Plain English Summary
Background and study aims
In patients who underwent a heart surgery called coronary artery bypass graft (CABG), posterior pericardiotomy (a surgical procedure carried out on the pericardium of the heart) has been shown to be protective against postoperative atrial fibrillation (abnormal heart rate after heart surgery). This study aims to find out whether it could help patients who underwent valve surgery.
Who can participate?
Patients admitted for aortic valve replacement surgery can participate in this study.
What does the study involve?
Patients are divided randomly into two groups. One group receives posterior pericardiotomy during the valve replacement surgery and the other group, called the control group, receives the standard surgical technique.
What are the possible benefits and risks of participating?
This technique may reduce the occurrence of postoperative atrial fibrillation and accumulation of fluid around the heart in patients who underwent aortic valve replacement surgery.
Where is the study run from?
This study is run from Ochapowski Regional Hospital, Russia.
When is the study starting and how long is it expected to run for?
The study started in October 2013 and is expected to run for 1.5 years.
Who is funding the study?
The study is funded by the Kuban State Medical University, Russia.

The efficacy of posterior pericardiotomy in prevention of atrial fibrillation and pericardial effusion after aortic valve replacement
The hypothesis is that posterior pericardiotomy can reduce the incidence of atrial fibrillation and pericardial effusion after aortic valve replacement.

Cardiac surgery postoperative atrial fibrillation and pericardial effusion
Patients will be randomised to two groups: intervention and control
1. Intervention group: will undergo posterior pericardiotomy in addition to conventional aortic valve replacement
2. Control group: will undergo only conventional aortic valve replacement
Primary outcome measure
2. The incidence of stroke
3. The incidence of cardiac tamponade
Concerned to in-hospital period.
Secondary outcome measures
1. The incidence of atrial fibrillation, measured with 48-h ECG monitoring and then with daily ECG
2. The incidence of pericardial effusion measured by echo twice after removing chest tubes and before discharge
3. The incidence of left pleural effusion measured by echo twice after removing chest tubes and before discharge
4. Length of stay in hospital
