Unroofed coronary sinus (UCS) is among the rarest congenital heart malformations in pediatric practice. Often, they are associated with persistent left superior vena cava (PLSVC) draining into the left atrium, and in this situation, there is a double intracardiac shunt, right-to-left and left-to-right. They are asymptomatic in the majority of the cases. Each ordinary imagistic method (transthoracic echocardiography, contrast transesophageal echocardiography, angiography) can be helpful in finding the diagnosis, but enhanced computed tomography scan can give an irrefutable diagnosis. The surgical intervention may consist in the recreation of a roof for the coronary sinus, and anastomosis of the PLSVC to the right atrial appendage.
