Delay from Diagnosis to Surgery in Transferred Type A Aortic Dissection

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Disease

Background:

• Type A acute aortic dissection is a life-threatening condition requiring prompt surgical intervention.
• Delays in surgical management can negatively impact patient outcomes.
• Understanding factors contributing to these delays is crucial for improving patient care.

Purpose of the Study:

• To analyze factors associated with delays to surgical management in patients with Type A acute aortic dissection.
• To identify specific clinical characteristics and diagnostic pathways that influence treatment timelines.

Main Methods:

• Retrospective analysis of 1880 surgically managed Type A acute aortic dissection patients from the International Registry of Acute Aortic Dissection.
• Evaluation of time from diagnosis to surgery and associated clinical factors.
• Comparison of treatment delays between transferred and non-transferred patients.

Main Results:

• Transferred patients experienced significantly longer median delays (4.0 hours) compared to non-transferred patients (2.3 hours).
• Emergent symptoms (cardiac tamponade, hypotension, shock) expedited treatment in both groups.
• Factors such as MRI use and prior cardiac surgery were associated with longer delays, while certain pain characteristics and severe complications in transferred patients led to quicker treatment.

Conclusions:

• Patient transfer is a significant factor contributing to surgical delays in Type A acute aortic dissection.
• Clinical presentation, diagnostic workup, and patient history influence the extent of treatment delays.
• While delays were observed, overall mortality did not differ significantly between transferred and non-transferred patients.
