[Interauricular communications of the secundum type. Echocardiographic follow-up of the surgical correction].
A retrospective study was conducted on the pre- and post-operative electrocardiographic findings in 31 patients aged between 2 and 19 years who were operated for a secundum type of interventricular defect over a period of two years. Immediately after the surgical correction, the left ventricle dilates and returns to a normal size. The right ventricle gradually decreases in size and continues to decrease as the child grows, until a normal size is reached. However, the septum may continue to present abnormal movements despite the return to normal of the ventricular cavities. An alteration in this normal progression involving a RVd/LVd ratio greater than 1 and a RVd/RVd + LVd ratio identical to the pre-operative conditions is suggestive of a persistent shunt, despite the attempted surgical correction.
