[Acute aortic dissection during ineffective attempt of transcatheter implant of a fully resheathable, respositionable and retrievable aortic valve]. / Dissezione aortica acuta durante tentativo inefficace di impianto transcatetere di protesi aortica totalmente riposizionabile e recuperabile.

ABSTRACT

Aortic injury is a rare but severe complication that may occur during transcatheter aortic valve implantation (TAVI). Few patients with type A dissection are treated surgically because of the high rate of postoperative mortality and neurological complications in this high-risk population; thoracic endovascular aortic repair is rare too, and technically challenging because of the anatomical variations of spiral type A aortic dissection. Sometimes a watchful waiting strategy could be the best solution. We report the case of an acute, extended aortic type A dissection occurred during a TAVI procedure, probably due to the rupture of the dedicated sheath, and conservatively managed.
