Looking Back, Going Forward: Understanding Cardiac Pathophysiology from Pressure–Volume Loops

Abstract

Knowing cardiac physiology is essential for health care professionals working in the cardiovascular field. Pressure–volume loops (PVLs) offer a unique understanding of the myocardial working and have become pivotal in complex pathophysiological scenarios, such as profound cardiogenic shock or when mechanical circulatory supports are implemented. This review provides a comprehensive summary of the left and right ventricle physiology, based on the PVL interpretation.
