Subtotal Pericardiectomy and Epicardiectomy for Treatment of Septic Pericarditis and Constrictive Epicarditis in a Dog.

A 1 yr old, 1.7 kg, spayed female Chihuahua was presented for respiratory distress and an enlarged cardiac silhouette as seen on thoracic radiographs. Echocardiogram revealed pericardial effusion and cardiac tamponade. Computed tomography revealed marked pleural and pericardial effusion, thickening of the pericardium caudally, and a mass along the mediastinum. Pericardial fluid obtained via pericardiocentesis showed suppurative inflammation with mixed anaerobic bacteria isolated on culture. Subtotal pericardiectomy and partial lung lobectomy was performed to treat septic pericarditis. Postoperative echocardiogram showed increased right-sided pressures consistent with constrictive epicarditis, and 10 days after surgery, the dog was re-presented for right-sided heart failure. An epicardectomy was performed. A definitive source of infection was not identified, although a penetrating foreign body (e.g., grass awn) was suspected. The dog recovered and 10 yr follow up revealed no evidence of constrictive pathology on echocardiogram. This case report demonstrates the successful treatment of septic pericarditis and constrictive epicarditis via subtotal pericardiectomy and epicardiectomy.

The Association of Minimally Invasive Surgical Approaches and Mortality in Patients with Malignant Pleuropericarditis-A 10 Year Retrospective Observational Study.

Background and Objectives: Malignant neoplasms are common causes of acute pleuropericardial effusion. Pleuropericarditis denotes poor patient prognosis, is associated with shortened average survival time, and represents a surgical emergency. Materials and Methods: We analyzed the impact of two minimally invasive surgical approaches, the type of cancer, and other clinical variables on the mortality of 338 patients with pleuropericarditis admitted to an emergency hospital in Romania between 2009 and 2020. All patients underwent minimally invasive surgeries to prevent the recurrence of the disease and to increase their life expectancy. Log-rank tests were used to check for survival probability differences by surgical approach. We also applied univariate and multivariate Cox proportional hazard models to assess the effect of each covariate. Results: No significant differences were found in the 2-year overall survival rate between patients who underwent the two types of surgery. The multivariate Cox proportional regression model adjusted for relevant covariates showed that age, having lung cancer, and a diagnosis of pericarditis and right pleural effusion increased the mortality risk. The surgical approach was not associated with mortality in these patients. Conclusion: These findings open up avenues for future research to advance the understanding of survival among patients with pleuropericarditis.

[Infectious Thoracic Aortic Aneurysm and Purulent Pericarditis due to Staphylococcus aureus:Report of a Case].

The objective of this case report is to highlight a rare case of infectious thoracic aortic aneurysm and purulent pericarditis simultaneously in a 56-year-old woman. The patient complained of left anterior chest pain and contrast computed tomography (CT) revealed infectious thoracic aortic aneurysm and purulent pericarditis accompanied by massive pericardial effusion. She underwent a pericardial drainage immediately, and antibiotic treatment was initiated. Methicillin-sensitive Staphylococcus aureus was detected in blood and pericardial fluid cultures. On day eight of hospitalization, contrast CT scan showed enlargement of the aortic aneurysm. Therefore, total arch replacement was performed on day 10 using rifampicin-soaked graft. After surgery, antibiotic treatment was continued, till inflammatory markers became negative. She was discharged on day 66 without developing anastomotic pseudoaneurysms nor constrictive pericarditis.

Recognizing Cutibacterium acnes as a cause of infectious pericarditis: A case report and review of literature.

Cutibacterium acnes is an anaerobic bacterium commonly thought of as a culture contaminant rather than a pathogen. We present a case of Cutibacterium acnes pericarditis in a 22-year-old immunocompetent woman managed with surgical pericardial window and a 4-week course of penicillin G and review related literature on Cutibacterium acnes pericarditis.

Immediate Postoperative Results in the Surgical Treatment of Neoplastic Pericarditis - 76 Consecutive Cases.

