What happened ?

The patient had an urgent echo which showed no significant regional wall motion abnormality or pericardial effusion. 

He was investigated and treated for potential sepsis, malignancy, auto-immune disease and vasculitis. Further investigation revealed an OM1 stenosis but this was not felt to be a culprit lesion.

The final diagnosis was one of pneumonia with SIRS and a myo-pericarditis.
