AR, aortic regurgitation; AS, aortic stenosis; DD, diastolic dysfunction; LVDd, left ventricular dimension diastole; LVDs, left ventricular dimension systole; LVEDV, left ventricular end‐diastolic volume; LVEF, left ventricular ejection fraction; LVM, left ventricular mass; MR, mitral regurgitation; MS, mitral stenosis; RVSP, right ventricular systolic pressure; TR, tricuspid regurgitation.
Those with P value < 0.05 were in bold which means the variable is significant.
