Long-term Doppler echocardiographic results of aortic or mitral valve replacement with Biocor porcine bioprosthesis.

OBJECTIVES Our objectives were to evaluate the long-term bioprosthetic and cardiac functional outcome after insertion (over a 10-year period) of a new-generation porcine zero pressure-fixed Biocor bioprosthesis, as well as to determine the echocardiographic accuracy for selection of patients requiring reoperation. The long-term systematic Doppler… (More)
