Transthoracic echocardiogram (TTE) revealed a right coronary sinus pseudoaneurysm and a large interventricular septal dissecting aneurysm (DAIS) communicating with the left ventricular outflow tract (LVOT). Cardiac computed tomography angiography (CCTA) delineated the pseudoaneurysm and its relationship to the coronary arteries, and cardiovascular magnetic resonance (CMR) supported septal myocardial involvement. Transesophageal echocardiogram (TEE) further characterized annular disruption and deformation of the right coronary cusp (RCC). The patient subsequently underwent bovine pericardial patch repair and aortic valve replacement. At the 3-month postoperative follow-up, recovery was favorable, with a left ventricular ejection fraction (LVEF) of 55%; however, pseudoaneurysm recurrence was detected at 6\u202fmonths. The patient declined reoperation and died 8\u202fmonths after the initial surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>We report an exceptionally rare adult case of aortic annular avulsion with a right coronary sinus pseudoaneurysm and aorto\u2013left ventricular communication.
