Percutaneous Circulatory Assist Devices for Right Ventricular Failure.

Heart failure is a major cause of global morbidity and mortality affecting nearly 24 million individuals worldwide. Although the importance of right ventricular (RV) function has become more apparent over the past few decades, few therapies specifically target RV failure. Over the past 3 decades, significant advances in percutaneously delivered circulatory support devices has led to the recent development of devices specifically designed for RV failure. In this review, RV pathophysiology, device options, and clinical data exploring the utility of percutaneous RV support devices are discussed.
