Retrograde Approach to Coronary Chronic Total Occlusion Intervention: An Update

Chronic total occlusion recanalization remains the final frontier in percutaneous coronary intervention.Retrograde recanalization represents one of the most significant advances in this field and has recently emerged as a vital complement to the classical antegrade approach.It achieves a high success rate with a low complication profile, even in the most complex patients.Since its initial description, multiple refinements have been introduced, making the technique safer, faster, and more effective.
