Summary

This trial aims to determine which CABG patients need TEE during surgery to improve outcomes.

Who is the study for?
This trial is for adults over 18 who are scheduled for low-risk isolated CABG surgery, have a good heart pump function (ejection fraction ≥50%), and recent heart tests. It's not for those with moderate or severe valve disease, planned aortic interventions, critical coronary disease, end-stage kidney disease on dialysis, certain esophageal conditions, or severe pulmonary hypertension.
What is being tested?
The study aims to determine the usefulness of using an intraoperative TEE probe during CABG surgeries. The TEE probe is used to take detailed images of the heart from inside the esophagus during surgery to guide decisions and improve outcomes.
What are the potential side effects?
While not explicitly stated in this summary, potential side effects of using a TEE probe may include sore throat, difficulty swallowing or rare complications like esophageal injury.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: As-needed TEEExperimental Treatment1 Intervention
The TEE probe is placed only in situations where a surgeon requires information that can only be obtained by ultrasound imaging of the heart.
Group II: Default TEEActive Control1 Intervention
The TEE probe is placed after going under general anesthesia and a breathing tube is placed. TEE issued to take pictures of the heart before and after a CABG surgery. If randomized to this group, the TEE probe will remain in place throughout the surgery.
