On-x 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. WebProcedural success, defined as having a normally functioning valve in the proper anatomical location, was achieved in 150 patients (99.3%). The mean transprosthetic gradient was 13.4 ± 5.0 mm Hg, and 23 patients (15.2%) showed a gradient of 20 mm Hg or more at discharge or at the 1-month follow-up.
