Key result
CardioMEMs reveals marked peak mPAP increases during exercise in pediatric Fontan patients.
Why the study?
Assessment of Fontan pressures during exercise has been previously challenging in pediatric patients with Fontan circulation.
Does an implanted hemodynamic monitor (CardioMEMs) provide useful assessment of Fontan pressures during exercise in pediatric patients with Fontan circulation?

Does an implanted hemodynamic monitor (CardioMEMs) provide useful assessment of Fontan pressures during exercise in pediatric patients with Fontan circulation?
Implanted hemodynamic monitors (CardioMEMs) can be successfully utilized to assess Fontan pressures during exercise in pediatric patients, potentially guiding clinical management.
Implanted monitors may inform exercise management in select Fontan cases; leaves open validation in prospective trials.
Assessment of Fontan pressures during exercise has been previously challenging. We report our experience with 4 children, in whom implanted hemodynamic monitor was utilized to assess Fontan pressures during exercise. Data was used to modify treatment in one case. The device provided useful insight into exercise-related changes in Fontan patients.

Sabati et al. (2024) conducted a case report in Fontan circulation (n=4). Implanted hemodynamic monitor (CardioMEMs) was evaluated on Mean pulmonary artery pressure (mPAP) during exercise. The CardioMEMs implanted hemodynamic monitor successfully measured Fontan pressures during exercise in 4 pediatric patients, revealing a marked rise in mean pulmonary artery pressure at peak exercise.
