ReviewSymptomatic relief: left ventricular assist devices versus resynchronization therapy.
In patients who have end-stage heart failure, medical therapy is of limited use, and heart transplantation is frequently not an option because of the shortage of donor hearts. Two new treatment options, left ventricular assist devices (LVADs) and implantable cardiac resynchronization therapy (CRT) devices, can improve survival and quality of life in patients who have heart failure. Both types of devices are easy to implant. ⋯ Therefore, methods must be devised to identify patients who have heart failure who are likely to benefit from these devices. Data suggest that early LVAD implantation, before end-stage heart failure develops, is critical to slowing or reversing disease progression. Similarly, in indicated patients who have less advanced disease, CRT may be particularly beneficial.

Destination therapy: does progress depend on left ventricular assist device development?
The role of therapy using mechanical circulatory support devices has evolved rapidly over the last two decades. New developments in the field achieved smaller adverse events, but, currently, only minor improvements in survival were observed in published observational data. The authors discuss the development of mechanical circulatory support devices as a "destination therapy" option for patients who have end-stage heart failure and are ineligible for heart transplantation as it relates to left ventricular assist device development.
