Atrial myxoma is the most common primary cardiac tumor. Patients with atrial myxoma typically present with obstructive, embolic, or systemic symptoms; asymptomatic presentation is very rare. To our knowledge, isolated association of atrial myxoma with hypertrophic cardiomyopathy has been reported only once in the English-language medical literature. We report the case of an asymptomatic 71-year-old woman with known hypertrophic cardiomyopathy in whom a left atrial mass was incidentally identified on cardiac magnetic resonance images. After surgical excision of the mass and partial excision of the left atrial septum, histopathologic analysis confirmed the diagnosis of atrial myxoma. The patient was placed on preventive implantable cardioverter-defibrillator therapy and remained asymptomatic. The management of asymptomatic cardiac myxoma is a topic of debate, because no reports definitively favor either conservative or surgical measures.
心房黏液瘤是最常见的原发性心脏肿瘤。心房黏液瘤患者通常表现为梗阻性、栓塞性或全身性症状；无症状表现非常罕见。据我们所知，心房黏液瘤与肥厚型心肌病的孤立关联在英文医学文献中仅被报道过一次。我们报告了一例71岁无症状女性病例，该女性已知患有肥厚型心肌病，在心脏磁共振成像中偶然发现左心房肿块。在对肿块进行手术切除并部分切除左心房隔膜后，组织病理学分析证实为心房黏液瘤。该患者接受了预防性植入式心脏复律除颤器治疗，仍无症状。无症状心脏黏液瘤的管理是一个有争议的话题，因为没有报告明确支持保守或手术措施。
