Unobstructed infracardiac total anomalous pulmonary venous connection in a 7-month-old infant: A rare case report.

Total anomalous pulmonary venous connection (TAPVC) is a rare form of congenital heart disease that is typically diagnosed in neonates. TAPVC has four subtypes, with the infracardiac type at risk of obstruction. TAPVC is usually diagnosed in newborns but can occur in other age groups. In this case, a 7-month-old male with recurrent cyanotic episodes was diagnosed with TAPVC of the infracardiac type using computed tomography angiography. The patient underwent successful surgical repair with a favorable postoperative course and was discharged in stable condition, and further follow-up was not possible beyond 2 months. This case emphasizes the importance of early recognition and management of this condition to prevent the progression of subsequent complications.
