What haemodynamic criteria define elevated values during exercise catheterization in adults post-Fontan?
PAWP >20 mmHg and mean PA pressure >25 mmHg can be used to define elevated exercise haemodynamics in adults post-Fontan, with abnormal physiology characterized by systemic venous hypertension and arterial desaturation.
PAWP >20 mmHg and mean PA pressure >25 mmHg could be used to define elevated values during exercise in adults post-Fontan. The major discrepancy in exercise haemodynamics among Group II compared to controls appears to be the degree of systemic venous hypertension and arterial desaturation.
