A ventricular septal defect (VSD) is a hole in the wall between the heart's two lower chambers. It can change the way blood flows in the heart and make the heart work harder. This can make the right side of the heart larger and cause problems in the lungs.
Most VSDs will close on their own. If there are no signs of heart failure, the best treatment may be to wait. Regular check-ups will make sure complications do not arise.
Larger holes put an extra workload on the heart. They also cause higher blood pressure in the arteries of the lungs. These problems can lead to
and lung damage. Activities will be limited. These holes will need to be treated.
A VSD is treated with one or more of these:
Medicines can delay the need for surgery for severe VSD. They can also ease symptoms of heart failure.
Medicine may be used to:
Relax the blood vessels
Help the heart pump more effectively
Lessen the workload on the heart
Remove excess fluid from the body
Lower blood pressure
Children who are not gaining weight may need extra nutrition. High-calorie formula, breast milk supplements, and tube feedings may be needed.
Surgery is needed to fix large VSDs that cause problems or that have not closed by 1 year of age. It will lower the risk of other heart-related problems in the future. The hole is fixed with a patch. Over time, the heart lining will grow over it. Options are:
Percutaneous procedure: A tube is inserted into a blood vessel in the thigh and passed up to the heart. A patch is used to seal the hole in the heart.
Open heart surgery: A large incision is made in the chest and a patch is used to close the hole.
Long Term Care
Lifetime monitoring will be needed. Problems can happen as a child gets older. Monitoring can help find problems before they happen. This may involve:
A yearly exam with a heart specialist
Regular tests of heart function
Changes to the child's treatment plan
There are no known methods to prevent this health problem.
