title: Quadricuspid pulmonary valve associated with atrial septal defects and pulmonary stenosis.
abstract: A 1-month-old Hispanic female was referred to the cardiology service. During physical examination, a systolic ejection murmur at the pulmonic area was auscultated. The echocardiography evaluation of the pulmonary valve demonstrated a quadricuspid pulmonary valve (QPV) with slightly thickened leaflets, associated atrial septal defects and mild pulmonary stenosis. QPV is a rare congenital anomaly variant that can remain asymptomatic with few or non-hemodynamic alterations. Associations with structural or functional alterations have been reported. This is the first case of QPV that was diagnosed in a Hispanic newborn.
