无症状重度主动脉瓣狭窄患者手术与非手术治疗探讨

目的比较无症状重度主动脉瓣狭窄患者手术治疗与非手术治疗心源性死亡率的差别。方at分析我院心脏外科2007年1月-2010年12月122名无症状重度主动脉瓣狭窄患者心源性死亡率，手术组65例，行主动脉瓣置换手术，非手术组57例选择常规治疗。结朵手术组心源性死亡率明显低于非手术组。结论对于无症状的重度主动脉瓣狭窄患者手术及非手术治疗，仍存在争议，但若存在高危因素，则需考虑行手术治疗。

Study on Treatment of Surgical or Non-surgical for Asymptomatic Patients with Severe Aortic Stenosis

Objective To compare the cardiac mortality of asymptomatic patients with severe aortic stenosis treated by surgical or non-surgical. Methods To analyze 122 patients cardiac mortality which were asymptomatic patients with severe aortic stenosis from January 2007 to December 2010 in the department of cardiac surgery. Among of them, 65 of the patients received aortic valve replacement, 57 underwent conventional treatment. Results surgical group of cardiac mortality was significantly lower than the non-surgical group. Conclusions Surgical and non-surgical treatment for asymptomatic patients with severe aortic stenosis is still controversial. But if there are risk factors, surgical treatment need to be considered.
