In a 56-year-old male undergoing on-pump CABG, coronary sinus VTI measured by transesophageal echocardiography increased from 7.06 cm at anesthesia induction to 12.48 cm before chest closure.

Does velocity time integral (VTI) measurement of the coronary sinus using TEE during on-pump CABG aid in evaluating the therapeutic efficacy of coronary perfusion improvement in a patient with severe ischemic cardiomyopathy?
Intraoperative TEE measurement of coronary sinus VTI may serve as a useful tool to assess the immediate therapeutic efficacy of coronary perfusion improvement during on-pump CABG.
Absolute Event Rate: 12.48% vs 7.06%
In on-pump coronary artery bypass grafting (CABG) and left ventricular reconstruction, velocity time integral (VTI) measurement of the coronary sinus (CS) using transesophageal echocardiography (TEE) was useful for evaluating the therapeutic effect of coronary artery reconstruction and recovery of cardiac function. In a 56-year-old male with severe ischemic cardiomyopathy, CS VTI increased significantly from 7.06 cm at induction of anesthesia to 12.48 cm before chest closure, a favorable graft pulsatility index (<3) and improved myocardial perfusion were observed alongside. In this case, we report that the use of VTI measurement of the coronary sinus during on-pump CABG as an intraoperative assessment tool can aid in evaluating the therapeutic efficacy of coronary perfusion improvement.
Keisuke Sumii (Sun,) conducted a case report in Severe ischemic cardiomyopathy (n=1). Velocity Time Integral (VTI) measurement of the coronary sinus using TEE vs. Baseline (after induction of anesthesia) was evaluated on Coronary sinus VTI (cm). In a 56-year-old male undergoing on-pump CABG, coronary sinus VTI measured by transesophageal echocardiography increased from 7.06 cm at anesthesia induction to 12.48 cm before chest closure.
