Clinical study of right ventricular longitudinal strain for assessing right ventricular dysfunction and hemodynamics in pulmonary hypertension

This study aimed to appraise the application of right ventricular longitudinal strain for assessing right ventricular dysfunction and severe hemodynamic changes in pulmonary hypertension. The study included 53 patients clinically diagnosed with PH. Tissue Doppler–derived tricuspid lateral annular systolic velocity (s’), early diastolic peak velocity (e’), late diastolic peak velocity (a’), tricuspid annular plane systolic excursion (TAPSE), RV...
