Percutaneous coronary intervention for chronic total occlusive lesion of a left anterior descending artery using the retrograde approach via a septal-septal channel.
The retrograde approach is an effective therapeutic strategy for chronic total occlusion (CTO) intervention. In CTO cases, the retrograde approach from the opposite coronary artery is not always applicable. In certain left anterior descending (LAD) CTO cases, the distal LAD is filled from the septal channel where it is supplied by the proximal septal route. We report two LAD CTO cases of percutaneous coronary intervention (PCI) conducted with a wire from the proximal septal branch to the distal septal channel using the retrograde approach.
