    The modified right vertical infra-axillary thoracotomy (MRVIAT) technique enhances surgical outcomes for partial atrioventricular septal defect (PAVSD) repairs.

  • 2

    In a study of 64 patients, MRVIAT was performed successfully without transitioning to median sternotomy or significant complications.

  • 3

    The average operative duration for MRVIAT was 177 minutes, with a noted decrease in duration as surgical experience increased.

  • 4

    No moderate or severe valvular regurgitation was observed during follow-up, indicating preserved cardiac function post-surgery.

  • 5

    MRVIAT offers aesthetic benefits with a smaller incision, potentially improving patient satisfaction across a wide age range.
