Official Title: The Clinical Impact of an Aggressive Approach Towards Pleural and Pericardial Effusions Following Open Heart Surgery: a Step Towards Standard Guidelines
Brief Summary: One of the most common postoperative complications after open cardiac surgery is fluid accumulation between the pleural membranes or in the pericardial sac. This study investigates the consequence of such fluid accumulations on physical performance, recovery-time, cardiac and respiratory complications, and quality of life. Half of the participants will be followed closely and offered fluid drainage at a low threshold, and half of the participants will follow the current postoperative regimen.
