Abstract

Anomalies of systemic venous return represent rare congenital malformations, accounting for approximately 2% of all such cases. The occurrence of congenital heart disease patients exhibiting an isolated persistent left superior vena cava has been observed at a frequency of 0.07 to 0.13%. Due to their rarity, these anomalies are frequently associated with chromosomal abnormalities. These forms may manifest in isolation or in conjunction with other congenital heart conditions. The following report details a case of a patient two-year-old.
