Abstract
BACKGROUND Three-dimensional printing is increasingly utilised for congenital heart defect procedural planning. CT or MR datasets are typically used for printing, but similar datasets can be obtained from three-dimensional rotational angiography. We sought to assess the feasibility and accuracy of printing three-dimensional models of CHD from rotational angiography datasets. METHODS Retrospective review of CHD catheterisations using rotational angiography was performed, and patient and procedural details were collected. Imaging data from rotational angiography were segmented, cleaned, and printed with polylactic acid on a Dremel® 3D Idea Builder (Dremel, Mount Prospect, IL, USA). Printing time and materials' costs were captured. CT scans of printed models were compared objectively to the original virtual models. Two independent, non-interventional paediatric cardiologists provided subjective ratings of the quality and accuracy of the printed models. RESULTS Rotational angiography data from 15 catheterisations on vascular structures were printed. Median print time was 3.83 hours, and material costs were $2.84. The CT scans of the printed models highly matched with the original digital models (root mean square for Hausdorff distance 0.013 ± 0.003 mesh units). Independent reviewers correctly described 80 and 87% of the models (p = 0.334) and reported high quality and accuracy (5 versus 5, p = NS; κ = 0.615). CONCLUSION Imaging data from rotational angiography can be converted into accurate three-dimensional-printed models of CHD. The cost of printing the models was negligible, but the print time was prohibitive for real-time use. As the speed of three-dimensional printing technology increases, novel future applications may allow for printing patient-specific devices based on rotational angiography datasets.

[PMID: 35527744 PMCID: PMC9075573 DOI: 10.4103/apc.apc_111_18] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2018] [Revised: 10/11/2018] [Accepted: 08/16/2021] [Indexed: 11/04/2022] Open
Abstract
Pulmonary arteriovenous malformation (PAVM) is an abnormal communication between the pulmonary artery and the pulmonary vein. PAVMs are usually congenital in origin; however, they may be acquired. Three-dimensional rotational angiography (3DRA) is a technique used increasingly for imaging in congenital heart disease but to our knowledge has never been used in imaging and planning device closure of PAVM. We describe the use of 3DRA technique for imaging and planning device closure of PAVMs and discuss the advantages of this modality. 3DRA is an excellent tool for imaging of various vascular anomalies. It provides high-quality accurate images through a quick and safe procedure, it is also very useful in planning interventional procedures in PAVM, as it clearly delineates all feeders to PAVM and gives an exact view for analysis and intervention.

Abstract
OBJECTIVES The purpose of this study was to investigate the influence of simulated reduced-dose three-dimensional angiography (3DA) on the accuracy and precision of linear measurements derived from 3DA datasets. BACKGROUND Three-dimensional angiography is performed during X-ray guided interventional procedures to aid diagnosis and inform treatment strategies for children and adults with congenital heart disease. However, 3DA contributes substantially to patient radiation dose and may lead to an increased radiation-induced cancer risk. METHODS Reduced-dose patient 3DA images were simulated by adding quantum noise to the 2D projection angiograms, then reconstructing the projection angiograms into the 3DA dataset. Dose reduction in the range 33-72% was simulated. Five observers performed 46 vessel diameter measurements along prespecified axes within 23 vessel segments from 11 patient 3DA datasets. Statistical tests were performed to assess the influence of radiation dose reduction on the accuracy and precision of vessel diameter measurements. RESULTS Vessel diameter measurements were in the range 5.9- 22.7 mm. Considering all vessel segments and observers, the influence of dose level on the accuracy of diameter measurements was in the range 0.02 - 0.15 mm (p .05-.8). Interobserver variability increased modestly with vessel diameter, but was not influence by dose level (p = .52). The statistical test for observer recall bias was negative (p = .51). CONCLUSIONS Simulated dose reduction up to 72% did not affect the accuracy or precision of the diameter measurements acquired from 3DA images. These findings may embolden 3DA radiation dose reduction for pediatric and congenital heart disease patients.

Abstract
Three-dimensional rotational angiography (3D-RA) enables volumetric imaging through rotation of the C-arm of an angiographic system and real-time 3D reconstruction during cardiac catheterization procedures. In the field of congenital heart disease (CHD), 3D-RA has gained considerable traction, owing to its capability for enhanced visualization of spatial relationships in complex cardiac morphologies and real time image guidance in an intricate interventional environment. This review provides an overview of the current applications, strengths, and limitations of 3D-RA acquisition in the management of CHD and potential future directions. In addition, issues of dosimetry, radiation exposure, and optimization strategies will be reviewed. Further implementation of 3D-RA will be driven by patient benefits relative to existing 3D imaging capabilities and fusion techniques balanced against radiation exposure.

