Ventricular septal defect : Causes-Symptoms-Diagnosis-Treatment

 What is Ventricular septal defect (VSD)?

A bodily cavity congenital heart defect could be a hole within the wall that separates the lower chambers of your heart. Once this hole is massive enough, the amount of blood that is unseaworthy between the chambers will cause permanent injury to your heart and lungs and increase the danger of heart infections. Most VSDs don’t cause symptoms and shut on their own by age vi.

A bodily cavity congenital heart defect could be a condition wherever you are born with a hole within the wall between the 2 lower chambers of your heart. Typically shortened to VSD, this condition is that the most typical inherent (meaning you have got it once you are born) heart defect and infrequently happens aboard different varieties of heart issues or defects. A little VSD is sometimes minor and has few or no symptoms. However, a bigger hole might have to be repaired to avoid permanent injury and complications.

Your heart has four chambers. To pump blood with efficiency, the chambers have a lot of seals shut. A VSD could be a leak that disrupts that economical pumping ability.

What is Ventricular septal defect (VSD)?
Ventricular septal defect

Under traditional circumstances, the correct ventricle pumps gas-poor blood that simply arrives from your body out of your heart and into your lungs therefore the blood will acquire oxygen. The blood then returns to the guts, and its last stop within the heart is the ventricle that pumps oxygen-rich blood bent on your entire body.

A VSD could be a potential drawback as a result of it will act as a shunt (a connection) between the heart's 2 lower chambers, the ventricle and also the ventricle. As a result of the pressure within the ventricle is beyond the pressure within the ventricle, oxygen-rich blood mixes with oxygen-poor blood within the ventricle then goes to the lungs. That ends up in further blood within the lungs which may cause serious issues.

Almost all VSDs are a unit gift at birth. A VSD designation presumably happens throughout childhood, although adults can even receive this designation. However, this solely happens in 100 percent or less of cases. VSD is additionally slightly possible to happen in premature babies and babies with sure genetic conditions.

In terribly rare cases, a coronary failure will tear a hole between the ventricles and make a VSD. whereas this sort of VSD — generally known as bodily cavity body part rupture (VSR) — is technically an aspect impact, it's still a dangerous drawback that must be repaired.

VSD happens in a simple fraction of 1 Chronicles of all newborns. However, a VSD designation in adults is way less possible as a result of the defect closing on its own throughout childhood in nineteenth of cases.

VSDs in that area unit have an aspect impact of a coronary failure area unit extraordinarily rare, particularly due to trendy coronary failure treatment methods. Today, it happens in but 1 Chronicles of all heart attacks.

Medical terms

  • A cavity congenital heart defect (VSD), a hole within the heart, could be a common heart defect that is a gift at birth (congenital). The outlet (defect) happens within the wall (septum) that separates the guts's lower chambers (ventricles) and permits blood to pass from the left to the correct facet of the heart. The oxygen-rich blood then gets pumped-up back to the lungs rather than resolute the body, inflicting the guts to figure more durable.

  • A small cavity congenital heart defect might cause no issues, and plenty of little VSDs shut on their own. Medium or large VSDs may have surgical repair early in life to stop complications.

  •  Ventricular septal defect (VSD) is a condition in which there is an abnormal opening or hole in the wall between the right and left ventricles of your heart This usually happens before a baby is born Infants with VSD may have other problems with their heart such as holes between the chambers In adults VSD mostly affects males over age 40 who have a history of chest pain shortness of breath or fainting Depending on the location and size of the hole some people with VSD will not show signs or symptoms Those who do develop symptoms may have shortness of breath.

Types of Ventricular Septal Defects

A baby with a cavum congenital heart defect will have one or a lot of holes in several places of the septum. There are many names for these holes. Some common locations and names are area units (see figure).

There are four main varieties of VSD, that dissipate in their location and therefore the structure of the outlet (or holes). the categories of VSD are:

  1. Conoventricular Ventricular Septal Defect
    In general, this is a hole where portions of the ventricular septum should meet just below the pulmonary and aortic valves.

