  • Values are mean (SD).

  • AR, aortic regurgitation; ΔEF, change in ejection fraction on follow up; FS, fractional shortening; LV, left ventricular; LVIDD, left ventricular internal diameter in diastole; LVIDS, left ventricular internal diameter in systole; METs, metabolic equivalents on exercise; RPP, rate–pressure product.
