Severe or moderate mitral regurgitation is associated to worse evolution after TAVR. However, we should not forget the tricuspid valve that, even though not extensively researched, is also associated to a negative impact in its evolution.
A meta-analysis of 12 studies with a total 41485 patients was carried out.
Early mortality (up to 6 months) was 1.8 times higher with severe or ≥moderate tricuspid regurgitation (OR, 1.80; 95% CI, 1.01 to 3.19; P=0.05). Between 6 and 30 months after TAVR, it was 1.9 times higher (HR/OR, 1.96; 95% CI, 1.35 to 2.85; P = 0.0004).

A second meta-analysis of 7 homogeneous studies was carried out and mortality between 6 and 30 months was 2.25 times higher (HR,2.25; 95% CI, 1.20–4.24; P= 0.01).
Conclusion
Significant tricuspid regurgitation (severe or ≥moderate) is associated to an approximate two-fold increase in early or mid-term all-cause mortality in patients with aortic stenosis undergoing TAVR.
