Relative Wall Thickness (RWT) Calculator

About This Calculator Relative Wall Thickness (RWT) is a geometric index used in echocardiography to assess the pattern of left ventricular remodeling. It is calculated as: RWT = (2 × PWd) / LVEDD Interpretation commonly used in clinical practice: - RWT ≤ 0.42 → Normal geometry or eccentric hypertrophy - RWT > 0.42 → Concentric remodeling or concentric hypertrophy References 1.

RV Involvement Index Calculator

Right Ventricular (RV) Involvement Index: Explanation and Clinical Context The RV Involvement Index is a composite echocardiographic score designed to quantify right ventricular dysfunction by integrating three key parameters: RV fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE), and the right ventricular myocardial performance index (RV MPI). This index provides a continuous measure of
