Assessment of age-related changes in left ventricular twist by 3-dimensional speckle-tracking echocardiography.

Abstract

OBJECTIVES The purpose of this study was to determine the normal value of left ventricular (LV) twist in 3-dimensional (3D) geometry and to study the effects of aging on 3D LV twist by sophisticated newly developed 3D speckle-tracking echocardiographic techniques. METHODS Recent developments in miniaturized ultrasound arrays have provided us with high… (More)
