Filling pressures in Fontan revisited: Comparison between pulmonary artery wedge, ventricular end-diastolic, and left atrial pressures in adults

Pulmonary artery wedge pressure (PAWP) has been shown to correlate better with left atrial pressure (LAP) than ventricular end-diastolic pressure (VEDP) in acquired heart disease. The correlation between VEDP and PAWP and their performance as surrogates for LAP in Fontan patients is unknown.Offline single-beat simultaneous measurement of PAWP and VEDP was performed in 50 adult Fontan patients and non-simultaneous hemodynamic data abstracted for...
