Arizona Aortic Dissection Misdiagnosis Lawyer
Written by: Hastings Law Firm | Reviewed by: Tommy Hastings | Updated: May 6, 2026
An aortic dissection is a time sensitive emergency that can be missed in the emergency room when critical symptoms are dismissed or advanced imaging is not ordered. A delayed diagnosis can allow the tear to progress quickly, leading to catastrophic injury, fatal outcomes, and profound loss for families. The condition is often mistaken for less dangerous problems, and implicit bias in triage can increase the risk of misdiagnosis for some patients. If you or a loved one were harmed or worse due to aortic dissection misdiagnosis in Arizona, contact Hastings Law Firm for a free, confidential case review.

Trusted Arizona Medical Attorneys for Aortic Dissection Negligence Claims
What You Should Know About Failure to Diagnose Aortic Dissection Claims in Arizona:
- Outcomes can be catastrophic or fatal when an aortic dissection is missed because treatment delays can rapidly worsen survival chances.
- Recovery can hinge on whether emergency staff ruled out life threatening causes of chest pain before discharge rather than anchoring on a benign explanation.
- Liability disputes often focus on whether advanced imaging was ordered when red flag symptoms were present.
- Harm can be compounded when emergency room overcrowding and long waits delay diagnostic imaging for time sensitive emergencies.
- Misdiagnosis risk can be higher for younger patients and women when implicit bias in triage leads to skipped assessments.
- Compensation can include economic and non economic losses when a missed diagnosis causes severe injury or wrongful death.
- Punitive damages may be available in rare situations involving gross negligence.
- Options can be limited if legal time limits are missed, including stricter requirements for claims involving government facilities.
- Proof can depend on qualified medical expert support regarding the standard of care and causation.
- Case clarity can depend on whether imaging was misread or subtle findings were overlooked by a radiologist or emergency physician.

What Is an Aortic Dissection and Why Is It Missed?
An aortic dissection is a life-threatening condition in which the inner layer of the aorta, the body’s largest artery, tears open. Blood forces its way between the layers of the vessel wall, sometimes complicating a pre-existing aortic aneurysm. Without rapid treatment, the aorta can rupture. This condition is frequently missed because its symptoms closely mimic less dangerous problems like heart attacks, acid reflux, or musculoskeletal pain.
The aorta runs from the heart down through the chest and abdomen. A Stanford Type A dissection involves the ascending aorta and demands emergency surgery. A Stanford Type B dissection affects the descending aorta and is sometimes managed with medication.
The urgency cannot be overstated. Research published by Oxford Academic on mortality after acute Type A aortic dissection confirms that mortality increases significantly with every hour treatment is delayed. A failure to diagnose aortic dissection within the first few hours can mean the difference between life and death.
The standard of care requires physicians to use a differential diagnosis approach, ruling out the most dangerous conditions first when a patient arrives at an ER with acute chest pain. A radiologist or ER physician should not anchor on a benign diagnosis without excluding dissection.
The Danger of Implicit Bias in Triage
Diagnostic errors regarding aortic dissection do not affect all patients equally. This condition occurs when the main artery’s inner layer tears, yet studies consistently show that younger patients and women are more likely to be misdiagnosed because they do not match an assumed profile. This implicit bias in triage can lead ER staff to skip critical assessments. When a provider’s preconceptions override clinical evidence, the result is a breach of the standard of care that can prove fatal.

Recognizing Critical Symptoms the ER Should Not Miss
Emergency rooms are expected to rule out aortic dissection when a patient presents with sudden, severe chest or back pain described as “tearing” or “ripping,” pulse deficits between extremities, or significant blood pressure differences between arms. These are red-flag presentations that should trigger immediate advanced imaging for a suspected aortic dissection.
Here are the symptoms and signs that should prompt an ER team to investigate for a dissection:
- Sudden, severe pain: Often described as a “tearing” or “riping” sensation in the chest that radiates to the back or between the shoulder blades. The onset is typically abrupt and maximal from the start, which distinguishes it from the gradual build of cardiac chest pain.
- Abdominal pain: Dissections extending into the descending aorta can cause severe abdominal pain that may be confused with gastrointestinal conditions.
- Syncope: Fainting or near-fainting episodes can occur when the dissection affects blood flow to the brain.
- Shortness of breath: Difficulty breathing may develop if blood leaks into the space around the heart or lungs.
- Neurological symptoms: Stroke-like signs, numbness, or weakness in the extremities can appear if the dissection compromises blood supply to the brain or spinal cord.
- Pulse deficit and inter-arm blood pressure differential: A pulse deficit occurs when the pulse is weaker or absent in one limb compared to the other. Checking blood pressure in both arms is a simple bedside test. A significant difference, sometimes called an inter-arm blood pressure differential, is a hallmark indicator of aortic dissection that is too often skipped during triage.
Any combination of these symptoms should put aortic dissection at the top of the differential. When ER staff fail to recognize these patterns, patients can be discharged or left waiting while the tear progresses.

