INOVA-2023-124

Background Information

Tetralogy of Fallot is characterized by four specific heart abnormalities (a ventricular septal defect, pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta). These defects prevent enough oxygen-rich blood from reaching the body. Surgical repair of these defects is associated with an increased risk for sustained ventricular arrhythmia and sudden cardiac death. This study aims to compare outcomes of patients who undergo electrophysiologic assessment and ablation of abnormal heart muscle signals to those who do not undergo such procedures.
