Contribution To Literature:

The TRILUMINATE Pivotal trial showed that tricuspid valve TEER was effective and improved quality of life.

Description:

The goal of the trial was to evaluate percutaneous tricuspid valve transcatheter edge-to-edge repair (TEER) compared with medical therapy among patients with symptomatic severe tricuspid regurgitation.

Study Design

  • Randomization
  • Parallel

Patients with symptomatic severe tricuspid regurgitation were randomized to tricuspid valve TEER (n = 175) vs. usual care (n = 175).

  • Total number of enrollees: 350
  • Duration of follow-up: 12 months
  • Mean patient age: 78 years
  • Percentage female: 56%
  • Percentage with diabetes: 16%

Inclusion criteria:

  • Symptomatic severe tricuspid regurgitation
  • New York Heart Association class II, III, IVa symptoms
  • Receiving stable guideline-directed medical therapy for heart failure for ≥30 days
  • Intermediate or greater risk for mortality/morbidity with tricuspid valve surgery

Exclusion criteria:

  • Indication for other valve intervention
  • Severe pulmonary hypertension >70 mm Hg
  • Left ventricular ejection fraction ≤20%
  • Anatomy not suitable for TEER therapy

Other salient features/characteristics:

  • Coaptation gap: 5.5 mm
  • Tricuspid regurgitation severity: severe = 25%, massive = 21%, torrential = 51%

Principal Findings:

The primary outcome, hierarchical composite of death from any cause or tricuspid valve surgery; hospitalization for heart failure; and improvement in quality of life, as measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ) at 12 months, had 11,348 wins in the TEER group versus 7,643 wins in the usual care group (win ratio = 1.48, p = 0.02).

Secondary outcomes:

  • Tricuspid regurgitation of moderate or less severity at 30 days: 87.0% in the TEER group vs. 4.8% in the usual care group (p < 0.001)
  • Change in KCCQ score from baseline to 12 months: 12.3 in the TEER group vs. 0.6 in the usual care group (p < 0.001)
  • Mean increase in KCCQ score: 2 points when no change in tricuspid regurgitation (from baseline to 12 months), 6 points when 1 grade reduction in tricuspid regurgitation, and 18 points when ≥2 grade reduction in tricuspid regurgitation
  • Major adverse events at 30 days: 1.7% in the TEER group

Interpretation:

Among patients with symptomatic severe tricuspid regurgitation, TEER was effective. This therapy improved tricuspid regurgitation to moderate or less severity in 87% of patients. Reduction in tricuspid regurgitation was associated with improvements in quality of life. The largest increase in KCCQ was observed among those with the largest reduction in tricuspid regurgitation. Patients enrolled in this trial will be followed for 5 years.
