It is well known that myocardial ischemia leads to Regional Wall Motion Abnormalities (RWMAs) and reversible depression of Left Ventricular (LV) systolic function. Transoesophageal Echocardiography (TEE) is an established tool for early diagnosis of new RWMAs. However, evaluation of RWMAs by echocardiography is largely qualitative and relies on visual assessment of wall segments. Evaluation of LV systolic function and Ejection Fraction (EF) is more reproducible and accurate with Real-Time 3D Echocardiography (RT3DE) as compared with two-dimensional and M-mode techniques. Primary advantages for RT3DE are fast and largely automated volumetric analysis of LV function and LV volumes, without geometric assumptions and risk of underestimating volumes in foreshortened views. This case illustrates the use of intraoperative RT3DE during coronary artery bypass surgery to objectively assess: LV systolic function with LV volumes and RWMAs and improvement in cardiac synchronization following coronary reperfusion.
