摘　　要：1病例资料患者,男,50岁,主因"反复胸闷、心悸5年,再发1d"于2019年12月5日入院。患者5年前无明显诱因出现心悸,感心跳加快,伴胸闷,持续数分钟后自行缓解,无胸痛,无头晕、黑朦及晕厥,无夜间阵发性呼吸困难及双下肢水肿等不适。6个月前患者于当地医院行冠状动脉(冠脉)造影后诊断"冠心病"(单支血管病变,未行支架植入),予抗血小板聚集、调脂稳定斑块、降低心肌氧耗等治疗后症状好转出院。This article reports a case of hypertrophic obstructive cardiomyopathy. This patient was treated by radiofrequency ablation under the guidance of three-dimensional intracardiac echocardiography. The patient’s symptoms were significantly relieved after radiofrequency ablation. Besides, the blood flow velocity and peak pressure difference in the left ventricular outflow tract were remarkably decreased. We report this case to analyze the etiology, symptoms, examination, and treatment methods and explore the feasibility and advantages of three-dimensional intracardiac ultrasound-guided radiofrequency ablation in the treatment of hypertrophic obstructive cardiomyopathy.
