Redo in aortic homograft replacement: transcatheter aortic valve as a valid alternative to surgical replacement.

摘要

Reintervention in patients who have undergone an aortic homograft valve replacement remains a technical challenge. We report the case of a patient with multiple aortic valve replacements having an aortic homograft with severe calcific stenosis who successfully underwent transcatheter aortic valve insertion (TAVI). A 48-year-old woman was referred to our hospital with symptoms of ingravescent severe dyspnea. Fifteen years earlier, she had undergone placement of a 21-mm aortic valve Bravo 400 stentless xenograft (Cryolife International, Atlanta, Ga). Four years later, she underwent a valve replacement with a 21-mm mechanical prosthesis (Carbomedics, Austin, Tex) for valve degeneration, and subsequently, she received a homograft for aortic valve endocarditis.
