The aim was to investigate the effects of balloon dilation of congenital valvar aortic (Ao) stenosis on heart function with conventional and with new echocardiographic techniques. Nine patients, preballoon and 1 to 4 d postballoon dilation of Ao-valve, were included in the study. Assessment of heart function was made by using conventional echo/Doppler, tissue Doppler imaging (TDI) and strain rate imaging (SRI). Mean (and standard deviation) of posttreatment drop of aortic valve pressure gradient was 34.1 (sd 14.0) mmHg, p
