What is a Ventricular septal defect (VSD)?

A hole in the heart is called a ventricular septal defect (VSD). Congenital heart defects are frequent heart conditions that exist from birth. The hole is located in the wall dividing the ventricles, the heart's lower chambers.

A ventricular septal defect (VSD) alters the flow of blood through the heart and lungs. Instead of leaving the body, oxygen-rich blood is sent back to the lungs. Blood that is low in oxygen combines with blood that is high in oxygen. Due to these alterations, the heart may have to work harder to pump blood, which could lead to increased blood pressure in the lungs.

What is the Importance of Timely Treatment?

Timely diagnosis of a Ventricular Septal Defect (VSD) is essential for avoiding complications and ensuring optimal heart function. Due to the increased burden on the heart and irregular blood flow, VSD can cause complications like respiratory infections, growth problems, pulmonary hypertension, and heart failure if treatment is not received.

Early intervention, often through surgery or catheter-based techniques, can significantly enhance the patient's quality of life, close the heart hole, and prevent long-term harm. On time, treating VSD also lowers the chance of serious side effects, including arrhythmias and stroke, promoting normal cardiac development and enabling the child to live a healthy life.

What are the Common Symptoms of a Ventricular septal defect (VSD)?

Symptoms of VSD in infants can include:

  • Unhealthy eating
  • Physical growth is either slow or nonexistent (failure to flourish).
  • Breathlessness or rapid breathing
  • Simple exhaustion
  • Using a stethoscope to listen to the heart produces a whooshing sound (heart murmur).

Adults with a ventricular septal defect can show the following symptoms:

  • Breathlessness, particularly with physical activity
  • Using a stethoscope to listen to the heart produces a whooshing sound (heart murmur).

Types of Ventricular septal defect (VSD)

The location of the hole (or holes) and structure vary across the four primary forms of VSD. The types of VSD are:

  • Membranous: About 80% of instances with VSD are of this type, which is the most prevalent. These VSDS occur in the upper portion of the wall between the ventricles.
  • Muscular: This causes approximately 20% of baby VSDs, and the defect often consists of multiple holes.
  • Inlet: This hole appears directly beneath the left ventricle's mitral valve and the right ventricle's tricuspid valve.
  • Outlet (conoventricular): This type of VSD connects the two chambers by making a hole in the right ventricle just before the pulmonary valve and in the left ventricle just before the aortic valve.

Causes, Risk Factors and Complications of Ventricular Septal Defect (VSD)

Causes

  • During pregnancy, a condition known as a ventricular septal defect (VSD) develops in the growing baby's heart. The incomplete formation of the muscle wall that divides the heart into the left and right halves leaves one or more holes, which may vary in size.
  • Frequently, the cause is unclear. Environmental and genetic factors might be involved. VSDS can happen on their own or in combination with other congenital cardiac conditions. Ventricular septal defects can, in rare cases, develop later in life following a heart attack or specific cardiac surgeries.

Risk Factors

Ventricular septal defect risk factors include:

  • Premature birth
  • Down syndrome and other hereditary disorders
  • Family history of congenital heart disorders or heart issues that exist from birth

Other cardiac issues in a newborn with a ventricular septal defect include:

  • Defect of the atrial septum
  • Coarctation of the aorta
  • Syndrome of double outlets
  • Arteriosus patent ductus
  • Tetralogy of Fallot

A genetic counsellor can talk about the likelihood that your next child will have a congenital heart issue if you already have one.

Complications

Ventricular septal defects can raise the likelihood of other issues if left untreated, such as

  • Heart failure
  • Elevated pulmonary blood pressure, also known as pulmonary hypertension
  • Heart rhythm irregularities, or arrhythmias
  • A stroke

Latest Research and Technologies in the Treatment of Ventricular Septal Defect (VSD) in Singapore

  • The utilisation of minimally invasive procedures, such as transcatheter device closure and periventricular device closure, has improved the treatment of Ventricular Septal Defect (VSD) in Singapore. These techniques shorten hospital stays and healing times.
  • Furthermore, creating sophisticated occlusion tools enables safer and more efficient VSD treatments, enhancing patient outcomes.

Ventricular septal defect (VSD) Prevention Tips

Ventricular septal defect (VSD) might not be preventable because the cause is unknown. However, receiving quality prenatal care is essential. Make an appointment with your healthcare professional and take the following actions if you have a VSD and intend to get pregnant:

  • Even before you get pregnant, get early prenatal care.
  • Take folic acid-containing multivitamins.
  • Avoid alcoholic beverages while pregnant.
  • Avoid using illegal substances and smoking.
  • Obtain the appropriate immunisations.
  • Manage your diabetes.
  • Before taking any medications, speak with your doctor because some can result in birth abnormalities.

