Using the GE Voluson E10 ultrasound system and Fetal HQ software, cardiac parameters such as global sphericity index (GSI), global longitudinal strain (GLS), ejection fraction (EF), and fractional area change (FAC) were measured. Segmental end\u2010diastolic diameters (EDD) and sphericity indices (SI) for both ventricles were analyzed. Statistical analyses compared groups and assessed correlations between VSD size and left ventricular function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The VSD group displayed significant reductions in left ventricular segmental EDD and increases in right ventricular SI, reflecting localized geometric changes. Left ventricular GLS, EF, FAC, and stroke volume were notably reduced in the VSD group, indicating compromised function.
