"Valve in valve" implantation of two self-expandable transcatheter aortic valves in a patient with aortic root aneurysm and massive aortic regurgitation: "a new TAVI option".

Catheter-based treatment of aortic regurgitation (AR) often proves challenging especially due to associated anatomical difficulties. Here, we present a case of CoreValve implantation with a novel use of the valve-in-valve technique to effectively treat severe AR in a patient with repeated cardiac surgery and aneurismatic prosthetic ascending aorta.