How Arizona Emergency Rooms Fail to Diagnose Aortic Dissection
Malpractice in aortic dissection cases most commonly occurs when an ER physician fails to order a CT angiogram (CTA), a specialized scan that uses contrast dye to produce detailed images of the aorta’s structure, or a transesophageal echocardiogram (TEE), an ultrasound probe guided down the esophagus to visualize the heart and aorta in real time. These are the gold-standard diagnostic tools, and skipping them causes a delayed diagnosis that is a serious departure from the standard of care.
Arizona ER wait times and overcrowding can compound the problem. Data tracked through the CMS Timely and Effective Care dataset shows measurable variation in how quickly hospitals deliver diagnostic imaging and treatment. For a condition where every hour matters, long waits in the ER lobby while a dissection silently progresses can turn a survivable event into a fatal one.
The failures we investigate in these cases typically fall into identifiable patterns:
| Standard of Care | Negligent Action |
|---|---|
| Order a CT angiogram or TEE when symptoms suggest dissection | Discharge the patient with no advanced imaging |
| Interpret imaging carefully for signs of intimal tear or flap | Radiologist misreads or overlooks subtle findings on X-ray or CT |
| Prioritize triage for acute chest pain with red-flag features | Patient left in waiting area during high-volume periods |
| Apply differential diagnosis to rule out life threats | Physician anchors on “acid reflux” or “musculoskeletal pain” without excluding dissection |
If you suspect that an ER’s failure to image or properly evaluate your loved one led to a preventable death or catastrophic injury, an Arizona aortic dissection malpractice lawyer at our firm can examine the medical records and identify where the breakdown occurred. As a misdiagnosis attorney in Arizona, we know exactly what evidence to look for and how to build a case around these failures.

Proving Negligence: The Standard of Care for Chest Pain
To prove negligence, we must show that a reasonably prudent physician facing the same symptoms would have ordered diagnostic imaging to rule out an aortic dissection, and that the failure to do so caused or contributed to the patient’s injury or death.
We build each case around four elements of proof:
- Duty of care: Every ER physician has a legal obligation to evaluate patients thoroughly and rule out life-threatening conditions before discharge. This duty is non-negotiable.
- Breach of that duty: We establish breach by demonstrating that the physician did not order the standard test, a CTA or TEE, despite symptoms that warranted it. We also examine whether the differential diagnosis, a structured rule-out approach where doctors eliminate the most dangerous possibilities first, was properly applied. One critical finding our experts look for is the intimal flap, the telltale sign of a torn aortic lining visible on imaging that may have been present but overlooked.
- Causation: This is often the most contested element. We work with vascular surgeons and emergency medicine specialists to demonstrate that timely diagnosis would have led to surgical repair and a meaningful chance of survival. In fatal cases, this is sometimes framed as a “lost chance” analysis.
- Damages: We document the full scope of harm, including medical costs, lost income, pain and suffering, and wrongful death losses.
An experienced aortic dissection lawyer understands that establishing liability for medical malpractice in these cases lives or dies on expert testimony. Our firm works with top-tier vascular surgeons and board-certified ER physicians from across the country who can credibly explain to a jury what should have been done and when.

