All continuous variables reported as mean (SD). AV indicates aortic valve; EDD, end‐diastolic dimension; ESD, end‐systolic dimension; LA, left atrium; LV, left ventricle; LV‐GLS, left ventricular global longitudinal strain; LVOT, left ventricular outflow tract; LV‐SVI, left ventricular stroke volume index; RVSP, right ventricular systolic pressure.
