Retrograde-Guided Antegrade Puncture Reentry Technique for Retrograde CTO PCI: Procedural Outcome and Safety Evaluation.
BACKGROUND Improving the efficiency of traversing the occluded segment is important in retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We developed the retrograde-guided antegrade puncture reentry (RPR) technique to improve procedural efficiency while maintaining safety in retrograde...
