Acute Type A Aortic Dissection and the Consequences of a Patent False Lumen

A good discussion on the concepts of:
1. aortic true lumen and false lumen behavior after repair of acute Type A aortic dissection2. distal anastomotic new entry tear after hemiarch repair3. impact of above on clinical outcomes4. strategies on preventing distal anastomotic entry tear 
The authors communicate that improved understanding of these hemodynamic conditions may serve to improve surgical technique, guide creation of novel devices toward new therapeutic targets, reduce surgical risk, and ultimately improve patient outcomes.
