Use of the retrograde approach for preserving the distal bifurcation after antegrade crossing of a right coronary artery chronic total occlusion.

Percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) can be challenging when a bifurcation is present at the distal cap. We describe a case of combined use of the antegrade and retrograde approach for preserving a distal cap bifurcation during CTO PCI.
