A study by Parini et al published in Pediatric Cardiology. reports on the use of Rotational angiography (RA) for evaluating congenital heart disease (CHD) in the cardiac cath lab, permits acquisition of 3D datasets with superior spatial resolution. The authors describe five cases on whom they created 3D-printed hearts in patients with CHD.
Diagnoses included coronary artery aneurysm, Glenn shunt, coarctation of the aorta, tetralogy of Fallot with major aortopulmonary collateral arteries (MAPCAs), and pulmonary artery stenosis. There was no significant measurement difference between RA and the printed model (r = 0.990, p < 0.01). There was also no significant inter-observer variability.
The authors concluded that RA could generate highly accurate 3D models in congenital heart disease. These models can be useful in patient evaluation and management.
