Abstract
An 83-year-old woman was admitted to our centre for symptomatic mitral regurgitation caused by P2 prolapse. On preprocedural echocardiography, the left ventricular ejection fraction was 68%, and neither right ventricular dysfunction nor pulmonary hypertension was detected (Fig. 1A-C; Videos 1 and 2 , view videos online). Although a significant lesion was found in the left anterior descending (LAD) artery on coronary angiography (Supplemental Fig. 1), no significant lesion was found in the right coronary artery (RCA) (Video 3 , view video online).
