1005 STROKE VOLUME INDEX AND TRANSVALVULAR FLOW RATE TRAJECTORIES IN SEVERE AORTIC STENOSIS TREATED WITH TAVR

Abstract Aims The prognostic impact of flow trajectories according to stroke volume index (SVi) and transvalvular rate (FR) in patients with severe aortic stenosis (AS) undergoing transcatheter valve replacement (TAVR) remains poorly assessed. We evaluated compared SVi FR prior after TAVR for AS. Methods results Patients were categorized (<35 ml/m2) (<200 ml/sec). association pre- post-TAVR all-cause mortality up 3 years was assessed multivariable Cox regression models. Among 980 pre-TAVR assessment, reduced 41.3% 48.1%. Baseline status not an independent predictor (SVi: HR 1.39, 95%CI 0.81-2.40, FR: 0.86, 0.51-1.46). 731 early (5 days, IQR 2-29) recovered 40.1% 49.0% baseline low-flow. Reduced following (HR 2.08, 1.07-4.04) while 0.68, 0.34-1.36). Three-year estimated lower as (13.3% vs 37.7% vs, p=0.003) similar normal (p=0.317). Conclusions mid-term among all-comers AS TAVR. Flow recovery frequent. Post-TAVR FR, but SVi, independently associated mortality. By impacting status, AV modifies the outcomes.
