Systemic sclerosis (SSc) is characterized by widespread vascular lesions and skin and internal organs fibrosis, including the heart; all cardiac layers, endocardium, myocardium, and pericardium, may be involved. We report the relevance of cardiac MRI findings in scleroderma patients with cardiac symptoms.
50 patients, all fulfilling the ACR SSc criteria (19 with limited and 31 with diffused skin involvement) were evaluated using a 1.5T MR scanner. Images were acquired before and after contrast medium administration; the exams were considered positive with one or more of these findings: enlarged volumes, reduced EF, regional kinetic anomalies, edema, DE or pericardial effusion.
40 patients (80%) had one or more cardiac abnormalities: 5 patients had myocardial edema; 2 an increased interventricular septum thickness; 22 dilated ventricles or reduced EF; 12 an abnormal regional ventricular motion (2 of these with akinetic segments); 17 a delayed enhancement with different patterns, all without coronary distribution; 22 a pericardial effusion CONCLUSIONS: Pathologic findings were documented in 80% of the cases confirming a high occurrence of abnormal MR data. Myocardial involvement in systemic sclerosis can be assumed by the presence of multiple pathologic MRI findings. CMR seems to be a valuable tool to identify and assess the presence of cardiac involvement.
系统性硬化症(SSc)的特征是广泛的血管病变和皮肤及内脏器官纤维化,包括心脏;所有心脏层、心内膜、心肌和心包都可能受累。我们报告了心脏 MRI 发现与有心脏症状的硬皮病患者的相关性。
50 名患者均符合 ACR SSc 标准(19 名局限性皮肤受累,31 名弥漫性皮肤受累),使用 1.5T MR 扫描仪进行评估。在给予造影剂前后采集图像;如果出现以下一种或多种发现,则认为检查结果为阳性:容积增大、EF 降低、局部运动异常、水肿、DE 或心包积液。
40 名患者(80%)存在一种或多种心脏异常:5 名患者有心肌水肿;2 名患者室间隔增厚;22 名患者心室扩张或 EF 降低;12 名患者出现局部心室运动异常(其中 2 名存在无运动节段);17 名患者出现不同模式的延迟强化,均无冠状动脉分布;22 名患者有心包积液。
80%的病例中均有病理学发现,证实了异常 MR 数据的高发生率。系统性硬化症的心肌受累可通过存在多种病理学 MRI 发现来假设。CMR 似乎是一种识别和评估心脏受累的有价值的工具。
