Abstract 18441: 3d Printing is a Powerful Tool in the Management of Adult Patients With Congenital Heart Disease
Introduction: 3D printing is a promising technology that yields highly accurate replicas of a patient’s anatomy. We describe the use of 3D printing in adult patients with congenital heart defects (ACHD) for diagnosis, surgical planning, patient and trainee education.
Methods: Adult patients (> 18 years old) underwent cardiac CT or MRI (CMRI) for clinical evaluation. CMRI was performed on a 1.5 Tesla scanner with a 3D respiratory navigated inversion recovery FLASH sequence after 0.03 mmol/kg blood-pool gadolinium contrast, gadofosveset trisodium. Contrast-enhanced cardiac CT was performed on a 128 slice dual-source CT scanner using high-pitch spiral mode. Segmentation, post-processing and 3D printing were performed in collaboration with 3D Systems (3DS) - Healthcare (Golden, CO). Models were printed on a 3DS ProJet 660 color jet or Stratasys Eden260VS printer. Referring Cardiologists were surveyed about the utility of 3D models.
Results: 3D models were printed in eight ACHD patients (20 – 45 years) with a wide spectrum of congenital heart defects and vascular abnormalities (Table 1). 4/8 models were used for surgical planning, the remaining four for patient and trainee education (Figure 1). For 7/8 cases, referring Cardiologists reported the 3D models added value in understanding the patient’s heart disease over prior imaging evaluations. For the 4 cases printed for planning an intervention (surgery/interventional cath) all referring Cardiologists reported the model aided management decisions.
Conclusions: 3D printing adds value over conventional imaging in the management of ACHD patients. The models enhance patient management, surgical planning and education.
