主动脉窦瘤破裂的超声心动图诊断

ECHOCARDIOGRAPHIC DIAGNOSIS OF RUPTURE OF VALSALVA SINUS ANEURYSM

本文报告我院１９８５～１９９２年间超声心动图诊断主动脉窦瘤破裂（ＲＶＳＡ）１７例，均为破入右心，其中破入右房１１例。超声心动图所测窦瘤及破口之大小与手术结果符合者１４例，ＲＶＳＡ后的血液动力学改变主要为左室或双室容量负荷过重，本组伴发之损害以主动脉瓣关闭不全最常见共６例，心包积液４例。

The echocardiographic findings of 17 cases with rupture of Valsalva sinus aneurysm into the right heart(RVSA) from 1985 to 1992 were studied and were compared with the results of operation or angiography to investigate the echocardiographic evaluation of RVSA. Echocardiographic diagnosis of RVSA includes mainly three aspects:1.Direct showing of rupture opening, sinus aneurysm,and size of the aneurysm.Size of rupture opening was closely related to that found during operation in this study(r=0.78-0.95,p<0.001).2.Secondary hemodynamic changes resulted from rupture of sinus aneurysm or volurne overload in the left or both veniricles.3.Detection of associated cardiac abnormalities,such as aortic insufficiency,pericardiac effusion.It is concluded that echocardiography is a valuable and reliable method in diagnosing RVSA.
