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, p < 0.0001), but moderate correlation in measurements of the length ((b) r = 0.653, 95% confidence interval 0.356–0.830, p < 0.0003) and aortic side diameter of the PDA ((c) r = 0.704, 95% confidence interval 0.435–0.858, p < 0.0001) between them. AoG, aortography; CCT, cardiac computed tomography; ICE, intracardiac echocardiography; PA, pulmonary artery; PDA, patent ductus arteriosus.
