Key result
Minimal- and zero-fluoroscopy transcatheter PDA closure reduces radiation without compromising safety versus conventional techniques.
Why the study?
Recent advances in imaging, device technology, and procedural planning have transformed transcatheter PDA closure, necessitating an outline of the evolution from conventional fluoroscopy to contemporary radiation-sparing strategies.
Does transcatheter PDA closure using radiation-sparing protocols improve safety and reduce radiation exposure compared to conventional fluoroscopy in patients with PDA?
Does transcatheter PDA closure using radiation-sparing protocols improve safety and reduce radiation exposure compared to conventional fluoroscopy in patients with PDA?
Transitioning from classical fluoroscopy to echocardiography-guided and radiation-sparing protocols for transcatheter PDA closure reduces radiation exposure while maintaining safety.
May support radiation-sparing PDA closure in select patients; leaves open need for randomized trials before practice change.
Patent ductus arteriosus (PDA) is a common congenital cardiac defect traditionally managed by surgical and transcatheter closure under fluoroscopic guidance. Over recent years, significant advances in imaging modalities, device technology, and procedural planning have transformed the pathway for PDA closure, reducing reliance on classical fluoroscopy-based techniques. This review outlines the evolution of transcatheter PDA closure from conventional fluoroscopic approaches to contemporary strategies incorporating echocardiographic guidance, hybrid imaging, and radiation-sparing protocols. These changes have enhanced procedural safety, reduced radiation exposure to patients and operators, shortened procedure times, and expanded eligibility to younger and higher-risk populations. Understanding this evolving pathway is essential for optimizing outcomes and guiding future practice in transcatheter PDA closure.

Siagian et al. (2026) conducted a review in Patent ductus arteriosus (PDA). Minimal-fluoroscopy and zero-fluoroscopy transcatheter closure vs. Classical fluoroscopy-guided closure was evaluated. Minimal-fluoroscopy and zero-fluoroscopy approaches for transcatheter patent ductus arteriosus closure reduce radiation exposure while maintaining procedural safety compared to classical techniques.
