Key result
Percutaneous balloon dilatation and stenting of stenosed major aortopulmonary collaterals significantly increased mean arterial oxygen saturation from 75% to 82%.
Why the study?
Does percutaneous balloon dilatation and stenting improve pulmonary flow and oxygen saturation in patients with PA-VSD and stenotic MAPCAs?
Cohort (n=12)
No
Does percutaneous balloon dilatation and stenting improve pulmonary flow and oxygen saturation in patients with PA-VSD and stenotic MAPCAs?
Mean Difference: 7
Absolute Event Rate: 82% vs 75%
p-value: p=<0.001
Percutaneous balloon dilatation and stenting of stenosed MAPCAs in patients with PA-VSD is feasible, improves arterial oxygen saturation, and may facilitate subsequent surgical repair.
No takes yet. Share an insight, caveat, or question.
May support palliation in PA-VSD with stenotic MAPCAs; hypothesis-generating and needs prospective validation.
Brown et al. (1998) conducted a cohort in Stenotic major aortopulmonary collateral arteries in pulmonary atresia and ventricular septal defect (n=12). Balloon dilatation and stenting vs. Pre-procedure baseline was evaluated on Percutaneous arterial oxygen saturation (MD 7%, p=<0.001). Percutaneous balloon dilatation and stenting of stenosed major aortopulmonary collaterals significantly increased mean arterial oxygen saturation from 75% to 82%.
