Comparison of Patch Materials for Pulmonary Artery Reconstruction

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiac Surgery
• Biomaterials in Medicine

Background:

• Pulmonary artery reconstruction often involves various patch materials with differing costs.
• Informing value-based decisions requires understanding the relationship between patch material and reintervention rates.

Purpose of the Study:

• To analyze reintervention rates based on different patch materials used in pulmonary artery reconstruction.
• To evaluate if patch material type influences the need for subsequent interventions.

Main Methods:

• Retrospective review of 214 pulmonary artery reconstruction sites (2000-2014) at a single center.
• Exclusion of patients with unifocalization of aortopulmonary collaterals.
• Analysis of reintervention as the primary outcome, utilizing Cox proportional hazards regression.

Main Results:

• No significant relationship was found between the type of patch material (homograft, bovine pericardium, autologous pericardium, porcine submucosa) and reintervention rates (P=0.197).
• Preoperative renal failure (HR 4.36) and lower weight at surgery (HR 0.93) were associated with increased reintervention.
• Patch costs varied widely, from $0 for autologous pericardium to $6,105 for homograft branch patch.

Conclusions:

• Patch material type is not a determinant of reintervention for pulmonary artery reconstruction.
• Disparities in patch material costs, without impact on reintervention, can guide value-based healthcare decisions.
• Surgeons can prioritize cost-effectiveness without compromising clinical outcomes related to reintervention.
