Key result
Valved composite graft aortic root replacement shows ~7% hospital mortality for aneurysm or dissection.
Why the study?
Does prosthetic aortic root replacement with a valved composite graft provide safe and effective outcomes in patients with aortic root aneurysm or dissection?
Cohort (n=335)
Does prosthetic aortic root replacement with a valved composite graft provide safe and effective outcomes in patients with aortic root aneurysm or dissection?
Composite graft replacement of the aortic root for aneurysm or dissection demonstrates acceptable early mortality (6.6%) and good long-term survival (80% at 5 years).

Supports consideration of composite graft replacement for aortic root aneurysm or dissection; extends observational data but leaves open comparative effectiveness.
Mingke et al. (1998) conducted a cohort in Aneurysm or dissection involving the sino-tubular segment of the aorta (n=335). Replacement of the aortic root with a valved composite graft was evaluated on Hospital death. Prosthetic aortic root replacement with a valved composite graft for aneurysm or dissection resulted in a 6.6% hospital mortality rate and an actuarial survival of 80% at 5 years and 67% at 10 years.
