Post-Bentall Ascending Aortic Pseudoaneurysm Due to Coronary Button Dehiscence.

Ascending aortic pseudoaneurysms after the Bentall procedure caused by proximal or distal anastomotic or coronary dehiscence could carry high operative risks. One report in literature has described transcatheter management for distal anastomotic dehiscence using a vascular plug. A similar management of proximal anastomotic or coronary dehiscence may affect valve function and coronary flows. A successful nonsurgical closure of a left coronary dehiscence aided by multimodal imaging and its short-term follow-up is described.
