Genesis stent implantation without using a long sheath in two children

Area of Science:

• Cardiology
• Pediatric Interventional Cardiology
• Biomedical Engineering

Background:

• Congenital heart defects can lead to vascular stenosis, requiring interventions in pediatric patients.
• Superior vena cava (SVC) stenosis and pulmonary artery branch stenosis are critical conditions affecting blood circulation.
• Previous interventions for these conditions may have limitations in pediatric cases.

Observation:

• A Genesis stent was implanted in two children with distinct forms of vascular stenosis.
• Case 1 involved a 2-month-old infant with SVC stenosis post-total anomalous pulmonary venous connection (TAPVC) repair.
• Case 2 involved a 2-year-old child with left lower pulmonary artery stenosis following complex congenital heart defect repair.

Findings:

• Both Genesis stent implantations resulted in immediate clinical and hemodynamic improvements.
• The stent's closed-cell design with sigma hinges facilitated its deliverability and expandability.
• Successful deployment was achieved through smaller sheaths, indicating suitability for pediatric vasculature.

Implications:

• The Genesis stent demonstrates potential as an effective treatment for pediatric vascular stenosis.
• Its improved characteristics may enhance procedural success rates and reduce complications in infants and children.
• This technology could expand treatment options for complex congenital heart disease patients requiring vascular interventions.