Compensation for Aortic Dissection Misdiagnosis in Arizona
Patients and families affected by a missed aortic dissection may recover both economic and non-economic damages, and in wrongful death cases, surviving family members can seek compensation for the profound personal losses they’ve endured.
Arizona law, including Article 2, Section 31 of the Arizona Constitution, protects the right to recover full damages for death or personal injuries caused by another’s negligence. The categories of compensation available in these cases generally include:
- Past and future medical expenses: Emergency surgery, ICU stays, rehabilitation, cardiac monitoring, and ongoing care related to the dissection or its complications.
- Lost income and earning capacity: Wages lost during recovery, or the full lifetime earning potential of a family member who did not survive.
- Pain and suffering: Physical pain from the dissection itself, failed or delayed surgeries, and the emotional distress of knowing the diagnosis was missed.
- Mental anguish: The psychological toll on patients who survived with catastrophic injury, or on families who watched a loved one deteriorate.
- Loss of consortium and companionship: In wrongful death claims, surviving spouses, children, and parents can seek compensation for the loss of their loved one’s presence, guidance, and support.
- Punitive damages: In rare cases involving gross negligence, Arizona courts may award punitive damages intended to deter egregious medical conduct.
Because aortic dissections carry such a high fatality rate, many of these cases involve wrongful death claims. Whether through a settlement or a jury award, our team works closely with families to document every dimension of their loss.

Frequently Asked Questions About Aortic Dissection Misdiagnosis in Arizona

Key Aortic Dissection Misdiagnosis Terms:
- Aortic dissection
- A life-threatening condition where the inner layer of the aorta (the body’s main artery) tears, allowing blood to flow between the layers of the artery wall. This causes the layers to separate and can lead to rupture. In missed diagnosis cases, it matters because mortality increases by 1-2% every hour treatment is delayed, making timely recognition critical.
- Stanford Type A and Type B aortic dissection
- A classification system that divides aortic dissections by location. Type A involves the ascending aorta (the section closest to the heart) and requires emergency surgery. Type B involves the descending aorta (farther from the heart) and may be managed with medication or surgery. Type A dissections are more immediately fatal if missed.
- Implicit bias in triage
- Unconscious assumptions or stereotypes that emergency room staff may hold about patients based on factors like race, gender, age, or appearance, which can affect how quickly or seriously their symptoms are evaluated. In aortic dissection cases, implicit bias can lead to dismissing or downplaying chest pain complaints, resulting in dangerous delays in diagnosis.
- Pulse deficit
- A condition where the pulse is weak or absent in one or more limbs compared to others, indicating that blood flow is being blocked or restricted. This is a critical warning sign of aortic dissection that emergency room physicians should check for but often miss.
- Inter-arm blood pressure differential
- A significant difference in blood pressure readings between the left and right arms, typically 15-20 mmHg or more. This is a hallmark red flag for aortic dissection and should prompt immediate further testing. Negligent care often includes failing to check blood pressure in both arms.
- CT angiogram (CTA)
- A specialized computed tomography (CT) scan that uses contrast dye to create detailed images of blood vessels, including the aorta. It is the gold standard imaging test for diagnosing aortic dissection. Failure to order a CTA when a patient presents with suspicious chest pain is a common form of emergency room negligence.
- Transesophageal echocardiogram (TEE)
- An ultrasound procedure where a probe is inserted down the esophagus to obtain high-quality images of the heart and aorta. It is used to diagnose aortic dissection when a CT scan is not available or appropriate. Failure to perform this test when indicated can constitute a breach of the standard of care.
- Differential diagnosis (rule-out approach)
- A systematic medical process where a doctor considers and eliminates the most serious or life-threatening conditions first before settling on a diagnosis. In chest pain cases, this means ruling out aortic dissection, heart attack, and pulmonary embolism before attributing symptoms to less serious causes like acid reflux. Skipping this process is a common basis for proving negligence.
- Intimal flap
- The visible torn layer of the aorta’s inner lining seen on imaging studies like a CT angiogram or echocardiogram. It appears as a flap of tissue moving within the aorta and is the definitive radiological sign of an aortic dissection. Radiologists who miss or fail to report an intimal flap may be liable for misdiagnosis.
- Mortality after non surgically treated acute type A aortic dissection is higher than previously reported | Oxford Academic
- Timely and Effective Care State | data.cms.gov
- Article 18 Section 31 Damages for death or personal injuries | Arizona State Legislature
- 12-542 Injury to person injury when death ensues injury to property conversion of property forcible entry and forcible detainer two year limitation | Arizona Legislature
