Transcatheter pulmonary flow restrictors in a 2.4 kg neonate with complex truncus arteriosus as long-term bridge to primary infant heart transplant

In recent years, the use of modified Micro Vascular Plugs (MVP) (Medtronic, Galway, Ireland) as branch pulmonary artery flow restrictors has been reported in different congenital cardiac pathologies with single ventricle physiology as part of a transcatheter stage I procedure.

To our knowledge, we report for the first time successful transcatheter implantation of modified Micro Vascular Plugs as pulmonary flow restrictors in a small-for-gestational-age neonate with truncus arteriosus and a hypoplastic right ventricle to create stable physiology and facilitate eligibility for a heart transplant.
