Usefullness of peak mitral regurgitation velocity to left ventricular outflow tract time velocity integral ratio as a new prognostic marker for one year and long term mortality in failing heart

Background and aim Systemic vascular resistance (SVR) is useful for risk estimation and therapy guidance in HF. It has been showed that the ratio of peak mitral regurgitation velocity (MRV) to left ventricular outflow tract velocity-time integral (LVOT VTI) correlated positively with SVR. We aimed to assess the association of MRV/LVOT VTI ratio with established prognostic markers and its prognostic role for predicting one year and long term...
