A case of quadricuspid aortic valve characterized by echocardiography and magnetic resonance imaging.

We report a rare subtype of quadricuspid aortic valve (QAV) associated with moderate aortic regurgitation in a 17-year old woman symptomatic for palpitations. The patient was admitted to our department for cardiac evaluation due to a previous diagnosis of bicuspid aortic valve; she underwent a new two-dimensional echocardiography revealing a rare type of quadricuspid aortic valve with a moderate regurgitation. For further investigating potentially associated abnormalities, patient was referred to Cardiac MRI; MRI showed no other abnormalities and confirmed echocardiographic findings.
