Validation of nine differentially expressed miRNAs in the atrial myocardial tissue of patients with CHD after CBP (n = 11) compared to before CPB (n = 11) as determined by RT-qPCR (P < 0.05). Mean ΔCt before CPB and after CPB (Lower ΔCt, higher expression level). RNAU6B as an endogenous control for normalization, paired-two-tailed t-tests and ±standard deviation (STDV) were used to evaluate differences in expression
