Effect of PDA Closure on the Left Ventricular Remodeling

Status Not yet recruiting

Clinical Trial Summary

failure of closure of the ductus arteriosus after birth results in a congenital anomaly known as patent ductus arteriosus. The large ductus can induce left side heart remodeling changes which could interfere with the normal cardiac function.

Clinical Trial Description

Patent ductus arteriosus (PDA) is a congenital heart disease that represents 6-11% of all congenital heart diseases and is due to failure of spontaneous closure of a normal foetal duct called ductus arteriosus, that is a duct connecting the left pulmonary artery to the aorta, and it may result in LV volume overload , pulmonary overflow that may end with development of Eisenmenger syndrome. LV volume overload of the big ductus induce left heart remodeling changes in form of LA and LV dilatation, and LV hypertrophy to compensate for the increased wall stress. Some patients compensate well and remain asymptomatic, while others can't and develop manifestations of LV systolic dysfunction . Traditional echocardiography is the main diagnostic tool for the PDA and assessment of its hemodynamic effect on the heart. speckle tracking echocardiography ( STE) is a relatively novel tool that can assess the LV function by tracking the speckles of the grey scale 2D images. Recent studies revealed good correlation between the LVEF measured by traditional echocardiography and global longitudinal strain (GLS) measured by STE , in addition to detection of subtle myocardial dysfunction by STE in patients with heart failure with preserved LVEF before frank LV systolic dysfunction is apparent clinically . PDA closure should induce reverse remodelling with improvement of the left heart dimensions and function . Many studies in pediatrics showed deterioration of LVEF early after PDA closure followed by rapid recovery , while fewer studies showed late improvement of the LVEF in the adults . ;
