A 72-year-old Japanese woman with systemic sclerosis was admitted to our hospital because of symptoms of heart failure. Cardiovascular magnetic resonance (CMR) imaging had shown that extensive myocardial fibrosis secondary to systemic sclerosis was the main cause of heart failure. One month after CMR, she had complete atrioventricular (AV) block. It was suggested that the progression of fibrosis to the AV node caused complete AV block. This case report has clinical implications in highlighting the fact that CMR is useful for not only evaluating the present pathophysiology but also predicting future adverse events in patients with systemic sclerosis.
一位 72 岁的日本系统性硬化症女性患者因心力衰竭症状被收入我院。心血管磁共振（CMR）成像显示，广泛的心肌纤维化是心力衰竭的主要原因。CMR 后 1 个月，患者出现完全性房室（AV）阻滞。提示纤维化向 AV 结进展导致完全性 AV 阻滞。该病例报告具有临床意义，突出了 CMR 不仅可用于评估当前病理生理学，还可预测系统性硬化症患者未来不良事件的发生这一事实。
