elective PTCA of totally occluded coronary arteries is feasible but the primary success rate is lower (57%) than that associated with conventional lesions. The long-term clinical results following successful angioplasty are satisfactory (64%), but the inc
Discussion of AVD Asahi, Prowater, and Confianza guidewires in tortuous vessels and resistant coronary arterial occlusions/lesions. Success in opening chronic total occlusions is 50-75%; better guidewires are essential.
Techniques for penetrating chronic total occlusion (CTO) to ensure complete revascularization using percutaneous coronary techniques. Success is only 50–75%, even in the best hands. How to improve?
