The ratio between left atrial reservoir and septal E/e’: a new parameter reflecting atrio-ventricular function which is associated with a worse outcome among heart failure outpatients
Background. Two-dimensional speckle tracking (2D-ST) analysis allows to evaluate both atrial and ventricular function. Recently, it has been demonstrated that the ratio between left atrial reservoir (LAr) assessed by 2D-ST and the E/e’ ratio could allow a more accurate estimation of left ventricular filling pressure. Aim of the study….
