使用晚期Gd增强心脏磁共振成像(LGE-CMR)的高分辨率疤痕特征对于指导室性心律失常(VA)的治疗是有用的。然而，屏气困难、心律失常和植入型心律转复除颤器(ICD)可能会降低影像研究的质量。我们评价了在VA消融术前LGE-CMR中，左心室(LV)底部至心尖瘢痕的图像质量对解释结果的影响。连续43例接受VA消融的患者接受了梯度回声LGE-CMR检查。在ICD患者中(n = 24例)，宽带反转-恢复抑制了ICD伪影。对于非ICD患者，也可以进行单次激发稳态自由进动LGE-CMR以减少呼吸运动/心律失常伪影。对因心脏/呼吸运动伪影、ICD相关伪影和图像对比度引起的充分/有限的疤痕解释的研究质量进行评估。28%的非ICD患者的研究中，图像质量限制了对至少一张图像的疤痕解读，而ICD患者的这一比例为71%(p = 0.012)。每个ICD患者研究中5个图像切片的质量有限，而每个非ICD患者研究中0个图像。ICD患者的质量较差主要是由于与运动相关的伪影(54%的ICD研究与6%的非ICD研究，p = 0.001)以及与ICD相关的图像伪影(25%的研究)。在合并ICD的VA消融术患者中，传统的CMR方案通常具有有限的疤痕解释的图像切片，这可能会限制对整个心脏疤痕的评估。运动伪影导致图像质量不佳，特别是在ICD患者中。改进的运动和ICD伪影抑制方法可以更好地描绘高分辨率LGE瘢痕特征，以指导VA消融。网上版载有补充材料，可在10.1007/s10554-022-02734-5查阅。
High-resolution scar characterization using late gadolinium enhancement cardiac magnetic resonance imaging (LGE-CMR) is useful for guiding ventricular arrhythmia (VA) treatment. However, imaging study quality may be degraded by breath-holding difficulties, arrhythmias, and implantable cardioverter-defibrillators (ICDs). We evaluated the effect of image quality on left ventricle (LV) base to apex scar interpretation in pre-VA ablation LGE-CMR. 43 consecutive patients referred for VA ablation underwent gradient-recalled-echo LGE-CMR. In ICD patients (n = 24), wide-bandwidth inversion-recovery suppressed ICD artifacts. In non-ICD patients, single-shot steady-state free-precession LGE-CMR could also be performed to reduce respiratory motion/arrhythmia artifacts. Study quality was assessed for adequate/limited scar interpretation due to cardiac/respiratory motion artifacts, ICD-related artifacts, and image contrast. 28% of non-ICD patients had studies where image quality limited scar interpretation in at least one image compared to 71% of ICD patient studies (p = 0.012). A median of five image slices had limited quality per ICD patient study, compared to 0 images per non-ICD patient study. Poorer quality in ICD patients was largely due to motion-related artifacts (54% ICD vs 6% non-ICD studies, p = 0.001) as well as ICD-related image artifacts (25% of studies). In VA ablation patients with ICDs, conventional CMR protocols frequently have image slices with limited scar interpretation, which can limit whole-heart scar assessment. Motion artifacts contribute to suboptimal image quality, particularly in ICD patients. Improved methods for motion and ICD artifact suppression may better delineate high-resolution LGE scar features of interest for guiding VA ablation.
