To evaluate the diagnostic accuracy of the echocardiographic aortic leaflet eccentricity index in identifying bicuspid aortic valves compared to angiographic, surgical, or pathological findings.
Recorded aortic root echocardiograms from N=89 patients with aortic valve anatomy verified by selective angiography, surgical inspection, or autopsy.
Measured the eccentricity index (E.I.) of aortic leaflets at the onset of diastole, defining an E.I. ≥ 1.3 as abnormal.
An abnormal E.I. (≥ 1.3) occurred in 74% (23 of 31) of patients with isolated nonobstructed or mildly obstructed bicuspid aortic valves, whereas all 14 patients with normal tricuspid valves displayed central echoes (E.I. 1.0 to 1.25).
False-positive abnormal E.I. findings occurred in 6 of 21 patients with ventricular septal defects (VSD), predominantly associated with high membranous VSD and aortic valve prolapse.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Observational study reveals that diastolic eccentricity index identifies bicuspid aortic valves in patients without ventricular septal defects, highlighting its noninvasive diagnostic utility.
