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. Methods and analysis In this prospective observational study, 20 patients underwent full ophthalmic examination to assess retinal embolic events prior to TAVI and at 48 hours and 1 month post-TAVI. Results At 48 hours post-TAVI, one patient had a new cotton wool spot in the right eye. At 1 month, another two patients had new retinal emboli events in at least one eye and a fourth patient developed retinal splinter haemorrhages in the right eye. Conclusion Retinal embolic events and new retinal abnormalities following TAVI occurred in 15% and 20% of our cohort, respectively, without any associated retinal damage or significant visual problems. Retinal evaluation may be a useful surrogate test for cerebral embolisation in future studies assessing the utility of new valve prostheses and embolic protection devices
