LAA closure device embolization occurs mainly in the periprocedural period but late embolizations are not uncommon. Although embolization into the aorta or the left atrium can be successfully managed by percutaneous techniques in most cases, device embolization into the LV is associated with a higher rate of surgical retrieval, increasing thereby procedure-related morbidity.
Transcatheter aortic valve implantation (TAVI) has become an established technique for the treatment of aortic stenosis in patients who cannot undergo surgery. Although TAVI is obviously less invasive than open surgical repair, it is not free of complications. We report a case of unexplained refractory shock during transfemoral TAVI with subsequent autopsy demonstrating a 1-cm large perforation of the descending thoracic aorta as the cause of death. To the best of our knowledge, this is the first case ever reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
