Brief Summary

Introduction and Objective: In recent years, 3D (three-dimensional) modeling has been added to traditional and effective diagnostic methods such as Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Echocardiography. The purpose of this study is to determine the effectiveness of models created from patients' own radiological images using 3D printing technology in the clinical setting to simulate surgery in the preoperative period and provide preoperative parental education to improve family quality of life and positively influence patient outcomes. Methods: The study is a two-group pretest-posttest randomized controlled study. The children who come to the outpatient clinic examination in a private hospital and who are subjected to Computed Tomography (CT) examination for diagnostic procedures will be modeled in the experimental group, pre-tests will be applied, and the model will be 3D printed after it is approved by the radiologist who is among the researchers. The sample size is 15 experimental group and 15 control group. After the radiologist's approval, surgical simulation and preoperative education will be applied to the experimental group. The control group will receive the same parent education as the standard model. Both groups will complete the Sociodemographic Information Form, Surgical Simulation Evaluation Form - Part I, and Pediatric Quality of Life Inventory (PedsQL) Family Impacts Module one week prior to hospitalization. Surgical simulation and preoperative education will be completed on the same day. On postoperative day 0, only the Surgical Simulation Evaluation Form - Part II will be applied and on postoperative day 15, the Surgical Simulation Evaluation Form - Part II and the Pediatric Quality of Life Inventory (PedsQL) Family Impacts Module will be applied to both groups as a posttest. Pilot Study and Results: Modeling and 3D printing studies were conducted to carry out the study. A total of four diagnosed and treated patients were retrospectively analyzed. An intracardiac anomaly was detected in the patient data taken for the first model. It was decided to model the extracardiac structures since the inside of the heart was filled with blood, and the blood could not be ruled out as a solid structure. Finally, aortic coarctation was modeled clearly from the images taken and completed.

Outcome Measures

Primary Outcomes (4)

• Pretest-Family Impacts Module of the Pediatric Quality of Life Inventory PedsQL

  The Turkish validity and reliability study of this scale, first developed by Varni et al. in 2004, was conducted and published by Gürkan et al. in 2019 (Gürkan, Bahar, Çapık, Aydoğdu, \& Beşer, 2020; Varni, Sherman, Burwinkle, Dickinson, \& Dixon, 2004). The data on the sub-dimensions and Cronbach alpha values of this scale, which has 8 sub-dimensions in total, are as follows; physical (0.85), emotional (0.83), social (0.82), cognitive (0.86), communication (0.51), anxiety (0.79) activities of daily living (0.89), family relationships (0.95). A total score of 0.92 was reported. In addition, Cronbach alpha values for all subscales were also included in the original study. The scale does not have a cut-off point. A high score indicates a good family quality of life functioning, while a low score indicates a negative family quality of life. Within the scope of this study, a comparison between mean scores will be made.

Experimental

EXPERIMENTAL

Preoperative:Once the surgery date is set, appointments will be made with the surgeon for surgical simulation and with the family for education one week prior to surgery. The surgeon will be asked to complete the Surgical Simulation Evaluation Form-Part I. At the same time, another researcher will complete the family sociodemographic information form and PedsQL questions in the examination room. After completion of the pre-test and the surgical simulation, the families are given a 30-minute preoperative education with the "Congenital Heart Disease Parent Education Booklet", together with a life-size 3D heart model obtained from their child's own heart, and drawings on paper where they are not understood. Postoperative: After surgery, the patient will be followed until discharge, and only Part II of the Surgical Simulation Evaluation Form will be completed. On the 15th postoperative day, the Surgical Simulation Evaluation Form Part II and the PedsQL will be given again as a posttest.

Control Group

NO INTERVENTION

Preoperative:When the operation date is determined, one week before the operation, the patients included in the study's control group will be asked the Sociodemographic Information Form and Pediatric Quality of Life Inventory Family Module (PedQL) questions in the examination room. After the pretest, standardized education will be given to the families. The disease process will be explained to the patients with the same 'Congenital Heart Diseases Parent Education Booklet', and the disease process will be presented with the heart model used in standard medical faculty anatomy courses and the ununderstood parts will be detailed by drawing on paper. The remaining 15 minutes of the education will be conducted as a question and answer with the parents. Postoperative:After the operation, the Surgical Simulation Evaluation Form Part II and PedsQL will be filled out again as post-tests for this group.

Interventions

Surgical Simulation with 3D Heart Model and Parental Education with "Congenital Heart Disease Parent Education Booklet" and tailored 3D Heart Modeling OTHER

The first step in the modeling process is masking. For this study, the average minimum value for masking ventricles and large vessels was set between 80 and 200 HU (Brüning et al., 2022). Threshold values of min 216 HU - max 1502 HU are used. At these HU values, the blood in the heart and great vessels is masked and the outline of the heart is revealed. Lowering the minimum HU value is necessary to make the heart walls more visible. However, this results in masking unwanted soft tissues other than the heart, such as muscle and fat. The masked unnecessary surrounding tissues are removed first with the cropping mask and then manually by marking along the contours of the heart and great vessels. Thus, a model containing only the heart and the desired large vessels will be created and cleaned from the surrounding tissues. With this mask, 3D reconstruction will be performed, and the model will be ready for printing.

Experimental

Eligibility Criteria

• Age: 0 Years - 18 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• The participant has a congenital heart disease between the ages of 0-18 years, the congenital defect has extracardiac structure malformations (This is because the modeling is to be done before the operation is done in a shorter time, and it is desired to be trained for preoperative education). Hollow modeling requires more detailed technique and time (Bhatla et al., 2017). In addition, the difficulty of 3D printing the hollow model made in the pilot study was also effective in this decision),
• Being a candidate for elective surgery,
• Having a contrast-enhanced CT image taken during and before the patient's routine diagnostic procedure outside the scope of the study,
• Having at least 15 days between the imaging and the surgical procedure plan,

You may not qualify if:

• Patients who do not require CT for diagnosis or treatment (no patient will undergo CT imaging within the scope of the study unless necessary for this study only),
• Emergency surgical procedures, heart defects involving intracardiac structures (Atrial Septal Defect, Ventricular Septal Defect, Tetralogy of Fallot),
• Additional anomalies/syndromes,
• Chronic diseases (such as neurodevelopmental disorders, bleeding disorders, asthma, or Down syndrome),
• History of cardiac arrest, contrast agent reflection in the images,
• Image quality preventing modeling.

Model Details: This study will be conducted in two hospitals affiliated with a foundation in Istanbul, located in the Marmara Region of Turkey. The imaging used in this study, including patients examined and diagnosed by the pediatric cardiology specialist doctor from the researchers involved, will be checked with a specialist radiology doctor in another hospital belonging to the same foundation. Patients included in the study will be determined with images that can be modeled and meet the inclusion and exclusion criteria. The target sample will include parents of children scheduled to undergo cardiac surgery. The study will be explained to the legal guardian/parent of the identified volunteer patients, and those who wish to participate and give written consent will be included.
