Review
Cardiac tamponade is a rare presentation in breast cancer and may be associated with poor prognosis. In this article, we reviewed the characteristics and survival outcomes of patients with breast cancer who developed cardiac tamponade. Three databases (PubMed, EMBASE and SCOPUS) were searched for relevant articles published from 1978 to 2022 and 16 articles were identified comprising 64 cases. The median age of the cases was 52 years. Cardiac tamponade was diagnosed with echocardiogram or computerized tomography of the chest or both in 91.9%, 1.6% and 6.5% of the cases, respectively. Cytology of the pericardial fluid was done in 90.5% of the cases while biopsy in addition to cytology was done in 9.5% of cases. Tamponade was proven to be malignant in 97.4% of the cases. The initial treatment for tamponade was pericardiocentesis. Adjunct therapies ranged from the insertion of a pericardial window, pericardiectomy, radiotherapy and chemotherapy. The median time from the first treatment of breast cancer to the onset of tamponade was 24 months while the median survival following diagnosis of tamponade was 13 months. There was no significant correlation (spearman rank-sum correlation coefficient= 0.35, p = 0.165) between time to tamponade (interval time from the first diagnosis of breast cancer and the onset of cardiac tamponade) and survival. Cardiac tamponade may adversely affect survival in patients with breast cancer. Early diagnosis with echocardiogram and cytology may guide management and expectations. Further observational studies are needed to determine the predictors of cardiac tamponade and optimal treatment in patients with breast cancer.

INTRODUCTION
The mainstay of the treatment of constrictive pericarditis is pericardiectomy. However, surgery is associated with high early morbidity and mortality and low long-term survival. The aim of this study is to describe our series of pericardiectomies performed over 30 years.
METHODS
A descriptive, observational, and retrospective analysis of all pericardiectomies performed at the Institute of Cardiology and Cardiovascular Surgery of the Favaloro Foundation was performed.
RESULTS
A total of 45 patients underwent pericardiectomy between June 1992 and June 2022, mean age was 52 years (standard deviation ± 13.9 years), and 73.3% were men. Idiopathic constrictive pericarditis was the most prevalent (46.6%). The variables significantly associated with prolonged hospitalization were preoperative advanced functional class (incidence of 38.4%, P<0.04), persistent pleural effusion (incidence of 81.8%, P<0.01), and although there was no statistical significance with the use of cardiopulmonary bypass, a trend in this association is evident (P<0.07). We found that 100% of the patients with an onset of symptoms greater than six months had a prolonged hospital stay. In-hospital mortality was 6.6%, and 30-day mortality was 8.8%. The preserved functional class is 17 times more likely to improve their symptomatology after pericardiectomy (odds ratio 17, 95% confidence interval 2.66-71; P<0.05).
CONCLUSION
Advanced functional class at the time of pericardiectomy is the variable most strongly associated with mortality and prolonged hospitalization. Onset of the symptoms greater than six months is also a poor prognostic factor mainly associated with prolonged hospitalization; based on these data, we strongly support the recommendation of early intervention.

: Bacteria-caused acute pericarditis is a very rare entity. It is usually associated with an underlying infection or compromised immune system. Primary purulent pericarditis in a previously healthy individual is highly unexpected; therefore, it is likely to have a delayed diagnosis and poor outcomes. : We report a case of an adult immunocompetent patient with primary bacterial pericarditis caused by a member of the commensal oral flora The patient presented with septic shock and cardiac tamponade, and was further complicated with constrictive pericarditis, which was successfully treated with pericardiectomy. : Bacterial pericarditis is a fulminant disease with a high mortality and complication rate. Fast recognition and prompt therapy are required to achieve a full recovery.

