To report the use of a fenestrated PECA exGraft as an internal pulmonary artery band in a male infant diagnosed with complex congenital heart disease.
Approach:
Case Presentation: A male infant with heterotaxy syndrome and multiple cardiac anomalies was treated with transcatheter pulmonary flow restriction due to severe pulmonary overcirculation and later underwent surgical implantation of a fenestrated PECA exGraft.
Key Findings:
Transcatheter pulmonary flow restrictors stabilized the patient before surgical intervention.
The PECA exGraft allowed for controlled and predictable expansion, maintaining structural integrity.
Balloon dilation of the PECA exGraft resulted in consistent mechanical behavior and effective management of pulmonary blood flow.
Interpretation:
The use of the PECA exGraft as an internal pulmonary artery band represents a novel surgical approach for managing pulmonary blood flow in neonates with complex congenital heart disease.
Limitations:
The long-term outcomes of using the PECA exGraft in this context remain to be fully evaluated, and the findings are based on a single patient experience.
Conclusion:
The fenestrated PECA exGraft serves as a customizable solution for internal pulmonary artery banding in neonates, allowing for adjustments as the patient grows.
An ensemble electrocardiogram model classified derived diastolic dysfunction risk phenotypes and stratified heart failure–related death risk across external cohorts, according to findings presented at ASE 2026.
