Can isolated myocardial bridging of the left anterior descending coronary artery be associated with sudden death during exercise?

At autopsy, myocardial bridging of the left anterior descending coronary artery was found without any other disease. Whether an isolated myocardial bridge may lead to a fatal cardiac event is a matter to be clarified.
