==Overview== | |||
== | |||
Pulmonary atresia is an extremely rare form of [[congenital heart disease]] in which the pulmonary valve does not form properly. This leads blood from the right side of the heart cannot go to the lungs to pick up oxygen. Also, the right ventricle and tricuspid valve are often poorly developed. Pulmonary atresia is always associated with other congenital heart disease such as [[ventricular septal defect]], [[tetralogy of Fallot]] and [[patent ductus arteriosus]]. The cause is not clear. Usual symptoms are [[cyanosis]], [[shortness of breath]], fast breathing and [[fatigue]]. [[Echocardiography]] and cardiac MRI can tell the diagnosis of pulmonary atresia. Treatments include [[prostaglandin]] E1, catheter-based procedures and surgery. Prognosis of pulmonary atresia depends on whether the surgery has been done and the severity of other associated congenital heart diseases. | Pulmonary atresia is an extremely rare form of [[congenital heart disease]] in which the pulmonary valve does not form properly.

Overview
Pulmonary atresia is an extremely rare form of congenital heart disease in which the pulmonary valve does not form properly. This leads blood from the right side of the heart cannot go to the lungs to pick up oxygen. Also, the right ventricle and tricuspid valve are often poorly developed. Pulmonary atresia is always associated with other congenital heart disease such as ventricular septal defect, tetralogy of Fallot and patent ductus arteriosus. The cause is not clear. Usual symptoms are cyanosis, shortness of breath, fast breathing and fatigue. Echocardiography and cardiac MRI can tell the diagnosis of pulmonary atresia. Treatments include prostaglandin E1, catheter-based procedures and surgery. Prognosis of pulmonary atresia depends on whether the surgery has been done and the severity of other associated congenital heart diseases.
What are the symptoms of Pulmonary atresia?
Symptoms usually occur in the first few hours of life. Symptoms may include:
- Cyanosis
- Shortness of breath
- Fast breathing
- Poor eating habits
- Fatigue
Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.
What causes Pulmonary atresia?
As with most congenital heart diseases, there is no known cause of pulmonary atresia. The condition is associated with another type of congenital heart defect called a patent ductus arteriosus (PDA).
Persons with pulmonary atresia may also have a poorly developed tricuspid valve. They may also have an underdeveloped right ventricle and abnormal blood vessels feeding the heart.
Pulmonary atresia may occur with or without a ventricular septal defect (VSD). If the person does not have a VSD, the condition is called pulmonary atresia with intact ventricular septum (PA/IVS). If the person has both problems, the condition is called pulmonary atresia with VSD. This is an extreme form of tetralogy of Fallot. Although both conditions are called pulmonary atresia, they are actually different defects.
Who is at highest risk?
Like other congenital heart diseases, the cause of pulmonary atresia is not clear. Pulmonary atresia sometimes is associated with other congenital heare diseases such as patent ductus arteriosus, ventricular septal defect and tetralogy of Fallot.
When to seek urgent medical care?
Call your health care provider if your baby has symptoms of pulmonary atresia. If one emerges the following symptoms, seeking urgent medical care as soon as possible:
Diagnosis
- Echocardiography: This kind of painless test can help the doctor closely examine pulmonary atresia. It uses sound waves to produce an image of the ventricles, atrium and great vessles. Echocardiogram can tell whether pulmonary valve opens to let blood flow through or not. Further more, the doctor can measure the speed of blood flow through patient's heart and pulmonary valve area by echocardiogram.
- Chest x-ray: An x-ray image of chest allows the doctor to check the size and shape of your heart to determine whether the left atrium and ventricle are enlarged or not. And it also helps the doctor check the condition of your lungs. Patients with pulmonary atresia may show enlarged right ventricle on an x -ray.
- Chest CT or MRI: A chest CT or MRI can demonstrate the details of the heart extremely well, such as the positions of valval, vascular, atrial and ventricular structures and their relationships to one another.
- Electrocardiogram (ECG) and Holter monitoring: Electrocardiogram and Holter monitoring detect electric activities of the heart for cardiovascular diseases. They can supply information about heart rhythm and indirectly, heart size. Patients with patent ductus pulmonary atresia may show a enlarged right ventricle sign.
Treatment options
Patients with pulmonary atresia have many treatment options. The selection depends on the size of the pulmonary artery and right ventricle, other associated heart defect and whether the child occurs the complications or not. The options are medicines, catheter-based procedures and surgery. Talk to your child's doctor about treatment options and your family's preferences on treatment decisions.
- Medicines: Prostaglandin E1 is usually used to help the blood move into the lungs.
- Catheter-based procedures: In a catheter room, the doctor threads a thin tube through a blood vessel in your baby's arm or groin to an artery in the heart and injects dye to see the heart and the arteries on an x-ray. Then a small metal coil or other blocking device is passed up through the catheter and placed to repair the defects. Complications of catheter-based procedures may include bleeding, infection and arrhythmia.
- Surgery: Surgical treatment of pulmonary atresia may be performed to repair or replace the valve. This surgery can also be used to place a tube between the right ventricle and the pulmonary arteries. During the surgery, the anesthetist gives medicine to make the child sleepy and comfortable. Then the surgeons make a small cut between the ribs to reach the heart and repair the defects and place a tube between the right ventricular and the pulmonary arteries. Most cases can be helped with surgery.
