Legionnaires' disease is the designation for pneumonia caused by the Legionella species. Among the rare extrapulmonary manifestations, cardiac involvement is most prevalent, in the forms of myocarditis, pericarditis, postcardiotomy syndrome, and prosthetic valve endocarditis. Mechanical circulatory support has proved to be a safe and effective bridge to myocardial recovery in patients with acute fulminant myocarditis; however, to our knowledge, this support has not been used in infectious myocarditis specifically related to Legionellosis. We describe a case of Legionella myocarditis associated with acute left ventricular dysfunction and repolarization abnormalities in a 48-year-old man. The patient fully recovered after left ventricular unloading with use of a TandemHeart percutaneous ventricular assist device. In addition, we review the English-language medical literature on Legionella myocarditis and focus on cardiac outcomes.
军团病是由军团菌属引起的肺炎的名称。在罕见的肺外表现中，心脏受累最为常见，表现为心肌炎、心包炎、心脏手术后综合征和人工瓣膜心内膜炎。机械循环支持已被证明是急性暴发性心肌炎患者心肌恢复的安全有效桥梁；然而，据我们所知，这种支持尚未用于与军团菌病相关的感染性心肌炎。我们描述了一例48岁男性患者，其患有与急性左心室功能障碍和复极异常相关的军团菌心肌炎。该患者在使用TandemHeart经皮心室辅助装置进行左心室卸载后完全康复。此外，我们回顾了关于军团菌心肌炎的英文医学文献，并重点关注心脏结局。
