Echocardiography (echo) is frequently performed postoperatively to evaluate patients suspected of having cardiac tamponade or pericarditis. The overall incidence and significance of echocardiographic pericardial effusions (PE) early after cardiac surgery are unknown. Therefore, M-mode and 2-dimensional (2-D) echo were used to study 39 stable patients 4 to 10 days after cardiac surgery. Twenty-two patients (56%) had unequivocal moderate-to-large PEs. PEs were identified on serial chest x-rays in only 6 patients. PEs were significantly more common after heavy postoperative bleeding, and occurred in 16 of 19 patients with more than 500 ml of total chest tube output; only 6 of 20 patients with chest tube output less than 500 ml had PE. There was no correlation of PE by echo with pericardial friction rubs, chest pain or atrial arrhythmias. Elevated erythrocyte sedimentation rate did not correlate with PE by echo or clinical pericarditis. In 1 of 22 patients with PE, tamponade developed, and the patient required reoperation on day 5; the other 21 were discharged without related therapy. Thus, early postoperative PEs are common and related to postoperative bleeding. Because they do not correlate with symptoms of pericarditis and rarely lead to tamponade, their identification is usually of limited clinical significance.

Systematic review and meta-analysis of randomized controlled trials assessing safety and efficacy of posterior pericardial drainage in patients undergoing heart surgery
2017, Journal of Thoracic and Cardiovascular Surgery
To investigate the potential beneficial effects of posterior pericardial drainage in patients undergoing heart surgery.
Multiple online databases and relevant congress proceedings were screened for randomized controlled trials assessing the efficacy and safety of posterior pericardial drainage, defined as posterior pericardiotomy incision, chest tube to posterior pericardium, or both. Primary endpoint was in-hospital/30 days' cardiac tamponade. Secondary endpoints comprised death or cardiac arrest, early and late pericardial effusion, postoperative atrial fibrillation (POAF), acute kidney injury, pulmonary complications, and length of hospital stay.
Nineteen randomized controlled trials that enrolled 3425 patients were included. Posterior pericardial drainage was associated with a significant 90% reduction of the odds of cardiac tamponade compared with the control group: odds ratio (95% confidence interval) 0.13 (0.07-0.25); P < .001. The corresponding event rates were 0.42% versus 4.95%. The odds of early and late pericardial effusion were reduced significantly in the intervention arm: 0.20 (0.11-0.36); P < .001 and 0.05 (0.02-0.10); P < .001, respectively. Posterior pericardial drainage significantly reduced the odds of POAF by 58% (P < .001) and was associated with significantly shortened (by nearly 1 day) overall length of hospital stay (P < .001). Reductions in postoperative complications translated into significantly reduced odds of death or cardiac arrest (P = .03) and numerically lower odds of acute kidney injury (P = .08).
Posterior pericardial drainage is safe and simple technique that significantly reduces not only the prevalence of early pericardial effusion and POAF but also late pericardial effusion and cardiac tamponade. These benefits, in turn, translate into improved survival after heart surgery.
Clinical features associated with adverse events in patients with post-pericardiotomy syndrome following cardiac surgery
2014, American Journal of Cardiology
Postpericardiotomy syndrome (PPS) may be associated with tamponade and pericardial constriction that may require procedural intervention. The aim of this study was to identify clinical features associated with adverse events requiring procedural intervention in patients with PPS. A total of 239 patients who developed PPS after cardiac surgery were monitored for 12 months. PPS was diagnosed if 2 of the 5 following findings were present: fever without infection, pleuritic pain, friction rub, pleural effusion, and pericardial effusion (<60 days after surgery). The primary end point was the development of pericardial effusion or pericardial constriction requiring procedural intervention. Among 239 patients with PPS, 75 (31%) required procedural intervention. In a univariate analysis, the odds of a procedural intervention were decreased with older age (odds ratio [OR] 0.98, 95% confidence interval [CI] 0.96 to 0.99) and with colchicine used in combination with anti-inflammatory agents (OR 0.45, 95% CI 0.26 to 0.79). However, the odds were increased in patients with preoperative heart failure (OR 1.84, 95% CI 1 to 3.39) and early postoperative constrictive physiology (OR 5.77, 95% CI 2.62 to 12.7). After multivariate adjustment, treatment with colchicine along with anti-inflammatory agents was associated with lower odds of requiring intervention (OR 0.43, 95% CI 0.95 to 0.99). Independent positive predictors of procedural intervention included age (OR 0.97, 95% CI 0.95 to 0.99), time to PPS (OR 0.97, 95% CI 0.95 to 0.99), and early postoperative constrictive physiology (OR 6.23, 95% CI 2.04 to 19.07). In conclusion, younger age, early-onset PPS, and postoperative constrictive physiology were associated with the need for procedural intervention in patients with PPS, whereas colchicine was associated with reduced odds of adverse events and procedural intervention.
