Feasibility, Reproducibility, and Prognostic Value of Exercise Echocardiography for Cardiac Output Reserve Assessment in Fontan Physiology
Patients with Fontan palliation had lower CO reserve, and impaired CO reserve was associated with congestion and cardiovascular events. Further studies are required to determine whether cardiac interventions can improve CO reserve and whether changes in CO reserve can be used as a surrogate end point for therapeutic response.
