The electrocardiogram (ECG) demonstrated a wide-QRS-complex tachycardia compatible with a sustained monomorphic ventricular tachycardia (VT), which terminated spontaneously (Fig. 1). Coronary angiography showed remarkable coronary compression in the middle segment of the left anterior descending artery (mid-LAD) during the systolic cardiac phase without significant coronary artery disease, indicating myocardial bridging (MB) (Fig. 2 and Video 1).
(A) Coronary angiography in the posteroanterior cranial projection during systole (arrows). (B) Coronary angiography in the posteroanterior cranial projection during diastole.. Video 1. Coronary angiography in the posteroanterior cranial projection during diastole and systole. There is dynamic compression of the midportion of the left anterior descending artery during systole.
