Table 6. Median regression coefficients for the association between pre and post transcatheter aortic valve replacement tricuspid regurgitation severity and hospital length of stay.
| Variable | TR severity | Regression coefficients | |
|---|---|---|---|
| Univariate | Multivariate | ||
| Pre-TAVR tricuspid regurgitation severity | Moderate vs. mild | 1.0 (−1.5 to 3.5) | 0.83 (−3.7 to 5.4) |
| Severe vs. mild | −1.0 (−3.4 to 1.4) | 1.61 (−5.6 to 8.9) | |
| Post-TAVR tricuspid regurgitation severity | Moderate vs. mild | 1.0 (−1.5 to 3.5) | 3.5 (−1.5 to 8.5) |
| Severe vs. mild | 10.0 (6.8 to 13.2) | 9.9 (2.9 to 17.0) | |
| TR no change/worsened vs. remained mild | 2.0 (−0.45 to 4.5) | 3.6 (−1.6 to 8.8) | |
The coefficient regression coefficients represent the difference in hospital stay (days; median, 95% CI). Multivariate models were adjusted for age, sex, smoking, left ventricular ejection fraction, mitral regurgitation severity, STS risk score, history of CABG and history of myocardial infarction. Italic indicates statistically significant values. TAVR, transcatheter aortic valve replacement; TR, tricuspid regurgitation.
