Abstract

Microvascular obstruction is a transient phenomenon of "no reflow" after myocardial infarction or radiofrequency ablation, diagnosed using late gadolinium enhancement cardiac MRI. We present a patient with a persistent microvascular obstruction-like lesion following radiofrequency ventricular tachycardia ablation post-myocardial infarction, which was best characterized by a novel dark-blood late gadolinium enhancement technique.

摘要

微血管阻塞是心肌梗死或射频消融后出现的一种短暂的“无复流”现象，可通过延迟钆增强心脏磁共振成像进行诊断。我们报告了一名心肌梗死后行射频消融治疗室性心动过速后出现持续性微血管阻塞样病变的患者，该病变通过一种新型的黑血延迟钆增强技术得到了最佳表征。
