What is an Aortic Dissection (Type A)?
An Aortic Dissection (Type A) occurs when a tear in the inner aortic lining lets blood into the wall, creating a false lumen. Type A involves the ascending aorta and may extend to the aortic root, arch, coronary arteries, or major branches. It can cause serious complications such as rupture, cardiac tamponade, aortic valve leakage, coronary obstruction, stroke, or organ malperfusion. Because it is life-threatening, acute Type A dissection requires immediate emergency surgical evaluation and treatment.
What is the Importance of Timely Treatment?
Type A aortic dissection is a medical emergency. Delayed treatment can increase the risk of life-threatening complications, including aortic rupture, cardiac tamponade, severe aortic regurgitation, myocardial infarction, stroke, kidney injury, intestinal ischaemia, spinal cord injury, and limb ischaemia. Early diagnosis also allows doctors to assess the extent of the dissection and identify involvement of the aortic root, valve, coronary arteries, arch, or other major vessels.
What are the Common Symptoms of an Aortic Dissection (Type A)?
- Sudden, severe chest pain
- Sharp, tearing, or pressure-like chest pain
- Pain spreading to the back, neck, jaw, or abdomen
- Sudden shortness of breath
- Fainting or near-fainting
- Sweating, weakness, or severe anxiety
- Rapid or irregular heartbeat
- Symptoms of stroke, such as weakness, difficulty speaking, or facial drooping
- Weakness, numbness, or pain in a limb due to reduced blood flow
- Unequal blood pressure or pulses between limbs
Causes and Risk Factors of Aortic Dissection (Type A)
Causes
- Long-standing or severe hypertension
- Aortic aneurysm or enlargement of the ascending aorta
- Genetic aortic disorders
- Marfan syndrome
- Loeys-Dietz syndrome
- Vascular Ehlers-Danlos syndrome
- Bicuspid aortic valve with associated aortic disease
- Other inherited or congenital aortic abnormalities
- Atherosclerotic or degenerative changes in the aortic wall
- Previous aortic surgery or procedures
- Significant chest trauma in selected cases
- Pregnancy-associated aortic disease in susceptible individuals
Risk Factors
- Uncontrolled or long-standing high blood pressure
- Family history of aortic disease
- Known thoracic aortic aneurysm
- Genetic connective-tissue disorders
- Bicuspid aortic valve
- Increasing age
- Smoking
- Previous aortic surgery
- Certain inflammatory or vascular disorders
- Cocaine or other stimulant exposure
- Pregnancy in individuals with certain aortic conditions
Latest Research and Technologies in the Treatment of Aortic Dissection (Type A) in Malaysia
- Advances in Type A aortic dissection care include rapid CT angiography, echocardiography, specialised aortic surgery, and intensive postoperative monitoring. Surgery may involve ascending aortic repair, aortic root or valve procedures, and hemiarch or total arch reconstruction, depending on the extent of the dissection. In selected complex cases involving the arch and descending aorta, clinicians may consider a hybrid procedure such as the frozen elephant trunk technique. Access to these procedures and individual centres' experience vary, so patients and families should confirm a hospital's capabilities directly.
Treatment options for Aortic Dissection (Type A)
Emergency Surgical Reconstruction: Acute Type A aortic dissection usually requires emergency open surgery to repair or replace the affected ascending aorta. Medical treatment to control heart rate, blood pressure, and pain is started promptly while urgent surgery is arranged, but it does not replace surgery in most acute cases.
Arch Surgery: The surgeon must choose between replacing only the arch base (hemiarch) or replacing the entire arch and reimplanting the head vessels (total arch replacement), depending on how far the tear extends.
Aortic Root and Valve Procedures: If the dissection tears backwards into the heart, it can cause severe aortic regurgitation or shear off the coronary arteries. This may require procedures such as Surgical Valve Replacement (SAVR) or a David procedure (valve-sparing root replacement).
Bentall procedure : It is an emergency, life-saving open-heart surgery performed when the aortic tear tracks backwards into the heart, destroying both the aortic root and the aortic valve leaflets.

- Clinical assessment:
- Pain assessment: Sudden-onset, severe chest or upper-back pain that radiates to the neck, jaw, or abdomen may raise suspicion.
- Blood pressure and pulse: Doctors compare blood pressure and pulses between limbs to identify differences caused by reduced blood flow.
- Heart examination: Doctors check for abnormal heart sounds, particularly signs of aortic regurgitation or fluid around the heart.
- Neurological assessment: Examination for weakness, numbness, speech difficulties, confusion, or other signs of stroke or reduced cerebral blood flow.
- Circulation and organ perfusion: Doctors assess signs of shock or reduced blood flow to the kidneys, intestines, spinal cord, or limbs.
- Medical and family history: History of hypertension, aortic aneurysm, bicuspid aortic valve, connective-tissue disorders, previous aortic surgery, or family history of aortic disease is reviewed.
- Imaging Tests:
- CT Angiography: Provides rapid, detailed imaging to identify the location, extent, and branch-vessel involvement of the dissection.
- Transoesophageal Echocardiography: Provides detailed assessment of the ascending aorta, aortic root, valves, cardiac function, and complications, particularly when bedside imaging is needed.
- Transthoracic Echocardiography: Evaluates heart function, aortic valve regurgitation, pericardial effusion, and other cardiac complications, although it cannot fully visualise the entire aorta.
- Magnetic Resonance Imaging (MRI): Provides detailed imaging of the aorta and is particularly useful for selected patients during follow-up when immediate emergency imaging is not required.
MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele-rehabilitation services designed to support Aortic Dissection (Type A) patients in Malaysia. These services include:
- Gradual walking and aerobic activity: Helps rebuild endurance and mobility under medical supervision.
- Breathing exercises: Support lung function and recovery after major surgery.
- Strength and mobility exercises: Help restore muscle strength and independence while avoiding excessive strain.
- Regular follow-up: Ongoing cardiology and aortic imaging help monitor the repaired and remaining aorta.
- Medicines for Type A aortic dissection primarily reduce stress on the aortic wall, control blood pressure and heart rate, relieve pain, and manage complications, but they do not replace emergency surgery in acute cases. Treatment may include beta-blockers, intravenous antihypertensives, other antihypertensives, analgesics, diuretics, and, when indicated, anticoagulants or antiplatelet medicines.
