Case Report


Introduction: The coronary sinus is responsible for venous drainage of the heart. Congenital anomalies of the coronary sinus are rare and typically associated with other anomalies, such as atrial septal defects or other congenital heart malformations.

Clinical Findings: We present a case of incidentally found atresia of the coronary sinus ostium with associated persistent left superior vena cava. This case involved a 52-year-old patient who initially presented with a supraventricular tachycardia and elevated troponin.

Clinical Course: The patient underwent cardiac workup with a coronary computed tomographic angiography scan. This scan showed no obstructive coronary artery disease, but did show congenital atresia of the coronary sinus and a persistent left superior vena cava.

Conclusions: This case shows that coronary computed tomographic angiography is an excellent modality for identifying anomalous coronary venous return and congenital abnormalities of the coronary sinus.
