The efficacy and safety of patent ductus arteriosus stent versus surgical aortopulmonary shunt in the management of babies with duct dependent circulation: a meta-analysis and review of literature

Abstract

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.
