ABSTRACT

We report the case of a man in his mid 70s with a history of coronary artery bypass grafting and prior surgical repair of an ascending aortic pseudoaneurysm using a bovine pericardial patch. He was subsequently found to have a persistent pseudoaneurysm adjacent to the right coronary ostium. In view of his prior sternotomy and the close proximity of the lesion to the coronary ostium, a transcatheter approach was selected. The pseudoaneurysm was successfully excluded using a duct occluder device, followed by deployment of a covered Papyrus coronary stent to reinforce the neck seal while preserving coronary flow. This case underscores the importance of multimodality imaging for diagnosis and procedural planning in complex, high-risk patients and demonstrates the feasibility of a dual-device transcatheter strategy for managing persistent aortic pseudoaneurysms in anatomically challenging locations.
