Abstract Objective: To explore the diagnostic value of color Doppler flow imaging(CDFI) and left ventricular angiography in the diagnosis of ventricular septal defect(VSD) with aneurysms. Methods: Twenty-seven cases of VSD with aneurysms were confirmed by CDFI and left ventricular angiography. Before occlusion the size and the type of membranous aneurysm, distance from VSD to the aortic valve or tricuspid valve were measured. The diameter of occluder waist was measured after occlusion. Results: The detection rate of membranous aneurysm was 100% via left ventricular angiography and 92.6% via CDFI. The detection rate of the types and the size of membranous aneurysm via CDFI and that via left ventricular angiography had significant difference(P<0.05). The two methods in the measurement of the orifice of VSD had no significant difference but in the measurement of the distance from VSD upper margin to the ring of aortic valve had significant difference(P<0.05). The diameter of occluder waist was significantly correlated with the size measured by CDFI or angiography. Conclusion: There was a positive correlation between CDFI and left ventricular angiography in estimating membranous aneurysm before occlusion of VSD. They possess very important value in the transcatheter closure of VSD with membranous aneurysm.
