• W2020384975 abstract "Background Aortic valve regurgitation (AR) in the pediatric population has increased in recent years because of the expanded use of new surgical and hemodynamic procedures. Unlike adult patients, few predictors for the need of operation have been proposed in young asymptomatic or mildly symptomatic patients with AR. Methods To unmask early abnormalities of left ventricular (LV) function, 59 participants were enrolled: 14 asymptomatic patients (mean age 18 years) with congenital isolated severe AR and normal LV function (LV ejection fraction > 50%); and 45 healthy control subjects with comparable age and body surface area. All the studied population underwent standard echocardiographic examination, integrated backscatter, and strain rate imaging study. Results Conventional echocardiographic indices of global LV systolic performance for patients with AR were similar to that of control subjects. Compared with control subjects, integrated backscatter analysis demonstrated a significant reduction in cyclic variation in both septal and posterior walls (P < .05). LV radial and longitudinal deformation properties for patients with AR were significantly reduced (P < .05) as assessed by peak systolic strain rate. Conclusion Our results demonstrated the ability of integrated backscatter and strain rate imaging to detect early subclinical abnormalities in young patients with severe congenital AR despite the presence of a normal ejection fraction.
