BACKGROUND: A recently introduced tricuspid annuloplasty ring, the MC(3) ring, has a 3-dimensional form that is designed to remodel the tricuspid valve annulus. The aim of this study was to investigate its clinical performance. METHODS AND RESULTS: From December 2004 to April 2008, 103 patients underwent tricuspid annuloplasty using the MC(3) ring (mean age, 52+/-13 years; 63.6% women). The average preoperative tricuspid regurgitation (TR) grade was 2.5+/-0.8, and the mean preoperative systolic pulmonary artery pressure was 48.4+/-15.0 (24-88) mmHg; the mean follow-up was 26.7+/-11.2 (0-52) months. One patient died after surgery (1.0%), because of cor pulmonale. No MC(3) ring-related complications, such as, atrioventricular block, ring dehiscence or thromboembolism, were encountered. Predischarge echocardiography showed a significant decrease in the TR grade (2.5+/-0.8 to 0.8+/-0.8, respectively; P<0.001). After a median 15 months, the mean TR grade was stable (0.9+/-0.8). The mean systolic pulmonary artery pressure was also lower than its preoperative value (33.9+/-7.9 vs 48.4+/-15.0 mmHg, respectively; P<0.001). CONCLUSIONS: The MC(3) ring provides good mid-term clinical and echocardiographic results for TR. However, long-term follow-up is mandatory to confirm the stability of this procedure.
