Provides Z-scores, percentiles, and reference ranges for ventricular cardiac parameters in children (0-18 years) based on gender and body surface area (BSA), which is calculated from the provided height and weight.

The reference values are derived from the paper: 'Multicentre reference values for cardiac magnetic resonance imaging derived ventricular size and function for children aged 0–18 years' (van der Ven et al., 2020). All calculations are based on allometric models using the patient's BSA.
