Novel approach to stenting the left anterior descending coronary artery through a retrograde approach via the left internal mammary artery graft in a patient with occlusion of the coronary ostium from a prior aortic valve replacement.

ABSTRACT

Total occlusion of both coronary ostia is a rare and potentially life-threatening complication following surgical aortic valve replacement. This report presents a case of a patient with known total occlusion of both coronary artery ostia following combined coronary artery bypass graft surgery and aortic valve replacement who underwent successful percutaneous coronary intervention through a retrograde approach.
