A graphic computerized system for reporting and analysis of coronary angiograms

A graphic computer based system for coronary angiographic reporting and data storage has been developed. It uses a multisegmental model of the coronary tree so that precise localization of coronary lesions can be made in relation to major branches. The percentage narrowing of the vessel, the length of the lesion, and diameter of the distal coronary vessel can be measured. Collateral vessels, coronary artery bypass grafts, and coronary artery spasm are recorded. The system is simple to use and useful for routine clinical reporting and for detailed analysis of coronary lesions.
