Why the study?
TAVI carries an inherent risk of causing cerebral infarctions, primarily from aortic wall and valve embolisms, highlighting the need to understand atheroma dispersal.
Highlights embolic stroke risk in TAVI with aortic atheroma; hypothesis-generating for cerebral protection devices in high-risk patients.
Transcatheter aortic valve implantation (TAVI) is a rapidly evolving treatment option with an inherent risk of causing cerebral infarctions. The mechanism of cerebral infarction during TAVI mainly involves embolisms from the aortic wall and valve. Transoesophageal echocardiography (TEE) is useful for detecting aortic atheromas. We present the case of a patient in whom the dispersal of aortic atheromas was monitored by TEE during TAVI. This report demonstrates the importance of preoperatively predicting embolisms from aortic atheromas in patients with severe aortic stenosis.
