Abstract：
Midventricular obstruction (MVO) is a rare form of hypertrophic cardiomyopathy (HCM). While surgical treatment for HCM is among the most technically challenging cardiac operations for acquired disease, surgery for MVO is rarely reported. A 38-year-old man was admitted to our hospital with a cough and dyspnea. Transthoracic and transesophageal echography and computed tomography revealed extensive left ventricular hypertrophy, extending from the anteroseptal wall to the apex, and marked papillary muscle hypertrophy. We underwent septal myectomy via aortotomy (Morrow procedure) and apical surgery. Extended myectomy provides the best exposure to the hypertrophied septum and improves the functional status of patients.
摘要：
中室梗阻（MVO）是一种罕见的肥厚型心肌病（HCM）。虽然HCM的手术治疗是获得性疾病技术上最具挑战性的心脏手术之一，MVO手术很少报道。一名38岁男子因咳嗽和呼吸困难入院。经胸和经食道回波描记术和计算机断层扫描显示广泛的左心室肥厚，从前间隔壁延伸到顶点，和明显的乳头状肌肥大。我们通过主动脉切开术（Morrow程序）和根尖手术进行了间隔肌切除术。扩大的肌切除术提供了对肥大的隔膜的最佳暴露，并改善了患者的功能状态。
