The benefits and disadvantages of pulsatility in mechanical circulatory support devices have been argued since before the first use of cardiopulmonary bypass (CPB) with a nonpulsatile pump. The debate over the superiority of either pulsatile or nonpulsatile perfusion during CPB persists, but recently, the evidence in favor of pulsatile perfusion during CPB is increasing. Complications associated with chronic nonpulsatile flow in patients implanted with left ventricular assist devices have renewed interest in generating pulsatility with these devices...

Transplant center expertise improves survival after heart transplant (HTx) but it is unknown whether center expertise ameliorates risk associated with mechanical circulatory support (MCS) bridge to transplantation. This study investigated whether center HTx volume reduced survival disparities among pediatric HTx patients bridged with extracorporeal membrane oxygenation (ECMO), left ventricular assist device (LVAD), or no MCS. Patients ≤18 years of age receiving first-time HTx between 2005 and 2015 were identified in the United Network of Organ Sharing registry...

Mechanical circulatory support has revolutionized the treatment of heart failure, affording patients significantly improved survival and quality of life. However, further advancements in this technology have been hindered by adverse events, particularly gastrointestinal bleeding, driveline infection, stroke, and device thrombosis. Recently, there has been a renewed focus on device thrombosis as the reported incidence has increased. This review focuses on an update on the diagnostic modalities and current treatment algorithms of this serious complication...

The abnormal structure, function and molecular makeup of dilated cardiomyopathic hearts can be partially normalized in patients supported by a left ventricular assist device (LVAD), a process called reverse remodeling. This leads to recovery of function in many patients, though the rate of full recovery is low and in many cases is temporary, leading to the concept of heart failure remission, rather than recovery. Areas covered: We summarize data indicative of ventricular reverse remodeling, recovery and remission during LVAD support...

Left ventricular assist device (LVAD) implantation is a well-established therapy to support patients with end-stage heart failure. However, the operative procedure is associated with severe trauma. Third generation LVADs like the HeartWare assist device (HeartWare, Inc., Framingham, MA, USA) are characterized by enhanced technology despite smaller size. These devices offer new minimally invasive surgical options. Tricuspid regurgitation requiring valve repair is frequent in patients with the need for mechanical circulatory support as it is strongly associated with ischemic and nonischemic cardiomyopathy...

The use of mechanical circulatory support (MCS) devices is a viable therapeutic treatment option for patients with congestive heart failure. Ventricular assist devices, cavopulmonary assist devices, and total artificial heart pumps continue to gain acceptance as viable treatment strategies for both adults and pediatric patients as bridge-to-transplant, bridge-to-recovery, and longer-term circulatory support alternatives. We present a review of the current and future MCS devices for patients having congenital heart disease (CHD) with biventricular or univentricular circulations...

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...

Although some patients with fulminant myocarditis can be rescued owing to the improvements in mechanical circulatory support therapy, there are few reports providing evidence of cardiac rehabilitation during mechanical circulatory supports, particularly among pediatric patients. We treated two pediatric patients who underwent aggressive cardiac rehabilitation during mechanical support. Five days after the initiation of extracorporeal membrane oxygenation therapy aggressive cardiac rehabilitation was started in a 10-year-old girl with fulminant myocarditis...

Because the first generation of pulsatile-flow devices was primarily used to bridge the sickest patients to transplantation (bridge-to-transplant therapy), the current generation of continuous-flow ventricular assist devices qualifies for destination therapy for patients with advanced heart failure who are ineligible for transplantation. The first-generation devices were associated with frequent adverse events, limited mechanical durability, and patient discomfort due device size. In contrast, second-generation continuous-flow devices are smaller, more quiet, and durable, thus resulting in less complications and significantly improved survival rates...

BACKGROUND: Refractory post-cardiotomy cardiogenic shock (PCCS) is a relatively rare phenomenon that can lead to rapid multi-organ dysfunction syndrome and is almost invariably fatal without advanced mechanical circulatory support (AMCS), namely extra-corporeal membrane oxygenation (ECMO) or ventricular assist devices (VAD). In this multicentre observational study we retrospectively analyzed the outcomes of salvage venoarterial ECMO (VA ECMO) and VAD for refractory PCCS in the 3 adult cardiothoracic surgery centres in Scotland over a 20-year period...

OBJECTIVES: The use of short-term mechanical circulatory support (MCS) has increased in the treatment of refractory cardiogenic shock (RCS). Percutaneous short-term MCS technology has emerged rapidly; however, limitations in flow and durability remain. We therefore investigated a minimally invasive surgical approach using an external ventricular assist device (VAD) and extracorporeal membrane oxygenation (ECMO) in patients with RCS. METHODS: Twenty-five patients underwent minimally invasive external VAD insertion with a magnetically levitated centrifugal pump for various causes of cardiogenic shock between April 2010 and May 2016...

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...

BACKGROUND: Despite advances in treatment, mortality in acute myocardial infarction complicated by cardiogenic shock remains high. Short-term mechanical circulatory support devices acutely improve hemodynamic conditions. The Impella CP is a new percutaneous circulatory support device that provides more hemodynamic support than the intra-aortic balloon pump (IABP). OBJECTIVES: The aim of this study was to determine whether the Impella CP can decrease 30-day mortality when compared with IABP in patients with severe shock complicating acute myocardial infarction...

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%)...

INTRODUCTION: Mechanical circulatory support (MCS) therapy is associated with the improvement of long-term prognosis in patients with end-stage heart failure. For years it has been used as a bridge to transplant. However, more recently it is even being used as a destination therapy. Recently, clinicians have identified common MCS therapy-associated complications: pump thrombosis, bleeding, and hemolysis. These complications are very challenging with regard to both diagnosis and management...
