Fig. 10From: Computed Tomography and Magnetic Resonance Imaging of the Coronary Sinus: Anatomic Variants and Congenital AnomaliesA 26-year-old female with Ebstein anomaly, CS ostial atresia and a persistent LSVC draining into the left atrium via the CS. a, b Multiplanar reformat CT images demonstrate communication between the CS and the left atrium (a, long arrow) via an anomalous vein (b, asterisk) without connection to the right atrium. Coronary venous drainage occurs through a network of collateral veins feeding directly into the right atrium (a, short arrows)Back to article page
