Abstract
Complete occlusion of the main LCA is associated with a poor prognosis if the RCA becomes severely occluded. The functional role of collateral circulation is critical in this situation. This study lends support to the hypothesis that coronary collateral circulation can provide critically needed myocardial blood flow via right to left collaterals. Not surprisingly, left ventricular function was maintained in 4 of the 5 patients studied who had main LCA occlusion and well-developed collateral circulation.
