What is the symptoms of having a ventricular septal defect?

Depends on size: Many vsds are mild and close on their own. Some are quite big and need surgery to repair them. Symptoms can be nothing to fatigue from shunting blood the wrong way. There is usually a loud heart murmur but that does not cause symptoms alone. A cardiologist can provide more information for the specific patient.

Depends on age: Symptoms depend on age and the size of the vsd. Small vsds usually are asymptomatic except for a murmur heard on exam. Moderate to large vsds usually present with respiratory distress, sweating, poor feeding and poor weight gain in infants (1-2 mo old). Also exercise intolerance in older children.
