Objective To evaluate the feasibility and effectiveness of secundum atrial septal defect(ASD)occlusion with the septal occluder through right-chest small incision. Methods The clinical data of 140 secundum ASD patients (47 males and 93 females) aged 3-63 years who were treated in our center from August 2004 to July 2014 were retrospectively analyzed. The diameter of ASD was 6 to 36 mm. Under general anesthesia, all patients underwent intraoperative transtsophageal echocardiography (TEE), during which no associated cardiac deformity was found. All patients received ASD occlusion via a small incision (3-4 cm) at the right anterior chest. The occluders were released with the help of TEE. Results The atrial septal defect closure was successfully completed in 134 cases. Six cases received surgical closure of ASD after the failure of occlusion. The reasons of conversion included postoperative dislodgement of occlusion device (n=2, both were central type with large size) and technically unsuitable for occlusion (n=4, in whom residual shunt was found in 2 case, sieve pore type in 1 case, and intraoperative dislodgement in 1 case). All of these 6 patients were treated surgically under cardiopulmonary bypass. No dislocation of the device or atrial shunt was found within 3 to 48 months after the operation. Conclusion Occlusion via small chest incision of ASD under TEE guidance without cardiopulmonary bypass is a safe, minimally invasive, effective, and convenient treatment and worth clinical application.
