Myocardial abscess perforation is an extremely rare complication of infective endocarditis. We present a case of a 12-month-old infant who developed community-associated methicillin-resistant Staphylococcus aureus bacteremia after an incision and drainage of a skin abscess. He subsequently developed septic emboli to the brain and lungs, and a myocardial cavity in the outlet portion of the interventricular septum. The cavity ruptured 4 days after diagnosis and created a left ventricle to pulmonary artery fistulous communication. The patient died secondary to embolic complications to the brain. We are not aware of any other cases of myocardial abscess rupture in this location of the heart, in a patient of this age, or due to infection with community-associated methicillin-resistant S aureus .
心肌脓肿穿孔是感染性心内膜炎的一种极罕见并发症。我们报告了 1 例 12 月龄婴儿，该婴儿在脓肿切开引流术后发生社区相关性耐甲氧西林金黄色葡萄球菌菌血症，继而出现脑和肺的脓毒性栓子，以及室间隔出口部分的心肌腔。在诊断后 4 天，该腔破裂，导致左心室至肺动脉瘘道沟通。患者因脑部栓塞并发症而死亡。我们尚未发现任何其他病例在该年龄的患者中，或因感染社区相关性耐甲氧西林金黄色葡萄球菌而导致该部位的心肌脓肿破裂。
