Why the study?
Transvenous pacemaker implantation for sinus node dysfunction in Fontan palliation carries the challenge of identifying suitable pacing tissue and risking vascular obstruction in a low-flow circuit.

Should not yet change Fontan pacing practice; leaves open whether voltage mapping reliably guides durable transvenous leads.
Advanced mapping technologies such as electro-anatomic voltage mapping can be utilized to guide pacemaker implantation in patients with complex cyanotic heart disease.
Dasgupta et al. (2019) studied this question.
