Early right coronary vasospasm presenting with malignant arrhythmias in a heart transplantation recipient without allograft vasculopathy.
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.
