Personalized Patch for HLHS
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to improve heart surgery for newborns with a serious condition where part of the heart is underdeveloped. The research focuses on using 3D printing and advanced imaging to create personalized patches, known as Personalized Patch Templates, that fit perfectly. These patches help the heart grow properly and function better over time. This approach could make surgeries shorter and more effective, while ensuring consistent results among different surgeons. Newborns up to 2 months old who require a specific heart surgery and have family consent are suitable candidates for this trial. As an unphased trial, this study offers a unique opportunity to contribute to pioneering research that could revolutionize heart surgery for newborns.
Do I need to stop my current medications for the trial?
The trial information does not specify whether participants need to stop taking their current medications.
What prior data suggests that this personalized patch template is safe for neonatal heart surgery?
Studies have shown that the custom-made patch for heart surgery is generally well-tolerated by patients with conditions like HLHS (Hypoplastic Left Heart Syndrome). This patch aids surgeons in achieving the best fit during surgery by using 3D printing to tailor it to each patient's needs. Although specific safety data from clinical trials is not detailed, this technology emphasizes precision, which can improve outcomes.
Patients with similar conditions have successfully used engineered patches, and reports suggest that side effects are manageable. This personalized approach aims to enhance surgical accuracy, making the procedure easier and potentially safer. As this is a new method, ongoing follow-up will help determine the patch's effectiveness as the child grows.12345Why are researchers excited about this trial?
Unlike the standard surgical options for HLHS, which often involve generic patches, the Personalized Patch Template is unique because it uses a custom approach. Researchers are excited about this treatment because it leverages each patient's pre-operative imaging to design a tailored aortic arch configuration. This personalized modeling ensures a better fit and potentially improves surgical outcomes by reducing pressure on adjacent structures. The use of computer-aided design and 3D printing to create sterilizable, patient-specific patches represents a significant advancement over traditional methods, promising more precise and effective repairs.
What evidence suggests that this personalized patch is effective for vascular reconstruction in HLHS?
Research has shown that personalized patches can greatly improve surgical outcomes for babies with heart conditions like Hypoplastic Left Heart Syndrome (HLHS) and aortic arch hypoplasia. In this trial, participants will receive a personalized patch template designed using their pre-operative imaging. Studies have found that a custom-made patch allows surgeons to rebuild the heart more accurately. This method helps restore normal blood flow and supports the heart's growth as the child grows. Additionally, advanced imaging and 3D modeling have demonstrated that these personalized patches fit better and aid in more effective heart healing. Early tests with these techniques are promising, as they may reduce surgery time and make results more consistent among surgeons.12345
Are You a Good Fit for This Trial?
This trial is for babies with aortic arch narrowing or underdevelopment, such as those with Hypoplastic Left Heart Syndrome (HLHS). It aims to help these infants by using a personalized surgical patch designed from 3D printed models of their hearts.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Pre-operative Assessment
Participants undergo a pre-operative contrast CT scan to design simulation models and identify the most ideal aortic arch configuration.
Surgery and Immediate Post-operative Care
Surgical reconstruction using a personalized patch template followed by immediate post-operative care including a research CT scan and 4D MRI scanning.
Follow-up
Participants are monitored for safety and effectiveness after surgery with routine post-operative tests and imaging at 4-6 months.
What Are the Treatments Tested in This Trial?
Interventions
- Personalized Patch Template
Trial Overview
The intervention being tested is the use of a graphically designed patient-specific patch for reconstructing the aortic arch in newborns. The study involves creating and testing various engineered patches on heart models before applying them in actual surgeries.
How Is the Trial Designed?
1
Treatment groups
Experimental Treatment
Using each participant's pre-operative imaging, the most ideal aortic arch configuration will be identified. This will be followed by simulation of mechanical effects on the adjacent structures by overlapping the designed aortic arch model on the participant's original images. Computer-aided design of the personalized patch template will then be completed and followed by 3D printing of the sterilizable, personalized patch template.
