Tricuspid valve repair using autologous pericardium annuloplasty in adults

Uncorrected functional tricuspid regurgitation can lead to long-term morbidity and mortality. To evaluate our results using autologous pericardium annuloplasty to treat tricuspid regurgitation, we retrospectively reviewed 59 consecutive adult patients aged 19 years to 83 years (58.7 +/- 15.5 years) who underwent tricuspid valve annuloplasty between 2000 and 2003. Concomitant procedures consisted of mitral valve surgery in 83% of patients, aortic valve surgery in 28%, coronary bypass in 31%, and atrial-septal defect correction in 28%. Annuloplasty was performed using a strip of pericardium treated in glutaraldehyde 0.6% for 10 min. Two rows of continuous horizontal mattress Gore-Tex sutures were used to secure the pericardium to the tricuspid annulus. Follow-up was performed in 100% of the patients, and the mean follow-up was 4.4 +/- 1.2 years (range, 2.4 to 7 years). Postoperative death within 30 days occurred in 1 of 59 patients (1.6%). None of the patients required reoperation related to tricuspid regurgitation or stenosis. The actuarial survival rate was 98.4% at 7 years after operation. Echocardiography was performed in 58 of 58 surviving patients (100%). Up to 7 years postoperatively, tricuspid regurgitation was trace in 67.2% of patients, mild in 31%, and moderate in 1.8%; there was no occurrence of severe regurgitation on follow-up. Our results indicate that autologous pericardium tricuspid annuloplasty is a useful procedure in patients with moderate or severe tricuspid regurgitation. This procedure provides a durable, reproducible annuloplasty of the tricuspid valve.
