Valvular & structural heart diseaseCohort study
Ventricular Interaction and Clinical Outcomes in Patients Undergoing Transcatheter Tricuspid Valve Repair
- Retrospective cohort study
- Median follow-up 384 days (Q1-Q3: 189-734 days)
Authors' conclusion
Ventricular interaction, assessed by LV eccentricity index, was associated with clinical outcomes after TTVr, and its postprocedural improvement was linked to better outcomes.
Study context
- Population
- Patients undergoing transcatheter tricuspid valve repair (TTVr)
- Participants
- 304 patients
- Exposure
- Left ventricular (LV) eccentricity index ≥1.2 vs <1.2
- LV eccentricity index ≥1.2n = 168
- Outcome
- Composite of:
- Mortality
- HF hospitalization
- Follow-up
- Within 1 year
Main finding
As reported in the abstract
Adjusted hazard ratio
1.66
95% CI 1.04–2.65
P = 0.034
LV eccentricity index ≥1.2 vs LV eccentricity index <1.2
adjusted HR 1.66 (95% CI 1.04–2.65); P = 0.034
Observational data: associations, not effects.
Further findings
Baseline LV eccentricity index
- Mean LV eccentricity index
- 1.23 ± 0.20
- LV eccentricity index ≥1.2
- 168 of 304 (55.3%)
Improvement of LV eccentricity index to <1.2 at discharge (baseline ≥1.2)
- Improved to <1.2 at discharge
- 83 (49.4%)
- Improvement associated with lower risk of composite outcome vs persistently increased LV eccentricity index
- Smaller RV area, larger left atrial volume index, greater tricuspid regurgitation (TR) reduction and procedural success related to improvement
