Abstract

125 patients (89 female patients; average age, 31.6 ± 18.7 years; age range, 3–72 years) with secundum-type ASDs were selected for this study. Three 5-mm trocars and one 12-mm trocar were used;  only  the  superior  vena  cava  was snared. The pleural and pericardial cavities were filled with CO2. All ASDs were closed using artificial patch, continuous suture; tricuspid valve regurgitations (TVR) were repaired and the anomalous pulmonary veins were drained to the left atrium. Surgeries were performed by one surgeon on the beating heart. No major complications or deaths occurred. No residual shunt was detected. Patients were divided into three groups: group I (without tricuspid valve repair), group II (DeVega), and group III (Ring annuloplasty). There were significant learning curves for the operation time and CPB time in  each group. In without tricuspid valve repair group, operation time and CPB time were: y = 400 – 52 ln(x) (r2 = 0.616) and y = 293 – 51 ln(x) (r2 = 0.852), respectively. In DeVega group, operation time and CPB time were: y = 271 – 29 ln(x) (r2  = 0.236) and y = 178 – 34 ln(x) (r2  = 0.659), respectively. In Ring annuloplasty group, operation time and CPB time were: y = 318 – 44 ln(x) (r2  = 0.565) and y = 184 – 29 ln(x) (r2  = 0.685), respectively. The length of stay in the intensive care unit was 25,3 ± 20,7 hours. Patients were discharged from the hospital 8 days after the operation.
