ABSTRACT

Coronary arteries generally have an epicardial pathway. When they go deep into the thickness of heart muscles they form the so-called muscular bridges or intra-myocardial courses. During systole, these bridges significantly reduce the vessel light and produce a dynamic extrinsic compression, known as milking phenome-non; which appears more frequently in the left anterior descending artery, espe-cially in its mid and distal segments. Although milking may be a rare phenomenon the incidence of intramyocardial course in necropsy samples ranges from 34-52%. Its evolution is quite favorable although, in some patients, its presentation may range from precordial pain to sudden death. Until now, the use of beta-blockers seems to be the most viable therapeutic alternative. The case of a patient with this condition is presented in this article.
