Circulation:电解剖电位图在心肌内膜活检中的诊断价值

电解剖电位图(EVM)是一种很有前途的心肌内膜活检(EMBs)方法。然而,目前很少有数据支持其可行性和安全性。本研究报告了接受EVM引导的EMBs的最大患者队列,以显示其诊断效果,并将其与心脏磁共振(CMR)引导的方法进行比较。

该队列共纳入了162位患者(2010年-2019年)。在EVM和CMR确认的病理区域进行EMB。根据EMB结果评估CMR和EVM在鉴别心肌病变部位的敏感性和特异性。

ARVC合并心肌炎一例

术前CMR显示有70%的患者有晚期钆增强,而EVM提示有61%的患者存在低压区。右心室(73%)、左心室(19%)或双侧心室(8%)取样。EVM被证明与CMR具有相似的敏感性(74% vs 77%),特异性分别为70%和47%。

嗜酸性心肌炎一例

在12例经EMB证实的心肌病患者中,EVM发现了CMR评估中未发现的病理区域。EVM和CMR合用的灵敏度高达95%。EMB分析使39%的患者明确诊断,与疑诊区分开来。并发症发生率低,大多与血管通路有关,无患者需要紧急处理。

综上,鉴于EVM对心肌病变区域的敏感性和特异性,它被证明是一种很有前途的靶向EMB工具。EVM具有与CMR相似的精确度。EVM联合CMR对EMB的阳性预测值高达89%。

Circulation:定量心肌灌注的预后意义

心肌灌注反映冠状动脉的大血管和微血管循环。近期,使用心血管磁共振进行灌注定量的发展使临床自动测量心肌灌注成为可能。本研究探索了应激心肌血流量(MBF)和心肌灌注储备(MPR)对患者预后的影响。

Circulation:常规进行心脏磁共振对特殊原因心衰患者病因诊断的作用

心脏磁共振(CMR)是一种被推荐用于心衰(HF)患者的影像学检查;但目前尚无证据显示CMR比经胸超声心动图更有益处。研究人员提出这样一个主要假设:常规使用CMR有助于精确诊断非缺血性心力衰竭;和一个次

AIM:心血管磁共振(CMR)可用于疑似冠心病患者的诊断

在相同的疑似冠状动脉心脏疾病(CHD)患者中,在比较心血管磁共振(CMR)和单光子发射计算机断层显像(SPECT)方面还没有前瞻性,预测数据。该研究的目的是建立CMR和SPECT预测主要不良心血管事件(MACEs)的能力。来自英国的研究人员进行了CE-MARC(冠状动脉心脏疾病磁共振成像的临床评价)年度随访研究,对MACEs随访至少5年(心血管死亡,急性冠脉综合征,不定期血运重建或心血管原因住院)
