title: [Myocardial bridging and sudden death].
abstract: Myocardial bridging (MB) has been described more than 200 years ago. However it's implications on the genesis of myocardial ischaemia were not studied until recently. Little is known about the real incidence, survival in people with this entity and pathophysiology. Data found in the literature are prone to bias since all studies published are retrospective and the populations studied are limited and very selectioned. Most authors agree that most MB is rather frequent and seldom generates ischaemia. A significant clinical effect of myocardial bridging implies a thick MB with at least 75% coronary systolic obstruction associated with ventricular hypertrophy and/or rapid tachycardia. In the peculiar case of sudden death, we think that to consider MB as a cause of this sudden death we need more than a simple necroptic finding of a MB. A history of clinical and/or electrocardiographic confirmed ischaemia or the presence of histological abnormalities suggesting myocardial ischaemia can be helpful.
