Unruptured Aneurysm of the Left Sinus of Valsalva Causing Coronary Insufficiency

Aneurysm of the left sinus of Valsalva is extremely rare. Compression of the left coronary artery by such an aneurysm is an unusual complication of this condition and can cause coronary insufficiency. We describe the case of a 75-year-old woman who had an isolated unruptured aneurysm of the left coronary sinus with intraluminal thrombus, which caused coronary artery compression. We performed successful surgical correction by closing the mouth of the aneurysm without aortic valve replacement or coronary artery bypass grafting. A review of the world medical literature revealed 19 cases of sinus of Valsalva aneurysms that hindered the coronary arterial flow. The previously published reports of this rare condition and its treatment are discussed herein. (Tex Heart Inst J 2002;29:40–4)

左瓦氏窦（sinus of Valsalva）动脉瘤极为罕见。此类动脉瘤压迫左冠状动脉是该病症的少见并发症，可引发冠状动脉供血不足。本文报告1例75岁女性患者，其罹患孤立性未破裂左冠状动脉窦动脉瘤且伴腔内血栓，该动脉瘤造成冠状动脉受压。我们通过闭合动脉瘤瘤口成功完成手术矫治，未行主动脉瓣置换术或冠状动脉旁路移植术。经检索全球医学文献，共发现19例阻碍冠状动脉血流的瓦氏窦动脉瘤病例。本文还综述了该罕见病症既往已发表的相关报道及治疗方案。（Tex Heart Inst J 2002;29:40–4）
