CTICasesCoronary Ventricular Fistula
Imaging findings
CT angiogram demonstrates a middle cardiac vein communicating directly with the lumen of the left ventricle near the apex, with retrograde contrast filling of the vein. The vein also communicates with the left and right atria.
Key takeaways
Congenital coronary venous fistulas are rare vascular anomalies where cardiac veins directly communicate with a cardiac chamber (e.g., left ventricle), resulting in altered contrast enhancement dynamics on CT.
