Retrograde Percutaneous Intervention of Chronic Total Occlusion Step by Step

Abstract

Abstract Retrograde approach for chronic total occlusion percutaneous intervention is the ultimate technique for success in cases of high Japan-CTO (JCTO) score, ostial locations, long calcific lesions with calcium, and in retry cases. There are various methods of collateral cross, reverse controlled antegrade and retrograde tracking, and externalization, which are practiced by various experts. Intravascular ultrasound-guided procedures will minimize complications and increase chances of stent optimization for better outcomes.
