Abstract:
In this review of right ventricular (RV) preload, we discuss RV physiology, assessment of RV preload, and optimization of RV preload in the setting of acute RV failure. Early recognition and ongoing reassessment of invasive or noninvasive hemodynamics are critical to the management of acute RV failure. Central venous pressure (CVP) estimates RV preload but should not be the sole parameter guiding management. A comprehensive approach that integrates multiple hemodynamic indices should be considered to guide the resuscitative process in acute RV failure.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
