Utility of a bespoke 3-dimensional printed model in complex transposition

Figures

• 

  Three-dimensional printed model showing a complex transposition of the great arteries.

  Figure 1. Diagram describing the intracardiac repair. The green triangle demonstrated the ventricular septal defect (VSD) enlargement with infundibular resection and the dotted yellow line indicates the intracardiac baffle. Ao, Aorta.

  Figure 2. Multimodal images showing transposition of the great arteries (TGA), ventricular septal defect (VSD), small pulmonary artery (PA) and single coronary artery. A and B, reconstruction in 3 dimensions of the magnetic resonance imaging scan. C, Echocardiogram short axis showing a single coronary artery with intramural and intra-arterial trajectory. D, The 3-dimensional models. Ao, Aorta; LVOT, left ventricular outflow tract; RCA, right coronary artery; LMA, left mainstem coronary artery.

  Figure 3. A, Postoperative echocardiographic 2-dimensional apical view, showing the intracardiac baffle, unobstructed left ventricular outflow tract, and anastomosis between pulmonary artery and the posterior wall of the aorta (Damus-Rastelli). B, Magnetic resonance imaging single-shot steady-state free precession images in sagittal view showing the right ventricle-pulmonary artery conduit (left panel), the Damus-Rastelli (central panel), and the ascending aorta (right panel). Ao, Aorta; PA, pulmonary artery; LVOT, left ventricular outflow tract.

  Figure 4. Three-dimensional reconstructed image showing complex transposition of the great arteries. A, External view, B, With anterior wall of the right ventricle removed. Ao, Aorta; PA, pulmonary artery; VSD, ventricular septal defect.
