Assessment of Contributors of Aortopathy and Subclinical Left Ventricular Dysfunction in Normally Functioning Bicuspid Aortic Valves.

Subclinical myocardial dysfunction was observed in BAV patients with normal aortic valve function. LV dysfunction was independent of age, aortic velocity and AA diameter, which suggested the presence of intrinsic myocardial disease. Aging contributes to aortic dilatation in normally functioning BAV.
