Abstract

Objective: Evaluate the short-term outcomes of minimally invasive surgical repair for partial atrioventricular septal defect at Heart Center-Vietnam National Children’s Hospital. Methods: From August 2019 to August 2022, all patients diagnosed with partial atrioventricular septal defect who underwent minimally surgical repair using the right vertical infra-axillary mini-thoracotomy approach at Vietnam National Children’s Hospital were retrospectively reviewed. Results: There were 16 patients collected during the study period. There were 7 males and 9 females. Patients' median age and median weight was 23.8 months (IQR, 13.7-57.7 months) and 10.7 kg (IQR, 8.3-14.8 kg). Fourteen patients (87.5%) had moderate mitral valve regurgitation, and two patients (12.5%) had mild mitral regurgitation before surgery. Single lung ventilation was applied for all patients during surgical repair. The mean time for surgical repair and aortic cross-clamp time was 185 ± 31.6 minutes, and 71.7 ± 21.4 minutes, respectively. There was no mortality in this study. One patient required permanent pacemaker due to complete atrioventricular block. One patient was extubated immediately in the operating room after operation. The mean ventilation time was 10.4 ± 7.4 hours. Last visit follow-up revealed no residual shunt across the interatrial septum, and all patients had no or trivial mitral valve regurgitation at the echocardiography. There was no chest deformity at the last follow-up of all patients. Conclusion: Short-term results of minimally invasive surgical repair for treatment of partial atrioventricular septal defect were satisfactory. Further investigation with longer time of follow-up and bigger cohort is necessary.
