Which are the symptoms of Pectus excavatum?

Pectus excavatum is a structural chest wall deformity characterized by a concave depression of the sternum, which can compress the heart and lungs, leading to symptoms like exercise intolerance, shortness of breath, and chest pain. While the severity of pectus excavatum varies significantly among individuals, symptoms often become more pronounced during adolescent growth spurts as the rib cage develops.

What are the most common symptoms of pectus excavatum?

The primary manifestation of pectus excavatum is the visible "sunken" appearance of the chest, but the clinical impact extends beyond aesthetics. Patients often experience physiological symptoms resulting from the reduced space within the thoracic cavity. Common symptoms reported by our community of 81 members include:

• Exercise intolerance: A noticeable decrease in stamina compared to peers, often due to the heart’s inability to pump efficiently or reduced lung capacity.


• Shortness of breath (dyspnea): Difficulty catching one's breath, particularly during physical activity or exertion.


• Chest pain: Often described as sharp or pressure-like, occurring behind the sternum.


• Tachycardia: An abnormally rapid heart rate, sometimes caused by the sternum pressing against the right ventricle of the heart.


• Fatigue: Chronic tiredness resulting from the body working harder to maintain cardiovascular and respiratory function.

How does symptom severity vary among patients?

The severity of pectus excavatum is not always directly correlated with the depth of the depression. Some individuals with a deep indentation may remain asymptomatic, while others with milder depressions may experience significant physical limitations. This variability is often linked to the flexibility of the chest wall and how much the heart and lungs are physically displaced or compressed. As patients transition through puberty, rapid skeletal growth can cause a sudden worsening of pectus excavatum symptoms, making ongoing monitoring by a pediatric cardiologist or thoracic surgeon essential.

What are the early warning signs and quality of life impacts?

Early warning signs often involve subtle changes in activity levels. Parents should watch for children who consistently avoid sports, complain of chest discomfort during play, or exhibit frequent respiratory infections. For many, the most significant impact on quality of life is psychological; the physical appearance of pectus excavatum can lead to social anxiety, body image issues, and the avoidance of activities like swimming or changing clothes in locker rooms. Addressing both the physical and emotional aspects is vital for comprehensive care.

When should you seek immediate medical attention?

While pectus excavatum is generally a chronic condition, certain symptoms necessitate urgent medical evaluation. Seek immediate care if you or your child experiences:

1. Sudden, severe chest pain that does not resolve with rest.


2. Fainting or lightheadedness (syncope) during physical activity.


3. A rapid, irregular heartbeat that persists at rest.


4. Unexplained, worsening respiratory distress or difficulty breathing while lying flat.

Next steps

• Consult a thoracic surgeon or a pediatric cardiologist to assess the Haller Index, a measurement used to determine the severity of pectus excavatum.


• Track your symptoms in a diary to discuss with your specialist, noting any triggers for breathlessness or chest pain.


• Join the DiseaseMaps.org community to connect with others who have navigated the challenges of pectus excavatum and share experiences regarding treatment options.


• Request pulmonary function tests and an echocardiogram to evaluate the impact on your heart and lung function.
