Introduction: Strain imaging provides information on local myocardial deformation. Global left (LV) & right (RV) ventricular function is impaired to varying degrees in surgically repaired tetralogy of Fallot (rTOF) patients. Using strain imaging we assessed the local deformation characteristics of different regions of the LV+RV.
Method: rTOF patients were compared to normal controls. All subjects were imaged in the apical 2+4-chamber views superimposed with tissue Doppler imaging data. Longitudinal strain was calculated off line by placing the sample volume in the mid-ventricular and basal segments of the lateral, septal, inferior & anterior walls of the LV & the free wall of the RV. The results were averaged from 3 cardiac cycles.
Results are expressed as mean (±SD). 24 rTOF patients were compared to 15 age matched normal controls (31.38±10.38yrs v 32.07±9.87yrs, p=NS). There was no significant difference in