Abstract
Cardiac catheterization is a commonly used form of imaging and treatment in pediatric patients with congenital heart disease. Traditionally, two-dimensional conventional angiography was the method used, but since 2000 three-dimensional rotational angiography (3DRA) is increasingly used in the field of cardiology in both adult and pediatric patients. To investigate the use and applications of 3DRA in pediatric congenital cardiology, literature was systematically reviewed and 29 eligible articles were found. Those showed that 3DRA is already a greatly valued diagnostic and therapeutic technique in pediatric cardiology. However, the literature misses well-designed clinical, homogeneous, multicenter, prospective studies recording data in a standardized manner. These studies are necessary to ensure proper data analysis and to investigate the true advantages of 3DRA and how it exactly benefits the patients.

Abstract
Background The use of three-dimensional rotational angiography (3D-RA) to assess patients
with congenital heart diseases appears to be a promising technique despite the
scarce literature available. Objectives The objective of this study was to describe our initial experience with 3D-RA and
to compare its radiation dose to that of standard two-dimensional angiography
(2D-SA). Methods Between September 2011 and April 2012, 18 patients underwent simultaneous 3D-RA
and 2D-SA during diagnostic cardiac catheterization. Radiation dose was assessed
using the dose-area-product (DAP). Results The median patient age and weight were 12.5 years and 47.5 Kg, respectively. The
median DAP of each 3D-RA acquisition was
1093µGy.m2 and
190µGy.m2 for each 2D-SA acquisition
(p<0.01). In patients weighing more than 45Kg (n=7), this difference was
attenuated but still significant (1525 µGy.m2
vs.413µGy.m2, p=0.01). No difference
was found between one 3D-RA and three 2D-SA
(1525µGy.m2 vs.1238
µGy.m2, p = 0.575) in this population. This
difference was significantly higher in patients weighing less than 45Kg (n=9)
(713µGy.m2
vs.81µGy.m2, P = 0.008), even when comparing
one 3D-RA with three 2D-SA (242µGy.m2,
respectively, p<0.008). 3D-RA was extremely useful for the assessment of
conduits of univentricular hearts, tortuous branches of the pulmonary artery, and
aorta relative to 2D-SA acquisitions. Conclusions The radiation dose of 3D-RA used in our institution was higher than those
previously reported in the literature and this difference was more evident in
children. This type of assessment is of paramount importance when starting to
perform 3D-RA.

Abstract
AIMS Three-dimensional rotational angiography (3DRA) is a relatively new but promising imaging technique in the paediatric catheterization laboratory. However, data on effective dose (ED) of this technique in children are lacking. The purpose of this study is to provide ED of 3DRA and to correlate this with parameters readily available in daily practice. Furthermore, the effect of dose-reducing techniques is evaluated. METHODS AND RESULTS Effective doses were calculated with Monte Carlo PCXMC 2.0 in 14 patients who underwent a total of 17 3DRAs at our paediatric catheterization laboratory. Median age was 5.7 years (range 1 day-16.6 years). Median ED was 1.6 milliSievert (mSv) (range 0.7-4.9). Effective dose did not correlate with age and body surface area but did correlate with dose area product (DAP) and milliGray (mGy) with r(2) of 0.75 and 0.83, respectively. Reduction of the total amount of frames from 248 to 133 per rotation resulted in further dose reduction of over 50% with preserved image quality. CONCLUSION The median ED of 3DRA in children is 1.6 mSv and correlates with DAP and mGy. This dose can be halved by applying frame reduction. A significant further dose reduction can be achieved by obtaining additional knowledge of the equipment used.

Abstract
PURPOSE OF REVIEW To provide an overview of the various modalities that have emerged in the last years as adjunctive tools to provide detailed imaging of the cardiovascular system in the catheterization laboratory. RECENT FINDINGS Completion angiography after cardiac surgery for congenital heart disease using a dedicated hybrid operating cardiac suite may aid in early diagnosis and therapy of postsurgical abnormalities. The application of three-dimensional rotational digital angiography results in a more precise delineation of the three-dimensional anatomy of vascular structures outside the heart with rapid image processing and reduction of the amount of contrast used and ionizing radiation dose. Combined catheterization/magnetic resonance (MR) hybrid laboratories have the potential to accurately assess changes in the anatomy and physiology pretranscatheter and posttranscatheter interventions. Fully MR-guided transcatheter procedures have become possible in animal models. Real-time three-dimensional transesophageal echocardiography (TEE) has helped to guide transcatheter procedures in septal and valvar structures. Miniaturization of probes has expanded the applications of TEE for smaller neonates. The use of intravascular ultrasound has helped to better understand the mechanisms of vascular diseases and transcatheter treatments. SUMMARY Knowledge and proper application of new imaging modalities during interventions in the catheterization laboratory may improve the outcomes of patients with congenital and acquired structural heart disease.
