Percutaneous closure of an iatrogenic ventricular septal defect following mechanical aortic valve replacement using the transseptal technique.

Iatrogenic ventricular septal defects (VSDs) following aortic valve replacement are relatively uncommon and are challenging to close percutaneously given their typical proximity to the prosthetic valve. We describe the successful percutaneous closure of an iatrogenic VSD in a patient with a recent mechanical AVR using the transseptal approach.
