Inconsistent use of systolic pulmonary artery pressure cut-off values in previous studies limits our ability to draw meaningful conclusions regarding the prognostic role of PH in assessment of TAVR candidates. A total of 415 consecutive patients who underwent TAVR were included in the present study. Two groups were compared based on receiver-operating characteristics curve analysis for the best SPAP value to predict outcome, yielding 2 study groups of no/mild PH (<50 mm Hg; n = 172, 41%) versus moderate/severe PH (>50 mm Hg; n = 243, 59%). Demographics and co-morbidities were comparable between the 2 groups; however, right-sided cardiac failure (35% vs 19.8%, p = 0.02) and mitral regurgitation (18.4% vs 8.6%, p = 0.007) were more frequent in patients with moderate/severe PH. Procedural characteristics and complications were comparable between the groups. Although there was an early overall decrease in SPAP postprocedure, only 26% of moderate/severe patients with PH experienced a significant decrease in SPAP (>10 mm Hg). The 30-day (14.5% vs 7.4%, p = 0.02) and 1-year mortality (30.8% vs 21%, p = 0.02) was higher in moderate/severe patients with PH. In multivariate analysis, systolic pulmonary artery pressure and chronic lung disease were identified as independent predictors for mortality at 1 year. PH is a frequent co-morbidity in patients with severe aortic stenosis who underwent TAVR. Significantly elevated pulmonary artery pressures at baseline may serve as a poor prognostic factor when performing preprocedural assessment of the patients.Copyright � 2015 Elsevier Inc.
