What are the recommended techniques and associated complications for measuring pressure gradients in children with suspected aortic stenosis?
Percutaneous puncture of the left ventricle is recommended for measuring pressure gradients in children with suspected aortic stenosis when retrograde catheterization fails.
Offers potential option for gradient measurement in pediatric aortic stenosis after failed retrograde access; hypothesis-generating and should not yet change practice.
This paper is concerned with the techniques employed in determining the gradient, and hence the degree of stenosis, across the aortic valve in children in whom aortic stenosis is suspected. Experience gained in the investigation of a large series of children is reported, including the failure rate, the minor complications encountered, and the means whereby these may be prevented. The authors recommend percutaneous puncture of the left ventricle when retrograde catheterization via a peripheral artery is unsuccessful.

FINDLAY et al. (1965) conducted an observational in Aortic stenosis. Percutaneous puncture of the left ventricle vs. Retrograde catheterization via a peripheral artery was evaluated on Failure rate and minor complications. Percutaneous puncture of the left ventricle is recommended for measuring pressure gradients in children with suspected aortic stenosis when retrograde catheterization is unsuccessful.
