[Coronary artery bypass grafting in a patient after percutaneous left main angioplasty with DES stent implantation].

We present surgical treatment of acute coronary syndrome due to the left main stenosis in a patient in whom 6 months earlier percutaneous left main angioplasty with DES-stent implantation was performed. We discuss indications for percutaneous angioplasty and for coronary artery bypass grafting in patients with left main stenosis.
