What Does an Aortic Dissection Feel Like in Marfan?

An aortic dissection typically feels like a sudden, severe, tearing or ripping pain in your chest, back, or abdomen. For people with Marfan syndrome, this is a life-threatening medical emergency. If you experience these symptoms, do not drive yourself to the hospital—call 911 immediately and tell emergency responders that you have Marfan syndrome and suspect an aortic dissection.

What an Aortic Dissection Feels Like

An aortic dissection occurs when the inner layer of the aorta (the body’s main and largest artery) tears, allowing blood to surge between the layers of the vessel wall ^[1][2]. Because Marfan syndrome is caused by a genetic mutation that affects connective tissue, your blood vessels are naturally more fragile, making aortic dissection a primary life-threatening risk ^[3][4].

The hallmark symptom is pain that is:

• Sudden and severe: The pain is usually excruciating and at its absolute worst the exact moment it starts, rather than gradually building up over time ^[3].
• Tearing or ripping: Many people describe the sensation as feeling like something is physically tearing inside them.
• Located in the core: The pain is most often felt in the chest, the back (especially between the shoulder blades), or the abdomen ^[5].

While severe chest or back pain is the most common presentation, an aortic dissection can sometimes cause atypical symptoms. Depending on where the tear occurs and which blood vessels are affected, some people may experience fainting (syncope), numbness, tingling, or weakness in their arms or legs (neurological symptoms), or severe stomach pain (visceral symptoms) ^[6][7].

Your Emergency Action Plan

If you suspect you are having an aortic dissection, time is the most critical factor for survival. You must advocate for yourself assertively but cooperatively. Follow these exact steps:

1. Call 911 immediately: Do not drive yourself to the hospital, and do not let a friend or family member drive you. Paramedics need to begin life-saving stabilization while you are in transit.
2. Advocate for yourself: The moment paramedics arrive, and again when you reach the emergency room triage desk, you must explicitly state: “I have Marfan syndrome and I suspect I am having an aortic dissection.” If you are incapacitated by pain and cannot speak, hand triage staff an emergency alert card or letter from your cardiologist.
3. Bypass standard protocols: Standard emergency room protocols for sudden chest pain assume the patient is having a heart attack. Heart attack treatments often involve administering blood thinners, which can be highly dangerous—and potentially fatal—if you are actually bleeding from a torn aorta ^[8][9]. Clearly stating your Marfan diagnosis helps triage nurses and doctors realize they need to bypass the standard heart-attack pathway.
4. Urgently request a CT scan: Ask the physician to rule out a dissection with a Computed Tomography Angiography (CTA) scan of your chest, abdomen, and pelvis. This is the fastest, most robust, and most accurate way to diagnose an aortic dissection ^[10][11]. This test uses a special dye and X-rays to see how blood flows through your aorta, and its sensitivity is near 100% ^[10].
5. If you face pushback: In rare cases, an ER physician might be anchored on a heart attack diagnosis and reluctant to order a scan. If your request for a scan is refused, calmly but firmly state: “Please document in my medical chart that you are refusing to order a CTA to rule out an aortic dissection for a Marfan patient.” This frequently prompts a re-evaluation of the decision.

Preparing Ahead of Time

Because aortic dissections can progress rapidly, being prepared can save vital minutes during an emergency ^[12]:

• Carry an emergency alert: Keep a medical alert card in your wallet, or wear a medical ID bracelet. You can print official Marfan emergency alert materials directly from The Marfan Foundation.
• Keep digital records: Save a digital photo of your most recent echocardiogram report, surgical records, or a signed letter from your cardiologist on your smartphone. Knowing the current size of your aortic root is crucial information for emergency physicians ^[13].
• Train your support network: Make sure your designated emergency contact, spouse, or family members know this exact protocol. They may need to speak for you and request the CT scan if you are in too much pain to do so.
• Pregnancy precautions: If you are pregnant or recently gave birth, your risk for a dissection is significantly higher, even if your aortic measurements were previously normal ^[14][15]. You should maintain heightened vigilance for any sudden pain.
