Recommendations for the Use of Mechanical Circulatory Support: Device Strategies and Patient Selection

Abstract

T he era of mechanical circulatory support (MCS) began in 1953 with the development of cardiopulmonary bypass to facilitate open heart surgery. This led to requests for Proposals issued in 1977 and 1980, which laid the foundation for the development of implantable MCS for long-term use, including devices capable of hospital discharge, in the 1990s. Although heart transplantation is now commonplace at many hospitals, the inadequate supply of donor hearts and patient contraindications to transplantation continue to severely restrict its application. As the demand for long-term replacement of diseased hearts increases, there is a clear need for innovative, safe, and durable MCS to treat the growing population of patients with advanced heart failure (HF). Many exciting changes in the field of MCS have occurred in the past few years, including the development of smaller portable pumps and the concept of destination therapy (DT), or permanent pump placement as an alternative to heart transplantation. Currently, there are no published guidelines for the use of MCS. Thus, it is our intent that this statement will provide the contemporary cardiologist and other HF providers with an understanding of general considerations when determining the appropriateness of MCS.
