Iteration of Reverse Controlled Antegrade and Retrograde Tracking for Coronary Chronic Total Occlusion Intervention: a Current Appraisal

Coronary chronic total occlusion (CTO) remains one of the most challenging subsets for percutaneous coronary intervention (PCI). The retrograde recanalization is one of the most significant amendments of the technique that remains critical to improved success of CTO PCI. Currently the reverse controlled antegrade and retrograde tracking (CART) is the most dominant retrograde technique. With emergence of new equipment and important iterations, this approach has become safer, faster and more successful. In this review, the author proposes the iteration and standardization of this technique which would further facilitates its adoption with more efficacy and safety.
