Full textObjective: Ideal prosthetic heart valve is not available. The use of the patient own pericardium for construction heart valve prosthesis is an interesting alternative and has several potential advantages. The aim of our study is to set up a new method for pericardium preparation with polysaccharide hydrogel and standardize the valve treatment processing and implantation.Méthods: Eighteen sheep underwent aortic valve replacement with autologous pericardium valve traited with polymeric gel or glutaraldéhyde using cardio-pulmonary bypass. The pericardial prosthesis was implanted with a proximal running 5/0 Prolène sutures placed along the aortic annulus and utilization of specially designed instruments. Survival sheep were euthanized after 12 months for histologic evaluation of the pericardial valvular implant.Results: Cardiopulmonary bypass and cross-clamp mean time was 136.17 +/- 27.46 mn and 85.61 +/- 12.21mn respectively. The prosthesis mean time construction was 15.68 +/- 4.84 mn. The mean transvalvular gradient after implantation was 4,1mmHg. The autologous pericardial valves treated with glutaraldehyde tended to show more extensive calcification than pericardial valves treated with polymeric gel.Conclusion: Truly stenless aortic valve replacement using autologous pericardium is feasible with cross clamping time acceptable and technically reliable with the use of specially designed instruments. The use of polymeric gel for treatment of autologous pericardial valve is less aggressive than glutaraldéhyde

Full textThe aortic valvular performance (either of a native valve or a prosthetic valve) is currently and efficiently assessed through clinical indices. These indices are estimated by performing velocity measurements based on Doppler echocardiographic methods. But in the presence of a relevant narrowing in the left ventricle outflow tract, called subaortic stenosis (SAS), it is often difficult or impossible to adequately assess the haemodynamic performance of the aortic valve with the use of the conventional Doppler echocardiographic indices. The aim of the work is to find out why the clinical indices fail when a SAS is present, through relevant experimental and numerical models. The second aim is to implement numerical fluid-structure interaction that exists between the valve and the blood flow. A first 2D numerical fluid-structure interaction model and then a 3D one are developed with the commercial CFD software Fluent. An external program is used to manage a sub-iteration loop ensuring a strong coupling between the fluid and the structure. An experimental model, that is equivalent to the numerical one as far as the geometries and the hydrodynamic conditions are concerned is used to validate the numerical simulation. The validation is performed through the comparison of the velocity fields that are obtained numerically on the one hand and experimentally by Particle Image Velocimetry (PIV) on the other hand. The quantitative and qualitative comparisons between healthy (without SAS) and pathological (with SAS) cases underline the failure that exists in the clinical diagnosis of the valvular performance in the presence of a SAS: the velocities and by consequence the clinical indices are not correlated to the valvular performance. A last theorical model was developed. It is based on the modelisation of potential flow around an airfoil of finite span. Each leaflet of the prosthetic valve is assimilated to an airfoil of finite span. This last model could improve the clinical indices and consequently could bring out changes in the clinical diagnosis of the haemodynamic valvular performance

Full textPercutaneous valve implantation (PVI) is a new with fast growing expansion procedure. Nevertheless, this promising technic has some reefs. Impairment of the implanted device at deployment is one of them. Valvular implantation in dilated right ventricular outflow tract (RVOT) is another limit of the procedure. In our work, we studied the valvular traumatism after prosthesis deployment. Subsequently, we evaluated a new device for RVOT size reduction, in order to widen PVI indications.Firstly, We compared 2 types of valved-stent (VS) (balloon expandable and self-expandable). We compared the occurrence of valvular leaflets injury after crimping and deployment of both types of prosthesis. We showed the occurrence of pericardial leaflet injuries, induced by devices crimping. Otherwise, the presence of sharp histologic lesions with balloon expandable VS, suggests a prosthesis expansion role, in genesis of valvular injuries, as well. We couldn’t show any impairment of valvular tissue mechanical properties after leaflets crimping and deployment. In another part of our work, experimental asymmetric enlargement of the RVOT with creation of severe pulmonary regurgitation, were performed in an ovine model. Size reduction of the enlarged RVOT and PVI were successfully achieved through an endovascular and right transventricular access. Valve function was satisfactory in all correctly implanted VS (one case of inversion). No migration or fractures of the size reducer or VS were seen before animal sacrifice, after 2 months follow-up. Since feasibility of RVOT enlargement and RVOT reduction has been demonstrated, a long-term study is necessary before considering a human implantation. At last but not least, deterioration on valvular leaflets after prosthesis handling is an effect to consider. Taking into account its potential impact on prosthesis durability, it requires further deep investigations
