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.
Miranda et al. (Fri,) studied this question.
