The incidence of myocardial bridges in heart transplants.
Coronary angiograms of 64 heart transplant patients were reviewed to determine the incidence of myocardial bridges. In 33% of the patients, myocardial bridges were detected, almost exclusively across the midportion of the left anterior descending coronary artery. The incidence is higher than previously reported in the literature and is thought to be related to increased stiffness and hypertrophy of the myocardium, which facilitates angiographic detection of myocardial bridges in the transplanted heart.
