Intracardiac Echocardiography as a Guide for Transcatheter Closure of Patent Ductus Arteriosus

Bland–Altman plots between the ICE and aortography or CCT. On the Bland–Altman plot, there were the greatest agreement in the PA side diameter between ICE and aortography or CCT ((a) mean bias 0.074 mm with 95% confidence interval −0.077 to 0.224), but moderate agreement in length ((b) mean bias 1.287 mm with 95% confidence interval −0.491 to 3.065) and poor agreement in the aortic side diameter ((c) mean bias 2.735 with 95% confidence interval 0.738 to 4.732) with statistically significantly higher value measured by aortography or CCTs (). AoG, aortography; CCT, cardiac computed tomography; ICE, intracardiac echocardiography; PA, pulmonary artery; PDA, patent ductus arteriosus.
