- Experimental Study of Bileaflet Mechanical Heart Valves(2022) SALES, Eraldo; MAZZETTO, M.; BACHT, S.; CESTARI, I. A.Biological or mechanical heart valve prostheses are used as a treatment to replace failing native heart valves. The goal of this study is to investigate the hydrodynamic performance of small sizes bileaflet mechanical heart valves (BMHVs) considering their use to control flow direction on a pulsatile pediatric ventricular assist device (VAD) [1]. Small size BMHVs of 17, 19 mm were tested in vitro and compared to 23 mm prosthesis. Each prosthesis was placed on a pulse duplicator (4-90 bpm, 2.0-4.0 L/min flow range) and pressure and flow signals were recorded to determine pressure gradient, flow regurgitation and effective orifice area (EOA). Pressure gradients (maximum/minimum; mmHg) were (12.2/8.5), (8.4/6.3) and (8.2/5.8), for 17, 19 and 23-mm, respectively. Valve effective orifice areas (maximum/minimum; cm 2 ) were (1.05/1.02), (1.37/1.24) and (1.55/1.35) for 17, 19 and 23-mm sizes, respectively. The regurgitation fractions (maximum/minimum; %) obtained were (6.91/5.29), (10.47/6.08), and (14.63/10.04), for 17, 19 and 23-mm sizes, respectively. The results suggest that the mechanical valves have adequate performance according to the requirements of the ISO 5840:2015 standards and that they can be used to effectively control flow direction on a pediatric pulsatile ventricular assist device.
- 14 Years of History on Sustainability: Waste Management FMUSP/IMT/SVOC(2018) MARQUES, Fabio Luiz Navarro; SARAIVA, Arlete Araujo; CHAVES, Adilson Caetano Cesario; SILVA, Ana Maria Goncalves da; KANASHIRO, Edite Hatsumi Yamashiro; POMPEU, Eduardo; SIQUEIRA, Gabriela Hase; BERNARDO, Joana Sueli Maziero; APOLINARIO, Lilian; SANCHEZ, Maria Carmen Arroyo; GUIMARAES, Maria Ines Calil Cury; MAUAD, Thais; SOUZA, Felipe Neme; AULER JR., Jose Otavio CostaHigh regulation in environmental protection and sustainability was established in Brazil around 2003. From that time, the board of directors of the Faculty of Medicine, Tropical Medicine Institute, Death Verification Service, and Medical Investigation Laboratories, of the University of Sao Paulo created the Waste Management Committee to organize and implement actions to comply with Brazilian legislation. This paper outlines the main actions taken by the Committee and Board of directors of the institutions, presenting it in ages. During the first five years were developed works to know the passive/regular discharge of infectious agents, chemicals, radioactive compounds, recyclable and common garbage. From this data, were constructed stations for provisory disposal, transportation flow and general rules were established, and training was given to staff and students. During the following five years, or in the second phase of actions plans, efforts were focused on improving the management of the process and increasing the gathering of recyclable materials. Now, in the third phase, actions have been developed aiming to eliminate devices that use mercury and mercury vapor lamps from FMUSP building; furthermore, composting of food and garden material is in the evaluation process. These actions gave to FMUSP two Prize Friend of the Environment (2010 and 2016), offered by Health Secretary of Sao Paulo State, and these experience will be shared in this paper. However, it is necessary to have in mind that this work was done under Brazilian regulations, but certainly, it can be adjusted to all countries.
