Full textThe goal of this work is to develop a textile heartvalve prosthesis concept. Textile material, thanks to its discrete structure, associâtes low bending stiffness with high membrane résistance. Different prototype manufacturing techniques and their constraints are presented. Performances of the obtained prototypes are evaluated in vitro, in terms of static and dynamic régurgitation as well as pressure drop accross the valve. The results bring to the fore which are the textile parameters (weawing, saturation index, filament diameter. . . ) and the manufacturing process that do influence the prosthesis behaviour signlf'icantly. One more aspect of this work is the visualisation of the flow accross the valve (particle image technique) in order to analyse, in a qualitative way, the influence of the textile roughness on the sinus whi'rl formation

Full textThis PhD work is divided into four different parts. the first part concerns the hemodynamic characterization by in-vitro cardiovascular testing of mitral valvular prosthesis from different manufacturers in order to provide reference values for clinical diagnosis. The second part focus on bi leaflet mechanical heart valve in each pressure recovery resulting of flow through the three orifices could lead to an overestimation of transvalvular pressure gradient. This could create ambigious assessment in case of high value of transvalvular pressure gradient. This part aims to quantify this pressure recovery and identify the influence of dysfunction (leaflet obstruction or patient prosthesis mismatch) on this value. Third part consists in valve-in-valve procedure in which a transcatheter valve is impllanted in a failled bioprosthesis. It provides in vitro testing, first globally, of assemblies composed of SAPIEN Edwards prostheses in different manufacturers' bioprosthesis.As highlighted in the previous parts inflows of the mitral prostheses can not be considered as plane and results of left atrium flow patterns. The last part studies the left atrium flow following mitral valve replacement

Full textThis thesis is based on the evaluation studies of an instrumental platform dedicated to video assisted minimally invasive mitral valve surgery, and of the robotic Da Vinci system in LAD bypass with mammary artery in a closed chest approach. 1) Evaluation of Portaclamp. In 20 patients who underwent cardiac surgery with Portaclamp, a clinical study showed that the clamping system is safe, fast and easy and does not generate undue morbidity. In a pig model, severe lesions of the intima were observed on the clamping spot with the endoclamp, in comparison with Portaclamp and Chitwood clamp. 2) Evaluation of Portapleg. Portapleg is an auto-suturing system dedicated to antegrade cardioplegia delivery, and based on a Nitinol clip left implanted on the aorta. In 20 patients, the closure of the puncture aortic hole and the haemostasis after protamine were obtained in all cases. The procedure did not generate undue morbidity and there was no device-related adverse event. 3) Evaluation of Mitrax’s. The Mitrax’s retractor is a pattern cut polymer sheet, self-expanding and auto-adjusting. The effectiveness of Mitrax’s was evaluated in 62 patients who consecutively underwent a video-assisted mitral valve procedure. The global satisfaction index was 4.6±0.5, demonstrating the effectiveness of the device which provides optimal exposure and excellent direct vision. 4) Comparative analysis of minimally invasive techniques for LAD revascularization with mammary artery graft (Port Access, MIDCAB, TECAB). In a prospective study, 160 patients were included. At 3-month postoperatively, the end-point of LAD reintervention were PA-CABG, 0%; MIDCAB, 1.8%; TECAB, 10%; p=0.01. At 3-year, reintervention-free survival was significantly lower in the TECAB group: PA-CABG, 100% ; MIDCAB, 98±5 % ; TECAB, 88±8 % ; p<0.05

Full textValvular heart diseases are important cardiac pathology and valvular heart insufficiency is one of them. The standard treatment is valve replacement with prosthetic valve. Lacks of ideal prosthetic valve and the drawbacks inherent in prosthetic material and anticoagulant therapy, encourage us to develop techniques of conservative surgery of the valve. Today, repair of the aortic valve remains a surgical challenge, but mitral valve repair is frequently possible. However, the result and possibility of repair depends on the mechanism of insufficiency and the extension of the lesion of the mitral valve. For overcoming all these obstacles, we proposed the theory to study of the magnetic forces of permanent magnets as an adjuvant, or as exclusive treatment to restore effective valve coaptation. To realize this idea, we based our research on three steps: 1 - Characterization of magnets required. 2 - Feasibility study of the magnets in vitro and in vivo 3 - Verification of the effectiveness of the magnetic force to achieve the desired coaptation in valvular insufficiency. This research is done in collaboration between the department of Thoracic and Cardiovascular surgery of Pitié-Salpêtrière hospital in Paris and the research group Electrodynamics - GREM3 LAPLACE Laboratory in Toulouse. The magnets were fabricated by taking into account the following factors: lowprofile and permanency; biocompatibility; the conservation of magnetization in a blood medium; mechanical flexibility of the implanted elements; and the possibility of sterilization. One of the main concerns was to elaborate the adapted intensity of the magnetic force, such that it would be sufficiently strong to close the valve, yet be weak enough to allow valve opening during cardiac cycle. To assess the feasibility, before conducting experiments in animals, in vitro data were obtained and judged appropriate by using a circulating pig heart model with a paracorporeal pneumatic (Thoratec®) ventricular assist device. The phase of animal testing was carried out by the establishment of three permanent magnets on the aortic valve in seven sheep kept alive for 3 months and the results were satisfactory: - No iatrogenic prolepses, - Perfect bio-tolerance without the need for anticoagulation - No visible inflammatory reaction at autopsy on the third postoperative month. Finally, to study the effectiveness of the magnetic force to achieve the desired coaptation in valvular insufficiency, three models of magnets have been tested on 4 sheep, but the results were not satisfactory. Currently we try to solve the problem and new magnets are by the way of conception. To our knowledge, the use of magnetic force to correct valvular incompetence has never been reported. Even if the experimental phase of magnets for treating valvular insufficiency has not reached its conclusion, we demonstrated the feasibility of the concept of healthy valve. This field of investigation must continue to be explored because the magnets have several advantages. On the one hand, they are technically easy to perform, and could thus allow a rapid repair. On the other hand, because of this simplicity, we could consider a percutaneous implantation, which will open a new way for conservative surgery in valvular insufficiency
