Evaluating the Benefit of Concurrent Tricuspid Valve Repair During Mitral Surgery


About this study

The purpose of the research is to determine whether repairing a tricuspid valve (TV) in patients with mild to moderate tricuspid regurgitation (TR), at the time of planned mitral valve surgery (MVS), would improve the heart health of those who receive it compared to those who do not. At this point, the medical community is split in their opinion on whether surgeons should routinely repair mild to moderate TR in patients who are undergoing planned mitral valve surgery, and this study will answer this question.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Undergoing MVS for degenerative MR with (a) Moderate TR as determined by transthoracic 2D echocardiography, or (b) Tricuspid annular dimension ≥ 40 mm (index: ≥21mm/M2 BSA) and trace/mild TR, determined by echocardiography.
  • Age ≥ 18 years
  • Able to sign Informed Consent and Release of Medical Information forms

Exclusion Criteria:

  • Functional MR
  • Evidence of sub-optimal fluid management (e.g., lack of diuretics, weight in excess of dry weight) in the opinion of the cardiology investigator
  • Structural / organic TV disease
  • Severe TV regurgitation as determined by preoperative transthoracic echocardiography (TTE)
  • Implanted pacemaker or defibrillator, where the leads cross the TV from the right atrium into the right ventricle
  • Concomitant cardiac surgery other than atrial fibrillation correction surgery (PVI, Maze, LAA closure), closure of PFO or ASD, or CABG
  • Cardiogenic shock at the time of randomization
  • STEMI requiring intervention within 7 days prior to randomization
  • Evidence of cirrhosis or hepatic synthetic failure
  • Severe, irreversible pulmonary hypertension in the judgment of the investigator
  • Pregnancy at the time of randomization
  • Therapy with an investigational intervention at the time of screening, or plan to enroll patient in additional investigational intervention study during participation in this trial
  • Any concurrent disease with life expectancy < 2 years
  • Unable or unwilling to provide informed consent
