Abstract:
OBJECTIVE:To summarize the clinical application of bioprosthetic valve replacement.
METHODS:Fifty two patients, aged 13-73(52.4+/-14.0) years, underwent cardiac valve replacement with biovalves from June 2002 to June 2006 in our hospital. Fifty three tissue valve replacements combined with 8 mechanical valve replacements were performed. Other procedures were also carried out if appropriate, including bidirectional Glenn shunt in 1 patient with double outlet of right ventricle and pulmonary artery stenosis; interruption of accessory pathway in 1 patient with Wolff-Parkinson-White syndrome; coronary artery bypass graft in 5 with severe coronary artery disease; and atrial or ventricular repair in 4 with congenital septum defects.
RESULTS:One patient died in hospital due to multiple organ failure. The hospital mortality rate was 1.9%. The mean follow-up was 25 months. Two patients lost follow-up and the follow-up rate was 96%. Forty one patients returned to NYHA class I, 9 to class II, and 1 to class III. Echocardiography showed the implanted bioprosthesis functioned well without stenosis or regurgitation. There was no structural deterioration with freedom from thromboembolism and anticoagulant hemorrhage in all patients.
CONCLUSION:The efficacy of biovalves in heart valve replacement is satisfactory.
