- W2769184259 abstract "Heart valve replacement with a bioprosthesis is one of the most frequently performed procedures in cardiac surgery and represents a highly effective therapy to relieve diseased heart valves. Nevertheless, as postoperatively elevated transvalvular gradients and prosthesis–patient mismatch are reported as shortcomings of the procedure or of the currently used devices, there is a need for novel bioprostheses with improved haemodynamics. This study presents preclinical haemodynamic results after mitral valve replacement with the novel TRIBIO bioprosthesis (TRIBIO) compared with an established bioprosthesis in a sheep model. Six female sheep had their mitral valves replaced with the TRIBIO and 3 with the Carpentier-Edwards Perimount, both sized 19 mm. The TRIBIO consists of a flexible valve-bearing crown, a force-decoupled interface and an intra-annular base ring. Mean and peak transvalvular gradients as well as an effective orifice area were monitored in both groups using transthoracic echocardiography over the course of the 90-day study. In both groups, haemodynamic performance diminished over time. The TRIBIO demonstrated overall superior haemodynamics, i.e. lower transvalvular gradients and a larger effective orifice area, although the results were not statistically significant. On Day 90, the mean values for the mean and peak transvalvular gradients and the effective orifice area were 6 mmHg, 10.2 mmHg and 1.2 cm2 for the TRIBIO and 10 mmHg, 15.8 mmHg and 0.8 cm2 for the Carpentier-Edwards Perimount, respectively. This study demonstrates a trend towards improved preclinical haemodynamic performance following mitral valve replacement with the TRIBIO compared to that with an established bioprosthesis in a sheep model." @default.
