Abstract

Objective To evaluate the transthoracic echocardiography(TIE)in transcatheter occlusion of atrial septal defect and analysis of the reasons for the failure.Methods Before occlusion,the size,shape of ASD and the remaining atrial septum length were measured,the shunt was observed by color Doppler flow imaging(CDFI).Results Forty-nine patents with ASD were occluded, including 8 failed.Size of ASD were 4-38(16.5±6.3)mm,and occluders size were 8-42(18.5±8.3)mm.Close correlation was found between the size of ASD measured by TIE and the size of occluders(P0.001).Conclusion TIE would be is a feasible, simple and effective method in ASD occlusion,subcostal two-antrum view,the short-axis view of great vessels and apical four- chamber view could clear reveal ASD to ensure successful occlusion.
