Objective(s): The arterial switch operation continues to be the standard of care for dextro-transposition of the great arteries (d-TGA). However, certain conditions may preclude an arterial switch operation. We report our center’s experience with the Senning operation in neonates.
Methods: This is a single-center retrospective review of neonates with d-TGA who underwent the Senning operation from May 2022 to January 2024.
Results: During the study period, 4 male patients with an average weight of 4.28±1.12kg underwent the modified Senning operation. Median age at operation was 25 days (range 15-100 days). Pre-operative transthoracic echocardiogram demonstrated moderate-to-severe pulmonary valve stenosis with subpulmonary obstruction in all patients. Three patients (75%) had complex coronary anatomy and 3 patients (75%) had a small muscular ventricular septal defect. A gore-tex patch was used to construct the floor of the systemic venous pathway and in-situ pericardium was used to construct the pulmonary venous pathway. The average cross-clamp time was 98.25±9.43 minutes. The average cardiopulmonary bypass time was 179.5±39.37 minutes. Median length of stay was 27 days (range 24-29 days) and median time to follow-up was 114 days (range 65-594 days). Survival was 100%. There were no incidences of atrial arrhythmias, diaphragmatic paralysis, or systemic and/or pulmonary venous baffle obstruction or leak. Right ventricular and tricuspid valve function was preserved in all patients.
Conclusions: The Senning operation is a good option in certain subgroups of patients with d-TGA unsuitable for the standard arterial switch operation. It can be performed safely in neonates with excellent outcomes.
