Assessment of the right ventricular function before and after coronary artery bypass surgery by conventional and tissue Doppler echocardiography

Aim of the work To study extent right ventricular (RV) dysfunction in ischemic patients after coronary artery bypass grafting (CABG). Patients and methods RV function was studied preoperatively followed for 1 month postoperatively 40 who were scheduled elective surgery other controls. We evaluated by tissue Doppler tricuspid annulus basal septum, annular plane systolic excursion, dimensions. Both LV dimensions, left atrium aortic root dimensions also measured before surgery. Results significantly reduced CABG as assessed pulsed-wave imaging both septum. There a significant reduction excursion CABG, but there no difference Moreover, LVEDD CABG. Conclusion remained depressed
