Fontan operation linked to a ~193% higher rate of incoordinate ventricular relaxation versus unoperated patients.

May signal Fontan-related diastolic effects; leaves open prognostic impact in univentricular hearts.
Observational (n=26)
Does the Fontan operation affect regional wall motion of the systemic ventricle in patients with a univentricular atrioventricular connection?
Absolute Event Rate: 80% vs 27.3%
p-value: p=<0.01
The Fontan operation significantly increases incoordinate relaxation of the systemic ventricular wall, whereas incoordinate contraction is common both before and after the procedure.
Penny et al. (1991) conducted an observational in Univentricular atrioventricular connection (n=26). Fontan operation vs. Unoperated patients with a univentricular atrioventricular connection was evaluated on Incoordinate relaxation of the ventricular wall (p=<0.01). The Fontan operation was associated with a significantly higher rate of incoordinate relaxation of the ventricular wall compared to unoperated patients (80.0% vs 27.3%; p<0.01).
