Abstract
Complex lesion angioplasty, such as chronic total occlusions, coronary vessels with right angle take-offs, tortuous vessels, and tortuous internal mammary artery or saphenous vein grafts is a continuing challenge. The complex problems have been successfully managed with novel guiding catheter shapes and ultralow profile balloons. However, on occasion steerable guidewire placement remains extremely difficult, despite significantly improved means of intracoronary manipulations.
