Left Ventricular Hypertrophy Does Not Affect 1-Year Clinical Outcomes in Patients Undergoing Transcatheter Aortic Valve Replacement.

Journal Article (Journal Article;Multicenter Study)

OBJECTIVES: The aim of this study was to evaluate the association between pre-procedural left ventricular hypertrophy (LVH) patterns and clinical outcomes after transcatheter aortic valve replacement (TAVR). BACKGROUND: The association between pre-procedural LVH pattern and severity and clinical outcomes after TAVR is uncertain. METHODS: Patients (n = 31,199) across 422 sites who underwent TAVR from November 2011 through June 2016 as part of the Society of Thoracic Surgeons/American College of Cardiology TVT (Transcatheter Valve Therapies) Registry linked with the Centers for Medicare and Medicaid Services database were evaluated by varying LVH patterns, according to sex-specific cutoffs for left ventricular mass index and relative wall thickness. The association between LVH pattern (concentric remodeling, concentric LVH, and eccentric LVH) and outcomes (rates of mortality, myocardial infarction [MI], stroke, new dialysis requirement) at 1-year follow-up were evaluated using multivariate hazard models. RESULTS: There were no significant associations between concentric remodeling (death: adjusted hazard ratio [HR]: 1.03; 95% confidence interval [CI]: 0.93 to 1.15; MI: HR: 1.05; 95% CI: 0.76 to 1.46; stroke: HR: 1.11; 95% CI: 0.89 to 1.39; new dialysis: HR: 0.86; 95% CI: 0.64 to 1.15), concentric LVH (death: HR: 1.04; 95% CI: 0.95 to 1.15; MI: HR: 1.12; 95% CI: 0.82 to 1.52; stroke: HR: 1.14; 95% CI: 0.92 to 1.40; new dialysis: HR: 1.17; 95% CI: 0.90 to 1.52), or eccentric LVH (death: HR: 0.98; 95% CI: 0.87 to 1.10; MI: HR: 1.07; 95% CI: 0.71 to 1.63; stroke: HR: 1.01; 95% CI: 0.78 to 1.32; new dialysis: HR: 1.25; 95% CI: 0.92 to 1.70) and outcomes at 1 year compared with patients without LVH. CONCLUSIONS: In a contemporary cohort of patients who underwent TAVR, pre-procedural LVH according to left ventricular mass index and relative wall thickness was not associated with adverse outcomes at 1-year follow-up. TAVR is likely to benefit patients with severe aortic stenosis regardless of the presence of LVH.
