It makes the chest jut out. This happens because of an unusual growth of rib and breastbone (sternum) cartilage .</p> <p>The bulging gives the chest a birdlike appearance. That's why the condition is sometimes called pigeon breast or pigeon chest.</p> <p><img class="right" title="" src="" alt="Illustration: Pectus carinatum causes the chest to jut out." /></p> <h3>What Causes Pectus Carinatum?</h3> <p>Doctors don't know exactly what causes pectus carinatum (PEK-tus kair-ih-NOT-um). In some cases, it runs in families.</p> <p>Kids who have it often have another health condition, such as:</p> <ul> <li><a href="">Down syndrome</a>: a genetic disorder caused by the presence of all or part of an extra copy of chromosome 21</li> <li>Edwards syndrome : a genetic disorder caused by the presence of all or part of an extra 18th chromosome</li> <li><a href="">Marfan syndrome</a>: a disorder that affects the body's connective tissue </li> <li>homocystinuria: a disorder that involves a problem with an amino acid that the body uses to make protein and build tissues</li> <li><a class="kh_anchor">Morquio syndrome</a>: unusual growth, development, shape, or integrity of the bones and cartilage. It often causes&nbsp;<a href="">dwarfism</a>.</li> <li><a href="">osteogenesis imperfecta</a>&nbsp;(brittle bone disease): this condition makes bones very fragile</li> </ul> <h3>What Are the Signs &amp; Symptoms of Pectus Carinatum?</h3> <p>A pushed-out chest is the chief sign of pectus carinatum. This usually doesn't appear until a child is age 11 or older, even though the condition is present at birth.</p> <p>The chest wall surrounds and protects the <a href="">heart</a> and <a href="">lungs</a>. So kids and teens with pectus carinatum may:</p> <ul> <li>feel short of breath, especially during exercise</li> <li>have a fast heartbeat</li> <li>feel tired</li> <li>have chest pain</li> </ul> <p>Some can develop <a href="">asthma</a> or get a lot of respiratory infections.</p> <p><img class="right" title="" src="" alt="Illustration: Pectus Carinatum showing the heart and lungs inside of the ribcage." /></p> <p>Pectus carinatum can affect one side of the chest more than the other. Sometimes, kids have pectus carinatum on one side of the chest, and a different chest wall disorder — <a href="">pectus excavatum</a>&nbsp;— on the other side. Pectus excavatum makes the chest look sunken.</p> <p>The condition gets worse as kids grow, and affects boys more often than girls.</p> <h3>How Is Pectus Carinatum Diagnosed?</h3> <p>Health care providers diagnose pectus carinatum based on an exam and a child's medical history . If needed, they might also order tests such as:</p> <ul> <li><a href="">chest X-ray</a> to check the severity of the condition</li> <li>imaging scans like <a href="">computed tomography (CT)</a> or <a href="">magnetic resonance imaging (MRI)</a></li> <li><a href="">electrocardiogram</a> to see how the heart is working</li> <li>pulmonary function tests to check the lungs</li> <li><a href="">genetic testing</a> to look for related syndromes</li> </ul> <h3>How Is Pectus Carinatum Treated?</h3> <p>Kids and teens with mild pectus carinatum might not have breathing problems or worry about their appearance. If so, they don't need treatment.</p> <p>Kids whose bones are still growing can wear a <a href=""><strong>chest brace</strong></a>. Much like how&nbsp;<a href="">braces</a> realign teeth, a chest brace will push the breastbone back to a normal position. Kids need to wear a brace for 6 months to a year. They can remove it for sports, showering, and other activities, but usually must wear it for 8 hours a day or longer.</p> <p>In some cases, surgery can treat pectus carinatum. In the <a href=""><strong>Ravitch procedure</strong></a>, a surgeon:</p> <ul> <li>removes damaged cartilage</li> <li>repairs or reshapes the sternum</li> <li>places a bar (or bars) in the chest wall to hold it in the proper position</li> </ul> <p>The surgeon removes the bar in a later surgery, usually after about 6 months. The Ravitch procedure is most often used for patients 13 to 22 years old.</p> <p>Doctors also might recommend <a href="">physical therapy</a> and exercises to strengthen weak chest muscles.</p> <h3>Looking Ahead</h3> <p>Mild pectus carinatum won't need treatment if doesn't affect how the lungs or heart work. But when the condition is very noticeable or causes health problems, a person's <a href="">self-image</a> can suffer. In those cases, treatment can improve a child's physical and emotional well-being.</p> <p>Most kids and teens who wear a brace or undergo surgery do very well and are happy with the results.</p>Trastorno de la pared torácica: pectus carinatumEl pectus carinatum es una malformación genética en el pecho, donde la pared torácica sobresale hacia fuera.
