51 DES usage in challenging lesions is associated with favorable early and mid- term results in most cases Notable exceptions may be safenous vein grafts and diabetic patients (the latter applies to sirolimus-eluting stents only) Lesion preparation and accurate choice of the most appropriate platform-drug combination for each individual lesion are also pivotal to maximize success and long- term efficacy
