Exercise MRI for Congenital Heart Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to better understand how the heart and muscles work together during exercise in children with heart conditions. Researchers will use MRI scans to observe blood flow and muscle function during physical activity. Children aged 10-18 who have had a heart transplant or have congenital heart disease and receive care at Stollery Children's Hospital may be suitable candidates.
As an unphased trial, this study offers participants a unique opportunity to contribute to valuable research that could enhance future care for children with heart conditions.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this MRI technique is safe for pediatric patients with heart disease?
Research has shown that Exercise MRI, which uses magnetic resonance imaging during exercise, is generally safe for assessing heart function. Studies have found that this method can be performed safely and reliably in various situations. For example, one study demonstrated that using a type of MRI called stress perfusion CMR is safe and provides valuable information about heart function.
Although these studies examined various heart conditions, they suggest that Exercise MRI itself does not cause significant harm or side effects. This method gathers important information about blood flow and heart health without requiring surgery. It is a well-tolerated option for assessing heart function, even in children with heart conditions.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it uses exercise MRI to assess cardiorespiratory fitness in children with heart disease, offering a non-invasive way to gather detailed information about heart function. Unlike standard tests like echocardiograms or stress tests, exercise MRI can provide comprehensive insights into how well the heart and lungs work together during physical activity. This could lead to better-tailored treatments and management strategies for young patients with heart disease, improving their quality of life and long-term outcomes.
What evidence suggests that Exercise MRI is effective for evaluating heart and skeletal muscle function in pediatric heart disease?
Research has shown that exercise benefits children with heart conditions, including those who have had heart transplants or were born with heart problems. Exercise can enhance their bodies' oxygen use and strengthen muscles. In this trial, participants will be divided into two groups: those who have received heart transplants and those with congenital heart disease. For children with congenital heart disease, exercise tests can identify those who might face more health issues. These findings suggest that exercise MRI, used to assess heart and muscle function during exercise, could offer crucial information for managing their heart health.678910
