Objectives To evaluate the value of colour Doppler echocardiography (CDE) in occlusion of rupture of aortic sinus aneurysm (RASA).
Methods Fifteen patients with RASA were indicated for interventional occlusion by CDE. CDE take part in all the process as monitoring in the occlusion operation, judging the effect after occlusion and follow-up.
Results According to the characteristics images of CDE, we correctly confirmed the ruptured sinus and the chamber it ruptured into, any complications, and successfully occluded the ruptures in all 15 cases.
Conclusions CDE plays very important roles in case of RASA occlusion. It can defined the ruptured sinus of aorta and the ruptured-into chamber, the diameter of the rupture, and rule out complications as ventricular septal defect before operation which is the most essential for the success of the occlusion. CDE can be used to monitor the correct implantation of the occluder, evaluate the residual shunt signals and the impingement on the aortic valve during the procedure and follow-up.
