DOPPLER ECHOCARDIOGRAPHIC OBSERVATON ON IONESCU -SHILEY VALVE IN PATIENTS WITH MVR

Abstract

Follow-up studies were made on 48 cases. Incidence of cuspal thickening was noted on 38%, 61% of cases for 5 and 7 years Max. velocity at the LV inflow tract was 1-1.5m/s so long as the valve was functioning normally. Pressure half time (PHT) was gradualy prolonged year by year. In the patients with stenosis, PHT was prolonged and Max. V was increased. In the patients with regurgitation, PHT was remained within normal rainge while max. V was increased.
