Abstract
Aims: Pulmonary hypertension (PH) is common in severe symptomatic left-sided valvular disease, particularly in aging populations. Inconsistent results have been reported concerning the association between PH and adverse outcomes after aortic valve replacement for aortic stenosis (AS). We therefore retrospectively investigated the prognostic significance of PH using peak tricuspid regurgitation velocity (TRV), as defined by the current European Society of Cardiology (ESC)/European Respiratory Society (ERS) guidelines, in a large cohort of patients with severe AS. Methods and results: One thousand and nineteen patients (541 men; mean age 74 ± 11 years) with severe AS (aortic valve area (AVA) <1 cm2 and/or indexed AVA <0.6 cm2/m2 of body surface area) and LV ejection fraction ≥50% were included. Patients were divided into three groups according to the level of their peak TRV at the time of enrolment: Group 1 (n = 695, 68%) when TRV was ≤2.8 m/s; Group 2 (n = 212, 21%) when TRV was between 2.9 m/s and 3.4 m/s and Group 3 (n = 112, 11%) when TRV was > 3.4 m/s. Median overall follow-up was 31 [6-182] months. On univariate analysis, overall mortality during follow-up was globally different between groups (P < 0.001). On multivariate analysis, Group 3 (TRV >3.4 m/s) exhibited significant excess mortality after adjustment for covariates of prognostic importance (P = 0.032) and after further adjustment for surgery (P = 0.012), using Group 1 as the reference group. Dividing the whole population into two groups with a 3.4 m/s TRV threshold, overall mortality during follow-up was higher in the PH group [hazard ratio (HR) 1.87; 95% confidence interval [1.37-2.56]; P < 0.001)]. On multivariate analysis, after covariate adjustment, including surgery, Group 3 exhibited major excess mortality (adjusted HR 1.46 [1.10-1.95], P = 0.009). Conclusion: This study demonstrates the negative impact of pulmonary pressure, as assessed by current ESC/ERS guidelines, on long-term outcome of patients with severe AS, irrespective of functional status, chronic obstructive pulmonary disease, AS severity and surgery. Baseline TRV should therefore be taken into account in the management of severe AS.
