Congestive heart failure (CHF) is a debilitating condition that afflicts tens of millions of people worldwide and is responsible for more deaths each year than all cancers combined. Because donor hearts for transplantation are in short supply, a safe and durable means of mechanical circulatory support could extend the lives and reduce the suffering of millions. But while the profusion of blood pumps available to clinicians in 2019 tend to work extremely well in the short term (hours to weeks/months), every long-term cardiac assist device on the market today is limited by the same two problems: infections caused by percutaneous drivelines and thrombotic events associated with the use of blood-contacting surfaces. A fundamental change in device design is needed to address both these problems and ultimately make a device that can support the heart indefinitely. Toward that end, several groups are currently developing devices without blood-contacting surfaces and/or extracorporeal power sources with the aim of providing a safe, tether-free means to support the failing heart over extended periods of time.

Introduction: Since the celebration of the 20th anniversary of the first heart transplantation in Hungary in 2012 the emerging need for modern heart failure management via mechanical circulatory support has evolved. In May 2012 the opening of a new heart failure and transplant unit with 9 beds together with the procurement of necessary devices at Semmelweis University accomplished this need. Aim: The aim of the authors was to report their initial experience obtained in this new cardiac assist device program. Method: Since May, 2012, mechanical circulatory support system was applied in 89 cases in 72 patients. Indication for support were end stage heart failure refractory to medical treatment and acute left or right heart failure. Results: Treatment was initiated for acute graft failure after heart transplantation in 27 cases, for end stage heart failure in 24 cases, for acute myocardial infarction in 21 cases, for acute postcardiotomy heart failure in 14 cases, for severe respiratory insufficiency in 2 cases and for drug intoxication in one case. Among the 30 survivor of the whole program 13 patients were successfully transplanted. Conclusions: The available devices can cover all modalities of current bridge therapy from short term support through medium support to heart transplantation or long term support and destination therapy. These conditions made possible the successful start of a new cardiac assist device program. Orv. Hetil., 2015, 156(13), 521–527.

Ventricular Assist

Mechanical circulatory support (MCS) involves the use of intra-aortic balloon pump (IABP), short-term percutaneous ventricular assist devices, long-term surgically implanted continuous-flow ventricular assist devices (cf-LVADs), and extracorporeal membrane oxygenation (ECMO) for the treatment of acute and chronic heart failure and cardiogenic shock. IABP is increasingly recognized as an important adjunct in the postoperative treatment arsenal for those patients with severely reduced left ventricular systolic function. Short-term percutaneous options for the treatment of acute right and left heart failure include both the Impella and Tandem Heart, whereas the Centrimag is often used in the surgical setting for acute cardiogenic shock and heart failure. Long-term surgical MCS options include the total artificial heart and the cf-LVADs HeartWare and Heartmate II. ECMO is frequently used for the treatment of acute cardiogenic shock and may be placed peripherally via a percutaneous approach or with central cannulation. ECMO is also increasingly used in the setting of acute cardiac life support, known as extracorporeal life support. Key words: cardiac critical care, extracorporeal membrane oxygenation, long-term ventricular assist device, mechanical circulatory support, short-term ventricular assist device
