Clinical Report: Comparative Analysis of Autologous Patches in Aortic Arch Reconstruction

Overview

This study compares clinical and morphological outcomes of autologous pericardial patches (PP) and pulmonary artery patches (PAP) in infants undergoing aortic arch reconstruction. Both patch types showed comparable early mortality and long-term recoarctation rates, although PAP resulted in larger initial arch diameters.

Background

Aortic arch reconstruction in neonates and infants is critical for managing congenital heart defects such as coarctation and interrupted aortic arch. The choice of patch material can influence surgical outcomes, including growth and recoarctation rates. Understanding the comparative effectiveness of PP and PAP is essential for optimizing surgical strategies in this vulnerable population.

Data Highlights

Key Findings

• Cardiopulmonary bypass and cross-clamp times were significantly longer with PAP (P < 0.001).
• Early mortality rates were comparable between PP and PAP groups (4.2%; P = 0.698).
• 10-year freedom from recoarctation was similar for both patch types (88.4%; P = 0.958).
• Pre-discharge systolic peak velocity >2.48 m/s was a significant predictor of recoarctation (HR, 7.373; P < 0.001).
• PAP resulted in a larger initial proximal arch-to-ascending aorta diameter ratio (P < 0.001).
• Longitudinal growth trajectories were similar for both patch types despite initial differences.

Clinical Implications

Surgeons should consider both PP and PAP as viable options for aortic arch reconstruction in infants, as both provide comparable outcomes. Monitoring pre-discharge systolic peak velocity may help identify patients at risk for recoarctation, guiding postoperative management.

Conclusion

Both autologous pericardial and pulmonary artery patches yield similar clinical and morphological outcomes in aortic arch reconstruction. The choice of patch should prioritize achieving optimal initial geometry to minimize the risk of late recoarctation.
