BACKGROUND
Left atrial systolic and left ventricular diastolic functions were evaluated with tissue doppler imaging and left atrial ejection force in children who underwent transcatheter closure of secundum atrial septal defect.

METHODS
Measurements of left atrial ejection force, mitral valve tissue doppler and left atrial volume were performed before the procedure, and first day, tenth day, first and third months after the procedure in 56 patients and 28 healthy controls.

RESULTS
There was a significant decreasing in septal and lateral a' velocities in first day (p <0.05). There was a statistically significant increase in septal e'/a' parameters in third months according to the beginnings. Left atrial ejection force were lower in patients with atrial septal defect than healty group (10.69± 4.94, 12.31± 4.05 kilodyne, respectively), but there was no significant difference (p= 0.053). Left atrial ejection force was significantly increased after three months in the patient group and there was no significant difference in control groups.

CONCLUSION
The improvement of left ventricular diastolic and left atrial systolic functions was detected in children who underwent transcatheter closure of atrial septal defects. There was no negative mechanical effect of the device
