Unpredictable Aortic Behavior in Identifying Risk Factors for Reintervention: A Prospective Cohort Study

Area of Science:

• Cardiovascular Surgery
• Thoracic Aortic Disease Management
• Aortic Repair Outcomes

Background:

• Thoracic aortic disease management has improved acute mortality.
• Postoperative reintervention significantly worsens long-term outcomes and survival.
• Identifying risk factors for reintervention is crucial for this high-risk population.

Purpose of the Study:

• To identify risk factors for postoperative reintervention in patients with thoracic aortic disease.
• To analyze predictors of reintervention after primary open or endovascular repair.

Main Methods:

• Prospective observational cohort study (January 2009 - June 2020).
• Included patients surviving initial endovascular or open surgical repair for thoracic aortic disease.
• Multivariate logistic regression and Cox proportional hazards models used to identify risk factors.

Main Results:

• 95 genetically tested patients (mean age 54.13 years; 67% men) included.
• 35.8% required reintervention at a mean follow-up of 3 years.
• Postoperative residual aortic dissection was the sole independent predictor of reintervention (OR: 3.29).

Conclusions:

• Reintervention after primary thoracic aortic repair is a significant clinical challenge.
• Postoperative residual dissection is independently associated with the need for reintervention.
• Intensified clinical monitoring and personalized care at aortic centers are imperative.
