Abstract:
OBJECTIVE:To meet the treatment requirements for mitral regurgitation disease, this study designed a novel valve repair system and evaluated its hydrodynamic performance.
METHODS:A mitral regurgitation model was created. The valve repair system was loaded onto the regurgitation model, and pulsatile flow tests and steady backflow leakage tests were conducted.
RESULTS:The pulsatile flow test results indicated that the percentage of reflux after product implantation was lower than that before implantation under different concentric outputs and reverse pressures. The average cross-valve pressure difference after implantation was less than 5 mmHg. The steady backflow leakage test results showed that as the reverse pressure increased, the leakage amount of the valve repair system after implantation also increased.
CONCLUSION:The developed valve repair system exhibits excellent hydrodynamic performance, suggesting the feasibility of its application in the treatment of clinical mitral regurgitation.
