Abstract
Introduction: Left ventricular dysfunction was observed after repair of coarctation of the aorta (COA) before development of left ventricular concentric hypertrophy. Aim: The aim of this study was to assess the the LV fuction after COA repair. Methods: Thirty pediatric patients with COA repair underwent echocardiographic examinations using conventional echo, TDI and 2D-STE. Results: There was a significant reduction of (FS, EF, MAPSE at the LW LV) in cases compared to the control group (p value < 0.05) measured by M-mode.The LV systolic function assessed by TDI and 2-D-STE showed a significant reduction of (S LW LV, IVA at LW LV, IVA at the septum, LS basal and GRS) in cases compared to control group (p value< 0.05). There is significant increase in GCS in case compared to control group, the conventional doppler derived MPI of LV in post coarctation repair cases was significantly prolonged compared to control. Analysis of mitral annulus velocities including E’, A’, E’/A’ ratio and E/E COA repair cases compared to healthy controls. The E’ wave velocity (at the left ventricular lateral wall) was significantly lower in post COA repair cases compared with controls (p value< 0.05), E’/A’ ratio was significantly lower in post COA repair cases compared with controls (p value< 0.05). The E/E compared to the control group (p value< 0.05). There was significant RV systolic dysfunction in patients with post coarctation repair compared to normal control. Significant positive correlation was found between the left ventricular mass and age of patient, duration after intervention, blood pressure in right arm, diastolic blood pressure in left leg, S’ LW LV, E’ velocity septum and averge E’. Conclusions: LV systolic and diastolic dysfunction was fount in patient after COA repair
