    Abstract:
    BACKGROUND: The superior sinus venosus atrial septal defect is a congenital communication between the left and right atria. Open surgical approach by patch closure has historically been the only treatment option. Recently, a transcatheter approach has been developed. This study aims to compare the efficacy and safety of surgical and transcatheter approach in treatment of sinus venosus atrial septal defect. METHODS: Between March 2010 and December 2020, 58 patients (median age: 45.4, range 14.8-73.8) underwent either surgical or transcatheter correction of superior sinus venosus atrial septal defect with partial anomalous pulmonary venous drainage. RESULTS: Twenty-four patients (median age: 35.4, range 14.8-66.8) underwent surgery while 34 patients (median age: 46.8, range 15.5-73.8) had a transcatheter treatment. During the catheterization era, 41 patients was considered suitable for a transcatheter closure. In 5 patients, surgery was the patient's or referring physician's choice. In 2 cases, the procedure was unsuccessful; the remaining 34 were successfully closed (94.4% of cases). Intensive care unit stay (median of 1 day, range 0.5-4, vs. 0, range 0-2, p < 0.0001) and hospital stay (median 7 days, range 2-15 vs. 2 days, range 1-12, p < 0.0001), were significantly longer in the surgery group. Total early complication rate, consisted on procedural and in-hospital complication, were higher in the surgical group (62.5% vs. 23.5%; p = 0.005). However, complications in both groups were clinically mild. At follow-up, a small residual shunt was present in 6 patients (surgery group: 2 pts; catheterization group: 4 pts; p: NS). Imaging studies showed significant improvement of right ventricular size and unobstructed pulmonary venous return in all patients. No late complications occurred at follow-up. CONCLUSIONS: Transcatheter correction of sinus venosus atrial septal defect is effective and safe in selected patients and may be considered as a valid alternative to surgery.
