Disease category
Congenital heart defects are a group of diseases characterized by abnormalities in the heart structure from birth, which can occur in various areas such as the heart walls, valves, and great vessels.
Core mechanism
The causes are unknown in many cases, but genetic changes may be involved, and factors such as diabetes, phenylketonuria, and rubella before or during pregnancy, smoking, exposure to certain drugs, and family history can be related factors.
Main causes/related factors
Structural abnormalities can affect the heart's pumping function and oxygen supply by making blood flow too slow, causing it to flow in the wrong direction, or obstructing it.
Representative manifestations
Representative patterns include holes in the heart walls, valve abnormalities, and abnormalities in the great vessels entering and leaving the heart.
Individual variation
Risks and prognosis vary for each individual depending on the type, number, and severity of the defects, genetic background, family history, and health status and exposure during pregnancy.
Diagnosis
Mild defects may persist without symptoms, but severe defects may present problems immediately after birth, and some are discovered in childhood or adulthood; cyanosis, fatigue, rapid or labored breathing, and heart murmurs may occur.
Management
Diagnosis is made through a combination of prenatal fetal echocardiography, pulse oximetry immediately after birth, physical examination and cardiac function tests, and genetic testing if necessary.
Treatment/Research Status
Since the anatomical extent and severity of the defect cannot be confirmed by screening tests or single test results alone, symptoms, physical examination, imaging, and functional tests must be interpreted together.
Read Evidence
Management consists of specialized cardiac care tailored to the type and severity of the defect, necessary procedures, surgery, medication, and long-term follow-up.
Key Precautions
Treatment is not the same for all patients and varies from observation only to catheterization, cardiac surgery, valve treatment, and drug therapy in specific situations.

At a Glance

Congenital heart defects are a group of diseases characterized by abnormalities in the heart structure from birth, which can occur in various areas such as the heart walls, valves, and great vessels.

Representative patterns include holes in the heart walls, valve abnormalities, and abnormalities in the great vessels entering and leaving the heart.

How the disease works

The causes are unknown in many cases, but genetic changes may be involved, and factors such as diabetes, phenylketonuria, and rubella before or during pregnancy, smoking, exposure to certain drugs, and family history can be related factors.

Structural abnormalities can affect the heart's pumping function and oxygen supply by making blood flow too slow, causing it to flow in the wrong direction, or obstructing it.

Variations in presentation among individuals

Risks and prognosis vary for each individual depending on the type, number, and severity of the defects, genetic background, family history, and health status and exposure during pregnancy.

The broad framework of diagnosis and management

Mild defects may persist without symptoms, but severe defects may present problems immediately after birth, and some are discovered in childhood or adulthood; cyanosis, fatigue, rapid or labored breathing, and heart murmurs may occur.

Diagnosis is made through a combination of prenatal fetal echocardiography, pulse oximetry immediately after birth, physical examination and cardiac function tests, and genetic testing if necessary.

Current status of treatment

Since the anatomical extent and severity of the defect cannot be confirmed by screening tests or single test results alone, symptoms, physical examination, imaging, and functional tests must be interpreted together.

Management consists of specialized cardiac care tailored to the type and severity of the defect, necessary procedures, surgery, medication, and long-term follow-up.

Treatment is not the same for all patients and varies from observation only to catheterization, cardiac surgery, valve treatment, and drug therapy in specific situations.

How to read clinical trials

Even if the defect has been corrected, lifelong follow-up by a cardiologist may be required; clinical trials must be interpreted by distinguishing between study type, registration status, and availability of results; the relevant registration record has no results and an unclear status.

Points to verify during clinical consultations

In clinical practice, it is important to confirm the exact type and severity of the defect, current symptoms and test results, past procedures/surgeries, medications, family history, pregnancy-related risk factors, and the necessary follow-up plan.
