Fate of mitral regurgitation after transcatheter closure of patent ductus arteriosus: single centre study

A hemodynamically significant patent ductus arteriosus (PDA) may be associated with mitral regurgitation (MR). Available treatment strategies are - surgical PDA ligation ± mitral valve surgery and initial transcatheter PDA closure (PDA-DC) with treatment of MR subsequently, if necessary. We aimed to describe the fate of MR after PDA-DC in patients with PDA and significant MR. On retrospective review of electronic health records between 2013 and 2023, 14 eligible patients were identified. Amongst them, PDA-DC resulted in symptomatic improvement in all. A reduction in the severity of MR was noted in 12 patients (85.7 %).
