PERSISTENT LEFT SUPERIOR VENA CAVA WITHOUT RIGHT SVC DURING FETAL LIFE

Persistent left superior vena cava (SVC) without the right SVC is very rare and occurs in 0.07%–0.13% of patients with congenital heart defects. An enlarged coronary sinus detected during cardiac examination in the prenatal period is the first finding that raises suspicion for this anomaly. In this report, a patient was presented who was referred with the prediagnosis of cor triatriatum sinister in the antenatal period and diagnosed with isolated persistent left SVC.
