Characterization of Right Ventricular Remodeling in Pulmonary Hypertension Associated With Patient Outcomes by 3-Dimensional Wall Motion Tracking Echocardiography

112 subjects: 92 patients with pulmonary hypertension (PH) and 20 normal controls.

3-dimensional (3D) wall motion tracking echocardiography to assess right ventricular (RV) end-systolic volume index (ESVi), RV ejection fraction (EF), and RV global area strain, along with invasive hemodynamic measurements.

Normal controls and comparison across RV remodeling classifications (RV adapted, RV adapted-remodeled, RV adverse-remodeled).

Combined end point of PH-related hospitalization, death, or lung surgery (lung transplantation or pulmonary endarterectomy) during 6 months.composite
