Heart problems in newborns can be a serious issue that requires immediate medical attention. Congenital heart defects (CHD) are the most common type of birth defect, affecting around 1 in 100 babies born in the UK. CHD is a structural problem with the heart that is present at birth and can affect the way the heart functions.
Understanding Congenital Heart Defects in Newborns is crucial for parents and healthcare professionals alike. CHD can range from minor defects that may not require treatment, to severe defects that can cause serious complications. It is important to recognise the symptoms and diagnosis of CHD in newborns to ensure that treatment and management can be provided as soon as possible.
Recognising Symptoms and Diagnosis of CHD in newborns can be challenging as some babies may not show any symptoms at all. However, some common signs of CHD in newborns include rapid breathing, poor feeding, excessive sweating, and bluish skin, lips, and nails. Diagnosis of CHD usually involves a physical examination, medical history, and various tests such as an echocardiogram, chest X-ray, or electrocardiogram. Early diagnosis and treatment can help improve the long-term outcome for babies with CHD.

Understanding Congenital Heart Defects in Newborns
Congenital heart defects are structural abnormalities of the heart that are present at birth. They are the most common type of birth defect, affecting approximately 1% of newborns. Although some heart defects may be mild and go unnoticed, others can be life-threatening and require immediate medical attention.
Types of Congenital Heart Defects
There are several types of congenital heart defects that can affect newborns. Some of the most common types include:
- Atrial septal defect (ASD): A hole in the wall that separates the two upper chambers of the heart.
- Ventricular septal defect (VSD): A hole in the wall that separates the two lower chambers of the heart.
- Atrioventricular canal defect: A combination of several heart defects that affect the walls and valves between the heart’s chambers.
- Tetralogy of Fallot: A combination of four heart defects that affect the flow of blood through the heart.
- Transposition of the great arteries: A condition in which the two main arteries leaving the heart are switched.
- Truncus arteriosus: A condition in which there is only one large blood vessel leaving the heart.
- Coarctation of the aorta: A narrowing of the main artery that carries blood from the heart to the rest of the body.
- Hypoplastic left heart syndrome: A condition in which the left side of the heart is underdeveloped.
- Pulmonary atresia: A condition in which the valve that controls blood flow from the heart to the lungs does not form properly.
Causes and Risk Factors
The causes of congenital heart defects are not always clear. However, there are several factors that can increase the risk of a baby being born with a heart defect. These include:
- Genetics: Some heart defects are inherited from a parent.
- Down syndrome: Babies with Down syndrome are more likely to have heart defects.
- Rubella: If a mother contracts rubella during pregnancy, it can increase the risk of her baby developing a heart defect.
- Diabetes: Women with diabetes are more likely to have babies with heart defects.
- Medications: Certain medications taken during pregnancy can increase the risk of heart defects.
- Alcohol and smoking: These substances can increase the risk of heart defects.
- Family history: If a parent or sibling has a heart defect, it can increase the risk of a baby being born with a heart defect.
- Prenatal care: Receiving proper prenatal care can help identify and manage risk factors for heart defects.
- Folic acid: Taking folic acid supplements before and during pregnancy can help reduce the risk of heart defects.
- Illegal drugs: Using illegal drugs during pregnancy can increase the risk of heart defects in babies.
It is important to note that not all cases of congenital heart defects have a known cause or risk factor. If a baby is born with a heart defect, it is important to work closely with a healthcare provider to determine the best course of treatment.
Recognising Symptoms and Diagnosis
Common Symptoms of Heart Problems in Newborns
Heart problems in newborns can be difficult to diagnose, as many of the symptoms are not always noticeable. However, there are some common symptoms that parents should be aware of. These symptoms include:
- Cyanosis: A bluish tint to the skin, lips, or fingernails, which is caused by a lack of oxygen in the blood.
- Shortness of breath: Difficulty breathing or rapid breathing can be a sign that the heart is not functioning properly.
- Poor weight gain: Infants with heart problems may have difficulty gaining weight or may lose weight over time.
- Fatigue: Infants with heart problems may become easily fatigued or tired.
- Swelling: Swelling in the legs, abdomen, or other areas of the body may be a sign of heart failure.
If parents notice any of these symptoms in their newborn, they should contact their healthcare provider immediately.
Diagnostic Procedures
If a healthcare provider suspects that a newborn may have a heart problem, they will perform a physical exam, which may include listening to the heart with a stethoscope. If a heart murmur is detected, the healthcare provider may order additional tests, such as an echocardiogram or chest X-ray.
An echocardiogram uses sound waves to create a picture of the heart and can help diagnose heart defects. A chest X-ray can show the size and shape of the heart and lungs, as well as any fluid buildup.
If a heart problem is diagnosed, the newborn will be referred to a cardiologist for further evaluation and treatment. It is important for parents to follow up regularly with their healthcare provider and cardiologist to ensure that their newborn receives the appropriate care and treatment.
It is important to note that not all heart problems in newborns cause symptoms, and some may be diagnosed later in life. Therefore, it is important for parents to be aware of the signs and symptoms of heart problems and to seek medical attention if they suspect that their newborn may have a heart problem.
Treatment and Management of Heart Conditions
When it comes to treating heart conditions in newborns, there are a variety of options available. Treatment will depend on the specific condition and its severity. In some cases, non-surgical interventions may be effective, while in other cases, surgical treatments may be necessary.
Non-Surgical Interventions
For some newborns with heart conditions, non-surgical interventions may be used to manage the condition. These interventions may include medications to help regulate heart function, oxygen therapy to improve blood flow and relieve symptoms, and careful monitoring to ensure that the condition does not worsen.
In cases where a newborn has a heart murmur, careful monitoring may be all that is needed. However, if the murmur is causing symptoms or is indicative of a more serious condition, further treatment may be necessary.
Surgical Treatments
In some cases, surgical treatments may be necessary to correct a heart condition in a newborn. Open-heart surgery may be required to repair structural abnormalities or to improve blood flow. In some cases, a heart transplant may be necessary to replace a damaged or malfunctioning heart.
While surgical treatments can be effective, they are not without risk. It is important to carefully weigh the risks and benefits of any surgical procedure before proceeding.
In addition to surgical treatments, newborns with heart conditions may require ongoing management and treatment for conditions such as heart failure, arrhythmias, and endocarditis. This may include medications to help regulate heart function and prevent complications.
It is important to work closely with a healthcare professional to determine the best course of treatment for a newborn with a heart condition. With proper treatment and management, many newborns with heart conditions are able to live healthy and fulfilling lives.
