No other congenital abnormality was identified during this CTA examination such as abnormal
coronary vein drainage into the left atrium or an atrial septal defect.
Iatrogenic coronary artery fistulas are seen in only 0.25% of cases and typically involve coronary artery to
coronary vein communication [4, 5].

coronary vein varix; this was embolized with an Amplatzer type II plug (St.
PV, portal vein; SMV, superior mesenteric vein; CV,
coronary vein; IMV, inferior mesenteric vein; SA, splenic artery; SV, splenic vein; LGEA, left gastroepiploic artery; LGEV, left gastroepiploic vein; SGA, short gastric artery; SGV, short gastric vein.
The diameter of the CS is also variable and is dependent on the loading conditions, presence and extent of atrial myocardium with the
coronary vein. At the level of the A-V sulcus, the anterior surface of the CS is separated from the atrial and ventricular myocardium by connective and adipose tissue, precluding it from an intramural location in the atrioventricular sulcus.
