We present the case of a 55-year-old lady presenting 5 months after a liver transplant with acute coronary syndrome. She was on maintenance-dose tacrolimus. An angiogram diagnosed a spontaneous coronary artery dissection, which was successfully stented. This is the third case in the literature associating a calcineurin inhibitor with a spontaneous coronary arterial dissection. The detrimental effect of calcineurin inhibitors on vasculature is well recognised. This report highlights their potentially serious side-effects. It should be appreciated that calcineurin inhibitors have the potential to cause or contribute to this rare vascular phenomenon and the diagnosis should therefore be considered in those taking such drugs.
