Left ventricular assist devices as long-term mechanical circulatory support are increasingly utilized as an option for medically refractory advanced heart failure. Rapid advances in this field, from pulsatile paracorporeal flow pumps to now more advanced intracorporeal continuous flow devices, have led to more wide spread use of device therapy. Several trials have now confirmed the survival benefits of ventricular assist devices, not only as a method for bridging patients waiting on the transplant list, but also as an evolving paradigm of destination therapy. Significant improvements in quality of life and functional status have been reported in patients receiving these devices. Survival outcomes with this therapy continue to improve, and long term durability of newer generation devices remains yet to be discerned. Comparative data to heart transplantation remains scarce. This paper will focus on the historical development of ventricular assist device therapy for advanced heart failure, review major trials of destination therapy, and look at comparative literature in the modern era to cardiac transplantation.

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. Heart transplantation remains an option for a limited number of patients only, and this fact has also triggered the discussion about the optimal timing for device implantation. The increasing use of continuous-flow devices has resulted in new challenges, such as adverse events during long-term support, and high hospital readmission rates. In addition, there are a number of device-related complications including mechanical problems such as device thrombosis, percutaneous driveline damage, as well as conditions such as hemolysis, infection, and cerebrovascular accidents. This review provides an overview of the evolution of mechanical circulatory support systems from bridge to transplantation to destination therapy including technological advances and clinical improvements in long-term patient survival and quality of life. In addition, recent changes in device implant strategies and current trials are reviewed and discussed. A brief glimpse into the future of mechanical circulatory support therapy will summarize the innovations that may soon enter clinical practice.

The shortage of appropriate donor organs and the expanding pool of patients waiting for heart transplantation have led to growing interest in alternative strategies, particularly in mechanical circulatory support. Improved results and the increased applicability and durability with left ventricular assist devices (LVADs) have enhanced this treatment option available for end-stage heart failure patients. Moreover, outcome with newer pumps have evolved to destination therapy for such patients. Currently, results using nonpulsatile continuous flow pumps document the evolution in outcomes following destination therapy achieved subsequent to the landmark Randomized Evaluation of Mechanical Assistance for the Treatment of Congestive Heart Failure Trial (REMATCH), as well as the outcome of pulsatile designed second-generation LVADs. This review describes the currently available types of LVADs, their clinical use and outcomes, and focuses on the patient selection process.

Background Left ventricular assist devices (LVAD) are an increasingly used therapy for patients with advanced heart failure. Arrhythmias are common complications following LVAD implantation requiring admission, initiation, and escalation of medical therapy. Despite their frequent use in the treatment of arrhythmias, little has been reported regarding electrocardiographic changes, antiarrhythmic utilization, and outcomes post-LVAD. Methods A total of 309 patients who received a LVAD underwent retrospective chart review pre- and post-LVAD. Kaplan-Meier curves were calculated and compared using the log-rank test. Cox regression model was used for univariate analysis and those with a p Results There was a significant reduction in both the QRS interval (p=0.0001) and QTc interval (p=0.0074) following LVAD implantation. Ventricular tachycardia is common following LVAD implant at 31.1%. Amiodarone use was frequent prior to LVAD (52.1%) and on discharge (68.6%). Amiodarone use (p=0.019, HR 1.7, 95% CI 1.1-2.6), age at implant (p Conclusion Amiodarone is a commonly used antiarrhythmic in advanced heart failure and its use prior to LVAD implantation may increase the risk of long-term mortality. Amiodarone's efficacy needs to be weighed against its long-term side effects and implant on clinical outcomes

Advanced heart failure (HF) with persistent and progressive clinical decline despite maximal medical therapy portends a high mortality in the absence of advanced therapies, such as ventricular assist devices or heart transplantation. A subset of these advanced HF patients deteriorates into refractory cardiogenic shock, that is challenging to manage with vasoactive agents alone. Temporary mechanical circulatory support (MCS) device options have evolved over the years and provide a viable option to rescue and rest the myocardium of patients in cardiogenic shock. The goal of such therapy is to serve as bridge to recovery, or more often, a bridge to durable advanced therapies. For those patients with progressive advanced HF despite extensive medical therapy, durable MCS devices (ventricular assist devices) are available when heart transplantation is not feasible. In this article, we review currently available temporary and durable MCS devices, with a focus on their hemodynamic profiles, to inform optimal device selection for patients with advanced HF.

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
