title: [Aortic insufficiency due to quadricuspid aortic valve].
abstract: In a 45 year old patient with clinic diagnosis of aortic regurgitation the two-dimensional echocardiography demonstrated a quadricuspid aortic valve and severe aortic regurgitation by Doppler. The quadricuspid aortic valve is a rare pathology, usually not associated with other cardiovascular pathologies and in which there is evolution with aortic regurgitation due to malposition of the four cusps.
