The document provides expert consensus recommendations for surgical intervention thresholds for aortic dilatation in patients with bicuspid aortic valves (BAVs), focusing on ascending and descending aorta diameters.

Year: 2008

Study Type: Expert consensus

Study Size (N): N/A

Inclusion Criteria: N/A

Exclusion Criteria: N/A

Endpoints: N/A

Study Limitations and Adverse Events: Most databases have fewer patients with diameter in 5.0–5.5 cm size.

Conclusions: Surgical treatment recommended at 5.5 cm diameter for ascending and 6.5 cm for descending aorta to prevent complications. For Marfan’s syndrome or a BAV, 15% of dissections occur at ascending aorta diameter of 5.0 cm. Dividing the ascending aorta maximal cross-sectional area by pt height and using threshold of 10 recommended for indication of operation. At high experience facilities, it has been suggested for asymptomatic pts (with connective tissue disorders, chronic aortic dissection with increased growth rate) to use <5 cm for ascending and <6 cm for descending aorta and thoracoabdominal aorta as criteria. No evidence that asymptomatic aneurysms <5.5 cm benefit from repair.
