Two-Year Outcomes of theSirolimus-Eluting Stent According toUnprotected Left Main Lesion

The data of long‐term outcomes of sirolimus‐eluting stent (SES) according to lesion location of unprotected left main coronary artery (LMCA) is scarce.

ANGIOGRAPHIC VERSUS FUNCTIONAL SEVERITY OF CORONARY ARTERY STENOSIS IN ASIANS

Results: Mean % diameter stenosis and lesion length were 59.3±17.0% and 20.9±11.7mm, respectively. 52.6% of the lesions were located in LAD and 48.2%, in proximal segments. 474 lesions (36.4%) were functionally significant. The best cutoff value to determine the functional significance of a stenosis was % diameter stenosis of 55.5%. Its sensitivity, specificity, positive and negative predictive value to predict the functional significance were 67.3, 67.1, 53.9 and 78.2%, respectively. The proportion of functionally significant stenosis in <50%, 50-70% and >70% lesions was 19.2%, 41.3% and 64.8%, respectively (Table).
