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

Figure 4

Correlations of measurements between the ICE and aortography or CCT. There was significantly highly positive correlation in measurements of the PA side diameter between ICEs and aortographies or CCTs ((a) r = 0.985, 95% confidence interval 0.967–0.993, ), but moderate correlation in measurements of the length ((b) r = 0.653, 95% confidence interval 0.356–0.830, ) and aortic side diameter of the PDA ((c) r = 0.704, 95% confidence interval 0.435–0.858, ) between them. AoG, aortography; CCT, cardiac computed tomography; ICE, intracardiac echocardiography; PA, pulmonary artery; PDA, patent ductus arteriosus.
