Abstract

Objectives: The aim of this study was to assess the association of baseline left ventricular diastolic dysfunction (LVDD) with health status outcomes of patients undergoing transcatheter aortic valve replacement (TAVR). Background: Although LVDD in patients with aortic stenosis is associated with higher mortality after TAVR, it is unknown if it is also associated with health status recovery. Methods: In a cohort of 304 patients with interpretable echocardiograms, undergoing TAVR, LVDD was categorized at baseline as absent (grade 0), mild (grade 1), moderate (grade 2), or severe (grade 3). Disease-specific health status was assessed using the 12-item Kansas City Cardiomyopathy Questionnaire overall summary score (KCCQ-OS) at baseline and at 1-month and 12-month follow-up. Association of baseline LVDD with health status at baseline and follow-up after TAVR was assessed using a linear trend test, and association with health status recovery (change in KCCQ-OS) was examined using a linear mixed model adjusting for baseline KCCQ-OS. Results: Twenty-four (7.9%), 54 (17.8%), 186 (61.2%), and 40 (13.2%) patients had LVDD grades of 0, 1, 2, and 3, respectively. Baseline KCCQ-OS was 61.3 ± 22.7, 51.0 ± 26.1, 44.7 ± 25.7, and 44.4 ± 21.9 (p = 0.004) in patients with LVDD grades of 0, 1,2 and 3. At 1 and 12 months after TAVR, LVDD was not associated with KCCQ-OS. Recovery in KCCQ-OS after TAVR was substantial and similar in patients across all severities of LVDD. Conclusions: Although LVDD is associated with health status prior to TAVR, patients across all severities of LVDD have similar recovery in health status after TAVR.
