Posada-Martinez EL, Fritche-Salazar JF, Arias-Godinez JA, et al. - Via performing this prospective, observational study, researchers sought to determine if low-cardiac-output syndrome (LCOS) after surgical aortic valve replacement (SAVR) in patients with left ventricular ejection fraction ≥ 40% could be predicted via assessing right ventricular free wall longitudinal strain (RVFWSL). Among 75 assessed patients with severe aortic stenosis and LVEF ≥ 40% who underwent SAVR, the incidence of LCOS was 20%. Multivariate analysis suggested cross-clamp time and RVFWSL as the only predictors of LCOS in patients with severe aortic stenosis and LVEF ≥ 40% undergoing SAVR. RVFWSL less than –17.3% may lead to recognition of patients at raised risk for LCOS.
