A Novel Mathematical/Numerical Formula for Assessing Right Ventricular Torsion Using Echocardiographic Imaging
arXiv:1504.05488
Abstract
Recently, the ventricular torsional parameters have received special attention because of their significant role in the ventricular systolic and diastolic function. Right ventricular (RV) rotational deformation is a sensitive index for RV performance but difficult to measure. Having assumed RV as a conic shape, the present study serves a novel mathematical formula of right ventricular rotation that uses velocity vector imaging (VVI) for quantifying RV.
