Surgical Management
Published in Takahiro Shiota, 3D Echocardiography, 2020
Regarding adult congenital disease in general, see Chapter 16. As for the surgical contribution of 3D echocardiography in this field, routine use of 3D echocardiography was reportedly feasible and valuable for some types of congenital heart disease. Surgeons found the 3D images helpful for providing a realistic and almost specimen-like preview of the surgical anatomy that facilitates planning of the surgical program.16,17 In a more recent report, 3D printing or 3D printed models did not change the surgical decision in most cases of complex congenital heart disease (21 of 40 cases, 52.5% cases). However, in 19 of the 40 selected complex cases, 3D printed models helped redefine the surgical approach.18 3D printing with and without 3D TEE may benefit surgery for CHD because of the individual complexities of the cardiac anatomy.
Ultrasound assessment of endometriosis

Combined with modern transducer (TVS) technology, it provides increased, high-resolution anatomical information within the pelvis. Its principal advantage in diagnostic terms is the ability to obtain any anatomical plane within the body and to visualise the ultrasound information in the form of a multisectional display (See Figure 10.2b). 3D can involve other imaging formats (see ‘Single Sweep Technology’), but from a practical and diagnostic point of view, multisectional displays remain the most useful in this area of medical ultrasound. 3D images can be viewed as a static format or in real-time (i.e. 4D ultrasound), but the latter offers little benefit in gynaecological applications. Figures 10.10–10.12 demonstrate the value of the 3D TVS multisectional facility, including both G-S and CDI techniques. Figure 10.12 in particular highlights the diagnostic value of 3D multi-sectional displays in assessing complex features associated with severe, extensive endometriosis.

Complex simulation that used intelligent techniques became available for training medical practitioners. Intelligent inferring of images and data facilitated automated detection of cancers and other abnormalities. Using intelligent techniques in data and process analysis is making life convenient for medical practitioners. Database integration is well established, and the information retrieval and interaction have become web-based. Physicians have started experimenting with virtual and augmented reality to visualize and interact with 3D regions of interest before performing surgery.

Using a projector, the Neurotracker’s three-dimensional interface was presented to the participants wearing active 3D glasses and seated 1.5 meter from a 60-inch screen. Referring to Figure 2, a Neurotracker trial consists of the following five steps: a) eight balls of similar shape and color are randomly arranged in the Neurotracker interface: participants are encouraged to fixate a dot in the center of the projection throughout the assessment; b) four balls which are identified as the targets to be tracked during the trial become highlighted for a few seconds; c) targets return to their original appearance as a period of random movement lasting a total of 8 seconds begins; d) the participant must identify the targets through the distractors; e) feedback on trial performance is visually provided to the participant. The CORE assessment mode, being the most widely utilized in the Neurotracker literature, was selected (42–52). A series of 20 trials corresponds to one session and each laboratory encounter a total of three sessions. Each session provides a measure of performance on the task, known as speed threshold, a measure of visual perceptual skills in meters per seconds. The speed at which targets move within the 3D environment depends on participants’ performance and varies according to Levitt’s staircase theory (53). A positive response causes the balls (targets and distractors) to move faster, while an incorrect response reduces the speed of the next trial (37,49). A two-minute break was provided to participants between sessions, until three speed thresholds were obtained.
Interventions in Congenital Heart Disease: A Review of Recent Developments: Part II
Published in Structural Heart, 2021
Recently, patient-specific computational models have been developed for prediction of procedural outcomes. Using of simulation methodologies such as finite-element (Abaqus/Explicit, Dessault Systemes, RI, USA) and computational fluid dynamics (Fluent, Ansys, Canonsburg, USA), the anatomic and hemodynamic effects of interventions such as PPVI and coarctation stenting can be modeled by virtually deploying devices within the reconstructed surface anatomies.136 For each intervention, modeling of different device sizes or multiple devices and deployment configuration allows feasibility testing within the patient-specific anatomy.136 As such, anticipation of potential adverse events can minimize periprocedural complications or alter device choice and management decisions. Caimi et al. studied the differential impact of RVOT stenting on various calcification patterns in conduits to predict the risk of coronary artery compression, stent fracture, conduit injury, or arterial distortion. With this information, anticipatory strategies such as implantation of a covered stent or changes in deployment position can be envisioned.137 Ultimately, conventional development factors such as accuracy, practicality, portability, and cost-effectiveness will determine the future of these 3D visualization platforms in routine clinical practice.
The devil is in the details: developing a modern methodology for detailed medical illustrations

One recorded benefit of the Pernkopf Atlas is its detailed neuroanatomical depictions (Baker, 2019). Neuroanatomy is often documented as one of the more difficult subjects to learn in anatomy. Three-hundred eighty-three students from a variety of medical and anatomical backgrounds were surveyed on their existing perceptions of neuroanatomy; 33.3% of students ranked ‘appreciation of 3D relationships’ as significantly important to their understanding (Javaid, Chakraborty, Cryan, Schellekens, & Toulouse, 2018, p. 87). Additionally, the questionnaire asked students to comment on the importance of different teaching methods; 3D reconstructional videos ranked sixth out of the 15 methods students could choose (Javaid et al., 2018, p. 89). The increased use of digital 3D models in education and medical practice, along with the positive reception of study participants, indicates that 3D visualisation plays an integral part of developing new visualisation techniques (Crafts et al., 2017; Kockro et al., 2015; Maniam et al., 2020).
