Ventricular Septal Defect
|
|
- The heart has two ventricles -- a left and a right. The right ventricle pumps blood returning from the body to the lungs. The left ventricle takes the blood returning from the lungs and pumps it out to the rest of the body. There is normally a septum, or wall, separating the left ventricle from the right.
- Sometimes, a hole may develop at or after birth in this wall. The symptoms and treatment of this disease depend on the size of the hole. Often, this problem is detected early and treated in childhood.
|
|
- If the hole is small, the patient may never have any symptoms or may only develop symptoms as an adult.
- If the hole is large, then it can potentially cause heart failure, poor oxygenation of the blood, bluish discoloration of the fingers and toes, high pressure in the lungs, shortness of breath, swelling of the legs, liver congestion, fatigue, poor weight gain in children, and difficulty breathing when lying flat at night.
- On examination, the doctor may detect a Heart Murmur or may see evidence of heart failure.
|
|
- Ventricular septal defects are most often due to the failure of the wall separating the left and right ventricle to close fully during a baby's development in the uterus.
- Rarely, infections of the heart or Injury to the heart (e.g., heart attack) can be the cause of this problem.
|
|
- An electrocardiogram (EKG) may show enlarged heart chambers.
- Chest X-rays may show an enlarged heart and evidence of heart failure.
- An echocardiogram (an ultrasound of the heart) is an accurate test to expose the heart defect.
- A color flow Doppler study can show (in color) the jet flow across the defect.
- Sometimes an MRI (magnetic resonance Image) of the heart may also show the hole.
- The best test is a cardiac catheterization (in which dye is injected into the heart and the hole is seen with X-rays). However, this is not necessary if the other tests can see the hole adequately.
|
|
- If the ventricular septal defect is
small and the patient does not have any symptoms, then no
treatment is needed. The patient's life expectancy
should be normal.
- If the defect is large, then without
treatment, the patient often develops heart failure early in
life and often dies by age 40.
- Many times these defects heal by
themselves and no surgery is needed.
- However, if the hole has not sealed
up by the time the patient is 9 to 12 years old, then
surgery to close it will be needed -- to prevent later
complications.
- In some cases, a child with this
condition may develop severe symptoms very early, requiring
surgery to be done much sooner. If surgery is delayed
too long, the damage may be permanent.
- In some cases, surgery is possible
without opening up the chest.
- Whether and when surgery should be
done needs to be discussed with the doctor. Also, he
will explain the details of the surgery, including dangers
and prognosis.
- In cases where congestive heart failure or other
symptoms develop, heart medications (e.g., Nitoglycerin, ACE
inhibitors, Hydralazine, diuretics, Digoxin, and others) may
be used to control symptoms or until surgery is
performed.
|
|
- Patients with a ventricular septal defect are at a much
higher risk for developing endocarditis (infections of the
heart). This condition can be life threatening, but it can
also be prevented. Therefore, it is absolutely crucial that
antibiotics be taken prior to any surgery, including tooth
extractions.
- If your child has a ventricular
septal defect, you must tell his/her doctor and dentist so
that they can give the appropriate antibiotics before
surgery.
