Laser angioplasty in a right coronary artery stent restenosis with the guidance of left internal mammary artery contrast injection: case report.

A 43-years-old male who underwent right coronary artery stent implantation 6 months ago presented with total occlusion of right coronary artery at proximal part of the stent without antegrade flow. We successfully used the left internal mammary artery contrast injections for guidance in all stages of the right coronary laser angioplasty intervention.
