Presentation transcript:

Leah M. Wright et al. JIMG 2016;9:733-746 Interpretation of RV Function in the Context of PASP and PVR Right ventricular (RV) function is readily evaluated if pulmonary artery systolic pressure (PASP) is normal or near-normal on treatment, as long as pulmonary vascular resistance (PVR) is not increased. If PASP is elevated, normal RV function is reassuring, but reduction of RV function may simply reflect increased afterload rather than intrinsic RV impairment. In this setting, assessment of RV-PA interaction is required. ESV = end-systolic volume; SV = systolic volume. Leah M. Wright et al. JIMG 2016;9:733-746 American College of Cardiology Foundation
