Diagnosis of unicommissural unicuspid aortic valve stenosis by different imaging modalities.

A 32-year-old woman was admitted to our institution for further evaluation of aortic stenosis. Diagnosis of severe aortic stenosis was made by transthoracic echocardiography. Transesophageal echocardiography, live three-dimensional echocardiography and cardiovascular MRI allowed precise evaluation of valve morphology. Interestingly, valve morphology was unicuspid unicommissural with a posterior funnel-shaped valve opening. Surgical inspection during valve replacement confirmed the diagnosis of an unicuspid aortic valve. This case report highlights the use of different imaging modalities in characterizing aortic valve morphology.
