Over the last 10 years considerable interest has been paid in the angiographic recognition of successful percutaneous transluminal coronary artery angioplasty (PTCA), complication of the technique, and angiographic predictors of restenosis. This report summarizes various angiographic patterns visualized at the site of angioplasty and correlates these patterns with morphologic findings. Of 66 patients undergoing PTCA for chronic or unstable angina pectoris, 76 PTCA sites were available for analysis. The two most common angiographic patterns at the angioplasty site (intimal flap=43%, intraluminal haziness=38%) correlated morphologically with intimal‐medial splits with localized dissections (79%). Shallow, superficial intimal lesions, laminated thrombus, and adventitial tears accounted for the remaining morphologic changes. Eight PTCA sites without morphologic injury corresponded to smooth wall changes and spasm at angiography.
