Early and Mid-Term Outcomes of Primary Repair After Atrioventricular Canal Defect: A Single-Center Eight-Year Experience

Background/aim: Surgical repair techniques and management of patients with atrioventricular septal defect (AVSD) have progressed over the last few decades. Early definitive interventions become choice treatment for these patients. Based on this background, we aimed to review early mid-term outcomes primary AVSD repair. Methods: A total 53 a mean age 3.45 ± 5.67 years underwent between January 2014 June 2021. The clinical data including age, type defect, associated co-anomalies, symptoms, pulmonary hypertension, etc. were collected assessed retrospectively. Mitral regurgitation (MR) as outcome was at 0, 1, 2, 5 years. Results: Among recruited patients, 35 (66.1%) male 18 (33.9%) female. Of complete done in 38 (71.69%) intermediate/partial 15 (23.1%) one patient incomplete type. Other co-anomalies anterior mitral leaflet (12 (22.6%)), atrial ventricular (VSD) (30 (56.6%)), patent ductus arteriosus (PDA) (11 (20.8%)). Different procedures surgical included patch closure, cleft repair, polytetrafluoroethylene (PTFE) VSD closure. After follow-up period 46.73 27.37 months. Overall mortality 3.78% (2/53), two reintervention due symptomatic severe MR. Conclusions: timely correction shows satisfactory results.
