Spontaneous Aortic Cusp Rupture Associated with Valvular Myxomatous Transformation

Abstract
Two adult male patients are presented with sudden onset of aortic incompetence secondary to rupture of an aortic valve cusp. Histological examination of these leaflets revealed myxomatous changes. Operation was undertaken on both patients, and an aortic homograft valve was inserted in each with a very satisfactory result. The relationship between medionecrosis of the aorta and myxomatous valvular transformation is discussed.
