Cardiovascular magnetic resonance in the assessment of repaired tetralogy of Fallot

Significant advances in the management of congenital heart disease (CHD) over recent decades have resulted in marked improvements in the quality and length of life in this patient group. Approximately 85% of infants with congenital cardiovascular abnormalities are now expected to reach adulthood . The resulting increase in number of adult CHD patients  poses new challenges in terms of facilities, medical expertise, and disease management, especially in the more complex CHD groups, who require meticulous long-term follow-up and planning of care to pre-empt clinical deterioration and maintain quality of life.
This is particularly true of patients with tetralogy of Fallot (TOF), the commonest form of cyanotic CHD . The key feature of TOF is displacement of the outlet septum in a way that usually results in pulmonary and subpulmonary stenosis, a subaortic ventricular septal defect (VSD) and hypertrophy of the right ventricle (RV) . TOF can present with different...
