title: Ask the doctor.  At 78 years old, I am in pretty good shape.  A couple of years ago, an echocardiogram showed a small leak in my mitral valve.  A year later, a follow-up test showed some leakage in my tricuspid valve.  The valves aren't causing me any problems right now, but how wil I know if they need to be repaired?  I like to exercise, but don't want to make these valve problems worse.  Is it okay for me to walk on a treadmill at a speed of 3 to 4 miles an hour or lift light weights?
