ICD-10: Q25.42

Hypoplasia of the aorta, classified under ICD-10-CM code Q25.42, refers to a congenital condition characterized by the underdevelopment or incomplete formation of the aorta, the major artery responsible for distributing oxygenated blood from the heart to the rest of the body. This condition can lead to significant cardiovascular complications and requires careful clinical management.

Clinical Description

Definition

Hypoplasia of the aorta is defined as a structural anomaly where the aorta is narrower than normal due to insufficient growth during fetal development. This can affect any segment of the aorta, including the ascending aorta, aortic arch, or descending aorta, and may vary in severity from mild to life-threatening.

Etiology

The exact cause of aortic hypoplasia is often unknown, but it is believed to result from a combination of genetic and environmental factors. It can occur as an isolated defect or as part of a syndrome involving other congenital heart defects, such as Turner syndrome or other chromosomal abnormalities.

Symptoms

Symptoms of aortic hypoplasia can vary widely depending on the severity of the condition and the presence of associated anomalies. Common clinical manifestations may include:
- Heart Murmurs: Due to turbulent blood flow across the narrowed segment.
- Poor Growth: Infants may exhibit failure to thrive due to inadequate blood flow and oxygen delivery.
- Cyanosis: A bluish discoloration of the skin, particularly in severe cases where blood flow is significantly compromised.
- Respiratory Distress: Difficulty breathing may occur if the heart is unable to pump effectively.

Diagnosis

Diagnosis typically involves imaging studies, including:
- Echocardiography: The primary tool for visualizing the aorta and assessing its size and function.
- MRI or CT Angiography: These may be used for detailed anatomical assessment, especially in older children and adults.

Treatment

Management of hypoplasia of the aorta often requires surgical intervention, particularly in severe cases. Treatment options may include:
- Surgical Repair: Procedures to reconstruct or enlarge the narrowed segment of the aorta.
- Medications: To manage symptoms and support heart function, including diuretics and medications to improve cardiac output.
- Long-term Monitoring: Regular follow-up with a cardiologist is essential to monitor for potential complications, such as hypertension or heart failure.
