Does the myocardial bridge protect the coronary from atherosclerosis? A comparison between the branches of the dual-left anterior descending coronary artery type 3: An autopsy study

► We compared the atherosclerotic changes in short and long branch of dual LAD type 3. ► Both branches are exposed quite equally to all factors for atherosclerosis. ► Difference in atherosclerosis depends only on the presence of a myocardial bridge. ► This difference increased with the age of the deceased. ► Atherosclerosis is less prominent in intramyocardial course of long branch.
