A 320-slice CT scan successfully identified myocardial bridging in a young athlete presenting with exercise-induced syncope and a Brugada-like ECG pattern.
CT detection of myocardial bridges merits consideration in athletes with exertional syncope and Brugada-like ECG; leaves open causal role and management implications.
A 29-year-old professional athlete was referred for cardiac evaluation after a syncope occurring during strenuous exercise.Twelve-lead ECG showed Brugada-like pattern ( fi gure 1 ), but both fl ecainide and genetic tests were negative. ECG Holter and echocardiogram were normal. ECG stress test showed no signifi cant ST-segment changes. A CT scan showed two typical myocardial bridges of the left anterior descending artery, with intramural tracts of 10 mm in the mid-segment and of 15 mm in the distal segment
