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
Registered, but not yet taking participants.

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.

Summary

This study tested whether making a small opening in the lining around the heart (called a left posterior pericardiotomy) can prevent new atrial fibrillation after coronary artery bypass surgery. 270 adults having bypass surgery were randomly assigned to get this extra cut or not. The main goal was to see if the cut lowered the rate of atrial fibrillation before leaving the hospital.

Inclusion Criteria: * patients who are planned to undergo coronary artery bypass grafting * patients aged ≥19 years Exclusion Criteria: * patients who are planned to undergo other concomitant cardiac procedures (e.g. valve procedures, aorta procedures) * patients who undergo coronary artery bypass grafting using cardiopulmonary bypass * patients who are documented with paroxysmal, persistent, or permanent atrial fibrillation before operation * patients who have a history of cardiac surgery * patients who have a history of pericardial disease * patients who have severe adhesion at left pleural cavity which precludes effective left posterior pericardiostomy * patients who refuse to participate in this study