  2. Perimembranous Ventricular Septal Defect
    This is a hole in the upper section of the ventricular septum.

  3. Inlet Ventricular Septal Defect
    This is a hole within the septum with regards to wherever the blood enters the ventricles through the angular and mitral valves. This sort of bodily cavity congenital heart defect additionally may be a part of ANother heart defect referred to as an auriculoventricular congenital heart defect (AVSD).

  4. Muscular Ventricular Septal Defect
    This is a hole in the lower, muscular part of the ventricular septum and is the most common type of ventricular septal defect.

Symptoms Ventricular septal defect (VSD)

Signs and symptoms of serious heart defects often appear during the first few days, weeks or months of a child's life.

Ventricular septal defect (VSD) symptoms in a baby may include:

  • Poor eating, failure to thrive

  • Fast breathing or breathlessness

  • Easy tiring

You and your doctor may not notice signs of a ventricular septal defect at birth. If the defect is small, symptoms may not appear until later in childhood — if at all. Signs and symptoms vary depending on the size of the hole and other associated heart defects.

Your doctor may first suspect a heart defect during a regular checkup if he or she hears a murmur while listening to your baby's heart with a stethoscope. Sometimes a VSD can be detected by ultrasound before the baby is born.

Sometimes a VSD isn't detected until a person reaches adulthood. Symptoms and signs can include shortness of breath or a heart murmur your doctor hears when listening to your heart with a stethoscope.

When to see a doctor

Call your doctor if your baby or child:

  • Tires easily when eating or playing

  • Is not gaining weight

  • Becomes breathless when eating or crying

  • Breathes rapidly or is short of breath

Call your doctor if you develop:

  • Shortness of breath when you exert yourself or when you lie down

  • Rapid or irregular heartbeat

  • Fatigue or weakness

Causes Ventricular septal defect (VSD)

VSD, which is a gift at birth, does not presently have any notable causes. However, it will generally happen in conjunction with different heart defects, heart conditions or genetic disorders. Taking anti-seizure medications (sodium valproate and phenytoin) or drinking alcohol throughout gestation can also increase the chance of your kid developing a VSD. However, it'll take a lot of analysis to substantiate if these areas have definite causes.

The only notable reason behind VSD is once it happens as a rare aspect of a coronary failure.

Congenital heart defects arise from issues early within the heart's development, however there is usually no clear cause. genetic science and environmental factors could play a job. VSDs will occur alone or with different non heritable heart defects.

During vertebrate development, a bodily cavity congenital heart defect happens once the muscular wall separating the guts into left and right sides (septum) fails to make absolutely between the lower chambers of the guts (ventricles).

Normally, the proper aspect of the guts pumps blood to the lungs to urge oxygen; the left aspect pumps the oxygen-rich blood to the remainder of the body. A VSD permits aerated blood to combine with deoxygenated blood, inflicting exaggerated pressure level and exaggerated blood flow within the respiratory organ arteries. This leads to exaggerated work for the guts and lungs.

VSDs are also numerous sizes, and that they may be gifted in many locations within the wall between the ventricles. There is also one or a lot of VSD.

It's also doable to amass a VSD later in life, sometimes once a coronary failure or as a complication following sure heart procedures.

Risk factors Ventricular septal defect (VSD)

Ventricular body part defects might run in families and typically might occur with alternative genetic issues, like mongolians. If you have already got a baby with a heart defect, a genetic counselor will discuss the danger of your next kid having one.

Complications Ventricular septal defect

A small chamber congenital heart defect might ne'er cause any issues. Medium or giant defects will cause a variety of disabilities — from gentle to critical. Treatment will stop several complications.

Complications will include:

  • Heart failure. In a heart with a medium or giant VSD, the center works tougher and also the lungs have an excessive amount of blood tension to them. while not treating, failure will develop. 

  • Pulmonary hypertension. Increased blood flow to the lungs due to the VSD causes high blood pressure in the lung arteries (pulmonary hypertension), which can permanently damage them. This complication can cause reversal of blood flow through the hole (Eisenmenger syndrome).

  • Endocarditis. This heart infection is an uncommon complication.

  • Other heart problems. These include abnormal heart rhythms and valve problems.

Is VSD life threatening?

Ventricular septal defect also known as a hole in the heart is a condition in which there is an opening between the two lower chambers of your baby’s heart A Ventricular Septal Defect (VSD) can be present at birth or it may not become evident until later in childhood or adult life Approximately 10% of all congenital heart defects are VSDs This type of a defect occurs when developing baby's heart tissue divides incorrectly and leaves a small hole between the ventricles.

