RESUMO
INTRODUCTION: Cardiac perforation is a rare life-threatening complication of cardiac catheterization. There is very little published literature detailing risk factors for cardiac perforation and outcomes from this complication in children. MATERIALS AND METHODS: This was a retrospective study analyzing the cardiac catheterization case registry of the Congenital Cardiovascular Interventional Study Consortium. Children aged < 18 years were included during the study period of 9 years (January 2009-December 2017). The primary outcome measures were incidence of cardiac perforation, risk factors for and outcomes of patients who experience cardiac perforation during cardiac catheterization. RESULTS: Cardiac perforation occurred in 50 patients from a total of 36,986 (0.14%). Cardiac perforation was more likely to occur in younger, smaller patients undergoing urgent/emergent and interventional procedures (p < 0.01). Cardiac peroration risk was significantly different across diagnostic and procedure categories (p < 0.01). Higher CRISP score (Area Under Curve [AUC] = 0.87), lower age, and procedure category (radiofrequency perforation of pulmonary valve, AUC = 0.84) were independent predictors of cardiac perforation. Cardiac perforation was associated with a significantly higher rate of mortality (14%), further emergency procedure (42%), ECMO (14%), and cardiac arrest (6%), p < 0.01. CONCLUSIONS: Cardiac perforation during cardiac catheterization is a life-threatening complication with a range of associated secondary complications. Higher CRISP score, lower age, and radiofrequency perforation of pulmonary valve are independent predictors.

Modest secundum atrial septal defects (2°ASD) may cause significant pulmonary over perfusion during infancy, particularly in conjunction with left heart obstructive lesions. Amplatzer Septal Occluders are not ideal in this setting especially given recent concerns regarding device erosion. We report the first use of the Amplatzer Duct Occluder II device (ADO2) to close a 2°ASD in a 4.5 kg infant.

The aim of catheter intervention for vascular stenosis is the restoration of lumen area and optimization of distal blood flow. In pediatric practice, this has traditionally been a compromise between less effective balloon angioplasty and bare metal stent insertion with its attendant limitations of size. Bioabsorbable stents offer short-term relief of stenosis, radial support of the healing lesion, return of endothelial function and crucially, in children, the potential for long-term growth. Initial experience, in pediatric practice, with metal-based bioabsorbable stents was relatively disappointing with frequent restenosis secondary to early reabsorption. Design modifications resulting in polymer-based, drug eluting, bioabsorbable vascular scaffolds (BVS) have reportedly overcome some of these faults. We describe the first reported use of a drug eluting BVS in three patients with: (1) A newborn with severe right pulmonary artery (RPA) stensosis post repair of type two common arterial trunk. (2) A child with pulmonary atresia/ventricular septal defect (VSD) and major aorto-pulmonary collateral arteries (MAPCAs), and (3) An infant with severe left pulmonary artery (LPA) stenosis in the setting of an LPA sling.

OBJECTIVES: To evaluate Fontan fenestration closure using the Amplatzer Duct Occluder II device (ADO2). BACKGROUND: Fontan fenestration closure is a well established catheter intervention. A range of occlusion devices developed for other interventions have been utilized. Most of these devices, and especially the most commonly used Amplatzer Septal Occluder, are relatively bulky. The ADO2 is a low profile, flexible, and inexpensive device which seems well suited to the Fontan fenestration. METHODS: This study details retrospective review of patients undergoing Fontan fenestration closure with an ADO2 device. Outcome measures included procedural success, pre- and post-procedural differences in oxygen saturation and mean pulmonary artery pressure and complications. RESULTS: Thirteen patients were eligible for inclusion during the 34 month study period. All procedures were technically successful. There was a significant increase in oxygen saturations (Mean=+12%, P<0.01) after fenestration closure but no significant change in mean pulmonary artery pressure (Mean=+0.5 mm Hg, P=0.08). There were no procedural complications. CONCLUSION: Fontan fenestration closure with the ADO2 device is a simple, short, and cost-effective procedure. The ADO2 characteristics recommend it to occlusion of varying sizes and morphologies of Fontan fenestration.
