Appearance of collateral circulation in the absence of total occlusive spastic coronary artery: a case report.
Development of coronary collateral vessels is described in a patient with coronary artery spasm associated with ST-segment depression. The collateral vessels disappeared after spasm was relieved and the ST segment was normalized, suggesting that the collateral vessels occurred during coronary artery spasm and were localized to the perfused ischemic area to prevent transmural myocardial ischemia.
