Catheter Ablation in Adult Congenital Heart Disease

Catheter ablation is a minimally invasive procedure used to treat abnormal heart rhythms in adults with congenital heart disease. A thin, flexible tube called a catheter is inserted into a blood vessel and guided to the heart. Once in place, it delivers energy—such as heat or cold—to target and destroy specific faulty heart tissue that causes arrhythmias. This helps restore a normal heartbeat, reducing symptoms and improving quality of life. Because congenital heart conditions often create unique heart structures, the procedure is carefully planned to ensure safe and effective treatment tailored to each patient.
