Understand the body’s main artery
Aortic
Disease
The aorta carries blood from the heart to every organ. Aortic disease may remain silent for years, yet an acute aortic event can become life-threatening within minutes.
Know the anatomy
One continuous artery, several regions.
The location and extent of disease influence surveillance, procedural planning and the team involved in treatment.
Aortic root
Connects the left ventricle and aortic valve to the ascending aorta; the coronary arteries originate here.
Ascending aorta
Travels upward from the heart before becoming the arch.
Aortic arch
Curves over the heart and gives branches to the head and arms.
Descending and abdominal aorta
Continues through the chest and abdomen to supply the organs and legs.
Anatomical plates and clinical figures are taken from the supplied cardiovascular surgery textbooks—not generated by AI.
Main disease patterns
Different problems require different plans.
Select a condition to view its clinical image and key meaning.
Aortic aneurysm
An abnormal enlargement caused by weakening of the aortic wall. It may occur in the chest or abdomen and often causes no symptoms.
Imaging and assessment
Measure consistently. Follow over time.
Echocardiography, CT angiography and cardiac MRI are complementary. The same anatomical level and reproducible technique matter when comparing measurements.
- 01Clinical and family history
Symptoms, blood pressure, valve disease, relatives with aneurysm/dissection and syndromic features.
- 02Define the anatomy
Identify affected segments, branch involvement and establish a reliable baseline diameter.
- 03Assess growth and risk
Repeat imaging at an individualized interval; rapid growth and associated conditions change decisions.
- 04Multidisciplinary review
Complex disease benefits from an experienced aortic team including imaging, cardiology, genetics, surgery and endovascular specialists.
Long-term aortic care
Protect the aorta today—and for life.
Surveillance, risk reduction and timely intervention are parts of one continuous plan.
Surveillance imaging
Frequency depends on location, size, growth, cause and family history. Keep copies of previous measurements and reports.
Consistency is essential when comparing studies.Blood pressure and risk
Take prescribed medication, avoid smoking and manage cardiovascular risk factors. Exercise and lifting advice should be individualized.
Ask your clinician for a safe activity plan.Surgery or endovascular repair
Timing depends on symptoms, anatomy, diameter, growth, body size, genetic diagnosis and procedural risk. Options may include open surgery, TEVAR or a hybrid strategy.
An experienced aortic team should guide the choice.
Treatment is tailored to anatomy.
Open repair remains essential for many root, ascending and arch conditions. Endovascular or hybrid repair may be suitable for selected descending and thoracoabdominal disease. The goal is durable exclusion or replacement of the diseased segment while protecting the heart, brain, spinal cord and major branches.
Ask whether relatives should be screened.
Genetic counselling and imaging of first-degree relatives may be appropriate when thoracic aortic disease, bicuspid aortic valve or an inherited condition is suspected.
Prepare for your visit
Six useful questions to ask.
Which segment of my aorta is affected?
What is the maximum diameter and how was it measured?
Has the aorta changed compared with previous imaging?
Which symptoms require emergency help?
Should I modify exercise or heavy lifting?
Should my relatives have imaging or genetic assessment?
Frequently asked questions
Clear answers to common concerns.
Can an aortic aneurysm cause no symptoms?+
Yes. Many aneurysms are discovered incidentally. Once disease is identified, planned imaging surveillance is important even when you feel well.
Does every aneurysm need surgery?+
No. Many aneurysms are monitored. Intervention is individualized using symptoms, location, diameter, growth, cause, body size and overall procedural risk.
Can I exercise with aortic disease?+
Regular moderate activity may be appropriate, but advice about heavy isometric exertion and lifting must be tailored to your aortic condition and blood pressure.
Why might my family need testing?+
Some thoracic aortic diseases cluster in families. Identifying relatives at risk allows earlier surveillance and prevention.
What is the difference between an aneurysm and a dissection?+
An aneurysm is enlargement of the aorta. A dissection begins with separation of the aortic wall layers by blood and may occur with or without a pre-existing aneurysm.
