Onyx aortic valve gradients
WebIt is well recognised that high transvalvular pressure gradients can be detected immediately after implantation of a prosthetic aortic valve (AV) which may be due to multifactorial confounding variables, including functional phenomena, pressure recovery and prosthesis-patient mismatch. WebElevation in mean transvalvular gradient is a finding that has a variety of etiologies. One such etiology is the pressure-recovery (PR) phenomenon, a consequence of stream convergence and energy conversion across a narrowing, which is an artifact of Doppler echocardiographic calculations of valvular flow.

Three-dimensional (3D) echocardiography is more precise and reproducible for measuring the mitral valve area since it allows guidance to …
WebOur aim was to compare invasive gradients between valve types for similarly sized valves. Patients who underwent transcatheter aortic valve replacement (TAVR) at the Malcom Randall Veterans Affairs Medical Center and the Bern University Hospital were considered for this analysis. WebDoppler derived mean gradient for St Jude mitral prosthesis was 3.5 mm Hg and for St Jude aortic prosthesis was 10.2 mm Hg. Conclusions: These can be used as reference gradients to assess St Jude prosthetic valve function in patients who did not have early postoperative doppler assessment. MeSH terms Adult
