Fig. 8From: Computed Tomography and Magnetic Resonance Imaging of the Coronary Sinus: Anatomic Variants and Congenital AnomaliesA 53-year-old male with an anomalous communication of the left superior pulmonary vein (LSPV) to the CS. (a, b) Short axis maximum intensity projection CCT images and (c) volume-rendered image clearly delineate the course of the CS in the atrioventricular groove posterior to the left atrium, receiving drainage from the LSPV and opening into the right atrium. (d) CMR with phase-contrast analysis demonstrates the same caudal direction of flow of the anomalous vein and the descending aortaBack to article page
