I have just been told that both my R ventricle and L atrium are enlarged. What does this mean?r=124507?

I have not seen a cardiologist, but they gave me this info based on the echo I had. Also, I had the Berkeley done and it showed an elevated cysteine level and KIF6 Genotype: 719Arg/Arg zygous carrier of the KIF6 719Arg allele. My hematocrit was low, although they never gave me the numbers on that one. Should I be concerned? Should I see a cardiologist?
