Retinal embolic events: frequency and impact following transcatheter aortic valve implantation (TAVI) for aortic stenosis.

Objectives: Transcatheter aortic valve implantation (TAVI) is an established treatment for patients with severe symptomatic aortic stenosis. It has a cerebrovascular accident rate of about 5% but the effect on retinal embolic events has not been previously reported. This study investigated the occurrence of retinal emboli following TAVI.
