Dissection of the sinus of Valsalva is a rare and life-threatening event. It often occurs during percutaneous coronary intervention in the right coronary artery (RCA). Dissection flap usually involves the RCA and the right sinus of Valsalva. Here we report two extremely rare cases of spontaneous dissection limited to the non-coronary sinus of Valsalva, causing severe aortic valve regurgitation: a male aged 51 years presenting with back pain, weakness, and presyncope and another male aged 71 years presenting with orthopnea and weakness. The dissection was found by transesophageal echocardiography. Surgical treatment was successful for both patients. One year after surgery, both patients were asymptomatic and follow- up transthoracic echocardiography did not show any abnormality.
主动脉窦破裂是一种罕见且危及生命的事件。它常发生于右冠状动脉（RCA）的经皮冠状动脉介入治疗期间。剥离瓣通常累及RCA和主动脉右窦。在此，我们报告两例极其罕见的自发性剥离局限于主动脉无冠窦的病例，导致严重主动脉瓣反流：一例51岁男性，表现为背痛、乏力和晕厥前症状；另一例71岁男性，表现为端坐呼吸和乏力。经食管超声心动图发现了剥离情况。两名患者手术治疗均成功。术后一年，两名患者均无症状，随访经胸超声心动图未显示任何异常。
