Background: Functional tricuspid regurgitation is a challenge regarding indications for repair and proper surgical technique. Aim of the study: We reviewed our midterm results of tricuspid valve repair for functional regurgitation comparing pericardial strip versus ring annuloplasties. Patients and methods: From January 2008 to December 2013, we operated 59 patients (male:female, 41:18, with a mean age of 34 ± 14 years) for functional tricuspid regurgitation. Tricuspid annuloplasty was done using pericardial strip in 39 patients and ring in 20 patients. Concomitant procedures were mitral valve replacement in 66% of patients, aortic valve replacement in 5% and double valve replacement in 29%. Clinical and echocardiographic data were collected. Results: Preoperative characteristics of the two groups were similar regarding age, percentage of female patients, New York Heart Association functional class and pulmonary artery pressure. More patients with preoperative right ventricular dysfunction were found in pericardial annuloplasty group although this was not statistically significant (13 versus 5;P = 0.52). Operative times were similar in both groups. We had one mortality case (1.69%) due to low cardiac output in the pericardial group. Postoperative complications included reexploration for bleeding in one patient and chronic heart failure in another patient. The average follow up period was 3 years and it was complete in 100% of patients. Postoperative freedom from recurrent moderate tricuspid regurgitation was 90% in both groups. Conclusion: Pericardial strip annuloplasty is a simple, inexpensive, reproducible and efficient technique that has comparable results to ring annuloplasty.
