title: Unicuspid aortic valve presenting with cardiac arrest in an adolescent.
abstract: Unicuspid aortic valve (UAV) is a rare congenital anomaly typically affecting patients in their fourth and fifth decades and presenting with signs of heart failure. Our case is one of a previously asymptomatic teenage girl with a UAV, who presented with cardiac arrest and was successfully treated. Only two other similar cases have been reported in the literature, both were of slightly older male patients. Our case highlights the morbidity associated with the anomaly supporting the need for careful assessment of the valve in cases where UAV is suspected.
