Transcatheter guidewire perforation of the pulmonary valve as a palliative procedure in pulmonary atresia with intact interventricular septum.

ABSTRACT

We report two cases of pulmonary atresia with intact interventricular septum in whom we successfully perforated and performed balloon dilation of the atretic pulmonary valve using a simple guidewire technique. The technical challenges of performing this procedure in small infants are highlighted.
