Tricuspid regurgitation is common in patients with heart valve disease, both flexible band and rigid ring annuloplasty can correct this anomaly. However, there is no data to address which one can bring more benefits to these patients with combined heart valve disease. This study aims to prospectively compare the efficacy and long term outcomes of flexible band versus rigid ring annuloplasty for the correction of tricuspid regurgitation.
