OBJECTIVE
The aim of this study was to use tissue Doppler imaging to evaluate the left atrial systolic and the left ventricular (LV) diastolic function as well as the left atrial ejection force in children who underwent transcatheter closure of a secundum atrial septal defect (ASD).

METHODS
Tissue Doppler measurements of the left atrial ejection force, the mitral valve, and left atrial volume were performed before the ASD closure procedure, and on the 1st day, 10th day, and 1st and 3rd months after the procedure in 56 patients and in 28 healthy controls.

RESULTS
There was a significant decrease in the septal and lateral a’ velocities on the first day (p<0.05). There was a statistically significant increase in the septal e’/a’ parameters at the third month compared with the initial measurements. The left atrial ejection force was lower in patients with an ASD than in the healthy group (10.69±4.94 kdyn, 12.31±4.05 kdyn, respectively), but there was no significant difference (p=0.053). The left atrial ejection force was significantly greater in the patient group 3 months after the procedure, and there was no significant difference compared with the control group.

CONCLUSION
Improvement in the LV diastolic and left atrial systolic functions was observed in children who underwent transcatheter closure of an ASD. There was no negative effect related to the devices used.
