Stentless porcine bioprostheses in the treatment of aortic valve infective endocarditis.
Between January 1992 and June 1994, 23 patients underwent surgery for aortic valve endocarditis at the Department of Cardiovascular Surgery of the University of Verona; a subgroup of 10 patients underwent aortic valve replacement with a porcine stentless valve (Biocor LTDA n = 8; Toronto SPV n = 2). There were 7 males and 3 females with a mean age of 56.3 years (range, 36 to 73 years). Eight patients had active endocarditis and two had healed endocarditis. Nine patients had native valve in endocarditis, the presence of a bicuspid aortic valve in 2, and 1 patient had recurrent prosthetic valve endocarditis (PVE), 7 of whom were in New York Heart Association (NYHA) Functional Class IV. The main indications for operation were congestive cardiac failure, active sepsis, and presence of large and mobile vegetations by echo and arrhythmias. There were no operative or late mortalities in this subgroup of patients. Short-term survival is 100% at a mean follow-up time of 11.2 months (range, 4 to 18 months), with no recurrent endocarditis or valve-related complications.
