| Popis: | Background The pathogenic mechanism for the development of left ventricular (LV) dysfunction in patients with asymptomatic pre-excitation syndrome has not yet been fully elucidated. We sought to assess the impact of pre-excitation on LV systolic function and whether the use of tissue Doppler imaging (TDI) and speckle tracking is more helpful in detection of the LV dyssynchrony than conventional echo parameters in these patients. Methods This observational case control study was carried out on adults with manifest pre-excitation syndromes. A detailed echocardiographic assessment was performed including TDI and speckle tracking examination. Results Our study patients were divided into two groups, group 1: with lateral accessory pathways (AP) (23 patients aged 31.65 ± 6.5 years), group 2: with septal AP (25 patients, 34.84 ± 10.8 years). Echocardiography showed a lower ejection fraction (EF) in group 2 than in group 1 (0.60 ± 0.07% in group 1 vs. 0.50 ± 0.08% in group 2, p = 0.000). The radial strain dyssynchrony index was higher in group 2 than in group 1 (58.78 ± 33.47 vs. 139.52 ± 21.14 ms; p |
