Key result
After the Fontan procedure, the ratio of forward flow during atrial systole to total area was higher in patients with tricuspid atresia than single ventricle (0.54 vs 0.45, p<0.01).
Why the study?
Are there differences in pulmonary artery flow dynamics after the Fontan procedure between patients with tricuspid atresia and those with single ventricle?
Observational (n=20)
Are there differences in pulmonary artery flow dynamics after the Fontan procedure between patients with tricuspid atresia and those with single ventricle?
Absolute Event Rate: 0.54% vs 0.45%
p-value: p=<.01
Flow dynamics in the pulmonary artery after the Fontan procedure differ significantly between patients with tricuspid atresia and single ventricle, with tricuspid atresia patients showing higher atrial systolic forward flow.
No takes yet. Share an insight, caveat, or question.
Pulmonary flow differences after Fontan by anatomy should not yet change practice; leaves open effects on outcomes.
Nakazawa et al. (1987) conducted an observational in Tricuspid atresia or single ventricle after Fontan procedure (n=20). Tricuspid atresia vs. Single ventricle was evaluated on Ratio of forward flow during atrial systole to total area (Fa) (p=<.01). After the Fontan procedure, the ratio of forward flow during atrial systole to total area was higher in patients with tricuspid atresia than single ventricle (0.54 vs 0.45, p<0.01).
