A case of progressive dyspnea: Atrial septal device-related functional mitral regurgitation after myocardial infarction

Abstract

Transcatheter device closure is a common treatment option of atrial septal defect. Mitral regurgitation has been reported with comorbid mitral valve prolapse and atrial septal defect. However there is no consensus regarding the pathogenesis of mitral regurgitation after closure. We are reporting a patient with functional mitral regurgitation associated with both an oversize closure device and wall motion abnormality after inferior myocardial infarction.
