Ring Versus Suture Annuloplasty For Functional Tricuspid Regurgitation In Rheumatic Mitral Valve Diseases


This study aims to compare whether De Vega's Suture annuloplasty is equally effective in reducing the progression of Functional Tricuspid regurgitation as that claimed for Ring annuloplasty in Rheumatic Heart Disease patients with concurrent Mitral valve replacement.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: September 2016

Detailed Description

Functional Tricuspid regurgitation (FTR) occurs due to annular dilatation in association with left sided valve disease and is more commonly seen than primary pathology in patients with Rheumatic mitral valve disease. FTR occurs due to increased right ventricle after load that leads to either dilatation or geometric deformation of Tricuspid annulus. If left untreated, FTR may worsen and increase morbidity and mortality.


  • Procedure: Tricuspid Annuloplasty
    • Patients will undergo repair of tricuspid regurgitation

Arms, Groups and Cohorts

  • Active Comparator: Group R (ring)
    • Patients in Group R will undergo tricuspid ring annuloplasty
  • Active Comparator: Group S (suture)
    • Patients in Group S will undergo De Vega’s suture annuloplasty

Clinical Trial Outcome Measures

Primary Measures

  • Improvement in severity of FTR
    • Time Frame: within 3 months
    • Definitions: Improvement in FTR: refers to Mild or No TR Tricuspid regurgitation is graded as mild, moderate, and severe based on regurgitant jet area i. <5cm2 = Mild ii. 6-10cm2 = Moderate iii. >10cm2 = Severe

Secondary Measures

  • Mortality
    • Time Frame: up to 3 months of intervention
    • Mortality: Mortality within hospital stay or 3 months postoperative.
