Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This study will check how well a heart surgeon's visual estimate of the heart's pumping ability matches the more precise measurement from an ultrasound (TEE) during open-heart surgery. About 70 adults having planned heart surgery with a heart-lung machine will take part. The goal is to see if the surgeon's quick look is accurate enough to guide decisions when removing the heart-lung machine.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could show that a surgeon's quick visual check is reliable enough to guide decisions, potentially reducing the need for extra tests during heart surgery.
What could go wrong
This is a small, early-stage study (70 participants) comparing two standard methods, not testing a new treatment. Results may not apply to all patients or surgeries.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients undergoing elective cardiac surgery requiring cardiopulmonary bypass at a single tertiary university hospital. The study population consists of individuals receiving CABG, valve surgery, or aortic surgery who meet eligibility criteria and undergo routine intraoperative TEE monitoring. Participants represent a typical clinical population of moderate-to-high surgical risk (ASA III-IV).

Ages

18 to 75 years

Inclusion Criteria: * Age between 18 and 75 years * Scheduled for elective cardiac surgery requiring cardiopulmonary bypass (CABG, valve surgery, or aortic surgery) * ASA physical status III-IV * Able and willing to provide written informed consent * Suitable for intraoperative transesophageal echocardiography (TEE) Exclusion Criteria: * Emergency surgery * Known severe preoperative left ventricular dysfunction (EF \< 30%) * Significant arrhythmias (e.g., atrial fibrillation) * Preoperative requirement for mechanical circulatory support (e.g., IABP) * Contraindications to TEE (esophageal pathology, bleeding risk, strictures) * Inability to provide informed consent
