Balloon Expandable Transcatheter Aortic Valve Implantation in Failing Self-Expandable Transcatheter Valve in Degenerated Surgical Bioprosthesis: Valve-in-Valve-in-Valve Implantation for the Treatment of Early Degenerative Prosthetic Insufficiency.

Background: Transcatheter aortic valve implantation (TAVI) has emerged as the standard of care for patients with severe aortic stenosis who are at high surgical risk. However, transcatheter valves can degenerate, and redo TAVI has been reported after surgical aortic valve implantation and post initial TAVI. Case Report: We describe the case of a 70-year-old male who presented with decompensated heart failure secondary to severe prosthetic valve insufficiency. The patient had a history of distant triple coronary artery bypass surgery in 2004, surgical ascending aortic aneurysm repair and stentless aortic valve replacement in 2012, and transcatheter CoreValve (Medtronic) implantation in 2015 for the failing stentless aortic valve. In 2019, the patient presented with heart failure symptoms. A 29-mm SAPIEN 3 valve (Edwards Lifesciences) was implanted for the third time (valve-in-valve-in-valve) with excellent clinical and echocardiographic results and no evidence of coronary obstruction. Conclusion: Early (<5 years) bioprosthetic valve insufficiency after initial valve-in-valve implantation can be successfully treated with a second TAVI.
