Purpose

To investigate the coronary venous system and its relation to adjacent structures using 256-slice computed tomography CT.

Materials and Methods

The study consisted of 102 patients who underwent coronary CT angiography CTA using 256-slice CT. For each patient, the coronary venous system and its relation to adjacent structures were evaluated. The appropriate locations and diameters of the posterior interventricular vein PIV, posterior vein of the left ventricle PVLV and the left marginal vein LMV were detected. The paired student-s t test was used to evaluate the difference between the diameter of the coronary sinus CS ostium in anteroposterior direction and that in superoinferior direction.

Results

The CS, great cardiac vein GCV, PIV, and anterior interventricular vein AIV were visualized in all cases. It was possible to evaluate at least one main vein with adequate caliber and regular course for cardiac resynchronization therapy CRT in 96.1% of these cases. The diameter of the CS ostium in superoinferior direction 11.7±2.1 mm was larger than that in anteroposterior direction 9.0±2.0 mm t = 13.511, P<0.05. For the majority of the cases, the CS-GCV was located above the level of the mitral valve annulus MVA, while the left circumflex coronary artery LCX was coursed between the CS-GCV and the MVA. LMV had more intersection with the circumflex or circumflex marginal than PVLV.

Conclusion

256-slice CT provides superior noninvasive evaluation of the coronary venous system which has important clinical implications.
