Dehiscence of Freestyle aortic valve visualized by real-time three-dimensional transoesophageal echocardiography and dual-source computed tomography: A rare cause of aortic regurgitation

摘要

A 54-year-old man was admitted because of acute decompensated heart failure. Ten years ago, he underwent implantation of a 27 mm Freestyle aortic root stentless bioprosthesis (Medtronic Inc., Minneapolis, Minnesota) with a subcoronary technique for severe aortic regurgitation (AR) due to the bicuspid valve, combined with mitral valve repair for moderate mitral regurgitation (MR) due to anterior leaflet prolapse.
