Do Doppler echocardiographic indices derived from tricuspid annular motion accurately assess right ventricular systolic function compared to radionuclide angiography?
Doppler echocardiographic indices derived from tricuspid annular motion correlate well with radionuclide angiography and are useful tools for assessing right ventricular systolic function.