Introduction: Pericardial effusion, accumulation of fluid in the pericardial sac, may develop in any type of cancer. It was revealed in up to 20% of oncological patients. Method: We made a retrospective study of patients with pericardial efusion presented in our clinic between 2010 and 2015. We included 76 consecutive patients with indication for peri cardial drainage - we performed on them 80 surgical procedures: pericardocentesis, subxiphoid pericardial window, left paraxifoidian pericardial window, intercostal video-assisted thoracic surgery (VATS) pericardial fenestration, and classical thoracic surgery (fenestration or partial pericardiectomy). We had patients with ages between 28 and 83 years. 23 patients were admitted with cardiac tamponade. The immediate postoperatory survival is 97.3 % and the 30-days-postoperatory survival is 81.5 %. Results: The immediate postoperatory mortality is 2.7% and the 30-days-postoperatory mortality is 8.5%. Conclusions: The immediate prognosis of the patient with malignant pericardial effusion is influenced by the risk of postoperative Low-Cardiac-Output-Syndrome (LCOS), or pericardial decompression syndrome (PDS), which remains the main cause of mortality. The long-term prognosis is related to the type of malignant tumor. The most effective tehnique with the lowest rate of recurrence is pericardo-pleural window done thoracoscopically/ by VATS; pericardocentesis has the highest rate of recurrence - 90% and is associated with high rates of cardiac complications and mortality.

Severe purulent pericarditis caused by invasive Eikenella corrodens: case report and literature review.

BACKGROUND: Eikenella corrodens is a slowly growing gram-negative bacillus that can cause severe invasive disease in human. Although E. corrodens infections in various sites of human body have been well described, pericarditis caused by invasive E. corrodens has rarely been reported. CASE PRESENTATION: Here we report the case of a 63-year old male with a complaint of left shoulder pain. The patient was diagnosed as purulent pericarditis by chest computed tomography scan and ultrasound-guided pericardiocentesis, and the pathogen of E. corrodens was identified in the pericardial fluid culture. The clinical condition of the patient deteriorated quickly, and he died right after the drainage surgery even though the pathogen was sensitive to antibiotics treatment. CONCLUSION: E. corrodens is a rare pericarditis associated pathogen. Purulent pericarditis caused by E. corrodens presents atypical manifestations and rapid progression of infection in immunosuppressed individuals such as neutropenic patients. Earlier diagnosis and proper drainage surgery with effective antibiotics treatment may improve the prognosis.

Radical Pericardiectomy for Pericardial Diseases.

PURPOSE OF REVIEW: The surgical management of constrictive pericarditis has evolved from a partial pericardiectomy via a thoracotomy approach to a more extensive removal of the pericardium. This review summarizes the published studies regarding surgical management of pericardial disease, focusing on the surgical technique of radical pericardiectomy for constrictive pericarditis. RECENT FINDINGS: Anterior phrenic to phrenic resection without the use of cardiopulmonary bypass has been performed in many centers. This approach achieves improvement in symptoms; however, there are patients who have progressive constriction of the remaining pericardium requiring a completion pericardiectomy. Recent studies show that the survival and functional outcome is superior after a complete pericardiectomy. Our approach is to perform a complete pericardiectomy using cardiopulmonary bypass. In experienced centers, the outcomes have significantly improved with careful selection of patients, advances in pre- and postoperative care, and refinement in surgical techniques.

Acute-Onset Chest Pain in a 17-Year-Old Female Adolescent With Systemic Lupus Erythematosus.

We report the case of a 17-year-old adolescent girl with systemic lupus erythematosus with disseminated pneumococcal infection leading to purulent pericarditis with cardiac tamponade. Although pericarditis is not an uncommon entity in autoimmune diseases such as systemic lupus erythematosus, purulent pericarditis is a rare cause (<1%) of this presentation.

[A Case of Chronic Myelogenous Leukemia That Developed Fibrous Pericarditis Owing to Nilotinib Use].

A 64-year-old man was diagnosed with chronic-phase chronic myelogenous leukemia(CML)in May 2009. He was treated with imatinib and achieved complete cytogenetic response(CCyR)in 2 months. After 4 months of treatment, he developed interstitial pneumonia and became intolerant to imatinib. He was then switched to nilotinib from October of the same year. In June 2013, he was diagnosed with drug-induced pericarditis resulting from nilotinib use, and thus, nilotinib was discontinued. Subsequently, he was followed up without specific treatment for CML. In January 2014, he was admitted to the Dept. of Cardiovascular, Renal and Metabolic Medicine at our hospital because of heart failure. After examinations of cardiac function, he was diagnosed with constrictive pericarditis. Therefore, pericardiolysis was performed by the Dept. of Cardiovascular Surgery at our hospital. Pathologic findings showed hyaline-like fibrous tissue proliferation in the pericardium, which was diagnosed as fibrous pericarditis induced by nilotinib. We report a case of chronic myelogenous leukemia that developed fibrous pericarditis owing to nilotinib use.

