Long-term doppler echocardiographic results of aortic or mitral valve replacement with biocor porcine bioprosthesis

Abstract

These findings suggest that, during a long-term follow-up, most bioprostheses function normally, facilitating improved heart function. Abnormalities in a bioprosthesis usually develop gradually, enabling their detection by Doppler echocardiographic evaluations performed regularly or in case of any symptomatic deterioration.
