Intraoperative coronary angiography and fractional flow reserve measurement with dobutamine infusion in supra-arterial myotomy for a myocardial bridge: a case report.

ABSTRACT:

Background

A myocardial bridge (MB) is a congenital coronary anomaly, wherein the epicardial coronary artery tunnels through the myocardial band. Treatment is indicated when clinical symptoms occur, and β-blockers are the first choice of treatment. Symptomatic patients refractory to medical therapy are considered for other options, including stent placement, coronary artery bypass grafting, or surgical supra-arterial myotomy. Supra-arterial myotomy is effective; however, the symptoms might persist if myocardial resection is inadequately performed.

Case summary

We encountered a patient experiencing exertional chest pain. Coronary angiography revealed a MB at the mid-left anterior descending artery with systolic compression. The patient's fractional flow reserves (FFRs) were 0
