决定慢性主动脉瓣关闭不全的最佳手术治疗时间是临床心脏病学中一个难题.主动脉瓣闭不全的病人尽管左室容量负荷过重,仍可较长期无症状.但一旦出现呼吸困难、心绞痛、晕厥前或晕厥等症状,病程进展常十分迅速,平均生存期仅3～5年.因此,大多数临床医师均同意症状严重的患者应予换瓣手术.然而,轻度或无症状病人是否应予手术,仍是一个难题.如对所有无症状病 The optimal surgical treatment for chronic aortic regurgitation is a difficult issue in clinical cardiology. Patients with aortic regurgitation may remain asymptomatic over the long term, despite prolonged left ventricular volume overload, but in the event of dyspnea, Angina, pre-syncope or syncope and other symptoms, the course of progress is often very rapid, with an average survival of only 3 to 5 years Therefore, most clinicians agree that patients with severe symptoms should be replaced by flap surgery, however, mild or asymptomatic patients Whether it should be surgery, is still a problem, such as for all asymptomatic disease
