Right Ventricular Strain in Pulmonary Arterial Hypertension: A 2D Echocardiography and Cardiac Magnetic Resonance Study

Abstract

RV longitudinal strain by 2DE provides a good alternative for CMR-derived RVEF in patients with PAH. The moderate agreement in strain measurements between 2DE and CMR suggests that further software improvements are needed before these measurements can be used interchangeably in clinical practice.
