Mortality and reoperations in survivors operated on for acute type A aortic dissection and implications for catheter-based or hybrid interventions.

Objective: This study investigated late outcomes (mortality, reoperations) and their associated predictors after operations for acute type A aortic dissection. The role catheter-based and hybrid interventions is discussed.

Methods: All hospital survivors operated on for acute type A aortic dissection from 1990 through 2009 were reviewed, with cross-sectional follow-up.

Mortality in acute type A aortic dissection: validation of the Penn classification.

Background: Intraoperative and in-hospital mortality after surgery for acute type A dissection depends largely on preoperative conditions, specifically the presence of localized or generalized ischemia. Recently, the Penn classification of patients with acute type A aortic dissection has been described. The primary aim was to validate the Penn classification and to investigate preoperative variables related to mortality.
