Lambl's excrescence in transcatheter aortic valve implantation: prevalence and risk of embolic events.

Background: The role of aortic valve Lambl's excrescence (LEs) in determining ischemic events has not been well clarified, but they can represent a potential embolic source during procedures with catheter/device manipulation through the aortic valve. Aim of our study was to assess the prevalence of LEs and the rate of embolism in patients with aortic valve stenosis scheduled for transcatheter aortic valve implantation (TAVI).

Methods: Our population was divided into two groups, named LEs and no-LEs.
