“…Transthoracic echocardiography was performed according to the guidelines (8,9) to diagnose the disease, determine the size and confluency of the pulmonary arteries, and evaluate the anatomy of the PDA. Before the procedure, a CT scan was performed if the anatomy of the PDA course and pulmonary arteries was unclear.…”

Background: Patent ductus arteriosus (PDA) stenting was invented particularly for congenital heart diseases with ductal-dependent pulmonary blood flow, and newer techniques are constantly being introduced. Objectives: In this study, we investigate the one-year results of this procedure and describe some of our periprocedural considerations. Methods: The neonates with pulmonary atresia and ventricular septal defect (VSD) who underwent PDA stenting in our center from February 2016 to December 2019 were included in this retrospective study. Spo2 and McGoon ratios were recorded before and a year after stenting and compared to each other. Results: In 26 neonates, PDA stenting was performed; 20 procedures (77%) were successful, and six procedures (23%) were unsuccessful. Two of these unsuccessful cases died during the procedure, and two of them died as a result of neonatal sepsis following the procedure. A total of 18 PDAs (70%) were accessed via the axillary artery, 6 (23%) via the femoral artery, and 2 (7%) via the antegrade inferior vena cava route. The comparison between the results before and one year after stenting revealed the increase of O2 saturation from 53.78 ± 7.35 to 84.33 ± 6.5 (P-value = 0.032) and McGoon ratio from 1.16 ± 0.25 to 1.65 ± 0.34 (P-value = 0.041). Additionally, we discussed some technical considerations of PDA stenting, including the access point, management of pulmonary artery bifurcation stenosis, stent diameter, stenting of long and tortuous PDAs, thrombosis, and anticoagulation. Conclusions: Ductal stenting increases SpO2 and McGoon ratio and could be a less-invasive option for securing pulmonary blood circulation. However, further studies are required to advance PDA stenting techniques for specific anatomical features.

Background Closure of perimembranous ventricular septal defects (pmVSD), either surgical or percutaneous, might improve or cause new-onset mitral regurgitation (MR) and aortic regurgitation (AR). We aimed to evaluate the changes in MR and AR after pmVSD closure by these two methods. Material and method We performed a comparative retrospective data review of all pediatric patients with pmVSDs treated at our institution with surgical or antegrade percutaneous methods from 2014 to 2019 and 146 consecutive patients under 18 years were enrolled. We closely looked at the mitral and aortic valve function after repair. Included patients had no or lower than moderate aortic valve prolapse and baseline normal mitral or aortic valve function or less than moderate MR or AR. Results Out of 146 patients, 83 (57%) pmVSDs were closed percutaneously, and 63 (43%) pmVSDs were closed surgically. 80 and 62 patients were included for MR evaluation, and 81 and 62 patients for AR evaluation in percutaneous and surgical groups. The mean follow-up time was 40.48 ± 21.59 months in the surgery group and 20.44 ± 18.66 months in the transcatheter group. Mild to moderate degrees of MR and AR did not change or decreased in most patients. In detail, MR of 70% and AR of 50% of the valves were resolved or decreased in both groups. 13% of patients with no MR developed trivial to mild MR, and 10% of patients with no AR showed mild to moderate AR after pmVSD closure in both methods. There was no significant difference between the two methods regarding emerging new regurgitation or change in the severity of the previous regurgitation. Conclusion pmVSD closure usually improves mild to moderate MR and AR to a nearly similar extent in both percutaneous and surgical methods among children and adolescents. It might lead to the onset of new MR or AR in cases with no regurgitation.
