A groundbreaking consensus statement has been released by the Society for Cardiovascular Angiography & Interventions (SCAI), offering meticulous guidance for the transcatheter closure of patent ductus arteriosus (PDA) in premature infants. This significant publication outlines a robust framework encompassing patient selection, refined procedural techniques, essential training benchmarks for medical professionals, and the critical institutional support necessary for optimal outcomes. It underscores a paradigm shift in the management of this common cardiac condition in neonates, moving towards a standardized, team-centric approach to minimize complications and foster long-term health for these delicate patients.

Enhancing Care: A Detailed Look at PDA Closure for Fragile Neonates

On August 18, 2025, the Society for Cardiovascular Angiography & Interventions (SCAI) unveiled its pivotal position statement in the esteemed Journal of the Society for Cardiovascular Angiography & Interventions (JSCAI). This landmark document, titled \"SCAI Position Statement on Transcatheter Occlusion of Patent Ductus Arteriosus in Premature Infants,\" provides comprehensive, evidence-based guidance for the transcatheter occlusion of patent ductus arteriosus (tcPDA) in premature infants.

The statement is meticulously structured around four foundational pillars:

1. Patient Selection Precision: Emphasizing a collaborative decision-making process involving neonatologists, cardiologists, and families, the guidelines detail specific criteria for patient selection. This includes an assessment of respiratory status, echocardiographic findings, and indicators of systemic perfusion, ensuring that only the most suitable candidates undergo the procedure.
2. Technical Mastery and Procedural Excellence: For fragile premature neonates, the statement delineates best practices for the technical aspects of the procedure. This covers everything from appropriate device selection and advanced imaging techniques to optimal anesthesia protocols and crucial strategies for complication prevention.
3. Rigorous Operator Training: To uphold the highest standards of care, the SCAI has proposed clear benchmarks for operator training. These include specific case volume recommendations for both interventional cardiology trainees and experienced practitioners, aimed at ensuring adequate proficiency and expertise.
4. Robust Institutional Infrastructure: Recognizing the specialized needs of this patient population, the guidelines highlight the necessity for comprehensive institutional infrastructure. This encompasses neonatal-specific ventilation and thermoregulation equipment, state-of-the-art imaging capabilities, and readily available pediatric cardiac surgical backup.

Dr. Brent M. Gordon, FSCAI, a distinguished Professor of Pediatrics at Rady Children's Hospital in San Diego, California, and the esteemed chair of the writing committee, articulated the profound significance of this collaborative endeavor. He highlighted that while pharmacological interventions successfully close PDA in approximately two-thirds of premature infants, a significant proportion, along with those necessitating urgent closure, still require procedural intervention. The overarching objective, as Dr. Gordon underscored, is to empower medical teams to execute these procedures with utmost safety and efficacy, thereby granting these vulnerable infants the most auspicious beginning to life.

Transcatheter PDA closure has long been a cornerstone of congenital interventional cardiology. However, extremely low birth weight infants were historically excluded due to inherent access challenges and the absence of appropriately sized devices. This began to change dramatically in 2019, when the U.S. Food and Drug Administration (FDA) approved the first PDA occlusion device specifically designed for infants weighing as little as 700 grams. This approval catalyzed a swift and widespread adoption of tcPDA in premature infants, with catheter-based closure rapidly eclipsing traditional surgical ligation in numerous medical centers, yielding promising early results. The position statement firmly asserts that sustained long-term success is now contingent upon the consistent and high-quality implementation of these procedure-specific best practices.

The document meticulously reviews patient selection criteria and pre-procedural planning, crucial steps for optimizing patient readiness for tcPDA. It also candidly addresses potential complications, including tricuspid valve injury, cardiac perforation, and late-onset vessel obstruction. To mitigate these risks, the authors strongly advocate for preventative measures through meticulous planning, prompt recognition of issues during and after the procedure, and swift intervention when necessary. They recommend a structured echocardiographic follow-up regimen at 24 hours, one week, one month, three months, and six months post-procedure to facilitate early detection and management of any complications before they adversely affect patient outcomes.

Furthermore, the statement meticulously outlines suggested operator training benchmarks, ensuring that physicians performing tcPDA possess the requisite experience to safely and effectively prepare for and execute the procedure. Acknowledging the imperative for specialized care, the document emphasizes the importance of robust regional referral networks and streamlined transport protocols. These measures are designed to ensure that infants receive treatment at facilities equipped with the necessary expertise and resources.

Dr. Sarosh \"Shawn\" P. Batlivala, FSCAI, a Professor at the UC Department of Pediatrics, Cincinnati Children's Hospital Medical Center, and co-chair of the writing committee, eloquently articulated that technological advancements have revolutionized the treatment of premature infants with PDA. However, he emphasized that technology alone is insufficient. These intricate procedures demand scrupulous planning, an profound comprehension of neonatal physiology, and seamless coordination among every member of the care team. Dr. Batlivala’s remarks highlighted that the recommendations extend beyond merely performing the intervention, encompassing patient preparation, anticipating potential challenges, and providing comprehensive follow-up to ensure that initial successes translate into enduring healthy long-term outcomes.

Looking ahead, the writing group passionately called for continuous quality improvement initiatives and expanded research efforts. These endeavors aim to refine patient selection processes, optimize procedural techniques, and inform the design of future devices. The authors strongly encouraged medical institutions to contribute to national registries and diligently maintain local databases. This collective effort will significantly strengthen the evidence base, ultimately enhancing survival rates and improving the quality of life for premature infants across the globe.

This comprehensive position statement marks a pivotal moment in pediatric cardiology, setting a new standard for the care of premature infants with PDA. Its emphasis on collaboration, meticulous planning, and ongoing improvement promises a brighter future for these vulnerable lives.
