*
Indicates variables entered into logistic regression.
#
p < 0.05 (non-stenosis group vs. stenosis group).
LVEF — left ventricular ejection fraction; LVEDD — left ventricular end-diastolic dimension; LVESD — left ventricular end-systolic dimension; LAD — left atrial dimension. PAP — pulmonary artery pressure; PPG — transmitral peak pressure gradient