How is ASD and VSD corrected?

The most common surgery for ASD is called a shunt procedure During the procedure a neurosurgeon places a small tube into the ventricle (the fluid-filled cavity inside your child's brain) and connects it to another part of your child's body where there is less pressure (such as the abdominal cavity) The flow of excess fluid out of your child's brain can help prevent further enlargement and build-up of fluid In some cases a VSD will be closed using open heart surgery.

When is surgery needed for VSD?

Ventricular septal defect (VSD) is the most common congenital heart disease accounting for approximately 25% of all congenital heart defects in children About 80% of VSDs close on their own by adulthood However when a ventricular septal defect remains open after the first year of life it needs repair and treatment or else risk complications Surgery may be necessary for transposition of the great vessels in which blood bypasses from one side to the other causing serious complications if not corrected.

Does VSD require open heart surgery?

No The earlier a VSD is identified the better but treatment does not require open heart surgery Once it has been diagnosed the doctor needs to identify how big the defect is and decide whether or not you will need surgery to close it up.

What is the success rate of VSD surgery?

Success rates for ventricular septal defect surgery vary according to the size of the defect whether it is a simple or complex procedure and how many previous attempts at closure have been made Overall about 75 percent of patients are alive 10 years after surgery with no recurrence of the VSD Other good news is that in most cases there has been little or no pulmonary hypertension and even greater good news most patients experience improved athletic performance after their surgeries.

How does VSD cause death?

Ventricular septal defect (VSD) causes death when the pressure within the heart increases and pushes blood into the lungs This shunting of blood leads to congestive heart failure a life-threatening condition that can further cause fluid build-up in the lungs and other organs difficulty breathing or breathlessness during rest coughing up of blood collapse or rarely stroke.

Does VSD get bigger?

Multiple studies have reached conflicting conclusions about the potential progression into adulthood of VSD in children Some believe that it is a benign lesion in childhood that gradually closes as the child grows while others believe that it remains present throughout life Studies have also suggested that some type of physical activity can cause the defect to worsen.

Prevention Ventricular septal defect

In most cases, you cannot do something to forestall having a baby with a bodily cavity congenital heart defect. However, it is important to try and do everything attainable to possess a healthy physiological condition. Here square measure the basics:

  • Get early prenatal care, even before you're pregnant. Talk to your doctor before you get pregnant concerning your health and discuss any lifestyle changes that your doctor might suggest for a healthy gestation. Also, make sure you consult with your doctor concerning any medications you take. 

  • Eat a balanced diet. Include a vitamin supplement that contains folic acid.

  • Exercise regularly. Work with your doctor to develop an exercise plan that's right for you.

  • Avoid risks. These include harmful substances such as alcohol, tobacco and illegal drugs.

  • Avoid infections. Be sure you are up thus far on all of your vaccinations before turning into pregnant. sure varieties of infections are often harmful to a developing fetus. 

  • Keep diabetes under control. If you have got a polygenic disease, work together with your doctor to make sure it's well controlled before obtaining a pregnancy.
    If you have a case history of heart defects or alternative genetic disorders, contemplate talking with a genetic counselor before obtaining a pregnancy. 

Diagnosis Ventricular septal defect (VSD)

A chamber congenital heart defect sometimes is diagnosed when a baby is born.

The size of the chamber congenital heart defect can influence what symptoms, if any, are a gift, and whether or not a doctor hears a cardiac murmur throughout a physical examination. Signs of a chamber congenital heart defect could be a gift at birth or won't seem well until birth. If the outlet is tiny, it always can shut on its own and therefore the baby won't show any signs of the defect.

Ventricular body part defects (VSDs) typically cause a cardiac murmur that your doctor will hear employing a medical instrument. If your doctor hears a cardiac murmur or finds alternative signs or symptoms of a heart defect, he or she might order many tests including:

  • Echocardiogram. In this check, sound waves turn out a video image of the center. Doctors could use this check to diagnose a cavity congenital heart defect and verify its size, location and severity. it should even be accustomed to see if there are other heart issues. diagnostic procedure may be used on a vertebrate (fetal echocardiography). 

