Spontaneous papillary muscle rupture (PMR) is a rare cardiovascular emergency. We present a 63-year-old male who presents with acute dyspnea who was found to have an anterior PMR, with no evidence of coronary artery disease, infection, or trauma. A review of cases of nonischemic spontaneous PMR published in 2000-2015 identified 11 additional cases of spontaneous PMR. Posterior and anterior papillary muscles involvement was identified in 54.5% and 45.5% of cases, respectively. Rapid identification due to advances in imaging modalities and improved surgical management has led to optimal outcomes in patients with spontaneous PMR.
自发性乳头肌破裂（PMR）是一种罕见的心血管急症。我们报告一名63岁男性，因急性呼吸困难就诊，经检查发现有前乳头肌破裂，无冠状动脉疾病、感染或外伤证据。回顾2000 - 2015年发表的非缺血性自发性PMR病例，又发现了11例自发性PMR病例。分别有54.5%和45.5%的病例发现后乳头肌和前乳头肌受累。由于成像技术的进步和手术管理的改善，能够快速识别，从而使自发性PMR患者获得了最佳治疗效果。
