Illustration showing the various types of left ventricular thickening. In a normal heart, the LV wall thickness, septal/lateral wall ratio, LV mass, LV volume, relative wall mass and ejection fraction are normal; in concentric hypertrophy, the wall thickness, LV mass and relative wall mass are increased. While septal/lateral wall ratio is normal, the LV volume is normal or increased and ejection fraction is normal or decreased; in asymmetric hypertrophy, the wall thickness, LV mass and relative wall mass are increased, but the septal/lateral wall ratio is increased. In eccentric hypertrophy, the wall thickness and septal/lateral wall ratio are normal, but LV mass and LV volume are increased, while ejection fraction and relative wall mass are decreased. In concentric remodelling, the relative wall mass is increased, the LV volume is decreased, but septal/lateral wall ratio, wall thickness, LV mass and ejection fraction are normal. In asymmetric remodelling, the relative wall mass is increased and LV volume is decreased. While septal/lateral wall ratio is increased, wall thickness, LV mass and EF are normal
