Abstract:Background: Isovolumic myocardial acceleration (IVA) is a new tissue Doppler parameter in the assessment of systolic function of both right and left ventricles. It remains unaffected with the changes in pre-and after load with in the physiological range. With the advent of newer parameter like IVA, better assessment are naturally expected. Thus it creates a fertile ground where upon many studies are being done as it chosen here. The aim of study was to assess the effect of MS severety on LV systolic function u… Show more
