Recommended indications for elective replacement of the aorta.

Indication for elective surgical replacement of the aorta	Class of recommendation	Level of evidence
≥50 mm for patients with Marfan syndrome and connective tissue disorders	I	C
≥45 mm for patients with Marfan syndrome and risk factor*	IIa	C
≥50 mm for patients with bicuspid valve and risk factor*	IIa	C
≥55 mm for all other patients	IIa	C
