surgery 36 Central Message 37 Posterior pericardial drainage was found to reduce postoperative complications, among others 38 cardiac tamponade and atrial fibrillation In addition, it improved survival after heart surgery 39 Perspective Statement 40 Pericardial effusion may be a source of morbidity following heart surgeries Posterior 41 pericardial drainage allows free escape of the fluid to the pleural space or on the outside via 42 chest tubes Previous studies showed that by reducing the amount of pericardial effusion one 43 can avoid postoperative atrial arrhythmias; whether other postoperative complications may be 44 reduced remains unresolved AC C EP TE D 34 ACCEPTED MANUSCRIPT Abstract 46 Objectives: The objective of the current systematic review and meta-analysis was to 47 investigate the potential beneficial effects of posterior pericardial drainage in patients 48 undergoing heart surgery 49 Methods: Multiple on-line databases and relevant congress proceedings were screened for 50 randomized controlled trials (RCTs) assessing efficacy and safety of posterior pericardial 51 drainage defined as posterior pericardiotomy incision; chest tube to posterior pericardium or 52 both Primary endpoint was in-hospital/30 days cardiac tamponade Secondary endpoints 53 comprised death or cardiac arrest; early- and late pericardial effusion; postoperative atrial 54 fibrillation (POAF); acute kidney injury (AKI); pulmonary complications; length of hospital 55 stay 56 Results: Nineteen RCTs enrolling N=3,425 patients were included Posterior pericardial 57 drainage was associated with a significant 90% reduction of the odds of cardiac tamponade as 58 compared to control group: OR (95%CIs) 0.13 (0.07-0.25); p20 1 cm was considered significant 20mm and compression
