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.
