This study details a successful percutaneous repair of a paravalvular leak in a mechanical aortic valve prosthesis. The minimally invasive approach utilized a ventricular septal defect closure device, reducing surgical risk for the patient.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Paravalvular leaks (PVLs) are potential complications of prosthetic heart valve replacement.
- Mechanical aortic prostheses can develop paravalvular leaks, necessitating intervention.
- Previous surgery in a patient increases perioperative risks for re-intervention.
