Application value of magnetic resonance imaging in patients with apical hypertrophy cardiomyopathy

  • 摘要: 目的 评价心脏磁共振在心尖肥厚型心肌病诊断方面的临床应用价值。 方法 回顾性分析2017~2018年在我院就诊的9例心尖肥厚型心肌病患者,所有患者均行心脏磁共振检查,观察心肌受累节段,测量心肌厚度、心室心房容积、左心室射血分数,评价心肌首过灌注及延迟强化特点。 结果 9例患者心脏磁共振表现为左心室心尖部心肌肥厚,符合心尖肥厚型心肌病诊断标准。分析磁共振图像特点,将患者分为单纯型和混合型。其中单纯型心尖肥厚型心肌病6例,混合型心尖肥厚型心肌病3例。3例可见心尖室壁瘤。8例出现延迟强化,表现为肥厚的心肌内斑片样、点灶样强化。其中5例单纯型延迟强化范围局限在心尖部,3例混合型延迟强化范围累及左室中部、甚至乳头肌。 结论 心脏磁共振一站式成像对于诊断心尖肥厚型心肌病有独特作用,磁共振对比剂延迟强化,提示心肌纤维化,对临床治疗和预后有指导意义。
