Heart blow: Heart valve disease warning

Article by Dr. Nguyen Van Duong, Cardiovascular Center – Share99 Central Park International Health Hub

The blow in the heart is the sound that is heard during the functioning of the heart, which is made up of the movement of blood flow through the heart. This blow can be heard using a medical listening tube. A normal heartbeat will make 2 sounds like: "boom – pirate", which is the sound of the heart valve closing.

1. Is the heart blow dangerous?

The blow in the heart can appear as soon as it is born(congenital heart disease) or develop after a while(heart valve disease). Not all blows in the heart to be pathology, however it can be pre-million of a cardiovascular pathology.

Most often, the blow in the heart is harmless and does not require treatment. But some special heart blows need to monitor and do more intensive tests to assess the cause of the blow and treat it.

2. Symptoms of heart blows

If you have an abnormal blow in theheart , it is possible that it has no special symptoms. Your doctor may detect a blow in your heart with a heart lens when you have a regular general health check-up. However, if you or your child has the following symptoms, you may be suffering from cardiovascular problems, it is necessary to consult with your doctor:

  • Pale skin, especially lips and fingertips
  • Edema or sudden weight gain
  • Shortness of breath
  • Chronic cough
  • Hepatic enlarged (usually causing lowering of the right flank)
  • Floating cervical veins
  • Poor eating or no normal development (with babies)
  • Sweating with mild exertion
  • Chest pain
  • Dizziness
  • Fainting

3. Causes of blows in the heart

There are 2 types of blows in the heart: normal and abnormal. A person with a normal heart blow has a healthy heart. This type is common in babies and young children.

An abnormal heart blow is more serious. In children, abnormal heart blows are often the cause of congenital heart disease. In adults, it is often the cause of heart valve pathology.

Normal heart blow:

A normal heart blow occurs when the blood flow through the heart is faster than usual. This condition is common in:

  • Exertion
  • pregnant
  • High fever
  • anemia
  • Armor
  • Can be seen in adolescence

Normal heart blows will disappear after a while, however to determine your or your child's heart blow is normal it is necessary to consult a cardiologist.

Abnormal heart blows:

The most common cause of abnormal heart blows in children is abnormal heart structure of the child at birth (congenital heart defects)

Congenital heart defects are the cause of heart blows, including:

  • Abnormal holes in the heart: commonly known by the name of atrial fibrillation or atrial fibrillation … Abnormal vents may not be serious, depending on its location and size.
  • Congenital heart valve abnormalities : appear at birth but sometimes do not detect until adulthood. Common are diseases that cause heart valve stenosis or open heart valves.

Other causes of abnormalheart attacks are changes in the structure of the heart valves due to infection or autoimitted pathology. This is common in adults or older children, including:


A media connection produces an abnormal heart blow
  • Cardicardiosis : The valve leaves will thicken and calcified, such as mitral or aortic valves. Then the opening of the heart valve will narrow, making the amount of blood through the valve in your heart more difficult to cause a blow in the heart.
  • Endocarditis : Infection occurs in your heart and in the valve leaves, usually caused by bacterial infections from other areas of the body (usually the mouth) that follow the bloodstream and cause disease in your heart. Without timely treatment, endocarditis will destroy your heart valve leaves and will cause abnormal heart valve diseases that create a blow in the heart.
  • Low posterior heart valves : Although quite rare in this day and age, post-low heart valves are serious heart valve damage caused by non-treatable pharyngitis. It will cause permanent damage to the heart valve (usually mitral and aortic valves) and must have heart valve replacement surgery when in place.

4. Risk factors

Risk factors that increase the likelihood of a blow in the child's heart include:

  • Getting sick during pregnancy :Some pregnancy-infected diseases such as urinary inaction or rubella infection increase the risk of congenital heart defects and cause heart blows
  • Inappropriate use of the drug during pregnancy: Use of certain high-risk drugs, alcohol, drugs harmful to fetal development and causes of heart blows.

5. When to see a doctor?

Most of the blows in the heart are not serious, but if you think you or your child have a blow in the heart, it is advisable to consult a cardiologist. Your doctor will correctly inform you if the heart blow is normal or abnormal, and will give you advice on whether to do more intensive tests or further treatment or not.
