Because of its rare entity, large data are lacking, and therefore, treatment guidelines are missing.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>We describe a case of a 53-year-old male with a past medical history of ascending aortic aneurysm and severe aortic regurgitation who underwent Bentall procedure with 26\u2005mm conduit and mechanical aortic valve 1 year before. Follow-up chest computed tomography (CT) revealed coronary button dehiscence with a giant aortic root pseudoaneurysm and mural thrombus inside. Given the risk of rupture, the heart team decided to go for a percutaneous approach. Based on a pre-interventional 3D reconstructed CT scan and guided by transoesophageal echocardiography and intravascular ultrasound, the pseudoaneurysm was successfully occluded with a 6 \u00d7 4\u2005mm Amplatzer Duct Occluder II and simultaneous left main coronary artery (LMCA) stenting with a 4.0 \u00d7 15\u2005mm drug-eluting stent. Post-procedural chest CT and echocardiography revealed minimal contrast leakage posterior to the aortic root and para LMCA region, confirmed thrombosis formation post occluder and stent deployment, and patent flow of LMCA.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>We describe the successful
