Delayed coronary obstruction leading to death following balloon dilation in self-expanding aortic valve for acute coronary occlusion: a case report

Guidewires for chronic total occlusion may be necessary for patients with severely calcified and stenotic aortic valves that are challenging to navigate. Before undertaking TAVR, precise preoperative evaluation, including accurate risk assessment, multimodal imaging, and thorough planning, is essential. While balloon dilation can provide temporary relief for coronary obstruction, it carries the risk of subsequent delayed coronary occlusion with serious consequences. Chest pain experienced under local anesthesia more directly suggests coronary occlusion.
