Keywords: Flow, Vessels
Motivation: There is currently limited data examining longitudinal changes in hemodynamics and vascular properties in Fontan patients living at altitude.
Goal(s): We aimed to assess hemodynamic parameters and vessel morphology in Fontan patients at a single high-altitude surgical center and assess correlations between these parameters and post-Fontan outcomes.
Approach: We retrospectively reviewed patients undergoing Fontan operation from 1999 to 2021. We analyzed data from cardiac magnetic resonance imaging and cardiac catheterization.
Results: Our findings highlight post-Fontan changes in flow, pressure, and area. The changes in systemic and caval flow, along with pressure variations, offer insights into the effects of Fontan circulation.
Impact: This study advances our understanding of Fontan circulation at high-altitude, paving the way for improved prognostic information and long-term outcomes in this patient population.
