Key result
Conduction system pacing was successfully performed using delivery tool modifications to allow stability on the basal septum for deployment to the distal His bundle and proximal left bundle branch.
Why the study?
Data on conduction system pacing in adults with congenital heart disease remain limited, and the altered anatomy after a double switch operation requires modified tools and techniques.
Case Report
Demonstrates the feasibility of conduction system pacing in complex congenital heart disease (ccTGA post-double switch) via delivery tool modification to navigate altered anatomy.

Tool modifications enabled conduction system pacing in complex congenital heart disease; hypothesis-generating and should not yet change practice.
The use of conduction system pacing (CSP) in adults with congenital heart disease (CHD) is growing, however data remain limited. In patients with congenitally corrected transposition of the great arteries following the double switch operation, existing CSP tools and techniques require modification to allow for the anterior displacement of the atrioventricular node and proximal conduction system in addition to navigating the tortuous route of the atrial redirection. We report the successful use of CSP focusing on the technique of delivery tool modification to allow stability on the basal septum for deployment to the area of the distal His bundle and proximal left bundle branch.