Management of cardiac tamponade after cardiac surgery
2012, Journal of Cardiothoracic and Vascular Anesthesia
Citation Excerpt :
Precipitating factors include the administration of anticoagulants, coagulation disorders, excessive mediastinal bleeding, the removal of epicardial pacing wires after cardiac surgery,5,6 autoimmune reactions, and the development of postpericardiotomy syndrome. Late tamponade (>7 days after surgery) is considered to be a significant postoperative complication of cardiac surgery, with a higher mortality rate than early tamponade.7-9 Among postoperative patients with severe delayed pericardial effusions, the 30-day mortality rate was 3%.
Effects of prophylactic indomethacin treatment on postoperative pericardial effusion after aortic surgery
2011, Journal of Thoracic and Cardiovascular Surgery
Citation Excerpt :
Early PE is a common finding after cardiac surgery.3,4 The incidence of significant PE is between 1% and 6%.2,17-19 It has been reported that after aortic surgery PEs are often loculated and that even small amounts of fluid in the posteromedial wall, in the posterolateral wall, or along the free walls of the right atrium and ventricle can considerably disturb the cardiac functions or cause cardiac arrhythmias.2,4
This prospective, randomized study assessed the prophylactic effects of indomethacin treatment on pericardial effusion after aortic surgery.
Eighty-five patients were found eligible to participate in this double-blind study. Patients were assigned to a control group receiving oral placebo or to an indomethacin group receiving 25 mg oral indomethacin 3 times daily for 7 days preoperatively. After aortic surgery, patients were followed up clinically and evaluated for pericardial effusion with transthoracic echocardiography on the first and seventh postoperative days during hospitalization and at the second and sixth weeks after discharge.
The demographic and the operative data were similar between groups. The surgical interventions included Bentall procedure in 63 patients, valve-sparing procedures in 7 patients, and supracoronary ascending aorta replacement in 15 patients. Hemiarch replacement was performed in 16 patients. No patient in either group had pericardial effusion after the first postoperative day. At the end of the first week, however, 2 patients had pericardial effusion, at the end of the second week after discharge, 3 patients had pericardial effusion, and at the end of the sixth week after discharge, 4 patients had PEs. One of the patients who had PE at the end of the sixth week received indomethacin; the others were all in the control group, a significant difference (P = .019). Five patients underwent transthoracic echocardiographically guided pericardiocentesis; 4 underwent surgical pericardiocentesis.
Indomethacin may have beneficial effects on the outcomes and incidence of postoperative pericardial effusion after aortic surgery.
Prevalence of Pericardial Effusions in Children With Large Atrial or Ventricular Septal Defect
2009, American Journal of Cardiology
Recently, a high percentage of adults with isolated secundum atrial septal defects (ASD) and ventricular septal defects (VSD) undergoing surgical repair had a circumferential pericardial effusion (PE), preoperatively. It was our impression that PEs are uncommon in children with unrepaired ASD or VSD. To evaluate this impression, we performed a retrospective study to determine the prevalence of PE in children with ASD compared with those with VSD and with children with normal cardiac anatomy. The preoperative echocardiograms of 90 patients with isolated surgical grade secundum ASDs, 75 patients with isolated VSDs, and 91 normal patients were reviewed to evaluate for the presence or absence of pericardial effusions and also the septal defect size. Only 1 patient (ASD group) of the total 256 had a global PE (0.4%). No large effusions were found in any group. Eighty-one children (32%) had any effusion present in the pericardial space. The prevalence of these small PEs was not significantly different between the ASD (36/90, 40%) and VSD (23/75, 31%, p = 0.25) groups. The patients with ASD, however, had a significantly higher prevalence of PEs compared with the control group (22/91, 24%, p <0.03). In conclusion, the presence of global PEs in children with surgical grade ASD or patients with VSD is rare, unlike that reported in adults with the same lesions. Trace effusions are found more commonly in children with ASD than those in VSD or in normal children, which may herald a potential for larger effusions with a longer time before defect closure.
