MV and Tricuspid insufficiency

I am 45-years-old. Female. I have a four year history of arrythmia - PAC & PVC.  No MVP showed up four years ago on an echo, but due to symptoms (irregular heartbeat), it was diagnosed (I never saw report, so it is possible that a trace insufficiency was also on there).  Took antibiotics prior to dentist since.  New MD wondered if meds were necessary since she didn't hear a murmur and sent me to a different cardiologist for a second echocardiogam.  Test came back saying I didn't need antibiotics for dental procedures, the MD said it showed a healthy heart. But the copy for me to hand carry to the dentis also said that a trace mitral insufficiency and a trace tricuspid insufficiency was found.  I did google research and got concerned when I found a link showing that tricuspid insufficiency is linked to pulmonary hypertension.  I have a sibling with PH.  Most of the sites I visited didn't really clarify a trace from acute in the symptoms/prognosis.  
I stumbled on to this site and was hoping to use the forum with an MD, but one wasn't available, so I thought I would see what others had experienced.  Should I be concerned.  On this site I saw people answer that almost every echo shows a trace of MV regugitation, but what about the tricuspid insufficiency???

Trace tricuspid regurge showing is really common too. Words like "Trace" and "Trivial" are pretty clear clues to not worry about it.  

If your echocardiogram indicated pulmonary HTN it should have been in the summary report. If it had your doctor would have brought you in for it.

You don't have to take antibiotics and that's a good thing. They are a hassle and can cause many people ( I get stomach upset) side effects.

I wish they'd tell me I didn't need them. I tried to get them to tell me that, believe me. I even asked the CC doctor here if I needed them and, unfortunately, he said yes.

Thanks for your reply.  I will be able to reach my MD tomorrow and get more information.  
I did find the article on the web re: the newer thoughts that antibiotics are not needed as frequently as prescribed.  This fits with my experience talking to others: It appears to be a regional thing with all MD's in one area agreeing while another state/city they all feel the opposite!

"The guidelines, published in Circulation: Journal of the American Heart Association, are based on a growing body of scientific evidence weighing the effectiveness of antibiotics against possible risks. The updated recommendations say that only people who are at the greatest risk of bad outcomes from infective endocarditis (IE) -- an infection of the heart's inner lining or the heart valves -- should receive short-term preventive antibiotics before common, routine dental procedures. This includes people with artificial heart valves, a history of previous endocarditis, certain serious congenital heart conditions, and heart transplants patients who develop a problem with a heart valve.
