Introduction and objectives: There is little data available for Spain on the outcomes of surgical treatment for severe tricuspid regurgitation. The aim of this study was to analyze clinical and echocardiographic outcomes in a series of patients who received surgical treatment for severe tricuspid regurgitation and to compare outcomes according to the operative approach to valve repair or replacement.
Methods: Retrospective study in 119 consecutive patients with severe tricuspid regurgitation undergoing valve surgery between April 1996 and February 2010.
Results: A total of 61 ringless and 23 ring annuloplasties were performed and 11 bioprostheses and 24 mechanical prostheses were implanted. Perioperative mortality was 18.5% and was associated with age and cardiopulmonary bypass time. During clinical follow-up (median, 41 [interquartile range, 24-89] months), 2 reoperations were required in the ring annuloplasty and mechanical prosthesis groups; prosthetic thrombosis was diagnosed in 4 patients in the latter group. Total mortality after follow-up was 29.9% and was associated with age>70 years and extracorporeal circulation time. The emergence of new severe tricuspid regurgitation was associated with age and ringless annuloplasty (P=.04).
Conclusions: Ringless repair was significantly associated with recurrence of severe tricuspid regurgitation. The use of mechanical prostheses was associated with a high rate of thrombosis. No significant differences in perioperative or total mortality were found between the different methods used for repair or valve replacement.
