Pulmonary atresia synonyms

Pulmonary atresia is a congenital heart defect characterized by the absence of a properly formed pulmonary valve, which prevents blood from flowing from the right ventricle to the lungs. While the condition is most commonly referred to as pulmonary atresia, it is sometimes classified based on its association with other defects, such as pulmonary atresia with intact ventricular septum (PA/IVS) or pulmonary atresia with ventricular septal defect (PA/VSD).

What are the common synonyms and terminology for pulmonary atresia?

In medical literature, pulmonary atresia is the standard clinical term used to describe the total obstruction of the pulmonary valve. Because this condition frequently occurs alongside other cardiac anomalies, synonyms often include descriptive phrases that specify the anatomical context. You may encounter the following names in medical records or historical texts:

• Pulmonary valve atresia: A formal, anatomically precise synonym.


• Atresia of the pulmonary artery: An older term sometimes used to describe the condition when the obstruction extends into the pulmonary trunk.


• PA/IVS: An abbreviation for pulmonary atresia with an intact ventricular septum.


• PA/VSD: An abbreviation for pulmonary atresia with a ventricular septal defect (often associated with Tetralogy of Fallot variants).


• Congenital pulmonary valve obstruction: A broader descriptive term occasionally found in pediatric cardiology.

Why does pulmonary atresia have multiple names?

The variety of names for pulmonary atresia stems from the fact that it is rarely an isolated anomaly. Historically, physicians classified the disease based on the presence or absence of a ventricular septal defect (a hole in the heart wall). Because the physiological management and surgical requirements differ significantly between these subtypes, medical professionals often use the specific subtype name to guide treatment. Furthermore, as diagnostic imaging has evolved, classification systems like the ICD-10 (Q22.0) and Orphanet (ORPHA:69263) have refined these labels to better reflect the underlying embryological development of the heart.

How is pulmonary atresia classified in official databases?

Standardized medical systems utilize specific codes to ensure consistency in clinical documentation and research. In the International Classification of Diseases (ICD-10), pulmonary atresia is categorized under code Q22.0. In the Online Mendelian Inheritance in Man (OMIM) database, it is often referenced within the context of complex congenital heart malformations (OMIM #187500). Being aware of these codes can be particularly helpful when navigating insurance or coordinating care between specialists, as 31 members of the DiseaseMaps.org community have found that clear terminology helps in communicating their specific cardiac history to new care teams.

Which name should patients and families use?

While you may see historical terms like "pulmonary artery atresia" in older records, pulmonary atresia remains the current, preferred term used by pediatric cardiologists and surgeons globally. When discussing your diagnosis, it is most helpful to use the specific anatomical description provided by your cardiology team, such as whether it is "with intact septum" or "with ventricular septal defect." Using the term pulmonary atresia alongside these specific descriptors ensures that your medical team is aligned on the exact nature of your or your child's heart structure.

Next steps

• Consult a pediatric cardiologist or a congenital heart surgeon to confirm the specific subtype of your pulmonary atresia.


• Request a copy of your echocardiogram or cardiac MRI reports, which will contain the official terminology used by your diagnostic team.


• Connect with the 31 other members of the DiseaseMaps.org community to share experiences and learn about patient-centered resources.


• Monitor for updates through the NIH GARD portal to stay informed about the latest research and clinical trials regarding congenital heart defects.
