title: Percutaneous paravalvular leak closure after CoreValve transcatheter aortic valve implantation using an arterio-arterial loop.
abstract: Significant periprosthetic aortic regurgitation after transcatheter aortic valve implantation has become a major concern of this technique given its association with impaired survival. We report the successful closure of such defect using a vascular occlusion device with the creation of an arterio-arterial loop to gain enough support to advance the delivery sheath into de the left ventricle.
