Key result
LAD myocardial bridging links to recurrent spontaneous ventricular fibrillation and ischemia in a young patient.
Why the study?
Systolic compression of a coronary artery is generally considered benign, but its association with sudden death or ischemia in some patients remains unclear.

Myocardial bridging may trigger VF and ischemia in select patients without other findings; hypothesis-generating and should not yet change practice.
Systolic compression of a coronary artery is considered to be a benign phenomenon, although numerous case reports have suggested an association between bridging and sudden death or ischemia in certain patients without other abnormalities on cardiovascular evaluation. We present the case of a young patient with two episodes of spontaneous ventricular fibrillation and electrocardiographic evidence of ischemia, whose only primary abnormality on extensive workup was a long segment of left anterior descending systolic compression. This case adds to the growing body of anecdotal evidence that myocardial bridging may be associated with significant cardiac events.

Cutler et al. (1997) conducted a case report in Myocardial bridging and ventricular fibrillation (n=1). Myocardial bridging was evaluated on Spontaneous ventricular fibrillation and ischemia. Myocardial bridging of the left anterior descending artery was the sole primary abnormality in a young patient presenting with 2 episodes of spontaneous ventricular fibrillation and ischemia.
