Movement disorders following heart surgery are very unusual. Post-pump chorea is mainly a pediatric complication of heart surgery, typically manifesting after a latent period of normality and is usually related with long extracorporeal circulation time and deep hypothermia. We report a 73-year-old woman, without risk factors predisposing to paroxysmal movement disorders, presenting acute choreoathetoid movements 5 days after aortic valvular replacement with normal extracorporeal circulation time and perioperative normothermia.
