Acute Effects of Left Ventricular Support With Impella 5.5 on Biventricular Hemodynamics

Circulation: Heart Failure, Ahead of Print.
Identification of patients with cardiogenic shock and right ventricle (RV) dysfunction who may require biventricular rather than isolated left ventricular (LV) support remains challenging. In this setting, rigorous hemodynamic evaluation of biventricular contractility and load during initiation of LV support guides therapy. We now report a novel approach to assess biventricular pressure-volume loops in a patient receiving Impella 5.5 support for heart failure and shock.
