Epicardial ultrasound in a case of myocardial bridge and apical hypertrophic cardiomyopathy

Abstract

A 59‐year‐old male with a history of unstable angina was diagnosed with a myocardial bridge of the left anterior descending artery (LAD) and apical variant hypertrophic cardiomyopathy (AHCM). He underwent unroofing of the myocardial bridge and a left ventricular apical myectomy. Intraoperatively, epicardial ultrasound was used to identify the myocardial bridge with systolic compression of the LAD and confirm resolution of this compression postoperatively. Furthermore, epicardial ultrasound was used for guiding the degree of apical resection of the decompressed heart. This novel use of intraoperative epicardial ultrasound can help guide surgeons preoperatively and confirm results immediately after an operation.
