Unroofed coronary sinus (UCS) represents the rarest type of atrial septal defect, with incidence less than 1% of all atrial septal defects, or less than 0.1% of all congenital heart anomalies. A case report of a 57-year-old man with four years of misdiagnosed UCS is presented. The patient showed dyspnoea, angina pectoris, and a new onset of atrial fibrillation. The diagnosis of UCS was finally established on the basis of right-sided cardiac catheterization, echocardiography, and computer tomography. Defect roofing with redirection of the coronary sinus into the left atrium was performed. UCS is in 75% of cases associated with other heart anomalies, especially persistent left superior vena cava. For isolated UCS, closing via the path from the side of right atrium is sufficient therapy with good long-term results. Persistence of left superior vena cava requires a technically serious occlusion of the defect from the left atrium or a redirection of the persistent vein itself.
