ER Misdiagnosis of Aortic Dissection: A Guide to NY Emergency Malpractice

What Is Aortic Dissection?

Aortic dissection is a life-threatening condition in which the inner layer of the aorta (the large blood vessel branching off the heart) tears. Blood surges through the tear, causing the inner and middle layers of the aorta to separate (dissect). If the dissection progresses, it can block blood flow to major organs (brain, heart, kidneys, intestines, legs) or cause the aorta to rupture, which is often fatal.

There are two types of aortic dissection, classified by the Stanford system:

• Type A dissection: Involves the ascending aorta (the portion closest to the heart). This is a surgical emergency requiring immediate repair. The mortality rate without surgery is extremely high.
• Type B dissection: Involves the descending aorta (the portion farther from the heart). This may be managed medically (blood pressure control) or surgically, depending on complications.

Why Aortic Dissection Is So Frequently Misdiagnosed

Aortic dissection is frequently misdiagnosed for several reasons:

• Symptoms mimic more common conditions: The classic symptom -- sudden, severe chest pain that radiates to the back -- can mimic a heart attack, pulmonary embolism, or musculoskeletal pain. [Link to: /medical-malpractice/heart-attack-misdiagnosis] [Link to: /misdiagnosis/pulmonary-embolism-misdiagnosis]
• Atypical presentations: Some patients present with abdominal pain (if the dissection involves the abdominal aorta), neurological symptoms (if it involves the carotid arteries), or leg pain (if it blocks blood flow to the legs).
• Normal ECG and cardiac enzymes: Unlike a heart attack, an aortic dissection may not cause ECG changes or elevated cardiac enzymes, leading the ER doctor to rule out cardiac causes.
• Normal chest x-ray: While a widened mediastinum on chest x-ray is a classic sign, it may be absent or subtle. [Link to: /radiology-errors/x-ray-malpractice]
• Failure to order a CT scan: The definitive diagnostic test for aortic dissection is a CT scan with contrast. If the ER doctor does not order a CT scan, the diagnosis may be missed. [Link to: /radiology-errors/ct-scan-negligence]
• Failure to consider the diagnosis: Aortic dissection is relatively rare, and ER doctors may not consider it in patients with chest pain, particularly younger patients or patients without typical risk factors.
• Diagnostic anchoring: Once the ER doctor anchors on a diagnosis (e.g., heart attack, muscle pain), they may stop considering other diagnoses.
• Time pressure: ER doctors are under pressure to make decisions quickly, which can lead to cognitive errors and premature closure of the diagnostic process.

Symptoms of Aortic Dissection

The symptoms of aortic dissection can vary, but the classic presentation includes:

• Sudden, severe chest pain: Often described as tearing, ripping, or shearing. The pain may radiate to the back, neck, jaw, or abdomen.
• Pain that migrates: The pain may move from the chest to the back or abdomen as the dissection progresses.
• Blood pressure difference: A significant difference in blood pressure between the arms (greater than 20 mmHg) is a sign of dissection.
• Pulse deficit: A weak or absent pulse in one arm or leg compared to the other.
• Neurological symptoms: Stroke, weakness, numbness, or altered mental status if the dissection involves the carotid arteries. [Link to: /medical-malpractice/stroke-misdiagnosis]
• Syncope (fainting): Sudden loss of consciousness can occur.
• Shortness of breath: May occur if the dissection causes heart failure or cardiac tamponade.
• Abdominal pain: If the dissection involves the abdominal aorta.
• Leg pain or weakness: If the dissection blocks blood flow to the legs.

Conditions Commonly Confused with Aortic Dissection

Aortic dissection is frequently misdiagnosed as:

• Acute myocardial infarction (heart attack): The most common misdiagnosis. Both conditions cause sudden chest pain, but aortic dissection pain is more likely to be tearing and to radiate to the back. [Link to: /medical-malpractice/heart-attack-misdiagnosis]
• Musculoskeletal chest pain: Chest pain may be attributed to muscle strain or costochondritis.
• Gastroesophageal reflux disease (GERD): Chest pain may be attributed to acid reflux.
• Pulmonary embolism: Both conditions cause chest pain and shortness of breath. [Link to: /misdiagnosis/pulmonary-embolism-misdiagnosis]
• Stroke: If the dissection involves the carotid arteries, the patient may present with stroke-like symptoms. [Link to: /medical-malpractice/stroke-misdiagnosis]
• Pericarditis: Inflammation of the sac around the heart can cause chest pain.
• Abdominal conditions: If the dissection involves the abdominal aorta, the patient may present with abdominal pain attributed to kidney stones, gallstones, or gastroenteritis.

