TCT-103 Wire Location by IVUS Strongly Predicts Procedural Success in the Retrograde Approach for Chronic Total Occlusions

During retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI), antegrade wire (AW) and retrograde wire (RW) locations are important. A total of 182 CTO lesions were treated with an intravascular ultrasound (IVUS)–guided retrograde approach at 3 centers in Japan, China,
