Key result
Aortic disc-deployment technique successfully closes post-TAVI VSD without bioprosthetic valve injury.
Why the study?
Ventricular septal defect is a rare complication of transfemoral TAVI with unclear aetiological factors in some cases, requiring novel treatment approaches.
Case Report (n=1)
This case demonstrates a novel technique for closing a post-TAVI VSD by opening the closure device in the ascending aorta to avoid damaging the bioprosthesis.
May warrant vigilance for atypical VSD post-TAVI; leaves open whether the novel closure technique merits prospective evaluation.
Ventricular septal defect (VSD) is a rare complication of transcatheter aortic valve implantation (TAVI) via the transfemoral approach. Aetiological factors leading to VSD have been reported as post-balloon dilatation, oversized prosthesis implantation, and severe calcification of the aorta. However, we present a case of VSD occurring after TAVI with an Edwards Sapien XT prosthesis without any distinct aetiological factors. We used a new technique for closure of the significant VSD; opening the left ventricular disc of the closure device in the ascending aorta and successfully implanting the device without any damage to the bioprosthetic valve.

Dursun et al. (2015) conducted a case report in Ventricular septal defect after TAVI (n=1). VSD closure by opening the left ventricular disc of the closure device in the ascending aorta was evaluated on Successful occlusion of VSD without damage to the bioprosthetic valve. A significant ventricular septal defect occurring after TAVI was successfully closed using a new technique of opening the left ventricular disc of the closure device in the ascending aorta.
