Aortic valve reimplantation for aortic root aneurysms: trainer and trainee differences on long-term results.

Purpose: The advantages of aortic valve-preserving surgery are still hampered by a higher rate of reoperations compared to root replacement with valved conduits. This study evaluates whether valve deterioration rate is related to the method or depends on stringent adherence to technical concepts, which might be lost once trainees perform this complex surgery on their own.

Methods: From 1991 to 2011, the David procedure was performed in 209 consecutive patients.

Long-term results of aortic valve resuspension in patients with aortic valve insufficiency and aortic root aneurysm.

Objectives: 'The David technique' may provide an alternative to conduit implantation in patients with an aneurysm of the ascending aorta and aortic valve insufficiency.

Methods: From 1991 to 2013, the David technique was performed in 249 consecutive patients in our department. The patient mean age was 58 ± 14 years; 71 (29%) were female and 178 (71%) male.
