Abstract:

BACKGROUND: Occluder implantation in patients with congenital heart disease can increase in vivo platelet adhesion and aggregation, resulting in thrombosis on the occluder surface.

OBJECTIVE: To investigate the effect of the occluder on platelet function in patients with congenital heart disease undergoing transcatheter closure.
METHODS: Clinical data from 124 patients with congenital heart disease undergoing transcatheter closure were retrospectively analyzed. These patients were divided into groups of atrial septal defect in 46 cases, patent ductus arteriosus in 43 cases and ventricular septal defect in 35 cases according to the types of congenital heart disease. The positive rates for peripheral blood CD62p, CD63 and thrombin sensitive protein were compared before and 6 hours, 24 hours, 12 months after occluder implantation.
RESULTS AND CONCLUSION: There was no difference in the positive rates of peripheral blood CD62p, CD63 and thrombin sensitive protein among three groups prior to occluder implantation. Up to 6 hours after occluder implantation, the expression levels of peripheral blood CD62p, CD63 and thrombin sensitive protein reached peak in the three groups, especially in the patients with atrial septal defect and ventricular septal defect, then gradually decreased. After 12 months, the expression levels of CD62p and CD63 recovered in the patients with patent ductus arteriosus and ventricular septal defect, but still maintained a higher level in those with atrial septal defect (P < 0.05). The expression of thrombin sensitive protein showed no difference among the three groups at different time. These findings indicate that after occluder implantation, the platelet activation is more remarkable and lasts longer in the patients with atrial septal defect and ventricular septal defect, especially in those with ventricular septal defect.
