  • Clinical Outcomes of Tricuspid Annuloplasty Using a C-type Ring Made of Autologous Pericardium

    Abstract: Objective To evaluate clinical outcomes of tricuspid annuloplasty using a C-type ring made of autologous pericardium for the treatment of functional tricuspid regurgitation (TR). Methods Eleven patients underwent tricuspid annuloplasty in Guizhou Provincial People’s Hospital between March 2009 and January 2011, including 5 male patients and 6 female patients with their age of 32-57 (43.80±12.20) years. There were 3 patients with mild TR, 7 patients with moderate TR, and 1 patient with severe TR. Concomitant procedures included mitral valve replacement and/or aortic valve replacement and/or left atrial thrombectomy. The C-type ring was created using a strip of pericardium after 0.8% glutaraldehyde fixation for 15 minutes. Interrupted horizontal mattress suture was used to secure the C-type ring to the tricuspid annulus. Hear function and echocardiography were examined during follow-up. Results There was no in-hospital death, and the hospital stay was 15-28 (21.10±3.80) days. All the patients were followed up for 8-28 (18.50±7.00)months. There was no death or reoperation because of TR or tricuspid stenosis during follow-up. Ten patients had TR during follow-up, including 9 patients with mild TR and 1 patient with mild to moderate TR, but there was no patient with severe TR. The degree of TR during follow-up was significantly reduced than preoperative degree (Z =-2.81,P<0.05). Preoperative and postoperative right ventricular dimension (19.95±5.11 mm vs. 21.57±12.81 mm,P=0.705) and right atrial dimension(37.55±6.79 mm vs. 35.55±5.22 mm,P=0.317)were not statistically different. Conclusion Tricuspid annuloplasty using a C-type ring made of autologous pericardium has satisfactory clinical outcomes for patients with functional TR.
