Abstract

A woman with a single coronary artery underwent aortic valve replacement due to aortic stenosis. Two years later, she developed an aortic annular abscess around the right coronary cusp and non-coronary cusp. Significant adhesions to the right coronary artery (RCA) resulted from the abscess, making artery separation challenging, and raising concerns about potential future RCA stenosis. The patient subsequently underwent aortic root replacement and coronary artery bypass grafting. Utilizing a freestyle valve and a saphenous vein graft for the RCA. Following the procedure, the patient was discharged and has remained symptom-free without any recurrence of infection for 2 years.

摘要

一名患有单支冠状动脉的女性因主动脉瓣狭窄接受了主动脉瓣置换术。两年后，她在右冠状动脉瓣叶和无冠状动脉瓣叶周围出现了主动脉瓣环脓肿。脓肿导致与右冠状动脉（RCA）形成严重粘连，使动脉分离具有挑战性，并引发了对未来RCA狭窄可能性的担忧。该患者随后接受了主动脉根部置换和冠状动脉搭桥术。使用自由型瓣膜和大隐静脉移植物来处理RCA。手术后，患者出院，并且在两年内一直无症状，没有任何感染复发。
