Prognostic value of RV isovolumic acceleration and tissue strain in moderate HFrEF

Right ventricular (RV) dysfunction in heart failure (HF) with reduced left ventricular ejection fraction (LVEF) is associated with a poorer prognosis. No studies to date have investigated the prognostic utility of RV isovolumic acceleration (IVA) measured at tissue Doppler imaging (TDI) in HF. RV strain instead has been already correlated to a poorer prognosis in these patients. We aimed to assess the predictive value of both parameters in this context.
