The electrocardiogram showed sinus rhythm with biphasic T wave on precordial derivations and negative T wave in leads DI and aVL (Figure 1 A). Coronary angiography revealed that myocardial bridging was confined to the left anterior descending artery (LAD) with severe systolic compression (90%) (Figures 1 B, C).
