Aortic valve regurgitation due to cusp aneurysm: a case report.

Two-dimensional echocardiography is a valuable tool in visualizing and monitoring aortic valve and root abnormalities. We present a rare case of a patient with massive aortic regurgitation due to cusp aneurysm, which was accurately diagnosed by echocardiography and treated by valve replacement. A complicated course with recurrent aneurysms of the aortic wall after aortic valve replacement was remarkable in this case. Although different possible etiologies could not be determined, endocarditis and/or aortitis may be the most likely explanation of the complicated and finally fatal course of this patient.
