Introduction: In this study, we compared the real time echocardiogram data and angiographic measurements of Patent Ductus Areriosus (PDA).
Methods: There were 15 patients with PDA included in the study. All of them were done as an elective procedure. There were 5 males (33.33%) and 10 females (66.67%) whose ages ranged from 12 years to 33 years old (21.26±6.71). All patients underwent full 2D echocardiogram as well as real time three-dimensional echocardiogram (RT3DE). The measurements included are are the aortic end of the duct, the pulmonary end of the duct and the PDA length as well as the anatomical type of the PDA. The data obtained by RT3DE were compared against 2D echocardiogram and angiography.
Results: There was no significant difference between 3D echocardiography and angiography in measuring the pulmonary end using the paired t-test (t=0.770, p=0.458) and therefore there was a positive correlation between these two measurements (r=0.868, p=0.001). There was no significant differences between the length by 3D measurements and by angiography using the paired t-test (t=0.032, p=0.064) and there was a tendency towards underestimation between the length of the aortic end of the duct between 3D data and measurements by angiography using the paired t-test (r=0.140; p=0.281). There was adequate agreement between both 2D and 3D echocardiogram and angiography in determining the anatomical type of the patent ductus arteriosus (PDA).
Conclusion: Based on this small number of patients that were included, there was agreement between the location, size and morphology of PDA between 2D and 3D echocardiogram and angiography. This echocardiographic data will help in the selection of suitable device for duct occlusion.
