[Surgery of valve replacement with pericardial prosthesis].
The ideal artificial heart valve still does not exist among the various cardiac valves available to the clinician. Morbidity and mortality are directly related to the valve itself. Despite the promising hemodynamic results obtained in the 70s with pericardial prosthesis, these valves were progressively abandoned due to their poor long-term resistance. Based on an analysis of the causes of failures, modifications were made in the manufacturing method and current results with pericardial valves has greatly improved, inciting new interest in their clinical use. Today, the pericardium is recognized as a valid substitution material for bioprostheses. Results of long-term series should confirm current studies. Research is under way to determine how to improve pericardium longevity since tissue deterioration remains the limiting factor.
