Aim: To investigate the relation between the postoperative RV dysfunction and cardiopulmonary bypass time (CPB time) and aortic cross clamp time by comparing new echocardiographic parameter (2D speckel tracking). Methods and Results: We included 38 patients who underwent CABG between March 2019 and November 20019 in the Academic Medical Centre in Tehran. Before and one week after CABG, patients had TEE,71% were male. There was statistically significant decrease in RVGLS from (-19 to -11) after CABG. There w ere significant correlation between Pre op TAPES and FAC (P value=0.002), pre op FAC and Sv (P value=0.001), Pre op TAPES and GLS (P value=0.011) and Pre op Sv and GLS (P value=0.013) And there was significant correlation between post op TAPES and FAC (P value=0.045) and Post op Sv and GLS (P value=0.04), Conclusion: There is not significant correlation between decline in RV function parameter (TAPES, GLS, FAC, Sv) and cardiopulmonary bypass time and aortic cross clamp time.
