Abstract

A man of 64 was admitted for the investigation of post infarction angina. He was found to have angiographically normal coronary arteries, except for the presence of a muscle bridge in the left anterior descending coronary artery, believed to be subtending the ischaemic area. He had sustained a completed myocardial infarction in this territory 8 months before with identical findings at coronary angiography. A coronary stent was implanted in the intramyocardial segment and the patient made a good recovery with no adverse events at follow up 6 months later.
