End‐Organ Function and Exercise Performance in Patients With Fontan Circulation: What Characterizes the High Performers?

摘要

The physiologic hallmarks of the Fontan circulation—chronically elevated central venous pressures and low cardiac output—have significant effects not only on cardiovascular status but also impact other organ systems. Exercise capacity is limited in many and declines with age, accelerating in adolescence, but with wide variability. We explore the relationship between exercise performance and end‐organ function in outpatient subjects with a Fontan circulation.
