Multivalvular surgery for infective endocarditis.

The short and the long-term results of our experience with 25 consecutive patients who underwent multivalvular surgery for infective endocarditis are analysed. Preoperatively, 20/25 (80%) patients were in New York Heart Association (NYHA) stage III or IV, and 2/25 (8%) patients were in cardiogenic shock. All the diseased valves were replaced with mechanical bileaflet prosthesis except seven mitral valves and one tricuspid valve, which could be repaired. Major postoperative complications occurred in 3/25 (12%) patients: a fatal cerebral haemorrhage, a reversible cerebellar syndrome and an intractable heart failure, which required transplantation. During a mean follow-up of 4.7 years (range 6 months to 16.8 years), 7/25 (28%) patients suffered from valve-related complications: five bleedings (one died), one embolic event and one prosthetic valve thrombosis. The actuarial freedom of valve-related event at 10 years was 61.8 +/- 12.4%. There was no prosthetic endocarditis. At follow-up, 20/21 (95%) survivors were in NYHA stage I or II. Long-term outcome in our patient population operated on for multivalvular endocarditis, is satisfactory with no recurrent infection and excellent functional results.
