“…More recently, Berman et al 21 described the usefulness of 3D-RA in patients previously undergoing cavopulmonary connections with a clear understanding of the mechanism of pulmonary stenosis 21 . The median DAP was 306 µ Gy.m 2 in this population with a median weight of 15.7Kg.…”

Background The use of three-dimensional rotational angiography (3D-RA) to assess patients with congenital heart diseases appears to be a promising technique despite the scarce literature available. Objectives The objective of this study was to describe our initial experience with 3D-RA and to compare its radiation dose to that of standard two-dimensional angiography (2D-SA). Methods Between September 2011 and April 2012, 18 patients underwent simultaneous 3D-RA and 2D-SA during diagnostic cardiac catheterization. Radiation dose was assessed using the dose-area-product (DAP). Results The median patient age and weight were 12.5 years and 47.5 Kg, respectively. The median DAP of each 3D-RA acquisition was 1093µGy.m2 and 190µGy.m2 for each 2D-SA acquisition (p<0.01). In patients weighing more than 45Kg (n=7), this difference was attenuated but still significant (1525 µGy.m2 vs.413µGy.m2, p=0.01). No difference was found between one 3D-RA and three 2D-SA (1525µGy.m2 vs.1238 µGy.m2, p = 0.575) in this population. This difference was significantly higher in patients weighing less than 45Kg (n=9) (713µGy.m2 vs.81µGy.m2, P = 0.008), even when comparing one 3D-RA with three 2D-SA (242µGy.m2, respectively, p<0.008). 3D-RA was extremely useful for the assessment of conduits of univentricular hearts, tortuous branches of the pulmonary artery, and aorta relative to 2D-SA acquisitions. Conclusions The radiation dose of 3D-RA used in our institution was higher than those previously reported in the literature and this difference was more evident in children. This type of assessment is of paramount importance when starting to perform 3D-RA.

The Fontan circulation is used as palliative surgery in the functionally univentricular heart. Due to the advances made in prenatal diagnosis, cardiac surgery, technology, and monitoring in complex congenital heart disease, survival rates have improved significantly. For this group of patients, the physiology and pathology remain challenging and eluding, even more so in the long-term follow-up. In the last decade pulmonary vascular resistance has been shown to be of utmost importance regarding cardiac output both at rest and during exercise. The aim of this article is to review the most recently published data, namely new concepts and our current understanding regarding the physiology; performance during exercise; the value of imaging modalities; and chronic liver pathology in the Fontan circulation.

The use of three‐dimensional rotational angiography to assess the pulmonary circulation following cavo‐pulmonary connection in patients with single ventricle

Abstract: 3DRA can be performed safely and effectively following CPC and may be more sensitive in diagnosing PA stenoses than 2D angiography. Quantitative measurements of PA diameter using 3DRA correlates well with 2D angiography.
