abstract = {Background: To evaluate the role of CT angiography (CTA) in the diagnosis and subcategorization of unroofed coronary sinus syndrome (URCS).
Methods: We retrospectively analyzed 46 URCS patients diagnosed by CTA. Based on the defect location and size of coronary sinus (CS), URCS was divided into four types: complete defect as type I, partial defect of proximal CS as type II, partial defect of distal CS as type III, partial defect in which a communication occurs between CS and left atrial as type IV. According to presence of left superior vena cava (LSVC), all types were divided into 2 subtypes as a and b. All 46 patients underwent echocardiography.
Results: According to subcategorization of URCS by CTA, type I was observed in 23 cases (Ia 7, Ib 16), type II in 10 cases (IIa 3, IIb 7), type III in 12 cases (IIIa 3, IIIb 9), and type IV in 1 case classified as IVb subtype. In these 46 cases, 21 were detected by echocardiography as URCS (46%). The sensitivity of echocardiography in detecting URCS was significantly lower compared with cardiac CTA (P},