Treatment options for Ventricular septal defect (VSD)

VSD closure repair: With the help of the catheterisation process without requiring open heart surgery, specific ventricular septal abnormalities can be fixed with thin, flexible tubes called catheters.


Cost Start From USD 20000 - USD 28000Explore Options

Open-heart surgery: This is the recommended correction method for most ventricular septal defects. The opening between the lower heart chambers is sealed by a surgeon using stitches or a patch. A chest incision and a heart-lung machine are necessary for this kind of VSD surgery.

  • Prenatal Diagnosis:
    • Pregnancy ultrasound: However, ventricular septal defects (VSDs) are identified shortly after birth. Pregnancy ultrasounds can occasionally identify ventricular septal defects (VSD) before delivery.
  • Postnatal Diagnosis:
    • Echocardiogram: This test creates images of the heart using sound waves.
    • Chest X-ray: An X-ray of your baby's chest can reveal the size and form of their heart and lungs.
    • Electrocardiogram (EKG): An EKG measures a heartbeat's electrical activity
    • Cardiac catheterisation: This test aids in diagnosing or managing specific cardiac disorders. It could be used to schedule surgery.
    • Oxygen level measurement: The blood's oxygen content is rapidly measured by a tiny pulse oximetry test applied to a finger or toe.
    • Cardiac magnetic resonance imaging (MRI) scan: Radio waves and magnetic fields are utilised to produce detailed images of the heart. A medical professional may order this test if additional information is required following an echocardiography.
    • Computerised tomography (CT) scan: A series of X-rays show the heart in depth. If an echocardiography didn't yield enough information, it might be done.

The rehabilitation goals for a Ventricular Septal Defect (VSD) are to improve the patient's overall health and support their recovery following surgery. Essential choices for rehabilitation include:

  • Physical Therapy: Particularly for children or adults recovering from open heart surgery, post-surgical physical therapy aids in the restoration of strength and movement. It comprises activities to increase endurance and cardiovascular fitness.
  • Cardiac Rehabilitation: Programs for cardiac rehabilitation may be recommended for elderly individuals and young adults. It is to help people resume their regular activities and avoid difficulties.
  • Breathing Exercises: If the VSD has caused or contributed to respiratory problems, breathing exercises can improve oxygen levels and lung function.

Medication can treat symptoms of a VSD before surgery or if it closes on its own. Common medications include diuretics, which increase kidney fluid removal, and medications for heart failure, which control the strength of the heartbeat.

Frequently Asked Questions

Recovery from a VSD repair depends on the method used. Recovery periods from transcatheter procedures are shorter. Recovery periods following surgeries are lengthier and expressed in weeks or months. Typically, VSD symptoms subside or resolve following surgery or transcatheter repair.

Treatment for Ventricular Septal Defect (VSD) has a success rate in Singapore. While device closures have a 96% success rate, spontaneous closure happens in 55% of newborns. Although results vary depending on personal characteristics such as age, the severity of the illness, and general health, surgical procedures also show promising results.

The type of treatment determines the length of the healing period. Whereas overall care guarantees a quicker recovery, recovery from open heart surgery may take several weeks, whereas minimally invasive operations can take one to two weeks.

Prevention is typically impossible for VSD because its causes are not yet identified. However, staying away from alcohol and other medications that prevent seizures while pregnant can reduce the risk.

By the time a person is six years old, approximately 90% of VSDs will close independently. By the age of 20, most of the 10% of VSDs will close. After that, however, a VSD is unlikely to collapse on its own. Unless they have surgery to fix it, an adult with VSD will have it for the rest of their life.

Life expectancy with a Ventricular Septal Defect (VSD) primarily depends on the size of the defect, the timing of treatment, and whether complications develop. The life expectancy of people with modest to moderate VSDs is usually normal, especially if they receive early treatment.

However, life expectancy may be shortened by severe VSDs that go untreated or those that have consequences such as cardiac failure or pulmonary hypertension. Most persons with VSD can lead healthy lives if they receive timely surgery.

Not always. While bigger or symptomatic abnormalities frequently require surgical intervention to prevent consequences, including heart failure or pulmonary hypertension, minor or moderate VSDs might not need surgery.

Although unlikely, a VSD may return following surgery, especially if the defect is significant or the repair process is complicated. Ongoing monitoring is required for any remaining holes or associated cardiac issues.

A large VSD might result in severe symptoms like heart failure, exhaustion, or growth issues because of the increased blood flow to the lungs, but a tiny VSD typically causes few or no symptoms and may go away on its own.
