A Case of Successful Transcatheter Aortic Valve Replacement Using SENTINEL Cerebral Protection System for Severe Aortic Stenosis with Left Intracardiac Thrombus

抄録

Objective: Cerebral infarction is a serious complication of transcatheter aortic valve replacement (TAVR). We report a case of a symptomatic severe aortic stenosis (AS) patient with thrombi in the left ventricle and atrial appendage who successfully underwent TAVR using the SENTINEL Cerebral Protection System (CPS) (Boston Scientific, Marlborough, MA, USA).

Case Presentation: We performed TAVR with the SENTINEL CPS in a patient with severe AS, who presented with a high risk of cerebral infarction due to thrombi in the left ventricle and atrial appendage. The perioperative and postoperative courses were uneventful and was without cerebral infarction or other complications.

Conclusion: Employment of the SENTINEL CPS during TAVR may be useful in reducing the risk of stroke in patients with a high risk of perioperative stroke, such as a left intracardiac thrombus.
