Prefabricated Dacron baffle for use in correction of transposition of the great arteries.

Interatrial venous transposition for correction of transposition of the great arteries (TGA) is facilitated by using a premolded Dacron baffle. Fine-mesh Dacron is easily fashioned to the desired shape in a metallic brass mold at 200 degrees C. The resultant baffle material can be autoclaved without losing its shape or altering the fabric characteristics of flexibility and porosity. This premolded baffle has been used in our last 7 patients with TGA over the past two years without complication, and the use of Dacron in 13 survivors over the past seven years has shown no pulmonary or venous obstructions related to the material.
