At baseline, the mechanical valve group tended to be younger (55.7 vs 65.2) and had less aortic stenois (82.4% vs 89.5%), but ...
They include analysis of mitral, LV outflow tract, and aortic blood flow velocity ... from continuous-wave spectral Doppler recordings of mitral regurgitation. [59] This methodology involves ...
Concomitant valvular lesions including aortic insufficiency and mitral regurgitation can be evaluated. Measuring the maximum blood flow velocity by continuous-wave Doppler from different windows ...