  • Electrocardiogram (ECG). This test records the electrical activity of the heart through electrodes attached to the skin and helps diagnose heart defects or rhythm problems.

  • Chest X-ray. An X-ray image helps the doctor view the heart and lungs to see if the heart is enlarged and if the lungs have extra fluid.

  • Cardiac catheterization. In this take a look at, a thin, versatile tube (catheter) is inserted into a vessel at the groin or arm and radio-controlled through the blood vessels into the guts. Through internal organ catheterization, doctors will diagnose inherent heart defects and verify the operate of the guts valves and chambers 

  • Pulse oximetry. A small clip on the fingertip measures the amount of oxygen in the blood.

Treatment Ventricular septal defect (VSD)

Treatments for a cavum congenital heart defect depend upon the scale of the outlet and therefore the issues it would cause. Several cavum septum defects are tiny and shut on their own; if the outlet is tiny and not inflicting any symptoms, the doctor can check the babe frequently to confirm there aren't any signs of heart condition which the outlet closes on its own. If the outlet doesn't shut on its own or if it's massive, more actions may have to be taken.

Depending on the scale of the outlet, symptoms, and general health of the kid, the doctor may advocate either internal organ catheterization or heart surgery to shut the outlet and restore traditional blood flow. After surgery, the doctor can get wind of regular follow-up visits to ensure that the cavum congenital heart defect remains closed. Most kids at the UN agency have a cavum congenital heart defect that closes (either on its own or with surgery) to live healthy lives.

Many babies born with atiny low cavum congenital heart defect (VSD) will not like surgery to shut the outlet. when birth, your doctor might want to watch your baby and treat symptoms whereas waiting to ascertain if the defect closes on its own.

Babies UN agencies would like surgical repair typically to have the procedure in their initial year. Young and adult UN agencies have a medium or massive cavum congenital heart defect or one that is inflicting vital symptoms might have surgery to shut the defect.

Some smaller cavum septum defects are closed surgically to stop complications associated with their locations, like harm to heart valves. Many of us with tiny VSDs have productive lives with few connected issues.

Babies UN agency have massive VSDs or UN agency tire simply throughout feeding might have further nutrition to assist them grow. Some babies could need medication to assist treat heart conditions.


Medications for cavity congenital heart defect rely on the severity of cardiomyopathy symptoms. The goal of medication is to decrease the number of fluid in circulation and within the lungs. Medications known as diuretics, like Lasix (Lasix), scale back what proportion blood should be tense.

Surgeries or other procedures

Surgical treatment for bodily cavity congenital heart defects involves plugging or mending the abnormal gap between the ventricles. If you or your kid has surgery to repair a bodily cavity defect, contemplate having surgery performed by surgeons and cardiologists with coaching and experience in conducting these procedures.

Procedures to treat VSD might include:

  • Surgical repair. This procedure of selection in most cases sometimes involves heart surgery beneath anesthesia. The surgery needs a pump Associate in Nursing an incision within the chest. The doctor uses a patch or stitches to shut the outlet. 

  • Catheter procedure. Closing a cavum congenital heart defect throughout catheterization does not need to gap the chest. Rather, the doctor inserts a skinny tube (catheter) into a vessel within the groin and guides it to the guts. The doctor then uses a specially sized mesh device to shut the opening.
    After repair, your doctor can schedule regular medical follow-up to confirm that the cavum congenital heart defect remains closed and to see for signs of complications. betting on the dimensions of the defect and also the presence of alternative issues, your doctor can tell you ways oftentimes you or your kid can get to be seen. 

Lifestyle and home remedies

After your bodily cavity congenital heart defect (VSD) is repaired, you or your kid would like follow-up care throughout life for doctors to watch your condition and check for any signs of complications.

Your doctor might advise that you just or your kid have regular follow-up appointments with a doctor WHO focuses on non heritable cardiovascular disease. In follow-up appointments, your doctor might value you or your kid and order imaging tests to watch your or your child's condition.

