Congenital heart disease (CHD) is a problem with your heart's structure that occurs at birth. These difficulties that prevent regular blood flow may include:
- A hole in the heart wall.
- Blood vessel problems (too many or too few, blood flowing too slowly, to the wrong location, or in the wrong direction).
- Problems with your heart valves, which regulate blood flow.
Some CHD situations are uncomplicated and may not result in any symptoms. Others, however, are potentially fatal and necessitate early intervention. Healthcare providers can diagnose cardiac problems early on (before or shortly after delivery). However, some persons do not receive a CHD diagnosis until childhood, adolescence, or adulthood.
Types of congenital heart disease
There are two major categories of CHD:
- Cyanotic (low oxygen in the blood) congenital heart disease: These heart irregularities limit the quantity of oxygen your heart can supply to the rest of your body. Babies born with cyanotic congenital heart disease typically have low oxygen levels and require surgery. Examples include left heart obstructive lesions, right heart obstructive lesions, and mixed lesions.
- Acyanotic (blood oxygen level is acceptable) Congenital heart disease: This is a condition that causes blood to flow irregularly through your body. For example, a hole in the heart, an aortic issue, or a pulmonary artery difficulty.
Symptoms
Congenital heart disease symptoms may appear immediately after birth or later in life. They could include:
- Cyanosis refers to bluish skin, lips, or nails.
- Excessive sleepiness.
- Rapid breathing or difficulty breathing.
- Fatigue (a state of extreme tiredness).
- Experiencing unusual tiredness or shortness of breath during exercise.
- A heart murmur is a swishing sound made by your heart that can indicate abnormal blood flow.
- Poor blood circulation.
- Weak pulse or pounding heartbeat.
Causes
CHD occurs when the fetal heart does not develop normally in the uterus. Scientists do not entirely understand why this occurs; however, it could be related to:
- Having abnormal chromosomes or genetics inherited from parents or occurring at random.
- During pregnancy, avoid drinking alcohol, smoking, and being exposed to secondhand smoke.
- Taking medications during pregnancy, such as those used to treat high blood pressure, cholesterol, or acne.
- Having an illness while pregnant (diabetes, phenylketonuria, or a viral infection such as rubella).
Diagnosis
Sometimes a healthcare provider discovers a congenital problem before the baby is born. If your clinician notices anything unusual during a regular prenatal ultrasound, you and the fetus may require additional testing. A fetal echocardiography, for example, creates images of the unborn heart by using harmless sound waves.
Other heart abnormalities are detected shortly after a baby is delivered. They can, for example, use pulse oximetry to determine cyanotic CHD. The quick, painless test utilizes sensors on your baby's fingers or toes to determine whether oxygen levels are too low. Sometimes people do not receive a congenital heart defect diagnosis until later in life.
Test
The following tests can help diagnose CHD in newborns, children, and adults:
- Physical examination: A medical professional will listen to your heart during an examination to listen for any unusual sounds.
- Chest X-ray: To identify any structural abnormalities, a chest X-ray takes images of the inside of your chest.
- Electrocardiogram: An electrocardiogram, also known as an EKG or ECG, gauges your heart's electrical activity.
- Echocardiogram: An echocardiogram uses ultrasonography to produce pictures of the chambers and valves in your heart.
- Heart catheterization: A heart catheterization allows a healthcare provider to assess how properly your heart pumps and circulates blood. It is also known as cardiac catheterization or coronary angiography.
- Magnetic resonance imaging (MRI): MRI can produce fine-grained images of your heart in order to diagnose heart disease.
Treatment
Congenital heart disease treatment may involve:
- A catheter procedure to place a plug into a defect.
- Medications to help your heart work more efficiently or to manage blood pressure.
- A non-surgical procedure to fix an issue using a closing device.
- Oxygen therapy provides higher levels of oxygen than normal room air would.
- Prostaglandin E1, which relaxes smooth heart muscle and can keep open the ductus arteriosus (a blood vessel that normally closes after birth), helps provide needed circulation.
- Surgery to repair an issue, open up blood flow, or redirect blood. In severe cases, people need a heart transplant.
Some cases of CHD may not need any treatment. Others are life-threatening and need treatment soon after birth.
Complications
The complications of congenital heart disease treatment differ depending on the technique. Bleeding, infection, arrhythmia (abnormal heart rhythm), scar tissue, blood clots, aneurysm (stretched blood vessel), heart attack, and a leaking heart valve are all possible complications.
Prevention
There are no established strategies for preventing CHD. People are born with it, usually for unclear reasons. It is beyond their control. During pregnancy, you should follow the directions of your healthcare professional, which may include:
- Do not use recreational drugs.
- Take all recommended screening tests during pregnancy to detect problems as soon as possible.
- Manage any medical conditions, including diabetes and phenylketonuria.
- Stop smoking and avoid secondhand smoke.
- Avoid alcohol.
Conclusion
Congenital heart defects are a complicated and diverse set of disorders; nevertheless, with early detection, sophisticated treatment choices, and thorough care, most children with CHDs can live healthy lives. Raising awareness, funding research, and offering services to afflicted families are critical steps toward improving outcomes and assuring a brighter future for these children.
