Implication

Technical report demonstrates a workflow for designing custom 3D-printed surgical patches in complex congenital heart disease, highlighting the role of personalized anatomical modeling.

Key Points

Provide a practical workflow for converting standard computed tomography imaging into 3D-printable anatomical models and custom patches for complex congenital heart disease repair.
Segmented cardiac chambers and great vessels from standard DICOM computed tomography datasets to generate standard tessellation language (STL) files.
Optimized the digital anatomical mesh and engineered a customized ventricular septal defect patch using computer-aided design (CAD) software.
Successfully established a multi-step post-processing pipeline to convert standard CT DICOM data into 3D-printable STL files using segmentation and CAD-based refinement.
Engineered an anatomically accurate virtual patch custom-fitted to the patient's ventricular septal defect alongside the corresponding cardiac model for physical 3D printing.
