RESUMEN
OBJECTIVES: We intend to describe an entirely transcatheter management pathway for patients with pulmonary atresia with intact ventricular septum (PA/IVS). BACKGROUND: PA/IVS is a rare cyanotic congenital heart lesion traditionally palliated with multiple procedures and surgeries. Entirely non-surgical transcatheter management from infancy to adulthood may be possible; however, the pathway from neonatal radiofrequency (RF) pulmonary valve perforation to later transcatheter pulmonary valve replacement (TPV) is not well described. METHODS: This retrospective study was performed at a pediatric cardiac center between 2007-2018. All patients with PA/IVS who were managed exclusively with catheterization-based interventions as neonates (RF perforation, pulmonary valvuloplasty, or ductal stenting) were analyzed. Demographic, procedural and clinical data were collected. RESULTS: Fifteen patients had exclusively catheterization-based RV decompression as neonates, 7 of whom did not require subsequent surgery. Six patients required a right ventricular outflow tract (RVOT) augmentation later in life; all were born before 2013. All 6 later had a TPV placed. Two of the patients underwent a surgical Glenn shunt alone. Of the 7 patients that never had surgery, 3 have since undergone a TPV, and 4 are awaiting candidacy for TPV placement. No patients with PA/IVS have had an RVOT augmentation at our institution since 2012. CONCLUSIONS: Patients with PA/IVS who undergo catheterization-based neonatal interventions can make it to TPV without requiring surgery. At our institution, there has been a shift in management over the last 8 years favoring entirely non-surgical transcatheter management from infancy to adulthood.
