Closure of an ascending aorta perforation during a transseptal puncture procedure: transcatheter closure with a muscular ventricular septal defect occluder.

Abstract

Background: Ascending aortic perforation is a rare complication of the transseptal puncture procedure that often requires emergency management.

Case presentation: We report the case of a 53-year-old woman with severe mitral stenosis (MS) who underwent percutaneous balloon mitral valvuloplasty (PBMV). After the transseptal puncture procedure, a right atrium-iatrogenic ascending aortic perforation was observed. An 8-mm muscular ventricular septal defect (VSD) occluder was then successfully used for emergency closure.

Conclusion: Percutaneous closure of ascending aortic perforations via a muscular VSD occluder is a feasible treatment approach.
