How do I know if I have Pectus excavatum?

Pectus excavatum is a structural condition characterized by a sunken appearance of the breastbone (sternum), which can typically be identified through visual inspection of the chest wall. While many individuals with pectus excavatum remain asymptomatic, diagnosis is confirmed by a physician through clinical examination and imaging studies that evaluate the depth of the depression and its potential impact on heart and lung function.

What are the early signs and symptoms of pectus excavatum?

The hallmark of pectus excavatum is a visible depression in the center of the chest, which may be present at birth or become more pronounced during the rapid growth spurts of puberty. While the primary indicator is physical, some individuals experience secondary symptoms due to the reduced space in the chest cavity. Common reports from the 81 members of our DiseaseMaps community include exercise intolerance, shortness of breath, chest pain, or a rapid heartbeat (tachycardia). It is important to note that the severity of the physical indentation does not always correlate directly with the severity of the symptoms.

How can I perform a self-assessment for pectus excavatum?

You can often identify the physical signs of pectus excavatum by standing in front of a mirror with your shirt off. Look for a concave or "caved-in" appearance of the sternum. To differentiate between normal anatomical variation and pectus excavatum, consider the following checklist:

• Visual Depth: Is there a clear, inward dip of the breastbone compared to the surrounding rib cage?


• Symmetry: Does the depression appear centered, or is it deeper on one side (which may suggest pectus carinatum or scoliosis)?


• Postural Changes: Does the appearance change significantly when you stand up straight versus slouching?


• Physical Impact: Do you notice that your breathing becomes labored during moderate physical activity?

When should I see a doctor and what tests should I request?

If you suspect you have pectus excavatum, you should schedule an appointment with a primary care physician to discuss your concerns. Be specific about your symptoms; mention if you experience palpitations, fatigue, or chest discomfort. If your doctor confirms a physical deformity, they may refer you to a thoracic surgeon or a pediatric specialist. The standard diagnostic pathway typically includes:

1. Chest X-ray: To assess the position of the heart and lungs.


2. Echocardiogram: To determine if the sternum is compressing the heart or affecting valve function.


3. Pulmonary Function Tests (PFTs): To measure how well your lungs are expanding.


4. CT Scan or MRI: Often used to calculate the "Haller Index," a numerical ratio that determines the severity of the pectus excavatum by comparing the width of the chest to the distance between the spine and the sternum.

What are the red flags requiring urgent evaluation?

While pectus excavatum is often a lifelong condition managed through observation or surgery, seek immediate medical attention if you experience sudden, severe chest pain, fainting spells during exercise, or unexplained blue tinting of the lips or fingernails. These may indicate that the heart or lungs are under significant pressure and require urgent intervention.

How can I advocate for myself if my concerns are dismissed?

If your symptoms are dismissed as "purely cosmetic," it is vital to advocate for a comprehensive functional assessment. Ask your provider, "While the appearance is cosmetic, how can we objectively rule out cardiopulmonary compression?" If you are not satisfied, request a referral to a thoracic surgeon who specializes in chest wall deformities. You are the best expert on your own body, and your quality of life is a valid reason for clinical investigation.

Next steps

• Schedule an appointment with your primary care provider to document your symptoms.


• Keep a symptom diary for two weeks to track instances of shortness of breath or chest pain.


• Join the pectus excavatum community at DiseaseMaps.org to connect with others who have navigated the diagnostic process.


• Prepare a list of your specific concerns to bring to your specialist appointment.
