Assessment of Left Ventricular Dyssynchrony and Cardiac Function in Patients with Different Pacing Modes Using Real-Time Three-Dimensional Echocardiography: Comparison with Tissue Doppler Imaging

Background: Previous studies revealed that right ventricle apex pacing with different modes may yield abnormal electrical activity and left ventricle dyssynchrony.Aim of the work: To evaluate systolic function of left ventricle and mechanical dyssynchrony with different modes of pacing using real ti...

Imaging parameters were obtained following pacing for 24 hours in each mode.Results: The results revealed that the RT3DE and TDI-derived dyssynchrony indices in the atrial demand pacing [AAI] mode were significantly lower than those in the dual chamber demand pacing [DDD] and ventricular demand pacing [VVI] modes; however, there was no significant difference between the DDD and VVI modes. Also, left ventricular ejection fraction [LVEF] during AAI and DDD modes was significantly higher than that during VVI mode; however, there was no significant difference between the DDD and AAI modes. There were negative correlations between LVEF and Ts-MD and Ts-SD, and there was positive strong correlation between RT3DE and TDI-derived dyssynchrony indices.Conclusions: Left ventricular systolic synchronicity in AAI mode was superior to that in DDD and VVI modes. Left ventricular ejection fraction in the AAI and DDD pacing modes are superior to that in the VVI mode.Waseem AhmedMansour MostafaMohamed BashandyAhmed Mohamed MostafaMohamed MoheyaldeenMohamed AbdalsameeAl-Azhar University, Faculty of Medicine (Damietta)articleleft ventricle mechanical dyssynchronydual chamber demand pacingright ventricle apextissue doppler imagingreal time three dimensional echocardiographyMedicine (General)R5-920ENInternational Journal of Medical Arts, Vol 1, Iss 2, Pp 65-72 (2019)
