This study aimed to validate cine MRI-derived ventricular volume measurements with a semi-automatic threshold-based segmentation algorithm in a model of congenital heart disease, by comparing it with the standard method of manual tracing MRI and angiocardiography. This novel method allowed more accurate and objective ventricular volumetry in both ventricles of congenital heart diseases and will be of great help for practical use.
