title: Peri-aortic hematoma complicated with aortic regurgitation following transcatheter aortic valve implantation: description of a novel mechanism of paravalvular leak.
abstract: The recent development of transcatheter aortic valve implantation (TAVI) for patients with severe aortic stenosis (AS) offers a feasible option for high-risk surgical patients. However, several complications are specifically related to this technique. The present case describes a novel complication associated with TAVI, a severe paravalvular leak related to "stretch-induced" peri-aortic hematoma. The possible mechanisms of this complication, as well as its potential solutions, are discussed.
