Predicting Arrhythmogenic Risk in Congenital Heart Patients: the PRECISION Study
- Conditions
- Congenital Heart DiseaseArrhythmia in Children
- Interventions
- Diagnostic Test: Provocative electrophysiology study
- Registration Number
- NCT04768634
- Lead Sponsor
- Boston Children's Hospital
- Brief Summary
In this research study we want to learn more about abnormal heart rhythm after cardiac surgery in children. These abnormal heart rhythms, also called arrhythmias, may occur due to several reasons after cardiac surgery. They can be due to abnormal electrical pathway or an irritable area of the heart that stimulates abnormal impulses. Regardless of the cause, arrhythmias after cardiac surgery can be a problem, extending the hospital stay, requiring additional medications and even leading to cardiac arrest.
Current practice is to monitor for arrhythmias after cardiac surgery, and to treat them if they occur. With this research, we want to investigate whether we can identify patients who will develop arrhythmia, and treat them before they occur.
- Detailed Description
This is a prospective, randomized controlled trial of provocative electrophysiology testing and prophylactic treatment of inducible SVT versus expectant management
