Application of transthoracic and transesophageal echocardiography in interventional occlusion for atrial septal defect

Objective:To evaluate the application of transthoracic and transesophageal echocardiography in interventional occlusion for atrial septal defect(ASD).Methods:A total of 33 patients with ASD were carefully selected.Patients with the defect diameter ≥ 25 mm diameter,multiple ASD and unclear soft edge were examined with transesophageal echocardiography,in order to record the number,diameter and the edge defect.Qualified patients with ASD were occluded by use of Amplatzer.And the success rate,residual shunt and complications were observed.Results:A total of 16 patients with diameter 25 mm had successful treatment;2 patients with two-hole-defect,4 cases with unclear edge and 11 cases with diameter ≥25 mm were detected by transesophageal echocardiography.According to the detection result,suitable occluder was selected.One case with diameter of 35 mm failed to occlusion,and turned to surgical repair.Transthoracic echocardiography after surgery showed no residue shunt,and echocardiography after 24 h,7 d,1 month,3 months and 6 months all showed no residue shunt,hemolysis or effect on valave.Conclusion:Transthoracic echocardiography combined with transesophageal echocardiography can increase success rate of interventional occlusion for ASD,and is worthy clinical application.
