Abstract |
Background |
Predictive factors of significant functional tricuspid regurgitation (FTR) are not completely understood. We investigated sex-related differences in predictors of FTR progression.
Method |
Clinical and echocardiographic variables were recorded in a prospective single-centre observational cohort of 251 consecutive stable patients with FTR. Multivariable logistic regression analyses stratified by sex were performed to identify predictors of significant FTR.
Results |
The mean age of the whole cohort was 72.2±11.4 years, and 133 (53%) patients were women. Females tended to have a higher prevalence of significant FTR (22.6% vs 13.6%; p=0.066). Women were also older than men (mean age 74.4 vs 69.6 years; p<0.001), with more frequent history of arterial hypertension, worse New York Heart Association functional class, higher E/e' quotient, and higher left ventricular ejection fraction. The independent predictors of significant FTR in women were atrial fibrillation (AF) (odds ratio [OR] 10.8, 95% confidence interval [CI] 2.9–40.7; p<0.001), indexed tricuspid diameter annulus (OR 1.24, 95% CI 1.04–1.47; p=0.017), and pulmonary artery systolic pressure (PASP) (OR 1.09, 95% CI 1.04–1.15; p=0.001). The independent predictors of outcome in men were indexed tricuspid tenting height (OR 2.71, 95% CI 1.20–6.11; p=0.016), indexed tricuspid diameter annulus (OR 1.98, 95% CI 1.26–3.09; p=0.003), and PASP (OR 1.08, 95% CI 1.01–1.16; p=0.021).
Conclusions |
The presence of AF and longer indexed tenting height convey a greater risk of significant FTR in females and males, respectively. These findings suggest the existence of different physiopathological mechanisms involved in the progression of FTR in both sexes.
