Intramyocardial bridges are a coronary circulation anomaly. They usually occur on the path of the anterior descending artery and are classified as superficial or deep. During a routine autopsy, we found and report an intramyocardial bridge in large part of the right coronary artery pathway, including the sinoatrial and posterior descending branch. The patient did not show signs of coronary insufficiency, and died from an acute respiratory failure caused by aspiration pneumonia. Due to the infrequency of cases of intramyocardial bridges of the right coronary artery without concomitant clinical symptoms or signs, we conducted a literature review in this regard.
