Valve-Sparing Aortic Root Replacement in Pediatric Patients: Lessons Learned Over Two Decades

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Aortic Aneurysm Research

Background:

• Valve-sparing aortic root replacement (VSARR) offers an alternative to traditional prostheses for pediatric proximal aortic aneurysms.
• Connective tissue disorders are common in pediatric patients with aortic root aneurysms, but other conditions are increasingly recognized.
• Congenital heart disease and non-syndromic thoracic aortic aneurysms represent emerging diagnostic groups for VSARR.

Purpose of the Study:

• To present the authors' experience with valve-sparing procedures in pediatric patients.
• To highlight the technical nuances of performing VSARR in children.
• To discuss the encountered pitfalls and complications of pediatric VSARR.

Main Methods:

• Retrospective review of pediatric patients undergoing valve-sparing aortic root replacement over a 20-year period.
• Detailed analysis of surgical techniques and procedural steps.
• Documentation and categorization of all complications and adverse events.

Main Results:

• Valve-sparing aortic root replacement has been successfully applied in diverse pediatric populations.
• Specific technical challenges and solutions for pediatric VSARR were identified.
• A spectrum of complications, including reoperations and long-term sequelae, were observed.

Conclusions:

• VSARR is a valuable technique for pediatric aortic root aneurysms across various etiologies.
• Careful surgical technique and awareness of potential complications are crucial for optimal outcomes.
• Long-term follow-up is essential to manage potential late complications in pediatric patients undergoing VSARR.
