ABSTRACT Introduction: The procedure of choice for treatment of truncus arteriosus is one-stage repair within the first few months of life. Establishing right ventricle-pulmonary artery direct continuity without conduit can be a good alternative in the absence of valved conduits in developing centers. Methods: Between January 2021 and June 2021, a total of five patients (three males, two females) underwent definitive repair of truncus arteriosus without an extracardiac conduit. We used the Barbero-Marcial technique to allow age-related growth, eliminate the risk of conduit-related complications, and to avoid forcing a conduit to place in a very small mediastinal space. Results: The patients’ mean age was 31.2 days (11-54 days). Their mean bodyweight was 3.2 kg (2.7-3.8kg). Mean postoperative intensive care unit stay was 39.6 days (7-99 days). There were two mortalities in the intensive care unit on postoperative days 12 and 61 due to lung-related problems. The remaining three cases’ mean ventilation time was 15.6 days (8-22 days). Conclusion: Having access to a valved conduit is still challenging for some centers, and the non-conduit repair technique defined by Barbero-Marcial can be a successful, life-saving alternative easy for young surgeons to perform in newly based centers.
