Complex Congenital Heart Disease

Planning corrective and palliative surgery for patients who have complex congenital heart disease often relies on the assessment of cardiac anatomy using two-dimensional noninvasive cardiac imaging modalities (echocardiography, cardiac magnetic resonance imaging, and computed tomography scan). Advances in cardiac noninvasive imaging now include the use of three-dimensional (3D) reconstruction tools that produce 3D images and 3D printouts. There is scant evidence available in the literature as to what effect the availability of 3D printouts of complex congenital heart defects has on surgical outcomes. Surgical outcomes of study subjects with a 3D cardiac printout available and their paired control subject without a 3D cardiac printout available were compared. We found a trend toward shorter surgical times in the study group who had the benefit of 3D models, but no statistical significance was found for bypass time, cross-clamp time, total time, length of stay, or respiratory support. These preliminary results support the proposal that 3D modeling be made readily available to congenital cardiac surgery teams, for use in patients with the most complex congenital heart disease.

AbstractObjective:The objective of this study was to evaluate the feasibility and effects of education on complex congenital heart diseases using patient-specific three-dimensional printed heart models.Methods:Three-dimensional printed heart models were created using computed tomography data obtained from 11 patients with complex congenital heart disease. Fourteen kinds of heart models, encompassing nine kinds of complex congenital heart disease were printed. Using these models, a series of educational hands-on seminars, led by an experienced paediatric cardiac surgeon and a paediatric cardiologist, were conducted for medical personnel who were involved in the care of congenital heart disease patients. Contents of the seminars included anatomy, three-dimensional structure, pathophysiology, and surgery for each diagnosis. Likert-type (10-point scale) questionnaires were used before and after each seminar to evaluate the effects of education.Results:Between November 2019 and June 2020, a total of 16 sessions of hands-on seminar were conducted. The total number of questionnaire responses was 75. Overall, participants reported subjective improvement in understanding anatomy (4.8 ± 2.1 versus 8.4 ± 1.1, p < 0.001), three-dimensional structure (4.6 ± 2.2 versus 8.9 ± 1.0, p < 0.001), pathophysiology (4.8 ± 2.2 versus 8.5 ± 1.0, p < 0.001), and surgery (4.9 ± 2.3 versus 8.8 ± 0.9, p < 0.001) of the congenital heart disease investigated.Conclusions:The utilisation of three-dimensional printed heart models for education on complex congenital heart disease was feasible and improved medical personnel’s understanding of complex congenital heart disease. This education tool may be an effective alternative to conventional education tools for complex congenital heart disease.

Abstract Aims Proof of concept and feasibility study for preoperative diagnostic use of mixed reality (MR) holograms of individual 3D heart models from standard cardiac computed tomography angiograms (CTA) images. Optimal repair for complex congenital heart disease poses high demands on 3D anatomical imagination. Three-dimensional printed heart models are increasingly used for improved morphological understanding during surgical and interventional planning. Holograms are a dynamic and interactive alternative, probably with wider applications. Methods and results A 3D heart model was segmented from CTA images in a patient with double outlet right ventricle and transposition of the great arteries (DORV-TGA). The hologram was visualized in the wearable MR platform HoloLens® for 36 paediatric heart team members who filled out a diagnostic and quality rating questionnaire. Morphological and diagnostic output from the hologram was assessed and the 3D experience was evaluated. Locally developed app tools such as hologram rotation, scaling, and cutting were rated. Anatomy identification and diagnostic output was high as well as rating of 3D experience. Younger and female users rated the app tools higher. Conclusion This preliminary study demonstrates that MR holograms as surgical planning tool for congenital heart disease may have a high diagnostic value and contribute to understanding complex morphology. The first users experience of the hologram presentation was found to be very positive, with a preference among the female and the younger users. There is potential for improvement of the hologram manipulation tools.
