The longitudinal right ventricular diameter was moderately correlated with the maximal velocity across the aortic valve (r = 0.38 p < 0.01) and the aortic valve area measured by the continuous equation (r = 0.313 p <0.05), mean gradient pressure van (r=0, 412 p< 0, 01), max gradient pressure (r= 0, 411 p<0, 01).
