Why the study?
To compare aortic valve replacement combined with ascending aorta replacement under hypothermic circulatory arrest to avoid aortic cross-clamping versus cases where cross-clamping was feasible.
Does aortic valve replacement combined with ascending aorta replacement under hypothermic circulatory arrest improve outcomes in patients with shaggy/calcified aorta compared to standard cross-clamping?
Does aortic valve replacement combined with ascending aorta replacement under hypothermic circulatory arrest improve outcomes in patients with shaggy/calcified aorta compared to standard cross-clamping?
Aortic valve replacement combined with ascending aorta replacement under profound hypothermic circulatory arrest is a feasible and safe approach for patients with severe ascending aortic lesions that preclude standard cross-clamping.
