[Pre- and postoperative MRI study of 3 newborn infants with pulmonary atresia and interventricular communication]

The use of nuclear magnetic resonance in this study allowed complete and accurate pre- and postoperative follow-up on three newborn infants with pulmonary atresia and interventricular communication or extreme tetralogy of Fallot who had undergone systemic-pulmonary palliative surgical correction of the Blalock-Taussig type. The morphological and functional appearance of the surgical correction was well assessed and regular monitoring was possible of the permeability and calibre of the anastomosis and condition and progression of the pulmonary pathway. Nuclear magnetic resonance proved to be a promising means of examination in the postoperative follow-up of congenital cardiopathies.
