Papillary muscle rupture is a serious mechanical complication of acute myocardial infarction typically seen within 5–7 days following transmural ST‐elevation myocardial infarction. The incidence of papillary muscle rupture has markedly decreased in the modern era due to improved diagnosis and early coronary revascularization of ST‐elevation myocardial infarction. As a result, papillary muscle rupture is increasingly seen following non‐ST‐elevation myocardial infarction where both diagnosis and revascularization can be delayed. In this report, we describe two cases of papillary muscle rupture following delayed presentation of non‐ST‐elevation myocardial infarction and delayed recognition of papillary muscle rupture.
