Fig. 2From: Right ventricular stiffness constant as a predictor of postoperative hemodynamics in patients with hypoplastic right ventricle: a theoretical analysisRight ventricular pressure–volume loops (PV loop) after one and a half ventricle repair. With the increase in the right ventricular stiffness constant, the PV loop became smaller. The horizontal axis is the instantaneous right ventricular volume (ml) and the longitudinal axis is the instantaneous right ventricular pressure (mmHg)Back to article page
