We report our experience with stenting of the ductus arteriosus in three neonates. Two patients had pulmonary atresia with an intact interventricular septum and one had critical pulmonary stenosis. Radiofrequency ablation was used to open the atretic pulmonary valve in two patients. In all three patients implanting a stent avoided the need for surgical creation of a Blalock-Taussig shunt. In two patients the procedure was scheduled as elective surgery, and in one it was done as an emergency procedure. Ductus arteriosus stenting is an alternative to palliative cardiac surgery.
Stent implantation in the ductus arteriosus for pulmonary blood supply in congenital heart disease
Catheterization and Cardiovascular Interventions, 2004
Indications for catheter-based interventions in patent ductus arteriosus (PDA)-dependent pulmonary blood flow have yet to be defined. The aim of this study was to assess the acute and midterm outcome after stent implantation in the PDA. Between 1996 and 2002, ductal stenting was performed in 21 neonates and infants (14 females/7 males) to maintain pulmonary blood supply in cyanotic congenital heart disease (CHD). Balloonexpandable stents were implanted in the PDA with a final diameter of 4 -5 mm without procedural deaths. Stent patency was achieved for 8 -1,130 days (median, 142). Reintervention was necessary in nine patients. Overall survival rate after 6 years was 86%. Two neonates died a few days after the procedure due to right heart failure not related to PDA stenting. Corrective surgery was possible in six patients. An additional aortopulmonary shunt was needed in three patients; Fontan type operations were performed in six. One patient died after bidirectional Glenn shunt, another five reached palliation by additional perforation of the atretic valve/balloon valvuloplasty, and two are awaiting surgery. We conclude that in many patients with cyanotic CHD, especially in those with ductal pulmonary perfusion and additional forward flow from the right ventricle, ductal stenting is an effective transcatheter approach. Morphology of the PDA predicts the risk of restenosis and necessity of reintervention. Growth of the pulmonary vascular bed allows corrective or palliative surgery, and some patients can be cured by the intervention alone.

This meta-analysis aims to comprehensively assess the efficacy and safety of both patent ductus arteriosus (PDA) stents and surgical aortopulmonary shunt (APS) as the initial palliative measures in babies relying on ductal-dependent circulation. This review is essential to compare the outcome of relatively newer catheter-based PDA stent procedure with a surgical APS. By synthesizing existing literature, this review aims to provide insights to inform clinical practice and enhance patient care in this challenging clinical scenario. The methodology involved an extensive search of PubMed and Embase databases using specific keywords and terminology related to mortality, procedural outcomes, and postprocedural complications following PDA stent and APS in cyanotic congenital heart defects (CHD) patients. Six retrospective observational studies met the criteria, with 757 patients included. The analysis showed comparable mortality rates between PDA stents and APS. However, PDA stents were associated with decreased risks of mechanical circulatory support, postprocedural complications, and shorter hospital stays, mechanical ventilation, and intensive care unit stays compared to APS. Notably, patients with pulmonary atresia scheduled for biventricular surgery were more prevalent among those receiving PDA stents. In conclusion, while the risk of mortality is similar between PDA stents and APS, PDA stents offer advantages such as shorter hospital stays and reduced complications. Patient characteristics also vary, with a higher prevalence of intact ventricular septum among those receiving PDA stents.

