ABSTRACT

PURPOSE:

To study the angiographic anatomy of human coronary veins and the possibility of epicardial venous mapping through microelectrode catheters.

METHODS:

We evaluated 30 patients with sustained ventricular tachycardia using a catheter which provided occlusion of the coronary sinus ostium during venous angiography. They were 25 males, 5 females, ages ranging from 24 to 76 years (mean = 52.7). The veins were studied according to their number, caliber and distribution in the anterior and posterior wall of the left ventricle.

RESULTS:

Coronary sinus was catheterized in all patients. No discomfort or complication were observed. The number of veins from posterior wall of the left ventricle was 3.1 and anterior wall, 1.9, p < 0.05. The caliber of the coronary veins were anterior interventricular vein (distal segment = 1.19 +/- 0.22 mm, middle segment = 1.65 +/- 0.35 mm), posterior interventricular vein (distal segment = 1.83 +/- 0.47 mm, middle segment = 2.00 +/- 0.52 mm), left posterior vein (distal segment = 1.45 +/- 0.25 mm, middle segment = 2.49 +/- 0.92 mm); p < 0.05.

CONCLUSION:

The balloon occlusion technique for coronary venous angiography is feasible and safe. The number and the caliber (distal and middle) of the veins from the posterior wall of the left ventricle were significantly greater than those from the anterior wall. Anatomic conditions for venous epicardial mapping are more adequate in the posterior wall of the left ventricle.
