The retrograde technique for recanalization of chronic total occlusions: a step-by-step approach.
Chronic total occlusion recanalization still represents the final frontier in percutaneous coronary intervention. Retrograde chronic total occlusion recanalization has recently become an essential complement to the classical antegrade approach. In experienced hands, the retrograde technique currently has a high success rate with a low complication profile, despite frequent utilization in the most anatomically and clinically complex patients. Since its initial description, important changes have occurred that make the technique faster and more successful. We propose a step-by-step approach of the technique as practiced at experienced centers in North America. Because the technique can vary substantially, we describe the different alternatives to each step and offer what we perceived to be the most efficient techniques.
