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.
一名有不稳定型心绞痛病史的59岁男性被诊断为左前降支（LAD）心肌桥和心尖变异型肥厚型心肌病（AHCM）。他接受了心肌桥松解术和左心室心尖肌切除术。术中，使用心外膜超声识别LAD收缩期受压的心肌桥，并在术后确认这种压迫已解除。此外，心外膜超声用于指导减压心脏的心尖切除程度。术中的心外膜超声这种新用途有助于术前指导外科医生，并在手术后立即确认结果。
