Abstract：Objective: To evaluate the characteristics and regularity of echocardiographic in the diagnosis of rupture of aortic sinus aneurysm(RASA) accompanied with the ventricular septal defect(VSD), by analyzing the relationship between the RASA and VSD. Methods: The features of two dimension ultrasound and color Doppler flow imaging of 59 patients with ASA were retrospectively analyzed and compared with surgical results. Results: In the 59 patients, 51 patients with ASA were originated from right coronary sinus, ruptures were observed in 46 cases; and VSD were observed in 39 cases(66%); and aortic insufficiency were observed in 26 cases(44%)(in which aortic valve prolapse were observed in 9 cases(15%)). The location, size, rupture, drainage chamber of RASA diagnosed by ultrasonography were all confirmed by the surgical results; the size of VSD was underestimated by ultrasonography in 3 cases, and 2 VSD cases were misdiagnosed(stem inferior type). Conclusions: Echocardiography can diagnose RASA accompanied with VSD accurately, but VSD could be possibly misdiagnosed or underestimated ventage size. In order to improve diagnose more accurately and reduce misdiagnose and missed diagnosis, it is very important to observe the echocardiographic characteristics carefully and precisely by combined two dimension ultrasound and color Doppler flow imaging. This method could be as an optimizing in the diagnosis way to diagnose RASA combined with VSD.
