Background: The aim of this study was to determine if there is any correlation between patent ductus arteriosus (PDA) dimensions measured by two dimensional echocardiography (2DE) and three dimensional echocardiography (3DE) in comparison with angiographic data as the gold standard technique. Such correlation may help us to immediately detect ductal spasm and select the proper device according to echocardiographic assessments. Methods: In this comparative study, we successively selected 26 pediatric patients with isolated PDA, who referred for elective percutaneous PDA closure at Nemazee Hospital, affiliated to Shiraz University of Medical Sciences (SUMS) since January 2016 till March 2017. All patients underwent full 2DE and 3DE before device closure at the day of angiography (less than 5 hours before catheterization). We emphasized the dimension of pulmonic and aortic end diameter and length of PDA by these modalities and comparison of our data. Results: The study population had a mean age of 28.7 months and a mean weight of 10.67 Kg; the majority of our patients were female (84.6%). The difference in pulmonic end of PDA was not significant statistically by all modalities. The difference in aortic end of PDA was significant and there was no correlation between 2DE and 3DE with angiographic data. Comparison of data obtained from 2DE and 3DE revealed that the length of PDA in 2DE, 3DE angiography well correlated with each other. One case developed ductal spasm during angiography. Conclusions: The ductus pulmonic end and length dimensions measured by echocardiography and angiography well correlated with each other and were interchangeable. Such findings may be helpful during percutaneous transcatheter occlusion if any ductal spasm happens. Thus, we may recommend the use of a suitable device according to the maximum size of PDA that was measured either by echocardiography or angiographic studies.

Is There Any Correlation Between Two and Three Dimensional Echocardiography in Ductal Dimensions with Angiography?
