Figure 22. Diagram demonstrating the reduction (P < 0.001) in the dimension of the left atrium (left panel) and left atrium to aortic root ratio (right panel) on the day after occlusion of the ductus arteriosus. During follow-up (FU), there was no further change (P > 0.1); these values continued to be decreased (P < 0.01) when compared to those before (Pre) ductal closure. LA/Ao: Left atrium to aorta; Post: on the day following ductal closure. Reproduced from Ref.[7].
