A 56-year-old woman presented with a 1-year history of progressive dyspnoea on exertion. Echocardiography and right heart catheterization demonstrated severe right ventricular enlargement and pulmonary hypertension (74/40 mmHg) without any evidence of atrial septal defect (ASD). Cardiac magnetic resonance (CMR) imaging was performed to identify possible causes. Cine MR showed severe right ventricular enlargement right ventricular end-diastolic volume index (RVEDVI) (160 mL/m2) with moderate systolic dysfunction right ventricular ejection fraction (RVEF) (35%) ( Panel …