Introduction: Ducts-dependent pulmonary circulation is spectrum of congenital heart diseases that need urgent intervention to augment pulmonary blood. Systemic to pulmonary shunt is the classical surgical management. Stenting of ductus arteriosus emerged in the last 2 decades as an alternative plausible intervention. Objectives: To evaluate and compare the short and midterm effects of PDA stenting in compared to surgically placed shunt for augmentation of pulmonary blood flow looking to pulmonary artery (PA) branches growth, oxygen saturation and suitability for second stage repair. Methods: We conducted this prospective study in Cardiac Surgical Intensive Care Unit. Cases were divided into "stent group" and "surgical shunt" group. Results were compared between two groups regarding oxygen saturation, mechanical ventilation duration, intensive care stay, mortality and morbidity. Growth of PA branches was assessed during follow up by echocardiograph. Nakata index score was calculated by angiogram before second stage surgery and was compared between both groups. Results: 43 patients were included. Forty-two cases were offered stent as initial management. 6/42 cases failed stenting (14%) and 3/42 (7%) required late BT shunt after PDA stenting. 10/43 cases ended up receiving BT shunt and were counted as "surgical shunt group". Stent group (33 cases) needed less mechanical ventilation (2.08 ± 0.65 vs.7.8 ± 4 days with p ¼ 0.014), and less ICU stay compared with surgical shunt group (6.2 ± 1.02 vs. 14 ± 4.5 days, P ¼ 0.009). Both groups achieved similar growth of pulmonary artery branches (p ¼ 0.6 for Z score of left pulmonary artery and P ¼ 0.8 for Z score for right pulmonary artery). Although "stent group" reached second stage surgery with lower O2 saturation 67.6 ± 4.6 vs. 80 ± 4.2 in "surgical shunt" group with P value ¼ 0.0002). Majority of patients in both groups had some PA distortion and needed surgical reconstruction in main pulmonary artery or in its main branches during second stage repair. 3 cases (7.1%) died soon post stenting versus none in surgical shunt group (p value ¼ 0.57). Conclusions: In neonates with ductus-dependent pulmonary circulation PDA stenting can be introduced as safe first possible option to augment pulmonary blood flow with good outcome and suitable preparation for second stage palliation.

Background: Right ventricular outflow tract (RVOT) stents have been used as palliation in patients with severe tetralogy of Fallot (TOF). Radiofrequency perforation of the RVOT has also been described in patients with pulmonary atresia (PA)/ventricular septal defect (VSD). However, RVOT stenting in conjunction with radiofrequency perforation as a means for establishing reliable pulmonary blood flow in patients with PA/VSD has not previously been reported. Objectives: Our aim is to report our experience with using perforation of plate-like pulmonary valve atresia combined with stenting of RVOT as an alternative and equally efficacious intervention for infants with PA/VSD, as compared to a surgical pulmonary artery shunt (SPS). Methods: A retrospective review of patients with PA/VSD at our institution from Jan 2006 to October 2015 was performed. Results: Twenty-seven patients received palliation for PA/VSD. Five (median 2.5 kg, 2.1-4.1 kg) underwent RVOT stenting and 22 (3.5 kg, 2.1-4.6 kg) underwent surgical SPS. Of the patients who received an RVOT stent, 3 underwent guidewire perforation and balloon dilation of the plate-like pulmonary valve, and 2 underwent radiofrequency perforation of the pulmonary plate, followed by balloon dilation. Postprocedure saturations averaged 93% in the stent group and 89% in the shunt group. One of the patients who underwent RVOT stenting required additional stenting of the PDA for isolation of the LPA, but none required re-intervention. Four patients in the SPS cohort required re-intervention (18%). Two required stenting of the shunt, and 2 required surgical revision of the shunt. There was one death in the stent group, however this was secondary to withdrawal of support given an underlying genetic diagnosis (trisomy 13). There was one fatality in the SPS cohort prior to hospital discharge. Conclusions: Perforation followed by RVOT stenting may be a safe and effective alternative to surgical SPS in infants with PA/VSD.
Transcatheter stenting of arterial duct in duct-dependent congenital heart disease

Introduction. Critical congenital heart diseases (CHD) are mostly duct-dependent and require stable systemic-pulmonary communication. In order to maintain patency of the ductus arteriosus (DA), the first line treatment is Prostaglandin E1 and the second step is the surgical creation of aortic-pulmonary shunt. To reduce surgical risk in neonates with the critical CHD, transcatheter stenting of DA can be performed in selected cases. Case Outline. A four-month old infant was diagnosed with the pulmonary artery atresia with ventricular septal defect (PAA/VSD). The left pulmonary artery was perfused from DA, and the right lung through three major aortopulmonary collaterals (MAPCAs). A coronary stent was placed in the long and critically stenotic DA, with final arterial duct diameter of 3.5 mm, and significantly increased blood supply to the left lung. After the procedure, the infant?s status was improved with regard to arterial oxygen saturation, feeding and weight gain. During the follo...
