Right atrial function evaluation is increasingly important in aging populations and those with pulmonary hypertension, with 3D echocardiography and MRI being preferred over 2D echocardiography.
L.H.B. Baur (2008) conducted an editorial in Pulmonary arterial hypertension. Age and pulmonary arterial hypertension vs. Healthy younger individuals was evaluated on Right atrial passive and active emptying volumes and fractions. Right atrial passive emptying volume and fraction decrease with age, while active emptying volume and fraction increase with age, with further impairment seen in patients with pulmonary arterial hypertension.
