Pericardiotomy for Prevention of Postoperative Atrial Fibrillation After Cardiac Surgery in China
Pericardiotomy for Prevention of Postoperative Atrial Fibrillation After Cardiac Surgery in China
PRINCE-CH is a multicentre, randomized controlled trial which evaluates the effectiveness and safety of posterior pericardiotomy in preventing POAF after cardiac surgery in Chinese population.
Postoperative atrial fibrillation (POAF), defined as new-onset atrial fibrillation (AF) in the immediate period after surgery, is the most important type of secondary AF, which complicates 20-40% patients receiving cardiac surgery.
POAF is associated with haemodynamic instability , increased risk of stroke, lengthened hospital and intensive care unit stays and greater costs.
Pericardial effusion accumulated posterior to the left atrium after cardiac surgery could trigger atrial arrhythmias. Pericardiotomy allows for prolonged drainage of the pericardial effusion into left pleural space. Recent research evidence found that pericardiotomy was associated with a significantly lower incidence of POAF. The existing data on posterior pericardiotomy is promising for a reduction in POAF. The PRINCE trial's long-term follow-up of patients randomized to pericardiotomy could conclusively demonstrate whether the relationship of POAF to post-discharge clinical outcomes is causal and modifiable.
The PRINCE-CH trial will evaluate the effectiveness and safety of pericardiotomy in preventing POAF after cardiac surgery in Chinese population.
The intervention is posterior pericardiotomy and the control is no posterior pericardiotomy during cardiac surgery. The primary outcome is the occurrence of POAF.
The study will enrol 650 patients from 15 centres in China. All participants will be continuously monitored using a wearable body surface electrocardiogram (EKG) monitoring equipment from the day of surgery to 30 days after surgery.
