Evaluation of multiple ventricular septal defects using three-dimensional reconstruction models†.

Area of Science:

• Cardiovascular Surgery
• Medical Imaging
• Congenital Heart Disease

Background:

• Advancements in 3D imaging for congenital heart disease exist, but precise modeling of complex ventricular septal defects remains a challenge.
• Accurate pre-operative visualization is crucial for planning surgical interventions in complex cardiac anomalies.

Purpose of the Study:

• To evaluate the utility of 3D printed models and computer graphics in surgical planning for complex multiple ventricular septal defects.
• To assess the effectiveness of these 3D tools in visualizing and understanding the spatial characteristics of ventricular septal defects.

Main Methods:

• Seven patients with complex multiple ventricular septal defects underwent pre-operative evaluation.
• Multi-slice computed tomography data was used to create 3D printed models and computer graphics.
• These 3D visualizations were used for surgical decision-making and planning.

Main Results:

• 3D printed models identified 60% of muscular ventricular septal defects (VSDs), while 3D computer graphics identified 67%.
• Both methods enabled evaluation of VSDs from both left and right ventricular perspectives.
• The tools facilitated a comprehensive assessment of defect morphology.

Conclusions:

• Preliminary findings suggest 3D printed models and computer graphics are valuable tools for planning surgeries in patients with complex multiple VSDs.
• 3D models enhance understanding of the spatial positioning of defects.
• High-quality 3D computer graphics offer precise details on VSD size, shape, and location, particularly from the left ventricular view.
