Thoracic Aortic Aneurysm
✓ VERIFIED AGAINST 38 C.F.R.§ 4.104 (Cardiovascular system) · reviewed 2026-05-15 · ClaimRecon Editorial Team
Thoracic Aortic Aneurysm is rated by the U.S. Department of Veterans Affairs under DC 7110 of 38 CFR § 4.104, DC 7110 across 4 severity tiers (10% / 30% / 60% / 100%). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
OVERVIEW
Aneurysm of the thoracic (chest) portion of the aorta, potentially affecting the aortic valve and branches
RATING CRITERIA (4 LEVELS)
10%
Workload of greater than 7 METs but not greater than 10 METs results in dyspnea, fatigue, angina, dizziness, or syncope; or continuous medication required.
30%
Workload of greater than 5 METs but not greater than 7 METs results in dyspnea, fatigue, angina, dizziness, or syncope; or evidence of cardiac hypertrophy or dilatation on EKG, echocardiogram, or X-ray.
60%
More than one episode of acute congestive heart failure in the past year; or workload of greater than 3 METs but not greater than 5 METs results in dyspnea, fatigue, angina, dizziness, or syncope; or left ventricular dysfunction with ejection fraction of 30 to 50 percent.
100%
Chronic congestive heart failure; or workload of 3 METs or less results in dyspnea, fatigue, angina, dizziness, or syncope; or left ventricular dysfunction with ejection fraction of less than 30 percent.
KEY EVIDENCE TO GATHER
-Service treatment records showing injury or complaints
-Imaging (X-ray, MRI, CT)
-Range of motion measurements
-Flare-up documentation per Sharp v. Shulkin
-Buddy statements describing limitations
-Prescription history
-Physical therapy records
-Employment impact documentation
C&P EXAM TIPS (6)
1.Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.
2.Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.
3.Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.
4.Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).
5.If you use assistive devices (brace, cane), bring them.
6.Describe daily activity impact: work, sleep, household tasks.
