German Registry for Acute Aortic Dissection Type A: Structure, Results, and Future Perspectives

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Dissection Research

Background:

• The German Registry for Acute Aortic Dissection Type A (GERAADA) is a large international registry.
• It collects data from 56 centers across Germany, Austria, and Switzerland.
• GERAADA aims to address questions not answerable by single-institution databases.

Purpose of the Study:

• To analyze outcomes and risk factors in surgically treated acute aortic dissection type A (AADA) patients.
• To evaluate the impact of different surgical techniques and patient demographics on mortality and neurologic dysfunction.
• To establish GERAADA as the largest global AADA database for future research.

Main Methods:

• Analysis of the second validated GERAADA dataset (2006-2010) including 2,137 surgically treated AADA patients.
• Identification of risk factors for postoperative neurologic dysfunction.
• Comparison of mortality rates across different age groups and surgical strategies.

Main Results:

• Overall 30-day mortality was 16.9%, with new postoperative neurologic dysfunction in 9.5% of patients.
• Malperfusion syndromes, supra-aortic vessel dissections, and longer operating times were risk factors for neurologic dysfunction.
• Octogenarians had a significantly higher mortality rate (34.9%) compared to septuagenarians (15.8%) and the overall cohort.
• Antegrade selective cerebral perfusion (ACP) is advisable for longer arrest periods (>30 minutes).

Conclusions:

• GERAADA provides the largest validated dataset on AADA worldwide.
• Risk stratification and tailored surgical approaches are crucial for improving AADA outcomes.
• Long-term follow-up data from GERAADA will further enhance understanding of AADA management.
