Myocardial bridges and left coronary arterytrifurcation: a case report

ABSTRACT

During the performance of an angiotecnich in a human heart, to highlight the coronary circulation, weobserved the presence of myocardial bridges in the anterior and medial branches of the left coronary artery, inthis heart was also demonstrated the presence of an artery trifurcation left coronary branches that originatedthe anterior interventricular, circumflex and median. Myocardial bridges are intriguing entities that do notalways show signs and symptoms, the presence of the median artery in hearts with myocardial bridges, is oneof the factors that may explain the absence of signs and symptoms in some patients with this entity. Moreoverthe myocardial bridges can explain the signs and symptoms of ischemia on functional testing.
