Muscle bridges were observed in the majority of cases (32%), but none of these cases presented with signs, symptoms, or complications attributable to this anomaly, for which they were considered benign.
Myocardial bridges were found in 14 hearts (47%); about these, there were in 9 hearts (30%) muscle bridges only above the anterior interventricular artery; in 3 cases (10%) simultaniously over anterior interventricular artery and afluents of the anterior interventricular vein; in 1 heart (3%), it ocurred over left ventricular branches of the posterior interventricular artery and vein and in 1 heart (3%) over anterior ventricular branch of the right coronary artery.
The reported rate of angiographic bridging is less than 5% while rate of muscle bridges is up to 86% in autopsy case studies1,2.
Muscle bridges are more common in men than in women and tend to affect patients in their fourth decade of life (1).
