my 23 yr old son was told he had a murmur so they did an echo which showed right side dilation. His doctor is scheduling an appt with a cardiologist for him. What can this mean?

Murmurs can occur due to multiple causes.
The most common cause identified at this age is likely to be a Biuspid Pulmonary Valve or septal defects.

Most of these defects cause enlargement of the right side of the heart. Its a compensatory mechanism.

If a dilation is found without any underlying valvular or septal defect, then this means there could be increase in the Pulmonary pressure i.e the right sided pressures.

A detailed cardiologic examination and evaluation can pinpoint the cause.

Be reassured as he does not have any symptoms.

Hope this answers your query.
Please get back if you need any further information.