OBJECTIVE
To document outcomes of thoracoscopic treatment of idiopathic chylothorax (IC) in dogs with and without constrictive pericardial physiology (CPP) and evaluate patterns of chyle flow redistribution after thoracic duct ligation (TDL).
ANIMALS
26 client-owned dogs.
PROCEDURES
In this prospective cohort study, echocardiography and cardiac catheterization were performed to document CPP in dogs with IC. Thoracoscopic TDL with pericardiectomy was performed if CPP was present (TDL/P group). Dogs without evidence of CPP underwent thoracoscopic TDL alone (TDL group). Dogs underwent preoperative, immediate postoperative, and 3-month postoperative CT lymphangiography studies when possible. Perioperative morbidity, resolution and late recurrence rates, and long-term outcome were recorded.
RESULTS
17 dogs underwent TDL, and 9 underwent TDL/P. Twenty-five of 26 (96%) survived the perioperative period. One dog died from ventricular fibrillation during pericardiectomy. Resolution rates for TDL and TDL/P were 94% and 88%, respectively (P = .55), with 1 late recurrence occurring in the TDL group in a median follow-up of 25 months (range, 4 to 60 months). On 3-month postoperative CT lymphangiography studies, ongoing chyle flow past the ligation site was demonstrated in 5 of 17 dogs, of which 1 dog developed recurrence at 13 months postoperatively. In 15 of 17 dogs, chylous redistribution after TDL was principally by retrograde flow to the lumbar lymphatic plexus.
CLINICAL RELEVANCE
In dogs without evidence of CPP, TDL alone was associated with a very good prognosis for treatment of IC. In the absence of CPP, the additional benefit of pericardiectomy in the treatment of IC is questionable.

Surgical ligation of a patent ductus arteriosus is regarded as a standard treatment approach with a low complication rate if performed by experienced surgeons, and it has been performed successfully for decades in dogs. However, there are no reports describing the clinical symptoms related to granulomatous inflammation after the surgical ligation of the patent ductus arteriosus. This report describes the clinical symptoms caused by granulomatous inflammation and subacute pericarditis in a dog that had undergone the surgical closure of a patent ductus arteriosus 2 years previously. Exploratory thoracotomy was performed for subtotal pericardiectomy, and a biopsy was performed to obtain specimens for histopathological examination and culture tests. The clinical symptoms were relieved after surgery. The persistent leukocytosis improved with steroid administration. This case illustrates that the granulomatous inflammatory response associated with silk suture granuloma is a rare postoperative complication of ductal ligation. In such cases, pericardiectomy can help relieve the clinical symptoms.

Erdheim-Chester disease is a rare clonal non-Langerhans cell histiocytosis with multisystemic involvement. It affects bones, large vessels, and retroperitoneum. Cardiac involvement is one of the main mortality predictors. We present an unusual case that debuted with cardiac tamponade and pericardial constriction requiring pericardiectomy for definitive control. ().

INTRODUCTION
Postoperative atrial fibrillation (POAF), characterized as AF that arises 1-3 days after surgery, occurs after 30%-40% of cardiac and 10%-20% of non-cardiac surgeries, and is thought to arise due to transient surgery-induced triggers acting on a preexisting vulnerable atrial substrate often associated with inflammation and autonomic nervous system dysfunction. Current experimental studies often rely on human atrial tissue samples, collected during surgery prior to arrhythmia development, or animal models such as sterile pericarditis and atriotomy, which have not been robustly characterized.
AIM
To characterize the demographic, electrophysiologic, and inflammatory properties of a POAF mouse model.
METHODS AND RESULTS
A total of 131 wild-type C57BL/6J mice were included in this study. A total of 86 (65.6%) mice underwent cardiothoracic surgery (THOR), which consisted of bi-atrial pericardiectomy with 20 s of aortic cross-clamping; 45 (34.3%) mice underwent a sham procedure consisting of dissection down to but not into the thoracic cavity. Intracardiac pacing, performed 72 h after surgery, was used to assess AF inducibility. THOR mice showed greater AF inducibility (38.4%) compared to Sham mice (17.8%, = 0.027). Stratifying the cohort by tertiles of age showed that the greatest risk of POAF after THOR compared to Sham occurred in the 12-19-week age group. Stratifying by sex showed that cardiothoracic (CT) surgery increased POAF risk in females but had no significant effect in males. Quantitative polymerase chain reaction of atrial samples revealed upregulation of transforming growth factor beta 1 and interleukin 6 (IL6) and 18 (IL18) expression in THOR compared to Sham mice.
CONCLUSION
Here, we demonstrate that the increased POAF risk associated with CT surgery is most pronounced in female and 12-19-week-old mice, and that the expression of inflammatory cytokines is upregulated in the atria of THOR mice prone to inducible AF.

