In heart transplant recipients, the aetiology of coronary vasospasm is largely unknown but it has been reported to be related to coronary vasculopathy or allograft rejection. We report a case of acute, reversible coronary vasospasm which caused malignant arrhythmias in a cardiac transplant recipient one month after transplantation without evidence of coronary vasculopathy or allograft rejection. The patient had a normal post-operative course with no other complications; this case supports the hypothesis that coronary vasospasm is not necessarily related to epicardial coronary artery disease or allograft rejection, but rather may be due to an abnormal reversible vasoreactivity.
