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.
