This article is a case report of a 56 years old man, without known cardiac abnormality, presented signs of cardiac insufficiency. Transthoracic echocardiography revealed a quadricuspid aortic valve (QAV) with a moderated regurgitation. The clinical treatment was initiated with a good evolution. After one year, a new echocardiography revealed huge aortic regurgitation, pulmonary hypertension and lower ejection fraction. After that, the surgery for changing the valve was indicated in order to prevent the pathology progression. QAV is a rare pathology (0.003% to 0.043%). Usually is not associated with other cardiovascular pathologies. It can be an incidental finding but in general it carries aortic regurgitation in adulthood due to bad closure of the four cusps. There are different anatomical variations for the aortic valve cusps: four unequal cusps, three equal cusps and one smaller cusp (majority) and up to four equal cusps. Transthoracic and transoesophageal echocardiography can easily asses the morphological and functional status of such a valve.
