BUSTAMANTE, John; ECHEVERRI, Claudia E  e  VALBUENA, Javier. Hydromechanical evaluation of bovine jugular veins fixed in glutaldehyde for its use as cardiovascular implant. Rev. Col. Cardiol. [online]. 2007, vol.14, n.4, pp.238-246. ISSN 0120-5633.

Many congenital heart diseases may be treated surgically with biological or artificial implants that will allow the restoration of cardiovascular system functionality. Due to its properties, the biologic implants obtained from dead donors (homografts) are the most appropriate for ventricular output reconstructive surgeries. Unfortunately, these are difficult to acquire, because they are obtained from newborn donors and may be correlated to the dimensions and geometry of the native structure to be repaired. This project evaluated the hydrodynamic behavior of valvular segments of bovine jugular veins (obtained from the Livestock Central in Medellin), mounting the venous segment on a test bank that simulated the right ventricle output tract and the pulmonary trunk, in order to analyze its behavior in similar conditions to those that the vessel must face as bio-implant in the correction of congenital cardiovascular alterations in newborns and infants.

Palavras-chave : bovine jugular veins; valvular bio-implants; vascular biomechanics; pulsatile flow; biomechanical tester.
