Válvula aórtica cuadricúspide: una revisión de la literatura

The quadricuspid aortic valve (QAV) is a rare congenital heart defect characterized by the presence of 4 cusps in the aortic valve structure. It is frequently associated with other congenital heart defects. Patients are usually asymptomatic, but when this condition is associated with functional disorders such as aortic regurgitation or stenosis, clinical manifestations are evident. The final diagnosis is made using different cardiac imaging techniques such as echocardiography, cardiac tomography, and nuclear magnetic resonance.

The treatment of this condition depends on the functionality of the aortic valve, and accordingly will be the indication for surgical treatment. The prognosis is generally favorable and depends on the functional compromise of the valve.
