Right ventricular hypertension and ventricular arrhythmias are risk factors for sudden death after correction of tetralogy of Fallot, but sustained ventricular tachycardia has been reported only in patients without residual hemodynamic abnormalities. A patient with right ventricular hypertension and hypotensive ventricular tachycardia tolerated the arrhythmia better after relief of right ventricular outflow tract obstruction. This case provides insight into the relationship between hemodynamic abnormalities and the clinical consequences of arrhythmias. To our knowledge, it is the first report of ventricular tachycardia originating in scar adjacent to the ventricular septal defect patch after correction of tetralogy of Fallot.
