Left ventricular outflow tract velocity-time integral (LVOT-VTI) improves risk stratification in heart failure patients with secondary mitral regurgitation
Anno:
2023
Background: Reduced left ventricular ejection fraction (LVEF) has been used as a key criterion for the management of mitral regurgitation (MR) in patients with heart failure (HF), including the decision about mitral valve repair. However, LVEF, not taking into account mitral regurgitant volume, may be an imprecise predictor of…
