What would normal average size in cm be for aortic root,descending aorta and a ratio between ascending and descending aorta in a normal average 50 year old man? The mean normal value for the aortic root annulus in men is 2.6 cm and for the proximal ascending aorta 2.9 cm . The upper normal limit for the ascending aorta is 2.1 cm/m2. A value beyond 4 cm is regarded as an aneurysm, a lower value as ectasia. The normal value for the descending aorta is 1.6 cm/m2 for BSA, and aneurysm is present when a value of 3 cm is exceeded. The aortic diameter gradually increases over time.
