Dr. Khaldoon Alaswad presents a case of flush ostial right coronary artery occlusion due to instent restenosis. Primary retrograde crossing was attempted, but penetration into the aorta was very challenging. Using electrocautery over the retrograde guidewire the lesion was modified sufficiently to allow retrograde CTO crossing, followed by snaring, externalization and successful completion of the case, partially "crushing" the prior stent.
