Is 3 leaky heart valves something to be afraid of? no congestive heart failure and being treated with a ace inhibitor and diuretic.

All relative : Depends on degree of leakiness. If your doc didn't make a big deal of it then doesn't seem you need to be monitored. Sometimes it does require repeat echocardiograms in the future though.

Depends - ? severity: depends upon the severity, which ones, possible causes; often things need to be followed, your doctor should be able to give you good advice....
