MUGA shows mild right ventricle hypokinesis

I had my third MUGA on Friday and the report shows 63% LVEF with mild right ventricle hypokinesis. My oncologist didn't mention the RV hypokinesis. I requested a copy of the report in the chemo department, which is when I saw this new findings--unfortunately, after I had completed herceptin infusion. This new finding has me concerned, and I can't find any satisfactory explanation of its meaning on the internet. Any information would be helpful.
