Summary: This week we review the impact of conduit size on exercise capacity in the single ventricle Fontan patient. Is there an optimal sized conduit for the Fontan patient? What is the role of formal exercise stress testing in the evaluation and monitoring of the Fontan patient? We review these questions and more with Associate Professor of Medicine at UT Southwestern - Dr. Ari Cedars. doi: 10.1007/s00246-019-02190-4