UNLABELLED
Chronic expanding intrapericardial hematoma can be treated surgically; however, a correct diagnosis is not always established, thus the condition remains untreated. A 76-year-old man was referred to us with a diagnosis of congestive heart failure. The patient had experienced blunt trauma to the chest 50 years earlier (during bar practice). Cardiac computed tomography revealed a cystic mass wrapped in a calcified membrane that was impeding inflow to the right atrium and ventricle. Cardiac catheterization revealed that the right ventricular pressure had a dip and plateau pattern. We diagnosed the patient with constrictive pericarditis-induced chronic expanding intrapericardial hematoma and agreed upon surgical management. We removed the hematoma and performed a pericardiectomy. The postoperative course was uneventful. In conclusion, chronic expanding intrapericardial hematoma can develop after blunt chest trauma and can be diagnosed precisely with cardiac computed tomography.
LEARNING OBJECTIVE
A 76-year-old man presented with congestive heart failure. The patient had experienced blunt trauma to the chest 50 years earlier. Cardiac computed tomography (CT) revealed a cystic mass within a calcified membrane that was impeding inflow in the right atrium and ventricle. We diagnosed chronic expanding intrapericardial hematoma (CEIH). We successfully removed the hematoma and performed a pericardiectomy. CEIH can develop after blunt chest trauma and could be diagnosed earlier with cardiac CT.

BACKGROUND
Mesenchymal stem cell (MSC)-derived exosomes are well recognized immunomodulating agents for cardiac repair, while the detailed mechanisms remain elusive. The Pericardial drainage pathway provides the heart with immunosurveillance and establishes a simplified model for studying the mechanisms underlying the immunomodulating effects of therapeutic exosomes.
METHODS
Myocardial infarction (MI) models with and without pericardiectomy (corresponding to Tomy MI and NonTomy MI) were established to study the functions of pericardial drainage pathway in immune activation of cardiac-draining mediastinal lymph node (MLN). Using the NonTomy MI model, MSC exosomes or vehicle PBS was intrapericardially injected for MI treatment. Via cell sorting and RNA-seq (RNA-sequencing) analysis, the differentially expressed genes were acquired for integrated pathway analysis to identify responsible mechanisms. Further, through functional knockdown/inhibition studies, application of cytokines and neutralizing antibodies, western blot, flow cytometry, and cytokine array, the molecular mechanisms were studied. In addition, the therapeutic efficacy of intrapericardially injected exosomes for MI treatment was evaluated through functional and histological analyses.
RESULTS
We show that the pericardial draining pathway promoted immune activation in the MLN following MI. Intrapericardially injected exosomes accumulated in the MLN and induced regulatory T cell differentiation to promote cardiac repair. Mechanistically, uptake of exosomes by major histocompatibility complex (MHC)-II antigen-presenting cells (APCs) induced Foxo3 activation via the protein phosphatase (PP)-2A/p-Akt/forkhead box O3 (Foxo3) pathway. Foxo3 dominated APC cytokines (IL-10, IL-33, and IL-34) expression and built up a regulatory T cell (Treg)-inducing niche in the MLN. The differentiation of Tregs as well as their cardiac deployment were elevated, which contributed to cardiac inflammation resolution and cardiac repair.
CONCLUSIONS
This study reveals a novel mechanism underlying the immunomodulation effects of MSC exosomes and provides a promising candidate (PP2A/p-Akt/Foxo3 signaling pathway) with a favorable delivery route (intrapericardial injection) for cardiac repair.
