Transcatheter closure of an ascending aortic pseudoaneurysm using an atrial septal defect occluder: a case report

This case demonstrates that transcatheter closure of ascending aortic pseudoaneurysms is a viable and safe alternative to surgical repair in selected high-risk patients. The successful use of an atrial septal defect occluder above a sutureless aortic valve prosthesis highlights the adaptability of percutaneous closure devices and the importance of individualized procedural planning. This approach may expand treatment options for patients otherwise considered inoperable.
