Current controversies in the current clinical practice guidelines for thoracic aortic disease

Chronic aortic disease	Acute aortic syndrome
Indications for intervention are based only on the diameter. Uncertainty exists in anticipating the risk of rupture or dissection.	Lack of indications on when and how to replace the aortic arch. Organ malperfusion as an indication for arch/hybrid procedures has a level IIA reccomendation.
Surgery is recommended for ascending aorta aneurysm associated with bicuspid aortic valve (currently for diameters ≥55 mm).	Contraindications for surgical repair based on clinical parameters and patient conditions are not reported.
Recommentations on intervention are based only on evidence of level C.	Task force members are limited and often unbalanced in specialty groups (often in favor of cardiologists).
