Abstract
LANZAS RODRIGUEZ, Róger A; ACUNA, Jorge Fernández and MAGANA AGUILAR, Alejandro A. Puente miocárdico con fenómeno de "ordeñamiento" coronario como causa de angina inestable. Rev. costarric. cardiol [online]. 2005, vol.7, n.1, pp.51-54. ISSN 1409-4142.
Myocardial bridges are actually bundles of muscle fibers that cover the path of an epicardial coronary artery for a variable length. Having the patient no symptoms or presenting with an acute coronary syndrome. A coronary angiogram will demonstrate systolic compression of an epicardial artery, which disappears during diastole. This is commonly named "milking phenomenon". We hereby present the case of a male with an acute coronary syndrome who was first seen at the Tony Facio Hospital in Limon. Given his variable EKG changes he was referred to the Calderon Guardia Hospital for coronary angiogram. This exam did show dynamic systolic compression of the left anterior descending coronary artery as a cause of his angina. We believe that this entity should be kept in mind particularly in patients with an acute presentation and variable electrocardiographic findings. A coronary angiogram is of paramount importance to make the diagnosis to establish an adequate treatment.
