A 22-month-old boy with subaortic stenosis was found to have relatively mature mitral valve tissue beneath the aortic valve, associated with a hypertrophic and prominent interventricular septum. This tissue caused obstruction of the left ventricular outflow tract and resulted in a pressure gradient of 70 mmHg between the aorta and the left ventricle. Surgical treatment was successfully performed to excise the tissue and part of the hypertrophic ventricular septum. Results of microscopic examination of the resected specimen are shown and discussed.
一名患有主动脉瓣下狭窄的22个月大男孩被发现主动脉瓣下方有相对成熟的二尖瓣组织，伴有肥厚且突出的室间隔。该组织导致左心室流出道梗阻，造成主动脉与左心室之间70毫米汞柱的压力阶差。成功实施了手术治疗，切除该组织及部分肥厚的室间隔。展示并讨论了切除标本的显微镜检查结果。
