[MSB-14] Validation of the German Registry for Acute Aortic Dissection Type A Score After Aortic Dissection Surgery

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Aortic Disease Research

Background:

• Acute aortic dissection type A (ATAAD) is a life-threatening condition requiring prompt surgical intervention.
• Accurate prediction of operative mortality is crucial for patient management and resource allocation in ATAAD.
• Existing risk scores may not fully capture the complexity of ATAAD outcomes.

Purpose of the Study:

• To evaluate the predictive performance of the German Registry of Acute Aortic Dissection Type A (GERAADA) score for operative mortality in ATAAD patients.
• To assess the accuracy and clinical utility of the GERAADA score in a real-world cohort.

Main Methods:

• Retrospective analysis of 86 consecutive patients undergoing surgical repair for ATAAD.
• Data collection included 11 preoperative parameters for GERAADA score calculation.
• Comparison of GERAADA score predictions with actual 30-day mortality rates.

Main Results:

• The GERAADA score predicted a 30-day mortality of 22.94%, while the actual cohort mortality was 32.55%.
• The score demonstrated strong discriminative power with an area under the curve of 0.867.
• Key preoperative parameters contributing to the score were analyzed.

Conclusions:

• The GERAADA score provides an accurate prediction of 30-day mortality following surgical repair for ATAAD.
• Its accessibility via a web-based platform and reliance on basic clinical parameters enhance its clinical applicability.
• The score aids in risk stratification and informed decision-making for ATAAD management.
