ABSTRACT
Myocardial bridges are congenital structural abnormalities with debated clinical relevance; they may be traditionally asymptomatic or associated with various clinical manifestations, some of which may be potentially fatal. We report on a 60 years old man, who underwent a follow-up stress/rest myocardial perfusion scintigraphy developing asymptomatic exercise-induced ST-elevation and demonstrating completely reversible ischaemia in the scintigraphic images. Subsequent coronary angiography showed no artery stenosis, but revealed an intramyocardial pathway of the left anterior descending artery throughout a myocardial bridge. In conclusion, to our knowledge, this is the first reported case of asymptomatic exercise-induced ST-elevation secondary to a myocardial bridge.
