Transfemoral aortic valve-in-valve implantation with a balloon-expandable valve for the treatment of stentless xenograft severe aortic regurgitation

摘要

An 80-year-old woman was admitted with pulmonaiy edema. She had a history of 2 prior sternotomies: a coronary artery bypass grafting (CABG) plus aortic valve replacement (AVR) with a 23-mm Medtronic-Freestyle (Minneapolis, Minnesota) stentless biopros-thesis 15 years ago, and a redo CABG 10 years ago. Doppler echocardiography showed severe aortic xeno-graft regurgitation (Figs. 1A and IB, Online Videos 1, 2, and 3). The patient was considered at very high risk for re-AVR (third sternotomy, STS score: 10.7%, logistical EuroSCORE: 26.3%) and was consequently proposed for transcatheter aortic valve implantation (TAVI), therefore, a valve-in-valve procedure.
