Rupture of mitral valve papillary muscle: a rare complication following myocardial infarction

Here we present a rare clinical presentation of papillary muscle rupture in a 55-year-old man who presented to accident and emergency department with chest pain and was diagnosed as having had a non-ST elevation myocardial infarction. During the admission, he developed papillary muscle rupture due to the myocardial infarction resulting in acute mitral regurgitation. This caused significant haemodynamic compromise needing emergency admission to the intensive care unit and eventually surgery to replace the valve.
