We present a case of a woman who had acute coronary syndrome caused by myocardial bridge. She was treated with percutaneous coronary intervention and stent implantation. Two months after the procedure the patient had myocardial infarction because of subacute thrombosis and during the second intervention another stent was implanted. After a few months another acute coronary syndrome occurred because of restenosis and balloon angioplasty with stent implantation was performed. Despite this the artery occluded and sufficient collateral circulation was developed. Current opinions concerning percutaneous coronary interventions of myocardial bridges are presented.
