2D Speckel Tracking of RV Function after CABG and CPB Time

Abstract

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.
