Clinical Contrast Research Of Interventional Device Closure Of Atrial Septal Defects Through Two Kinds Of Different Paths

Objective To compare the merit and shortage of interventional device closure of isolated secundum atrial septal defects(ASD) through cardiac catheter or chest small incision .Methods Retrospective analyses of the clinical results of interventional device closure of isolated secundum ASD through cardiac catheter or chest small incision for 41 patients from September 2004 to March 2007 was performed . Among them 12 patients underwent device closure of ASD through chest small incision (chest small incision group) and 29 patients underwent device closure of ASD through cardiac catheter (cardiac catheter group).Results There were no deaths and blood transfusion in either group . Interventional device closure through chest small incision was successful in all 12 patients , while interventional device closure through cardiac catheter was successful in 26 of 29 cases. The mean procedure time of chest small incision group was significantly shorter than that of cardiac catheter group (76.25±20.24 VS 92.56±34.18 min, P<0.05). The mean occluder delivery times of chest small incision group was less than that of cardiac catheter group (1.0 VS 1.48±0.95 times , P<0.05). Two major complications occurred in cardiac catheter group , but no one occurred in chest small incision group . Forty-one patients were followed-up from 1 months to 30 months , all of patients were free from residual leak and occluder dislodgment.Conclusion Both paths can achieve secure occlusion for isolated secundum ASD with mild trauma and fast postoperative recovery and good cosmetic result. Interventional device closure of ASD through cardiac catheter involves slightly low success rate and relatively narrow indication and difficult technique whereas through chest small incision offers relatively wider indication and simple technique and higher success rate or safety.
