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.
Full Title of Study: “Flexible Band Versus Rigid Ring Annuloplasty for the Correction of Tricuspid”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Treatment
- Masking: Double (Care Provider, Outcomes Assessor)
- Study Primary Completion Date: December 2021
- Procedure: Tricuspid Annuloplasty
- Patients will undergo repair of tricuspid regurgitation
Arms, Groups and Cohorts
- Active Comparator: Group Ring
- Patients in Group Ring will undergo tricuspid rigid ring annuloplasty
- Active Comparator: Group Band
- Patients in Group Band will undergo flexible band annuloplasty
Clinical Trial Outcome Measures
- Improvement in severity of tricuspid regurgitation
- Time Frame: within 3 months
- Improvement in tricuspid regurgitation: refers to Mild or No tricuspid regurgitation Tricuspid regurgitation is graded as mild, moderate, and severe based on regurgitant jet area
- Time Frame: up to 3 months of intervention
- Mortality: Mortality within hospital stay or 1 month postoperative.
