Article 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.
