OBJECTIVES: Left ventricular assist device (LVAD) support is an increasingly important and successful therapeutic option for patients with end-stage heart failure. As chronic heart failure progresses, the left and right ventricles adapt by enlarging its volume and patients present for LVAD implantation with varying degrees of dilatation. By quantitatively assessing right ventricular (RV) and left ventricular (LV) volumes using 3D transoesophageal echocardiography and correlating the findings with clinical outcomes, we aim to investigate the prognostic value of LV and RV volumes for early survival after LVAD implantation...

The purpose of this study was to analyze the effect of obesity on outcomes after continuous-flow left ventricular assist device (CF-LVAD) implantation. A single-center retrospective analysis was performed on 526 chronic heart failure patients who were implanted with the HeartMate II CF-LVAD (n = 403) or HeartWare HVAD (n = 123) between November 2003 and March 2016. Patients were stratified into 4 groups based on BMI: underweight (< 18.5 kg/m2, n = 18, 3.4%), normal-weight (18.5-25 kg/m2, n = 173, 32...

PURPOSE OF REVIEW: Acute heart failure continues to be a challenge as there is limited benefit of numerous agents that have been tested. Cardiac resynchronization therapy remains standard of care, yet timing and need for implantable cardiac defibrillator has been brought into question with the recent randomized trials. Several recent advances have been made towards management of heart failure both in drug and device therapy. The purpose of this review is to provide an update on the most important recent studies on heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF)...

BACKGROUND: Having a preoperative small left ventricle (LV) has been associated with higher complication and mortality rates after left ventricular assist device (LVAD) implantation; however, the outcomes after continuous-flow LVAD implantation have not been well studied. This is the first large-scale analysis of long-term survival after continuous-flow LVAD implantation in patients with a preoperative small LV. METHODS: Our cohort comprised 511 patients who underwent primary implantation of a HeartMate II (n = 393 [Thoratec, Pleasanton, CA]) or HeartWare HVAD (n = 118 [HeartWare International, Framingham, MA]) at our institution between November 2003 and March 2016...

AIMS: To correlate the dynamics of platelet activation with the development of thromboembolic events in patients with continuous-flow left ventricular assist device (cf-LVAD). METHODS AND RESULTS: The platelet activity state (PAS) assay was utilized to evaluate platelet activation in 68 cf-LVAD patients implanted with the HeartMate II (n = 15, 22%), HeartMate 3 (n = 15, 22%), or HeartWare HVAD (n = 38, 56%). PAS was measured preoperatively, early post-implant, and at long-term follow-up (1, 3, 6, 12, 18, and 24 months post-implant)...

BACKGROUND: Interventions in patients with a left ventricular assist device (LVAD) in the intensive care unit (ICU) are typically performed based on the results of conventional monitoring, such as vital signs and Swan-Ganz catheter (SGC) and LVAD parameters. These variables might not always accurately reflect a patient's cardiac function, volume status, and interventricular septal configuration, however. To assess the accuracy of standard monitoring, we performed routine continuous hemodynamic transesophageal echocardiography (hTEE) to evaluate cardiac function, volume status, and septal position...

BACKGROUND: In long-term left ventricular assist device (LVAD) therapy, recurrent bleeding events may justify cessation of anticoagulation therapy (AT). However, data about THE safety and risks of AT cessation in LVAD patients are scarce.Methods and Results:Between 2010 and 2015, 128 patients received a HeartMate II (HMII). Following recurrent bleeding events, we ceased vitamin K antagonist (VKA) therapy in 13 patients (10%) (no-VKA group). To characterize the hemostatic profile, we performed von Willebrand factor (vWF), platelet function (PF), and other hemostatic tests in all HMII patients...

BACKGROUND: Thrombosis within a left ventricular assist device (LVAD) is a devastating complication that often necessitates device exchange. Few studies have evaluated the relationship between patient anatomy and pump thrombosis. We hypothesize that lateral displacement of the left ventricular (LV) apex increases risk for pump thrombosis. METHODS: All patients who underwent primary implantation of a HeartMate II (HM2) device (Thoratec, Pleasanton, CA) at a single center (2009-2015) were evaluated...

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...

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...

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...

BACKGROUND: Long-term survivors after implantation of left ventricular assist devices (LVADs) are increasing in prevalence. We describe the characteristics and outcomes in patients surviving longer than 4 years on LVAD support. METHODS: We performed a multicenter, retrospective analysis of patients surviving at least 4 years on continuous-flow LVAD (CF-LVAD) support with a HeartMate II at centers participating in the Evolving Mechanical support Research Group. RESULTS: Between 2005 and 2010, 156 long-term survivors were identified with a mean survival of 7...

BACKGROUND: Data on the consequences of acute kidney injury (AKI) after continuous-flow left ventricle assist device (LVAD) implantation are scarce and inconsistent. In this study, we evaluated the incidence, predictors and the impact of AKI on mortality and renal function in the first year after LVAD implantation. METHODS: A retrospective, multicenter cohort study was conducted, including all patients (age ≥18 years) undergoing LVAD implantation (91% with a HeartMate II device and 9% with a HeartWare device)...

We report the case of an HeartMate III left ventricular assist device (LVAD) thrombosis triggered by a shock from an automatic implantable cardioverter defibrillator, releasing a left ventricular thrombus sucked in the LVAD inflow cannula. With LVAD low flow only the increase in motor temperature gave a hint of the thrombosis and a computer tomography scan confirmed the diagnosis. Pump exchange was performed with an uneventful outcome.

Hemodynamic speed ramp tests are used in left ventricular assist device (LVAD) patients to guide speed adjustment and medical therapies. However, the reproducibility of these tests is unknown. In this prospective study, clinically stable LVAD patients underwent echocardiography and right heart catheterization ramp tests followed by a repeat test within 2 years as per institutional protocol. Sixteen patients (61.8 ± 10.5 years old, 50% male, eight with HeartMate II and eight with HVAD) underwent repeated ramp testing...

Left ventricular assist devices (LVADs) are being used widely to support patients with advanced systolic heart failure. Some of these patients will need more than one LVAD replacement due to pump thrombosis. The Heartmate III LVAD (Abbott Inc, Chicago, IL) recently has been shown to have a very low incidence of pump thrombosis. In this article, we describe cases of patients with multiple pump thrombosis events, who were successfully replaced with the Heartmate III.

Infection is a serious complication of left ventricular assist device (LVAD) therapy. However, an optimal antimicrobial surgical infection prophylaxis (SIP) regimen for LVAD implantation is not well established. We retrospectively reviewed all adults who underwent continuous-flow LVAD implantation from February 2007 to March 2015 at Mayo Clinic Rochester. Left ventricular assist device infection (LVADI) was defined using criteria published by the International Society for Heart and Lung Transplant. Patients excluded from the analysis included those who did not have HeartMate II or HeartWare device, patients with incomplete documentation of SIP, and those with an actively treated infection at the time of LVAD implantation...

The incidence of ramp test echocardiogram-associated embolic events in the setting of therapeutic anticoagulation is likely rare and has not been reported. We present such a case in a patient with a HeartMate II left ventricular assist device (LVAD) whose serial head computed tomography images, deteriorating clinical course, and the multiembolic nature of the event suggest causality. If the pretest probability of pump thrombosis in an individual LVAD patient is sufficiently high, the potential risks of performing a ramp study echocardiogram may not be warranted, even in the setting of adequate anticoagulation...
