Figure 2 Coronary angiography. (A) Severe (approximately 90%) proximal left anterior descending (LAD) artery stenosis with Thrombolysis in Myocardial Infarction (TIMI) grade II flow before intervention. (B) Final angiogram after balloon predilation, drug-eluting stent implantation, and postdilation demonstrating TIMI grade III flow without clinically significant residual stenosis. Yellow arrows indicate the culprit proximal LAD lesion before percutaneous coronary intervention and the treated proximal LAD segment after percutaneous coronary intervention. Both panels are original clinical images from this case and have not been previously published.
