This review summarizes the historical development, completed clinical trials, and future directions of cardiac resynchronization therapy for heart failure patients.
PURPOSE OF REVIEW: Heart failure is a major public health problem. Many heart failure patients have electrical and mechanical ventricular dyssynchrony, which are risk factors for death in heart failure patients. RECENT FINDINGS: Cardiac resynchronization therapy, by stimulating both ventricles, is a strategy to improve ventricular dyssynchrony. SUMMARY: This paper describes the historic development of this therapy; reviews the results of completed clinical cardiac resynchronization therapy studies, and discusses ongoing and future studies.
