Infant Heart Murmur

I have a 15 month old daughter. Very active, very healthy, growing and developing just fine. A slight heart murmer was detected 12 months ago, and the doctor's advice was to come back in 12 months for evaluation. The murmur is more pronounced now, and has been called a "flow murmur". We have an appointment made at the Childrens Heart Clinic. What can I expect? What should I ask? What is a "flow murmur"? Thanks!

A flow murmur typically is a harmless sound caused by the normal flow of blood. The importance lies in differentiating it from the more serious causes of a heart murmur. The doctors at the heart clinic wil be familiar with this common situation. Just ask them what the murmur is due to and whether it is anything that requires further testing.
