Experiences with invasive cardiac catheterization in low birth weight infants
are few. In our clinic, we performed balloon aortic valvuloplasty by antegrade
approach in a neonate weighing 1100 g with critical aortic stenosis, patent
ductus arteriosus and atrial septal defect. The right femoral vein was accessed
with a 4 Fr sheath, and a catheter was placed into the left ventricle from
the atrial septal defect along the guidewire for coronary catheter. The aortic
valve was passed with guidewire, and the guidewire was placed into the
right arteria carotis. After proper placement, the balloon was inflated at
6 atm using an indeflator device until indentation disappeared. After the
procedure, the mean pressure gradient over the stenotic aortic valve was
measured as 18 mmHg, mild-moderate aortic insufficiency was noticed, and
left ventricle contraction was better. To the best of our knowledge, this is
the lowest weight infant in the literature to undergo successful antegrade
balloon aortic valvuloplasty.
