Choosing the optimal aortic valve prosthesis for middle-aged patients ... valve replacement provides reduced residual transvalvular gradients and improvement in left ventricular reverse remodeling ...

An echocardiogram shows normal systolic function and a heavily calcified aortic valve. The patient's peak Doppler transvalvular gradient is ... deterioration of the prosthetic valve, requiring ...

Prosthesis-patient mismatch (PPM ... In terms of hemodynamics, mean aortic valve gradients were lower in patients with small and medium annuli undergoing TAVR versus surgery at all time points up to 2 ...

Transcatheter aortic-valve replacement (TAVR ... was deployed within the original prosthesis (Figure 1). After the procedure, the transaortic mean pressure gradient was 14 mm Hg, which was ...

CHICAGO, IL—Patients undergoing TAVR with a self-expanding supra-annular bioprothesis (CoreValve, Evolut R, or Evolut PRO; Medtronic) have lower aortic valve mean pressure gradients, larger effective ...

The surgical arm had increasing rates of prosthesis-patient mismatch ... significant between-group differences in mean gradient, aortic valve area, and Doppler velocity index at 30 days, they ...

The CoreValve prosthesis consists of a self expandable ... EOA increased significantly after TAVI (p<0,0001). Peak and mean aortic valve gradients decreased significantly after TAVI (p<0,0001).

Mean aortic valve gradients were higher after ViV TAVR than after native TAVR (16 mm Hg vs 9 mm Hg; P < .001) and highest for patients with a smaller prosthesis. In a related editorial ...

Better hemodynamic (blood flow) performance for TAVR with statistically significantly lower mean aortic valve gradient (9.0 mm ... two years were reported. The prosthesis-patient mismatch was ...

WASHINGTON (May 16, 2016) --Patients with a combination of left ventricular dysfunction and low aortic valve gradient, or reduced force of blood flow through the aortic valve, have higher ...
