Sixty‐six patients operated on previously for coarctation of the aorta were included in the study. There were 50 children and 16 adults. Invasive and non‐invasive gradients were recorded. Anatomical obstruction was evaluated by angiography in 54 patients and the numbers and size of collaterals were quantified. The closest correlation was found between Doppler‐estimated gradients and invasive peakinstantaneous gradients ( r = 0.87). The relation between anatomical obstruction and invasive peak‐to‐peak gradients, Doppler gradients and diastolic flow were discouraging ( r ‐ 0.64, 0.54 and 0.35). Liberal indications for angiography or magnetic resonance tomography are recommended.