Here ar a number of tips for managing your or your child's condition:

  • Consider pregnancy carefully. Before becoming pregnant, ask a doctor trained in heart conditions (cardiologist) to see if you'll be able to endure physiological conditions safely. This is often particularly vital if you are taking medications. It is also vital to check each AN accoucheur and a specialist throughout physiological conditions.
    Having a repaired VSD while not having complications or having a tiny low defect does not cause an oversized extra physiological condition risk. However, having AN unrepaired, larger defect; heart failure; respiratory organ hypertension; abnormal heart rhythms; or alternative heart defects poses a high risk to each mother and vertebrate.
    Doctors powerfully advise ladies with Eisenmenger syndrome to not become pregnant attributable to the high risk of complications. 

  • Prevent endocarditis. You or your kid sometimes will not have to be compelled to take Associate in Nursing Antibiotics before certain dental procedures to stop an infection of the heart's inner lining (endocarditis).
    However, your doctor might suggest antibiotics if you've got had previous carditis, a heart valve replacement, if you've got had a recent VSD repair with artificial material, if you continue to have leaks through the VSD, if the repaired VSD is next to a defect that is been repaired with artificial material, or if you've got an oversized chamber congenital heart defect that is inflicting low element levels.
    For most individuals with a chamber congenital heart defect, smart oral hygiene and regular dental checkups will stop carditis. 

  • Follow exercise recommendations. Your doctor will advise you concerning that activities are unit safe for you or your kid. If some activities cause special dangers, encourage your kid to interact in different, safer activities. confine mind that several kids with VSDs will lead healthy, totally active, productive lives.
    Children with tiny defects or a repaired hole within the heart can typically have few or no restrictions on activity or exercise. kids whose hearts do not pump as unremarkably can ought to follow some limits. a toddler with irreversible pulmonic cardiovascular disease (Eisenmenger syndrome) has the best range of restrictions. 

Coping and support

Consider change of integrity a support cluster for families of kids born with heart defects. Support teams will facilitate elders, families and caregivers, notice answers, connect with alternative families, and share their hopes and issues with others facing similar challenges.

Preparing for your appointment

If you or your kid develops signs and symptoms common to cavity congenital heart defects, make a decision with your doctor. When attending the initial examination, it's possible that the doctor can refer you or your kid to a doctor UN agency focuses on the identification and treatment of heart conditions (cardiologist).

Here's some info to assist you steel yourself for your appointment.

What you can do

  • Write down signs and symptoms you or your child has had and for how long.

  • Write down key medical information, including different health issues and also the names of any medications you or your kid is taking, or procedures you or your kid have had (including reports). 

  • Find a family member or friend who can come with you to the appointment, if possible. Someone who accompanies you can help remember what the doctor says.

  • Write down the questions to ask your doctor.

Questions to ask the doctor at the initial appointment include:

  • What is likely causing these symptoms?

  • Are there other possible causes?

  • What tests are needed?

  • Should a specialist be consulted?

Questions to ask if you are referred to a cardiologist include:

  • How large is the defect?

  • What is the risk of complications from this condition?

  • What treatment do you recommend?

  • How often should we schedule follow-up exams and tests?

  • What signs and symptoms should I watch for at home?

  • What is the long-term outlook for this condition?

  • Do you recommend dietary or activity restrictions?

Don't hesitate to ask other questions.

What to expect from your doctor

Your doctor may ask a number of questions, including:

If you are the person affected:

  • What are the symptoms?

  • When did the symptoms begin?

  • Have the symptoms gotten worse over time?

  • Are you aware of heart problems in your family?

  • Are you being treated, or have you recently been treated for other health conditions?

  • Are you planning to become pregnant?

If your baby or child is affected:

  • Does your child tire easily while eating or playing?

  • Is your child gaining weight?

  • Does your child breathe rapidly or run out of breath when eating or crying?

  • Has your child been diagnosed with other medical conditions?

General summary

  1. Patients with tetralogy of Fallot (TOF) unrepaired ventricular septal defects (VSD) are at high risk of pulmonary vascular complications and death within the first 10 years after birth The occurrence of a VSD in patients with TOF is associated with significant morbidity which can lead to right heart failure recurrent infections and early death Palliative care should be considered as part of the standard treatment for these patients by preventing progression of symptoms and avoiding invasive or aggressive interventions that cause additional morbidity or mortality Given their life expectancy is limited without surgery palliative management may appeal to.
