Abstract Objective: To assess the follow-up outcome of echocardiography in patients who had interventional therapy of atrial septal defects(ASD). Methods: Of the 778 patients with ASD secundum, 276 were men and 502 women, male∶female is 1∶1.8, age ranged from 2 to 74 years old, mean age (29.6±9.6)years old. All of the 778 ASD patients, 765 patients had central type and single ASD, 13 patients had multiple ASD. In addition, 91 patients accompanied with other malformations. Toshiba Type 6000, Philips IE33 color Doppler ultrasonography and Type 1500 esophagus color Doppler ultrasonography were used. The frequency of detecting probe was 2.5MHz and 5MHz. All the patients after interventional therapy were checked by TTE and inner diameters of the heart chamber were recorded, especially the inner diameter of RVOT and RV. In addition, the closer’s position, residual shunt, valvular regurgitation and cardiac status were observed. Follow-up evaluation was performed in 778 patients by TTE at 1, 3, 6 and 12 months after discharged. The section of TTE was apex cordis and parasternal 4-chamber plane, subappendix 4-chamber and 2-atrium plane, main artery and subappendix short-axis plane. Results: The incidence rate of interventional operation’s complication was 2.3%, including 5 patients had closer shedding, 2 patients had brain infarction, 5 patients had pericardial effusion, 4 patients had residual shunt and 1 patient had pulmonary arteriovenous fistula. Conclusion: TTE had clinical value in follow-up examination for patients who had ASD interventional therapy.
