New generation devices for long-term mechanical circulatory support are centrifugal pumps having fully magnetically levitated rotors to reduce blood trauma. Recently, the novel HeartMate 3 was cleared for clinical application in Switzerland. In two Swiss University Hospitals part of the "Lausanne-Geneva Transplantation Network," 10 consecutive patients in end-stage heart failure received the HeartMate 3. Device implantation criteria were persistent low output syndrome despite optimal medical treatment. The primary end-point of the study was survival or transplantation to 90 days on the device...

Frailty and heart failure share common pathways with symptoms that often coexist. Assessment of frailty may inform patient selection for left ventricular assist device (LVAD) therapy. Using Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) data of destination therapy (DT) LVAD patients from January 1, 2012, to March 31, 2014, we examined preimplantation provider-assessed frailty and gait speed testing and the association with 1 year postimplantation outcomes. Of 2,469 patients, 227 (9...

The model for end-stage liver disease (MELD) has been used as a predictor of mortality after left ventricular assist device (LVAD) placement. However, improvement or worsening of MELD and how those changes affect outcomes is unknown. We performed a retrospective analysis of 244 patients implanted with a continuous flow (CF) LVAD. Patients were dichotomized at admission into low- or high-risk categories using a cutoff of MELD ≥ 19, and they were reclassified at day of implant forming four groups: Group LL (remained low risk), LH (worsened to high risk), HH (remained high risk), and HL (improved to low risk)...

OBJECTIVES: The Berlin Heart EXCOR ® (EXCOR) paediatric ventricular assist device is used worldwide for mechanical support of infants and small children with end-stage heart failure. A clinically important gap between the smallest EXCOR blood pump (10 ml) and the next larger size (25 ml) limited the choice of pump size in patients with a body surface area (BSA) between 0.33 and 0.5 m 2 . We present the first clinical experience from the early product surveillance (EPS) of the new EXCOR 15-ml blood pump...

Left ventricular assist device (LVAD) therapy unloads the failing heart but exposes the human body to unique pathophysiologic demands such as continuous blood flow and complete univentricular support, which are associated with increased risk of adverse clinical outcomes. MicroRNAs (miRNAs) are 22-23 nucleotide RNAs involved in regulation of multiple biologic processes including the pathogenesis of heart failure (HF). Thus, measurement of miRNAs may have potential in both diagnostics as circulating biomarkers and in therapeutics for targeted interventions...

BACKGROUND: The use of left ventricular assist devices (LVADs) has gained significant importance for treatment of end-stage heart failure. Fast-track procedures are well established in cardiac surgery, whereas knowledge of their benefits after LVAD implantation is sparse. We hypothesized that ultra-fast-track anesthesia (UFTA) with in-theater extubation or at a maximum of 4 h. after surgery is feasible in Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) level 3 and 4 patients and might prevent postoperative complications...

In Japan the 1st paracorporeal ventricular assist device (VAD) was implanted in 1980. Since then, more than 2,000 VADs were used. Small size continuous-flow VAD (CFVAD) was developed in 1990s, which dramatically improved safety and efficacy of long-term support. EVAHEART and DuraHeart, both of which were developed in Japan, were approved for health insurance coverage in 2011, followed by approval of HeartMate II in 2013 and Jarvik 2000 in 2014. Although these approvals were limited for bridge to transplantation, CFVADs gained rapid acceptance for treatment of end-stage heart failure...

Mechanical circulatory support improves survival and quality of life in selected patients with advanced heart failure. The Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) clinical profile (profiles 1-7) is a classification system of patients with American Heart Association stage D and New York Heart Association functional class IIIb-IV heart failure. Most left ventricular assist devices (LVADs) are implanted in patients dependent on inotropes (INTERMACS 3) or whose condition is deteriorating with inotropic support (INTERMACS 2)...

REVIEW
Alain Combes
Mechanical circulatory assistance has become a frequent therapeutic option for patients with advanced heart failure. For patients with acute cardiogenic shock and impaired organ function, short-term assistance with venoarterial extracorporeal membrane oxygenation is the leading therapeutic option. It enables a "bridge to decision-making" i.e. withdrawal of the device after myocardial recovery or after recognition of therapeutic futility, or as a bridge-to-transplantation or to long-term mechanical support. For Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) class 2-6 patients, implantation of a long-term ventricular assist-device (VAD) should be considered before progression to multiple organ failure if heart transplantation is not a first-line option...

Right ventricular failure (RVF) may still occur despite the benefits of minimally-invasive left ventricular assist device (MI-LVAD) implantation. Our center strategy aims to avoid aggressive postoperative inotrope use by utilizing mechanical support to facilitate RV recovery and adaptation. We herein report first outcomes of patients with minimally-invasive temporary right ventricular assist device (MI-t-RVAD) support for RVF during MI-LVAD implantation.RVF was defined as requiring more than moderate inotopic support after weaning from cardiopulmonary bypass according to INTERMACS adverse event definitions...
