Brief Summary

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.

Detailed Description

The tricuspid valve controls the flow of blood in your heart between the right ventricle and the right atrium. TR is a condition where the valve does not close fully when it is supposed to and blood can then leak back into the right atrium. When TR becomes severe, surgery is usually performed to correct it. The purpose of the research is to determine whether repairing a tricuspid valve in patients with mild to moderate TR, at the time of planned mitral valve surgery, would improve the heart health of those who receive it compared to those who do not. There are no new or "experimental" procedures being tested in this study: both the mitral valve procedure and the tricuspid valve repair procedure are well established surgeries and are regularly performed together in patients who have severe TR. The available evidence addressing this issue is not definite: it is based on less rigorous methods of investigation, and the results have been conflicting. The study being proposed here will use rigorous scientific methods and should result in a very high level of certainty about what surgical treatment is best for patients with your condition.

This study will enroll people scheduled for mitral valve surgery with mild to moderate tricuspid regurgitation.

Recruitment & Eligibility

Target Recruitment
401
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 none/trace or mild TR, determined by echocardiography.

  • Age ≥ 18 years

  • Able to sign Informed Consent and Release of Medical Information forms

    • "Degenerative mitral valve disease refers to a spectrum of conditions in which morphologic changes in the connective tissues of the mitral valve cause structural lesions . . ., such as chordal elongation, chordal rupture, leaflet tissue expansion, and annular dilation typically resulting in mitral regurgitation due to leaflet prolapse." This definition excludes rheumatic heart disease. (Anyanwu AC, Adams DH. (2007) Etiological classification of degenerative mitral valve disease: Barlow's disease and fibroelasticity deficiency. Semin Thorac Cardiovasc Surg; 19(2): 90-6).

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Treatment Failure24 Months

The primary outcome of this trial is treatment failure defined as the composite of (1) death from any cause, (2) reoperation for TR, (3) presence of severe TR at two years post randomization or, for patients enrolled with less than moderate TR and annular dilatation, progression by two grades (i.e., from none/trace TR to moderate TR) at two years post randomization.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Major Adverse Cardiac and Cerebrovascular Events (MACCE)up to 24 Months

Major Adverse Cardiac and Cerebrovascular Events (MACCE) is defined as a non-weighted composite score comprised of the following components: Death, Stroke, and Serious heart failure events

Number of Participants With NYHA Classification I-IVat 24 Months

Functional status will be assessed by the New York Heart Association (NYHA) Classification scale which ranges from 1 (no physical limitations) to 4 (severe limitation of physical activity).

1. Class I - No symptoms and no limitation in ordinary physical activity, e.g. shortness of breath when walking, climbing stairs etc.

2. Class II - Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity.

3. Class III - Marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g. walking short distances (20-100 m).Comfortable only at rest.

4. Class IV - Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients.

5. No NYHA class listed or unable to determine

Peak Tricuspid Annular Velocity24 Months
Diuretic Use24 Months

The diuretic requirements of patients will be assessed.

Number of Participants With Degree of TRup to 24 Months

Degree of TR assessed by echocardiography, categorized according to American Society of Echocardiography guidelines as none/mild/moderate/severe.

Right Ventricular Fractional Area Change (RVFAC)24 Months

EuroQoL (EQ-5D)24 Months

Quality of Life assessed by EuroQoL (EQ-5D) - a standardised instrument for use as a measure of health outcome. Scores on the EuroQol (EQ-5D) visual analogue scale range from 0 (worst imaginable health) to 100 (best imaginable health). Higher scores indicate higher levels of health.

SF-1224 Months

Quality of Life assessed by SF-12. A measure of perceived health (health-related quality of life \[QoL\]) that describes the degree of general physical health status and mental health distress. Higher scores indicate higher levels of health. The physical and mental health scores on the 12-Item Short Form Survey (SF-12) are reported as T scores (mean, 50±10, 50 indicates the population mean with a standard deviation of 10), with higher scores indicating better health status.

KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life, in which higher scores reflect better health status. Scores on the Kansas City Cardiomyopathy Questionnaire (KCCQ) overall summary range from 0 to 100, with higher scores indicating a better quality of life and fewer symptoms and physical limitations associated with heart failure.
