Sudden death in patients with LEOPARD syndrome

LEOPARD or Moynahan syndrome, also called multiple lentigines, is a rare genetic disease which causes multiple visceral abnormalities, including heart abnormalities, and may trigger sudden death. The case of a 26-year-old woman with a history of hypertrophic cardiomyopathy since early childhood is reported. She was referred to consultation due to loss of consciousness, associated with moderate exertion, and a resuscitated sudden death episode. The study revealed the presence of LEOPARD syndrome with subvalvular pulmonary stenosis and left ventricular hypertrophic cardiomyopathy, both of which cause sudden cardiac death.