The Standard of Care for Diagnosing Aortic Dissection

The standard of care for diagnosing aortic dissection in the emergency room includes:

• Considering the diagnosis: The ER doctor must consider aortic dissection in any patient presenting with sudden, severe chest pain, particularly if the pain is tearing or radiates to the back.
• Obtaining a thorough history: Including risk factors (hypertension, connective tissue disorders like Marfan syndrome, family history of aortic disease, recent cocaine use, pregnancy).
• Performing a physical examination: Including checking for blood pressure differences between the arms, pulse deficits, neurological deficits, and heart murmurs (aortic regurgitation).
• ECG: An ECG should be obtained to evaluate for heart attack, but a normal ECG does not rule out aortic dissection.
• Chest x-ray: A chest x-ray may show a widened mediastinum, but a normal chest x-ray does not rule out aortic dissection. [Link to: /radiology-errors/x-ray-malpractice]
• CT scan with contrast: The definitive diagnostic test for aortic dissection. If the ER doctor suspects aortic dissection, a CT scan with contrast should be ordered emergently. [Link to: /radiology-errors/ct-scan-negligence]
• Transesophageal echocardiogram (TEE): If the patient is too unstable for a CT scan, a TEE may be performed in the emergency room or operating room.
• Consultation: If aortic dissection is suspected or confirmed, immediate consultation with cardiothoracic surgery is required.

When Misdiagnosis of Aortic Dissection Constitutes Malpractice

Misdiagnosis of aortic dissection constitutes medical malpractice in New York when the ER doctor (or other provider) deviated from the accepted standard of care and that deviation caused harm. This includes:

• The ER doctor failed to consider aortic dissection in a patient with sudden, severe chest pain.
• The ER doctor failed to obtain a thorough history, including risk factors for aortic dissection.
• The ER doctor failed to perform an appropriate physical examination, including checking for blood pressure differences and pulse deficits.
• The ER doctor failed to order a CT scan with contrast when aortic dissection was suspected.
• The ER doctor misdiagnosed the condition as a heart attack, musculoskeletal pain, or gastrointestinal issue without ruling out aortic dissection.
• The radiologist misinterpreted the CT scan. [Link to: /radiology-errors/ct-scan-negligence]
• The ER doctor failed to consult cardiothoracic surgery when aortic dissection was suspected or confirmed.
• The deviation caused harm (the dissection progressed, the patient suffered stroke or paralysis, the patient required emergency surgery, or the patient died).

Proving Your Aortic Dissection Misdiagnosis Case

To prove an aortic dissection misdiagnosis case, you need:

• Medical records: Including emergency department records, ECG, cardiac enzymes, imaging studies, operative reports, and consultation notes. [Link to: /resources/how-to-get-medical-records-for-a-lawsuit]
• Imaging studies: Chest x-ray, CT scan with contrast, and any other imaging. [Link to: /radiology-errors/ct-scan-negligence] [Link to: /radiology-errors/x-ray-malpractice]
• Expert review: Independent review by board-certified emergency medicine physicians, cardiologists, and cardiothoracic surgeons.
• Standard of care evidence: Establishing what the standard of care requires for a patient presenting with symptoms of aortic dissection.
• Causation evidence: Establishing that the deviation caused harm -- for example, that earlier diagnosis and treatment would have prevented the dissection from progressing, prevented stroke or paralysis, or prevented death.
• Expert testimony: From qualified experts.

New York Statute of Limitations

Aortic dissection misdiagnosis claims are subject to the 2.5-year statute of limitations for medical malpractice (CPLR 214-a), running from the date of the negligent act.

Key considerations:

• Date of the negligent act: The 2.5-year clock starts on the date of the ER visit (the date of the misdiagnosis).
• Continuous treatment doctrine: If you continued to receive treatment from the same hospital or provider for the same condition, the statute may be extended.
• Municipal hospitals: If the misdiagnosis occurred at a municipal hospital (NYC Health + Hospitals), a notice of claim must be filed within 90 days, and the lawsuit within 1 year and 90 days. [Link to: /hospital-negligence/suing-nyc-h-h]
• Wrongful death: If the misdiagnosis caused death, the wrongful death claim must be filed within 2 years of the date of death. [Link to: /wrongful-death-lawyer]

Common Defense Arguments and How We Counter Them

Defense: Aortic dissection is a rare condition that is difficult to diagnose.

Defense attorneys use several arguments in aortic dissection misdiagnosis cases:

• Our Counter: While aortic dissection is relatively rare, the standard of care requires ER doctors to consider it in any patient presenting with sudden, severe chest pain, particularly if the pain is tearing or radiates to the back. The standard of care also requires ordering a CT scan with contrast when aortic dissection is suspected. If the ER doctor failed to consider the diagnosis or failed to order a CT scan, the standard of care was breached.

Defense: The patient symptoms were atypical.

Our Counter: Aortic dissection can present atypically, but the standard of care requires the ER doctor to consider a broad differential diagnosis in patients with chest pain, particularly when the pain is sudden and severe. If the ER doctor anchored on a single diagnosis (e.g., heart attack) without considering other possibilities, the standard of care was breached.

Defense: Even with earlier diagnosis, the outcome would have been the same.

Our Counter: Aortic dissection is a surgical emergency, and earlier diagnosis and treatment can be life-saving. We use expert testimony from cardiothoracic surgeons to establish that earlier diagnosis and treatment would have changed the outcome -- for example, that the dissection would not have progressed, that stroke or paralysis would have been prevented, or that death would have been avoided.

Defense: The patient had risk factors that made the outcome inevitable.

Our Counter: While risk factors (hypertension, connective tissue disorders) increase the risk of aortic dissection, they do not excuse a failure to diagnose. If the patient had risk factors, the ER doctor should have been even more vigilant in considering aortic dissection.
