Axial and Coronal images with Sequential gating, cardiac phases utilized of 40-80% on CCTA (kVp=120 with care dose variable mAs and slice thickness of 0.7 mm with 0.4 overlap) demonstrating the difference in opacification based on the Hounsfield Units (HU). In image (A) the coronary sinus HU is 309.3+-28.3, where the HU is 159.0+-24.8 in the right atrium and 379.3+-12.8 in the left ventricle as shown in images (B) and (C), respectively. Image (D) highlights the course of the opacified fistula on maximal intensity projection images.

CCTA demonstrated a venous fistula connecting the coronary sinus (CS) with the distal portion of the left anterior descending artery (LAD), occupying the territory of a left posterior descending artery (L-PDA) and corresponding in distribution with the patient's stress-induced wall motion abnormalities (Figures 1 and 2).
3D rendered image as well as minimal intensity projection images with Sequential gating, cardiac phases utilized of 40-80% on CCTA (kVp=120 with care dose variable mAs and slice thickness of 0.7 mm with 0.4 overlap) of the course of the fistula connecting the coronary sinus (CS) and the distal left anterior descent (LAD) artery.
