In this report, we describe complete disappearance of LBBB with normalization of LV function in two patients with cardiac sarcoidosis (CS) after immunosuppressive therapy. Both of these patients were ideal Class IA candidates for CRT (Complete LBBB, QRS ≥ 150 ms, EF < 30%). If CS is identified early, immunosuppressive treatment can lead to not only improvement of left ventricular function but also disappearance of the left bundle branch block. Timely diagnosis and management of CS obviated the need of CRT in these patients. It may be reasonable to evaluate all non-ischemic cardiomyopathies for underlying reversible causes prior to CRT implantation.
在本报告中，我们描述了两例心脏结节病（CS）患者在接受免疫抑制治疗后，左束支传导阻滞（LBBB）完全消失且左心室功能恢复正常。这两名患者均是心脏再同步治疗（CRT）的理想IA类候选者（完全性LBBB，QRS≥150毫秒，射血分数<30%）。如果CS能早期确诊，免疫抑制治疗不仅可改善左心室功能，还能使左束支传导阻滞消失。对CS的及时诊断和处理避免了这些患者接受CRT的必要性。在植入CRT之前，评估所有非缺血性心肌病是否存在潜在可逆病因可能是合理的。
