AbstractA case of extracardiac noncoronary sinus Valsalva aneurysm was reported. A 11-year-old male with history of mild AR was admitted to the hospital due to severe AR. Echocardiography revealed that the severe AR and an aneurysm in the posterior part of the ascending aorta. Angiography revealed that the origin of the aneurysm was noncoronary sinus. Operative findings showed that the aneurysm sized 23 mm by 25 mm was an extracardiac type which grew posteroinferiorily at the left side of noncoronary sinus and that the dilation. Neither aortic valve nor the aortic route showed degenerative change. The ptosis of the valvular ring due to aneurysmal dilation of the noncoronary sinus caused AR. Then, valve repair composed by commissuroplasty and commissural suspension was carried out. And intraluminal patch closure technique in which the longitudinal diameter of patch was half of that of the aneurysm was effective on suspension of the valvular ring. Postoperative echocardiography showed decreasing of AR.
