The atria of the heart merely need to allow blood to flow into the ventricle, and therefore aren't very muscular. 
The ventricles of the heart need to actually pump blood to the rest of the body, whether to the lungs or the the rest of the body. 
        
                    
             
        
        
        
 If siRNA against a starch-branching enzyme was transmitted to humans, then it may affect the expression of glycogen-branching enzymes. RNAi inhibits gene expression.
Glycogen-branching enzymes are similar to starch-branching enzymes because glycogen bonds are similar to those observed between amylopectin.
The RNA interference (RNAi) pathway is an evolutionarily conserved mechanism used in molecular biology laboratories to inhibit the expression of target genes.
In the RNAi technique, a regulatory non-coding RNA called small interfering RNA (siRNA) that exhibits sequence complementary to the target gene sequence is used to inhibit and/or block the translation of the target mRNA (in this case, starch/glycogen-branching mRNA coding enzyme).
