Cardiovascular interventionsAbstract: BACKGROUND: Prior studies assessing the association between baseline LVH and outcomes after surgical or TAVR for aortic stenosis (AS) have yielded conflicting results.CONCLUSIONS: Severe baseline LVH is associated with higher 5-year death and rehospitalization rates after TAVR.

The presence and severity of LVH was determined by LVMi using American Society of Echocardiography sex-specific cutoffs.OBJECTIVES: This study sought to evaluate the association between severity of left ventricular hypertrophy (LVH) before transcatheter aortic valve replacement (TAVR) and outcomes out to 5 years.RESULTS: Among 4,280 patients, those with no (n = 1,325), mild (n = 777), moderate (n = 628), and severe (n = 1,550) LVH had 5-year rates of death of 32.8%, 37.3%, 37.2%, and 44.8%, respectively (p < 0.001), and 5-year rates of cardiovascular (CV) death or rehospitalization of 33.6%, 39.2%, 42.4%, and 49.2%, respectively (p < 0.001). After adjustment, severe LVH (compared with no LVH) was associated with increased all-cause death (adjusted hazard ratio: 1.16; 95% confidence interval: 1.00 to 1.34; p = 0.04) and CV death or rehospitalization (adjusted hazard ratio: 1.34; 95% confidence interval: 1.16 to 1.54; p < 0.001), but no increased hazard was observed for mild or moderate LVH. In spline analyses performed in males and females separately, there was a consistent linear association between increased LVMi and an increased adjusted hazard of CV mortality or rehospitalization. A similar relationship was observed for all-cause death in females, but not males.All authors: Alu MC, Asch FM, Clavel MA, Cremer P, Daubert M, Douglas PS, Elmariah S, Gertz ZM, Gonzales H, Hahn RT, Jaber WA, Khalique OK, Leon MB, Lindman BR, Pibarot P, Thourani VH, Weissman NJ, Zhang YOriginally published: Jacc: Cardiovascular Interventions. 13(11):1329-1339, 2020 Jun 08.Fiscal year: FY2020Digital Object Identifier: Date added to catalog: 2020-08-26
