Surgical repair of acute Type A aortic dissection (AADA) has high mortality. Key risk factors for early death include longer perfusion times and postoperative stroke, highlighting the need for improved AADA surgical outcomes.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Background:
- Acute Type A aortic dissection (AADA) repair carries significant in-hospital mortality.
- Optimizing perioperative management is crucial for improving patient survival.
Purpose of the Study:
- To evaluate the impact of perioperative risk factors on early and midterm survival after AADA surgical repair.
- To identify significant predictors of mortality in AADA patients.
Main Methods:
- Retrospective analysis of 132 consecutive AADA patients (2002-2011).
- Surgical repair involved open distal anastomoses and hypothermic circulatory arrest.
- Procedures included aortic valve replacement/root replacement or valve re-suspension/repair.
Main Results:
- Overall in-hospital mortality was 17.4%.
- Actuarial survival at 8 years was 62%.
- Perfusion time, aortic cross-clamp time, aortic arch tear, instability, postoperative stroke, and low cardiac output correlated with increased perioperative mortality. Cox model identified perfusion time, postoperative stroke, age, and instability as significant risk factors.
Conclusions:
- Despite a trend towards improved outcomes, early mortality and morbidity after AADA surgical repair remain high.
- Further strategies are needed to mitigate perioperative risks and enhance survival in AADA patients.
