Myocardial bridging alone can cause myocardial infarction even in the absence of critical coronary artery stenosis.
Reports a case of myocardial infarction caused solely by myocardial bridging.
May prompt evaluation for myocardial bridging in unexplained MI; hypothesis-generating and should not yet change practice.
Myocardial bridging (MB) is characterised by a segment of a major epicardial coronary artery tunnelling through the myocardium, which is a frequent congenital anomaly, detected in 15–85% of autopsy series and in 0.5–33% of angiographic studies.[1,2][1] MB without critical stenosis is generally
