We report 2 cases of Myocardial Bridge (MB). MB, even though a very frequent anomaly (found out in 85% of autopsies), often is asymptomatic. It is hard to diagnose in patients affected by coronary artery disease, seldomly found out on selective coronary angiograms (in 16-20% of chest pain cases). MB can be considered as one of the causes of coronary artery disease.
