Use of 3‐D digital subtraction rotational angiography during cardiac catheterization of infants and adults with congenital heart diseases

Objective To compare image quality, radiation and contrast doses required to obtain 3D‐Digital subtraction rotational angiography (3D‐DSRA) with 3D‐Digital rotational angiography (3D‐DRA) in infants (children ≤ 2 years of age) and adults with congenital heart diseases (ACHD). Background 3D‐DRA can be performed with radiation doses comparable to bi‐plane cine‐angiography. However, 3D‐DRA in infants requires a large contrast volume. The resolution...
