Advances in Pediatric Ductal Intervention: an Open or Shut Case?

PURPOSE OF REVIEW

To review the most recent literature on pediatric transcatheter ductal intervention including ductus arteriosus occlusion and stenting.

RECENT FINDINGS

With the development and FDA approval of smaller ductal devices, including most recently the Amplatzer Piccolo Occluder (Abbott, Abbott Park, IL), transcatheter ductus arteriosus device closure is now being safely performed in premature infants and patients < 6 kg using a transvenous approach. In patients with ductus-dependent pulmonary blood flow, ductal stenting with pre-mounted coronary artery stents has been shown to be an acceptable alternative to the surgically placed Blalock-Taussig shunt. Centers with experience in ductal stenting have demonstrated success, even with the tortuous ductus. Innovation in transcatheter device technology and procedural practices have allowed for significant advances. Transcatheter ductal device closure is a reasonable alternative to surgical ligation even in premature, low-birthweight infants. Ductal stenting is also an accepted alternative to the modified Blalock-Taussig shunt. We anticipate continued advancement and procedural refinement over the next several years.
