Anatomy of the Pulmonary Circulation and Outcomes in Tetralogy of Fallot With Major Systemic‐to‐Pulmonary Collaterals and Unilateral Pulmonary Artery of Ductal Origin

Key Points

• To explore the unique anatomy of pulmonary circulation in patients with Tetralogy of Fallot and assess treatment outcomes.
• Analyzed cases of Tetralogy of Fallot with unilateral pulmonary artery and major systemic-to-pulmonary collaterals.
• Evaluated the effectiveness of stenting the ductus arteriosus in the neonatal period followed by pulmonary artery reconstruction.
• Assessed patient outcomes based on the anatomical configuration of major aortopulmonary collateral arteries.
• Excellent outcomes were observed in patients treated with stenting and subsequent repairs.
• Anatomical variations play a significant role in the timing and type of interventions performed.
• Stenting of the ductus arteriosus is crucial for ensuring appropriate flow to the pulmonary arteries.
