title: Ventricular volume reduction procedures.
abstract: Although partial left ventriculectomy (PLV) has been abandoned in many institutions, a few hospitals continue to perform it with a relatively favorable outcome. Other volume reduction procedures have become popular with renewed interest in ventricular reshaping to improve function. Although recent refined selection criteria have improved survival with PLV, earlier unpredictable results prompted less invasive procedures based on the same physiologic concept of reducing radius or wall tension by wrapping, piercing, or clasping. These new techniques are not only less invasive but also reversible and adjustable and appear safer for less symptomatic patients at risk of progressive heart failure. Nonetheless, mechanisms of action and degrees of volume reduction and/or restriction need to be delineated before widespread clinical application.
