Abstract:【Objective】 To investigate the clinical effect of robot repair of atrial septal defect in adult patients. 【Methods】 The clinical data of 110 patients with secondary atrial septal defect admitted to our hospital were retrospectively analyzed. According to the different treatment methods, they were divided into observation group (robot atrial septal defect repair, n=57) and control group (transcatheter closure, n=53). The operation time, hospital stay, postoperative blood transfusion rate and postoperative complications were compared between the two groups. The right atrial diameter (RA), right ventricular diameter (RV), left atrial diameter (LA) and left ventricular diameter (LV) were compared between the two groups before and 6 months after operation.【Results】 The operation time, hospital stay and postoperative blood transfusion in the observation group were significantly higher than those in the control group (P<0.05). 6 months after operation, RA and RV in observation group and control group were lower than those before operation, the difference was statistically significant (P<0.05); LA and LV of two groups were not statistically significant (P>0.05); RA and RV of observation group were significantly lower than those of control group at 6 months after operation, the difference was statistically significant (P<0.05). The incidence of postoperative complications in the observation group was 5.26% (3/57), which was lower than 24.53% (13/53) of the control group, and the difference was statistically significant (χ2=8.200, P=0.004<0.05).【Conclusion】 Robot atrial septal defect repair plays an important role in the treatment of adult secondary atrial septal defect. It can significantly reduce postoperative RA and RV, and has high clinical safety.
