This case highlights the echocardiographic challenges in distinguishing between aortic vegetation and a flail aortic cusp in patients with severe aortic regurgitation.
Echocardiographic distinction between aortic vegetation and flail cusp remains unreliable in severe AR; this case leaves open the role of multimodality imaging.
A patient with severe aortic regurgitation showed abnormal echoes in the left ventricular outflow tract compatible with aortic vegetation or flail aortic cusp. At operation, a pedunculated vegetation on a prolapsed aortic cusp was found. The case illustrates some of the pitfalls in the echocardiographic distinction of the two conditions.
