Key result
Retrograde PCI via LIMA graft successfully treats total occlusion of both coronary ostia.
Why the study?
Total occlusion of both coronary ostia is a rare and potentially life-threatening complication following surgical aortic valve replacement.
Case Report (n=1)
Demonstrates the feasibility of a retrograde approach via the left internal mammary artery graft for stenting the left anterior descending coronary artery in a patient with total occlusion of both coronary ostia post-aortic valve replacement.

May support retrograde LIMA access in rare ostial occlusions; hypothesis-generating and should not yet change practice.
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.

Soud et al. (2023) conducted a case report in Total occlusion of both coronary ostia following CABG and AVR (n=1). Percutaneous coronary intervention through a retrograde approach via the left internal mammary artery graft was evaluated on Successful percutaneous coronary intervention. Percutaneous coronary intervention through a retrograde approach via the left internal mammary artery graft was successfully performed in a patient with total occlusion of both coronary ostia.
