Aortic dissection repair with GRF glue complicated by heart block

Area of Science:

• Cardiovascular Surgery
• Biomaterials Science
• Pathophysiology

Background:

• Acute ascending aortic dissection is a life-threatening condition requiring prompt surgical intervention.
• Gelatin-resorcin-formaldehyde-glutaraldehyde (GRF) biologic glue is utilized as an adjunct in the operative repair of aortic dissections.
• Understanding potential complications associated with novel surgical adjuncts is crucial for patient safety.

Observation:

• Two out of six patients undergoing operative repair for acute ascending aortic dissection experienced permanent complete heart block.
• The complication of heart block occurred post-operatively following the application of GRF biologic glue.
• The incidence of heart block suggests a potential link to the surgical intervention or the GRF glue itself.

Findings:

• Permanent complete heart block is a significant complication observed in a subset of patients undergoing aortic dissection repair with GRF glue.
• The exact cause of heart block in these cases remains unclear, necessitating further investigation.
• Both the underlying pathology of the dissection and the surgical technique involving GRF glue application are considered potential contributors.

Implications:

• The findings highlight a critical safety concern associated with the use of GRF biologic glue in aortic dissection repair.
• Further research is warranted to elucidate the pathophysiology of heart block in this context.
• This information may influence surgical decision-making and the development of safer adjuncts for aortic dissection repair.
