Abstract

The muscle bridge is an anomaly which is found in 0.5-2.5% of coronary angiography examinations and may lead to impairment of coronary blood flow. The clinical course of the disease may be heterogeneous – from completely asymptomatic to the development of myocardial infarction or severe ventricular arrhythmia. We present three patients with muscle bridge in the left anterior descending artery. The clinical course of the disease was different in each patient – from mild symptoms to cardiac arrest during exercise test.
