title: Angiographic and surgical aspects of compressive muscular bridges and intramyocardial paths of the anterior interventricular artery (based on 12 cases).
abstract: The authors report 12 cases of myocardial bridges over the anterior interventricular artery discovered surgically. In 5 the compressive myocardial bridges were limited; in 7 the intramyocardial course of the anterior ventricular artery was discovered at operation. Comparison of the operative appearances with the angiographic findings affords a basis for anatomico-radiologic correlation. The authors stress the difference in frequency and significance between the compressive myocardial bridge (an indication for surgery) and the intramyocardial anterior interventricular artery discovered by chance during a procedure for coronary revascularization indicated for stenosing atherosclerotic lesions.
