Abstract Background Despite constant improvement and refinement of the prostheses, the decision between mechanical and biological valves for aortic valve replacement is still controversial. Objective To compare outcomes of aortic valve replacement with bioprosthesis and mechanical prosthesis. Methods This was an observational, historical cohort study with review of medical records. A total of 202 patients who underwent heart valve replacement surgery between 2004 and 2008 were selected, with a mean follow-up of 10 years. The level of significance set at […]

Heart valve disease currently occupies the spotlight in cardiovascular medicine due to recent advances in imaging techniques and emerging therapeutic possibilities, attracting the attention of physicians, researchers, device manufacturers, and investors. Brazil has a prominent international role in the history and technological development of prosthetic heart valves used to treat this disease. The first worldwide implantation of a commercially available porcine valve bioprosthesis occurred in October 1968. About half a century later, in September 2019, passes on the physician and […]
