilated cardiomyopathy. The aortic valve was permanently closed. DISCUSSION: After a followup of 3 months without embolic events, the patient started a cardiac rehabilitation (CR) program involving aerobic exercise, resistance exercises, group gymnastics, and relaxation exercise, and completed the program without any complications, resulting in a significant functional benefit...

OBJECTIVES: Left ventricular assist device (LVAD) exchange is becoming a standard surgical procedure. The exchange procedure is an opportunity to upgrade patients to a new generation pump that offers advanced reduction of adverse events or longer battery hours. METHODS: We performed an analysis of 6 consecutive patients who underwent LVAD exchange to HeartMate 3 either from a HeartWare or HeartMate (HM) II device. Minimally invasive operations were performed through a lateral thoracotomy...

BACKGROUND: Ischemic stroke and intracranial hemorrhage (ICH) following left ventricular assist device (LVAD) placement are major causes of morbidity. The incidence and mortality associated with these events stratified by device type have not been systematically explored. METHODS: A systematic review of PubMed was conducted from January 2007 through June 2016 for all English-language articles involving HeartMate II (HMII) and HeartWare LVAD patients. Ischemic stroke and/or ICH incidence (events per patient-year) and associated mortality rates were abstracted for each device type...

Acquired von Willebrand disease increases bleeding risk in patients implanted with a continuous-flow left ventricular assist device. Lower aspirin doses decrease the risk of bleeding without an increased risk of embolic events. No published studies in the U.S. have compared the incidence of bleeding and thrombotic events between antithrombotic regimens with and without aspirin. A single-center, retrospective analysis was conducted of adult patients implanted with a HM II. Patients received warfarin and aspirin 81 mg daily or warfarin alone...

BACKGROUND: B-type natriuretic peptide (BNP) is a strong predictor of prognosis in chronic heart failure. We aimed to evaluate the clinical correlates and interpretation of BNP monitoring in LVAD out-patient recipients. METHODS: We performed a prospective study in 136 individuals after HeartMate II LVAD implantation. During follow-up they were divided into group A (severe adverse events requiring hospitalisation), group B (mild to moderate adverse events) and group C (an uneventful course)...
