Conclusion:
In young patients with exertional chest pain, myocardial bridging should
be considered in the differential diagnosis. While many patients with
myocardial bridge respond well to medical therapy, those who do not
should explore surgical options for symptomatic improvement and
treatment.
The surgical management of a symptomatic patient with an isolated
myocardial bridge is debated. CABG has been performed, however concerns
regarding graft patency in the setting of non-obstructive CAD is
warranted. Unroofing of the bridge has been described and performed in
case reports throughout the literature, however post-operative
symptomatic improvement and angiographic demonstration of complete
bridge relief have been infrequently reported. Here, we describe a
patient with a symptomatic myocardial bridge involving the LAD for which
medical therapy was ineffective. Our patient underwent successful
surgical unroofing of a long segment myocardial bridge, leading to total
symptomatic improvement and complete resolution on post-operative
coronary angiography.
Multi-institutional registries and randomized clinical trials are
warranted to shed light on optimal strategies for patients with
myocardial bridging refractory to medical therapy.
