Implication

3D-echo may refine LA assessment clinically; leaves open outcome validation versus 2D in larger cohorts.

Structured PICO

Does 3D-echocardiographic assessment of left atrial active emptying correlate with left ventricular diastolic dysfunction?

Population

56 subjects, including patients with normal LV diastolic function (n=30, mean age 52 ± 15 years, BMI 24.7 ± 2.6 kg/m2) and patients with suspected diastolic dysfunction (n=26, mean age 65 ± 9 years, BMI 26.7 ± 3.7 kg/m2).

Intervention

3D-echocardiographic analysis of left atrial volume and function using newly designed software for passive and active LA emptying

Comparator

Comparison between patients with normal diastolic function and suspected diastolic dysfunction

Outcome

Left atrial active emptying volumes (active atrial stroke volume and True-EF) and their association with LV filling pressure (E/e' mean)surrogate

3D-echocardiographic assessment reveals that left ventricular diastolic dysfunction is associated with a significant reduction in active left atrial emptying, which correlates strongly with LV filling pressures.
