Key result
Anatomic reconstruction using a right internal mammary artery patch successfully restored patency of an isolated ostial left main coronary artery stenosis in a single patient.
Why the study?
Surgical patch angioplasty is an alternative to classic coronary artery bypass grafting for patients with isolated coronary ostial stenosis and normal distal coronary arteries.
Does surgical patch angioplasty using a right internal mammary artery patch restore patency in patients with isolated left main coronary artery ostial stenosis?

Does surgical patch angioplasty using a right internal mammary artery patch restore patency in patients with isolated left main coronary artery ostial stenosis?
Suggests right internal mammary artery patch angioplasty is a feasible alternative to CABG for isolated.
Surgical patch angioplasty is an alternative to classic coronary artery bypass grafting for patients with isolated coronary ostial stenosis and normal distal coronary arteries. We present a case where we successfully used an arterial patch from the right internal mammary artery to restore patency of an isolated ostial left main coronary artery stenosis. This technique is likely to offer more physiological antegrade myocardial perfusion, mimic normal vascular anatomy, and may be associated with an improved outcome.
