A heart of stone: a case of acute development of cardiac calcification and hemodynamic collapse.

Acute cardiac calcification is a clinical entity that may develop over days to months and is usually localized to areas of healed myocardial infarction, cardiac surgery or trauma. We present an unusual case of rapidly developing non-ischemic cardiac calcification in the setting of sepsis and end stage renal disease resulting in acute diastolic dysfunction and cardiac collapse diagnosed by computed tomography (CT) and confirmed by autopsy. We propose that dedicated cardiac CT may provide the most accurate means to detect cardiac calcification.
