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.
