Occlusion of Atrial Septal Defect via Small Chest Incision:Report of 41 Cases / 中国微创外科杂志

ABSTRACT

Objective To discuss the surgical outcomes of atrial septal defects(ASD) by closing the ostium secundum via small chest incision.MethodsTotally 41 cases with ASD were treated by occlusion via a small incision(3-4 cm) at the right anterior chest.After cutting the pericardium,the right atrial was sutured with double ring and a special occluding device was inserted to close the ostium.Afterwards,under the guidance of transthoracical or transesophageal echocardiography,the satisfiable position for the occluder was confirmed by repeated testing with the protect string.After that,the right atrial and the occluder were sutured by a needle thread for fixation.ResultsOf the patients,the procedure was successfully completed in 39 cases.The mean operation time was 45 to 95 minutes(mean,60 minutes).The patients were discharged from our hospital in 3 to 6 days.No dislocation of the device or atrial shut was found in 2 to 24 months after the operation.Two patients were converted to open surgery because of failure in the occlusion.ConclusionOcclusion via small chest incision is safe,minimally invasive,and convenient procedure for ASD.
