title: [Myocardial bridges. Incidence and relation to some certain coronary variables].
abstract: 72 human hearts from necropsies of subjects with an age range from 27 to 83 years have been examined by dissection. The aim of this study was to know the percentage of myocardial bridges (intramural coronary arteries) and to compare with other studies carried on this subject, using the same or different techniques. Myocardial bridges were observed in 25% of cases. The main localization was the middle third of the anterior interventricular artery. The principal characteristics of the myocardial bridges were: The length, from 4 mm to 25 mm, and the thickness, from 0.3 mm to 1.7 mm. Chi-square test have been made in order to verify the relation between the coronary arterial preponderance and the incidence of myocardial bridges, showing the absence of statistical significance.
