Table 2.
Findings on index echocardiogram according to major BAV type. Aortic valve function, left ventricular systolic function, and presence of aortic dilatation at any proximal segment on index echocardiogram. Numbers are count (percentage). p values are from the chi-square test. LVEF left ventricular ejection fraction
