Abstract: This study explored the diagnostic value of Tissue Doppler Imaging (TDI) combined with serum microRNA-34a (miR-34a) in the diagnosis of children congenital heart disease (CHD) complicated with pulmonary arterial hypertension (PAH). According to the occurrence of PAH, all 112 CHD children were divided into CHD group and CHD+PAH group and all of them underwent TDI examination. The TDI-Tei and TDI-Z of the two groups were measured respectively, and the serum miR-34a level of the children was detected by qRT-PCR test. The results showed that the TDI-Tei of the CHD group was significantly lower than that of the CHD+PAH group(P<0.001), the TDI-Z of the CHD group was significantly higher than that of the CHD+PAH group(P<0.001), the relative expression of serum miR-34a in CHD group was significantly lower than that in CHD+PAH group(P<0.001). Correlation analysis showed that TDI-Tei was negatively correlated with TDI-Z (r=-0.325, P<0.01), TDI-Tei was positively correlated with serum miR-34a (r=0.260, P<0.01), TDI-Z was negatively correlated with serum miR-34a (r=-0.386, P<0.01). The AUC and the sensitivity of TDI-Tei, TDI-Z and serum miR-34a combined diagnosis of CHD complicated with PAH were higher than those of single diagnosis. In conclusion, TDI combined with serum miR-34a has higher value in the diagnosis of CHD complicated with PAH, and was worthy of clinical promotion.
