Fig. 2

Continuous right ventricular (RV) pressure monitoring showing different stages of right ventricular dysfunction. This figure shows the simultaneous monitoring and overlap of RV and pulmonary artery (PA) pressure waveforms. The normal RV diastolic pressure slope is horizontal due to its high compliance (A). This slope will change from horizontal to oblique slope during RV dysfunction (B). The slope will further develop into a square root shape during RV failure (C). With severe RV failure, the RV systolic upstroke delays, and RV pulse pressure decreases (D). Adopted from Denault et al. (Avendi et al. 2017) with permission
