Abstract
Left atrial (LA) myxomas are benign neoplasms that are rare in children. Their presentation is dependent on size and location. We describe a seven-year-old girl who was admitted with chest pain, upper respiratory symptoms, and persistent troponin elevation with suspected myocarditis. Workup revealed an infarction from a LA myxoma which embolized to her right coronary artery-posterior lateral branch (PLB). She underwent prompt successful surgical excision of the myxoma. We elected not to perform a coronary artery embolectomy and her infarction was managed medically. We describe this unique clinical scenario and the decision-making process leading to a successful outcome.
左心房（LA）肌瘤是儿童罕见的良性肿瘤。其表现取决于肿瘤的大小和位置。我们描述了一名因胸痛、上呼吸道症状和肌钙蛋白持续升高而入院的七岁女孩，她被怀疑患有心肌炎。检查结果显示，她的右冠状动脉后外侧支（PLB）发生了 LA 肌瘤栓塞引起的梗死。她迅速接受了手术，成功切除了肌瘤。我们决定不进行冠状动脉栓塞切除术，并对她的梗塞进行了药物治疗。我们描述了这一独特的临床情况以及取得成功结果的决策过程。
