Figure 5. Changes in the right ventricular pressure-volume loop contour in patients with vs. without pulmonary hypertension.

Figure 5.

Characteristic triangular (Panel A), quadratic (Panel B), trapezoid (Panel C), and notched (Panel D) RV PV loop morphologies, which are associated with varying differentials between pulmonary artery (PA) beginning systolic pressure (BSP) and end-systolic pressure (ESP). Adapted from Richter MJ, et al. Right ventricular pressure-volume loop shape and systolic pressure change in pulmonary hypertension. Am J Physiol Lung Cell Mol Physiol 2021;320(5):L715-l725.26
