Congenital anomalies of the venous system are rare, involve the inferior vena cava (IVC), a persistent left superior vena cava (PLSVC), and the left hepatic vein (LHV), and can make cardiac diagnostic and therapeutic procedures difficult.

Case presentation

We present a 67-year-old woman without heterotaxy syndrome associated with interruption of the left IVC that continued with the hemiazygos vein system, a PLSVC, and an anomalous LHV draining the into coronary sinus (CS). The venous anomalies caused a CS aneurysm. The anomalies were demonstrated by echocardiography and the diagnosis was established by contrast-enhanced computed tomography. Three days later, a coronary artery bypass graft was performed, which confirmed the diagnosis. Half a month after surgery, the pain had been relieved and the patient was discharged from the hospital.


Echocardiography is a useful modality to diagnose and assess anomalies of the CS, including CS aneurysms. Congenital anomalies of the venous system in this case were all due to embryonic development abnormalities. Contrast-enhanced computed tomography provides a more comprehensive view of the entire course of abnormal veins.
