目的总结了９例主动脉窦瘤破裂的临床与超声心动图特征。方法用彩色多普勒二维超声心动图诊断９例青年无痛性主动脉窦瘤破裂并经手术证实。结果９例中仅１例有诱因，８例短期内出现心力衰竭表现。超声心动图可以直接显示破口数目、大小、分流及心脏容量负荷过重扩大的征象。结论对青年无痛性主动脉窦瘤破裂，超声心动图是诊断的可靠方法，为手术决策提供依据，但应注意合并症的存在
Objective To summarize the clinical and echocardiographic features of 9 cases of ruptured sinus aneurysm. Methods Nine cases of young painless sinus aneurysm were diagnosed by color Doppler echocardiography and confirmed by operation. Results of 9 cases, only 1 incentive, 8 cases of short-term heart failure performance. Echocardiography can directly show the number of break, size, shunt and cardiac capacity overload overweight signs. Conclusion It is a reliable method to diagnose young painless sinus aneurysm rupture and echocardiography, which provides a basis for surgical decision-making, but should pay attention to the existence of comorbidities
