title: Retrograde recanalization of an in-stent ostial chronically occluded right coronary artery.
abstract: We describe a case of a chronic proximal in-stent CTO extending up to the ostium of a right coronary artery where successful achievement of guidewire passage through the CTO was performed with a retrograde approach. Guidewire trapping into the right guiding catheter was performed thereafter and procedure was completed by retrograde balloon crossing and antegrade stenting.
