Less common abnormalities include unicuspid and quadricuspid valves. The latter is a rare finding that is often associated with aortic regurgitation. Congenital aortic valve abnormalities such as this may be missed on standard transthoracic echocardiography (TTE). Advanced imaging modalities, including transesophageal echocardiography (TEE) and magnetic resonance imaging (MRI), are useful in providing detailed anatomical assessment of valve morphology. The following case illustrates the use of TEE in making this diagnosis in a patient with severe aortic regurgitation.
