Descending aortic dissection injured by tip of the sheath during transcatheter aortic valve implantation.

An 86-year-old woman was referred for transcatheter aortic valve implantation (TAVI) because of recurrent severe aortic stenosis after balloon aortic valvuloplasty in May 2014. We planned to implant a 23-mm Sapien XT valve by transfemoral approach. During procedure, aortic dissection was detected by transesophageal echocardiography (TEE). The dissection limited to the descending aorta and did not include the ascending aorta. Therefore, our team decided to implant the 23-mm Sapien valve as planned. After the procedure, the dissection was treated conservatively without surgical repair. Three weeks later, she was discharged without any complications.
