Abstract
Brazil has contributed for the world development of cardiology, especially in the cardiac surgery field. The improvement of surgical techniques makes possible to perform several successful heart transplantations in Brazil. However, the number of cardiac donors is lower than the number of candidates for heart transplantation. Consequently many patients die waiting for an organ. To support those patients, the leading international institutions are developing several different ventricular assist devices (V AD) like artificial ventricles, total artificial hearts, axial pumps and implantable centrifugal pumps. The implantable centrifugal pumps have high durability, more than 2 years. One problem is that the commercially available pulsate VADs are not really available, or even accessible, for Brazilian patients. About 62,000 cardiac surgeries by year are performed in Brazil, 47.000 using extracorporeal circulation. We estimate that 2000 patients could be potential candidates for a VAD implantation. Therefore, became very important to improve the VAD's research areas and develop our own technology with accessible price for Brazilian people. The objective of this project is to improve this research area, studding and developing an implantable centrifugal blood pump for long term ventricular assistance as well its surgical procedures. During the initial phase of tests with the prototypes, functional simulations and in vitro studies will be performed. On the second phase of tests, animal in vivo experiments will be performed. Many multi-disciplinary research groups will participate on this study as well as: physicians, surgeons, veterinarians, mechanical and electronic engineers and biologists, from different institutions as: IDPC, USP, UNICAMP, ITA, USJT and UFMG, making integration work for scientific and technical improvement with high national and international relevancy.
