Myocardial Bridging

 These are slices of a coronary artery. Do you see the abnormality? . . . . This is what's known as myocardial bridging or tunneling. It's present at birth. Normally the coronary arteries live in the fat layer above the heart muscle. When they tunnel into the muscle like this, it can be problematic during times of exertion because the muscle constricts the artery, limiting bloodflow to the heart. Some people with mild tunneling have no symptoms, but others can't exercise or have shortness of breath when doing so. Some people oddly find these symtoms go away with exercise. It's different for every person. This anomaly is present in about about 30% of autopsies and may be a cause of sudden death, especially if exertion was involved.
