RV infundibular dilatation may flag persistent pressure overload post-tetralogy repair; leaves open its diagnostic utility versus catheterization in larger cohorts.
Dilatation of the right ventricular infundibulum on imaging is a reliable indicator of persistent outflow obstruction or VSD reopening after Fallot's tetralogy repair, though recatheterisation remains necessary to confirm residual stenosis.
Anderson et al. (1965) studied this question.
