Catheter positions in congenital cardiac malformations.

Biplane cineangiocardiograms were examined from a population of patients with diverse forms of congenital heart disease and examples were selected to illustrate catheter positions which may help define and elucidate the anatomy of simple and complex cardiac lesions. Familiarity with the appearance of these typical and atypical catheter positions may be of considerable aid in the course of hemodynamic study and in the evaluation of cineangiocardiograms. The editors suggest that each figure be evaluated as an unknown before reading the caption.
