Objective:

To assess the clinical results and surgical viability of the modified right vertical infra-axillary thoracotomy (MRVIAT) technique for the correction of partial atrioventricular septal defect (PAVSD), highlighting its significance in minimally invasive surgery.

Key Findings:
  • All 64 patients had successful repairs without transitioning to median sternotomy.
  • No fatalities or significant complications were reported.
  • The average age of patients was 12.8 years, with a median body mass of 55.8 kg.
  • The average operative duration was 177 minutes, with a mean cardiopulmonary bypass duration of 98.2 minutes.
  • One patient required reoperation due to patch dehiscence, but no moderate or severe valvular regurgitation was observed during follow-up.
  • Demographic details such as age range and body mass index could be included for better context.
Interpretation:

The MRVIAT method is a safe and effective approach for PAVSD repair across a wide age range, offering aesthetic benefits that may significantly improve patient satisfaction.

Limitations:
  • The study is observational and conducted at a single center, which may limit generalizability and introduce potential biases.
  • The sample size is relatively small, and long-term outcomes need further investigation.
Conclusion:

The MRVIAT technique provides a minimally invasive option for PAVSD repair, demonstrating favorable outcomes and patient satisfaction.
