A practical technique for accurate and reproducible determination of coronary arterial stenotic lesions has been developed. This technique eliminates the shortcomings of the conventional subjective way of analysis. Its use in appropriate cases with obstructive lesions in the coronary circulation will result into objective angiographic data as a baseline for their possible hemodynamic significance. Comparative studies between the results of angiographic measurements of this type and clinical and hemodynamic data retrieved by other clinical applicable diagnostic methods should increase our understanding of the pathophysiology of the coronary circulation in patients with coronary artery disease.
