Figure 14.

Selected cine frames from right ventricular (RV) cineangiogram in posterio-anterior (A) and lateral (B) views in a neonate with pulmonary atresia with intact ventricular septum. RV outflow tract ends blindly and the atretic pulmonary valve (APV) (thick arrows) is shown. The RV is moderately hypoplastic, but tripartite. Tricuspid regurgitation is noted with opacification of the right atrium (RA). The catheter (C) is curled in the RA; the balloon tip is marked with thin arrow in both (A) and (B). UAC, umbilical artery catheter; UVC, umbilical venous catheter. Reproduced from Rao, P.S. Neonatal Catheter Interventions.
