Abstract
We present a case of recurrent vasospasm as an uncommon cause of ventricular fibrillation in a young female patient who was found to have a genetic mutation of unknown significance in the desmoplakin (DSP) gene and ultimately required an implantable cardiac defibrillator and percutaneous coronary intervention. Refractory vasospasm as a cause of chest pain and cardiac arrest may be under-recognised. In this manuscript, we highlight the natural history of refractory vasospasm, treatment considerations including medical therapy, implantable cardiac defibrillator and percutaneous coronary intervention. Lastly, we explore the potential correlation between the DSP mutation and her clinical presentation and the growing importance of genetic testing in unexplained cardiac arrest.
