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
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

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.

Summary

This study tested whether making a small cut in the sac around the heart (posterior pericardiotomy) during open-heart surgery can prevent a common complication called atrial fibrillation. 210 adults having elective heart surgery in Yemen were randomly assigned to receive either the extra incision or standard care. The main goal was to see if fewer people in the incision group developed atrial fibrillation before leaving the hospital.

What this could mean

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

Active substance
Posterior pericardiotomy (a small incision made in the sac around the heart during open-heart surgery)
What this could lead to
If it works, this simple procedure could become a standard addition to heart surgery to prevent a common and serious complication.
What could go wrong
This is a single-center study in Yemen, so results may not apply to all populations. The procedure also carries a small risk of bleeding or other surgical complications.
