Correlation of ecg and cardiac mri for assessment of ventricular hypertrophy/dilatation in adults with congenital heart disease

The electrocardiogram (ECG) is universally utilised to assess chamber hypertrophy and dilatation, including in adults with congenital heart disease (ACHD). Complex ACHD patients (Tetralogy of Fallot, Transposition of the great arteries and single ventricle physiology) have a higher incidence of right and left bundle branch block patterns (RBBB/LBBB) on ECG and many have right ventricular hypertrophy/dilatation (RVH/RVD) or left ventricular hypertrophy/dilatation (LVH/LVD).
