5. University of Lübeck Department of Cardiac and Thoracic Vascular Surgery Methods: All operations for type A aortic dissection performed since 1993 were identified and follow up information was gathered by contacting the patient and/or his/her physician. Results were compared using Kaplan-Meier curves. Utilizing complex surgical aortic root procedures in acute type A aortic dissection is still a matter of debate. We reviewed the midterm results in our institution.

6. University of Lübeck Department of Cardiac and Thoracic Vascular Surgery Techniques 86 operations were performed:  37 valve reimplantation procedures (David, 38%)  29 valve remodeling procedures (Yacoub, 30%)  27 valve / ascending aortic conduits (Bentall, 31%)

7. University of Lübeck Department of Cardiac and Thoracic Vascular Surgery Survival (Kaplan-Meier) Bentall David Yacoub p=0.755

8. University of Lübeck Department of Cardiac and Thoracic Vascular Surgery Results In hospital mortality:  18,5 % in the Bentall group  13,5 % in the David group and  6,9 % in the Yacoub group

9. University of Lübeck Department of Cardiac and Thoracic Vascular Surgery Results Probability of survival and freedom from aortic reoperation at ten years was:  58 % in the Bentall group  53 % in the David group and  45 % in the Yacoub group

10. University of Lübeck Department of Cardiac and Thoracic Vascular Surgery Results Probability of survival and freedom from aortic reoperation at ten years was:  58 % in the Bentall group  54 % in the David group and  45 % in the Yacoub group No difference according to the type of surgery performed (p=0.755)

11. University of Lübeck Department of Cardiac and Thoracic Vascular Surgery Conclusion  When tailored to the specific pathology, aortic valve sparing procedures in comparison to the gold standard Bentall procedure for treatment of the aortic root in type A aortic dissections yield satisfying midterm results regarding survival and freedom of reoperation.
