[Coronary collaterals and function of the left ventricle. Practical applications of a collateral score].
The most important collateral pathways in the coronary artery system goes through the apex, the ventricular septum, left and right atrial branches and the ventricular wall of the left ventricle. In a collective of 52 patients who underwent aortocoronary-bypass surgery we controlled the collateral circulation and left ventricle function. Patients with multiple-vessel-disease had in 71% good collateral circulation and the collateral score was more than twice as high as in patients with one-vessel-disease. In addition we compared the LVEDP in these 52 operated patients and in 52, whose condition did not permit coronary surgery. The enddiastolic pressure is lower in patients with good collaterals and was also better in patients who underwent surgery.
