Case report reveals morphological insights of truncus arteriosus in rare anatomical variations, suggesting implications for surgical strategy.
We report a rare case of truncus arteriosus arising exclusively from the right ventricle associated with a restrictive inlet-type ventricular septal defect. Three-dimensional reconstruction provided essential spatial understanding for operative planning and highlights the morphological variability of conotruncal development.
