BACKGROUND AND PURPOSE: Short-term ventricular assist device (VAD) support is used in the intensive care unit (ICU) to support individuals in end-stage heart failure prior to heart transplantation or implantation of a long-term left VAD. The literature investigating the feasibility, safety, and content of rehabilitation for this patient group is lacking. This report retrospectively describes the rehabilitation strategy, safety measures used, and nature of any adverse events and, therefore, the feasibility of this practice...

The CentriMag, an extracorporeal short-term ventricular assist device designed for treatment of patients with acute cardiogenic shock, is Conformité Européenne-marked in Europe for use up to 30 days. Extended use beyond the licensed period is not uncommon, however. We have developed a skirted cannula technique for apical cannulation in implantation of the Centrimag. This technique allows easy positioning of the cannula and excellent hemostasis. It also offers secure fixation of the cannula so that patients can ambulate and attend rehabilitation programs should extended use be anticipated...

With more than 60 years of continuous development and improvement, a variety of temporary mechanical circulatory support (MCS) devices and implantation strategies exist, each with unique advantages and disadvantages. A thorough understanding of each available device is essential for optimizing patient outcomes in a fiscally responsible manner. In this state of the art review we examine the entire range of commonly available peripheral and centrally cannulated temporary MCS devices, including intra-aortic balloon pumps, the Impella (Abiomed, Danvers, MA) family of microaxial pumps, the TandemHeart (CardiacAssist Inc, Pittsburg, PA) pump and percutaneous cannulas, centrally cannulated centrifugal pumps such as the CentriMag (Thoratec Corp, Pleasanton, CA/St Jude Medical, St Paul, MN/Abbott Laboratories, Abbott Park, IL) and Rotaflow (Maquet Holding BV & Co KG, Rastatt Germany), and extracorporeal membrane oxygenation...

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...

UNLABELLED: A 61-year-old male presented to our emergency room with chest tightness, dyspnea, and cold sweat. He underwent a 12-lead EKG which showed ST-elevation from leads V1-V4 and T wave inversion in leads II, III, and aVF. His troponin-I level was elevated to 70.3 ng/ml. He went into cardiogenic shock when he was in the catheter room. After advanced cardiac life support was administered for 30 min, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) cannulation was set up using 21-french arterial and 21-french venous cannula through the right femoral artery and right femoral vein by the puncture method for hemodynamic support...

BACKGROUND: The therapeutic options for heart failure include inotropic agents, intraaortic balloon pumps, and left ventricular assist devices (LVAD). Implantable LVADs are not appropriate for all patients. The short-term devices require patients to stay in bed, connected to cannulas, which are usually inserted using a median sternotomy. This approach requires a subsequent sternotomy, midline cannulas (which can make sitting difficult), and immobility. We began using a right thoracotomy with cannulas placed through intercostal spaces for selected patients in need of temporary LVAD support...

The Levitronix CentriMag is approved in Europe for 30 days as uni- or biventricular support in acute heart failure as a bridge to recovery, bridge to heart transplantation or to a long-term left ventricular assist device (LVAD). We report the case of a patient who was supported with the same Levitronix CentriMag pump for 119 days without changing any components of the circuit or the pump head because of an anatomical condition which precluded the feasibility of pump exchange and who did not experience any mechanical failure of the impeller but eventually died due to the rupture of the cannulae...

The left ventricular assist device may be a lifesaving therapy for a patient awaiting a heart transplant. The most common complications of this device are mediastinal bleeding, infections, embolic events, right-sided heart failure, and mediastinal adhesions. We are reporting a patient who had a Levitronix left ventricular assist device implanted with mini-pericardiotomy technique for bridging to heart transplant.

Fulminant myocarditis (FM) represents a crucial cardiac pathology with extensive hemodynamic compromise occurring in a previously healthy patient. Early death occurs because of acute cardiac decompensation from inflammation, necrosis, and myocytolysis. Nevertheless, in this situation implantation of an extracorporeal circulatory support system may ensure cardiac recovery. We herein report our experience using a biventricular Levitronix CentriMag system for bridge to recovery.

BACKGROUND: The use of short-term ventricular assist devices (VAD) in patients awaiting high-urgency (HU) heart transplantation (HTx) in Spain has steadily increased due to longer waiting times and the new heart allocation system. It is unknown whether the use of short-term VAD support in patients with cardiogenic shock affects HTx outcome. We sought to investigate long-term outcomes of HU transplanted patients with VAD compared with HU transplanted patients without device support. METHODS: We retrospectively evaluated all HTx patients transplanted between 1999 and 2011 in our institution...

Ventricular assist device (VAD) therapy has been used successfully as a bridge to recovery, bridge to transplant and in the last decade as a destination therapy. The use of VAD for post-cardiotomy cardiogenic shock (PCCS) is not currently reported in national databases in the UK and Ireland. Data were collected through a telephone survey of chief perfusionists from all the cardiac surgery units in the UK and Ireland between October 2007 and October 2008. Approximately 28 000 adult cardiac surgical procedures were performed at 45 cardiac centres, of which 33 (73%) reported using VAD...
