What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study will test two different surgical techniques used during heart bypass surgery to see which one better prevents a common complication called atrial fibrillation (irregular heartbeat). The trial will involve 122 adults having their first planned bypass surgery. Researchers will compare making a small opening in the sac around the heart (posterior pericardial window) versus placing a drain behind the heart (retro-cardiac drain) to reduce heart rhythm issues and other problems like fluid buildup.

What this could mean

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

Active substance
surgical procedure (posterior pericardial window or retro-cardiac drain)
What this could lead to
If successful, this could establish a better standard technique to prevent irregular heartbeat and other complications after heart bypass surgery.
What could go wrong
This is a small, early-stage trial with only 122 patients, so results may not apply to everyone. The techniques are surgical and carry standard risks like bleeding or infection.

Who can take part

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

Who is studied

The study population will include adult patients scheduled to undergo elective, first-time, isolated coronary artery bypass grafting (CABG) surgery via median sternotomy. Eligible participants will be hemodynamically stable and able to provide informed consent prior to enrollment. Patients will be randomized intraoperatively to receive either a posterior pericardial window or a retro-cardiac drain for postoperative management.

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients (aged 18 and above) scheduled for elective, first-time coronary artery bypass grafting (CABG). * Patients with preserved left ventricular function (ejection fraction ≥ 35%). * Ability to provide informed consent and comply with follow-up protocols. * No prior history of atrial fibrillation or other significant arrhythmias. Exclusion Criteria: * Patients undergoing combined cardiac procedures (e.g., valve repair or replacement). * Emergency CABG cases or re-operations. * Known bleeding disorders or ongoing anticoagulation therapy that cannot be paused. * Severe pericardial adhesions or anatomical abnormalities preventing safe creation of a posterior pericardial window. * Chronic pulmonary disease or pleural pathology that may interfere with drainage assessment. * Patients with active infections or systemic inflammatory conditions.
