Introduction
Papillary muscle rupture (PMR) is one of the most serious mechanical complications of acute myocardial infarction, with an incidence of 0.5-5% (1). Some reports of PMR not related with ischemic failure include idiopathic, infectious or connective tissue disorder etiologies (2), including Takotsubo disease (3,4). In this paper, we present a case of non-ischemic spontaneous PMR, potentially related with extreme physical activity.
