Pleural and Pericardial Effusion Following Open Heart Surgery (IMAGING)
The Clinical Impact of an Aggressive Approach Towards Pleural and Pericardial Effusions Following Open Heart Surgery: a Step Towards Standard Guidelines

Intervention / Treatment
Detailed Description
Introduction:
Knowledge concerning the impact of pleural and pericardial effusions on physical performance, recovery-time, cardiac and respiratory complications, and quality of life after open cardiac surgery is scarce. A more aggressive approach towards effusions has been suggested, but further studies are needed.
Objectives:
- to determine the size of pleural and pericardial effusion that results in at least 30% reduction of physical performance in the 6-minute walk test.
- to compare the improvement in physical performance between the intervention group and the control group, measured from baseline to day 30 after surgery.
Materials and methods:
A randomised controlled intervention trial. Patients admitted for open cardiac surgery (aortic valve surgery, coronary artery bypass graft surgery and combinations) will be randomised into either an intervention group or a control group. The intervention group will be followed with physical tests and ultrasonic examination the month following surgery. Pleural or pericardial effusion of a predefined size will be drained. The control group will follow the current postoperative regimen.

Description
Inclusion Criteria:
- Age >18 years.
- Admitted for elective aortic valve surgery, coronary artery bypass graft surgery or combinations.
- Be able to understand the written and oral patient information and to give informed consent.
Exclusion Criteria:
- Surgical combinations involving the mitral valve since they are already examined with full echocardiography prior to discharge, which may influence protocol driven decisions.
- Simultaneous participation in any other clinical intervention trial

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: current postoperative regimen
The group will follow the current postoperative regimen at the surgical ward; screening for pleural effusions with x-ray and further diagnostic procedures in case of symptoms.
Treatment will be entirely in the hands of the clinical personnel.
|
|
Experimental: pleuracentesis
The group will follow the current postoperative regimen.
In addition they will be followed with ultrasound examination, clinical examination, spirometry examination and 6 minute walk test.
In case of either a) pleural effusion > 400ml OR b) pleural effusion< 400ml with symptoms in rest or during the walk test, the effusion will be drained and examinations will be repeated.
In case of pericardial effusion of predefined size and location, either the surgeon on call or a cardiologist will be consulted.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
change in walking distance before and after intervention
Time Frame: day 4, day 15, day 30
|
The primary outcome measure is the change in walking distance before and after pleuracentesis, subsequently the size of pleural effusion (both cm measured on ultrasound and drained volume) that results in a reduction of distance in the 6 minute walk test of at least 30%.
|
day 4, day 15, day 30
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
change in walking distance from baseline to day 30 after surgery
Time Frame: day 0 and day 30
|
The difference in walking distance from before surgery (day 0) to after surgery (day 30) will be compared between the intervention arm (+ pleuracentesis) and the control arm (standard postoperative regimen)
|
day 0 and day 30
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
needle pleuracentesis versus pigtail catheter
Time Frame: day 0, day 4, day 15 and day 30
|
To asses how much of the pleural effusion is drained when performing needle puncture instead of inserting a pigtail catheter.
Secondary to compare the complication rate of the two procedures.
|
day 0, day 4, day 15 and day 30