[Surgical treatment results of chronic pericardial tamponade].

Objective: To report the efficacy of chronic pericardial effusion treatment with pericardial window creation through video-assisted thoracoscopic surgery and pericardial drainage through a small subxiphoid incision. Material and Methods: Retrospective analysis of 31 patients after pericardial window creation through video-assisted thoracoscopic surgery (PW group) and 77 patients where pericardial drainage through small subxiphoid incision (PD group) was performed. Echocardiography examinations were performed to document pericardial tamponade and pericardial effusion recurrence. Results: Length of surgery was 20.5±5.4 minutes in the PD group and 25.8±6.4 minutes in the PW group, p<0.001. Amount of fluid evacuated from pericardium during surgery was 483±191 ml and 521±253 ml in PD and PW groups respectively, p=0.654. Postoperative drainage was maintained longer (4.3±1.4 days vs. 3.2±1.0, p<0.001) and the amount of fluid drained after surgery was higher (497±351 ml vs. 309±231 ml, p=0.031) in the PW group. The amount of pericardial fluid at the end of hospitalization was statistically significantly higher in the PD group compared with the PW group (8.9±4.9 mm vs. 4.9±3.2 mm, p<0.001). Hospital stay was 5.7±2.7 days in the PD group and 6.1±3.4 in the PW group, p=0.112. No patient died during hospitalization period in either group. Mortality within 30 days after surgery was 2.6% in the PD and 3.2% in the PW group (p=0.642). In the PW group there were 4 conversions to right minithoracotomy due to dense pleural adhesions. Pericardial effusion recurrence occurred in 9 patients (12.0%) in the PD group and none was observed (0.0%) in the PW group (p=0.042) within 30 days after surgery. Conclusion: Pericardial window creation through video-assisted thoracoscopic surgery should be considered the preferred method over pericardial drainage through a small subxiphoid incision for chronic pericardial effusion and pericardial tamponade treatment to reduce the frequency of pericardial effusion reoccurrence.

[Pericardiectomy of effusive constrictive pericarditis with an ultrasonic scalpel; report of a case].

Effusive constrictive pericarditis is a rare clinical entity characterized by concurrent pericardial effusion and visceral pericardial constriction. The most effective therapy for this state is pericardiectomy with complete removal of the parietal and visceral membranes, although the perioperative mortality and morbidity can be high. We presented a case of a 45-year-old man in whom a visceral pericardiectomy with waffle procedure was successfully performed using an ultrasonic scalpel without use of cardiopulmonary bypass. His postoperative course was uneventful and cardiac hemodynamics restored to normal. There were no signs or symptoms of recurrence in 2 years of follow-up.

Pericardiectomy in children <15 years of age.

Between January, 2002 and December, 2011, 27 patients (19 boys) underwent pericardiectomy. The mean age was 9.3 ± 4.96 years (range 0.4 to 15 years) and the mean duration of symptoms was 16.9 ± 22.15 months. In all, 25 patients had dyspnoea; eight were in New York Heart Association (NYHA) class IV; six had bacterial pericarditis; and 18 were on anti-tuberculosis treatment, although only nine had records suggesting tuberculosis. There were nine patients who underwent pre-operative pigtail catheter drainage of pericardial fluid. Surgical procedures were complete pericardiectomy (n = 20), partial pericardiectomy (n = 6), and pleuropericardial window (n = 1).The mean pre-operative right atrial pressure was 20.4 ± 4.93 mmHg. There were six hospital deaths due to low cardiac output (n = 5) and arrhythmia (n = 1). The mean intensive care unit stay was 2.7 ± 1.2 days and mean post-operative stay was 9.9 days. The mean right atrial pressure dropped to 8.7 ± 1.15 mmHg. Adverse outcomes defined as death/prolonged intensive care unit stay, prolonged post-operative stay were not associated with sex, diagnosis of tuberculosis or pyopericardium, or the duration of symptoms or pre-operative right atrial pressure. Younger patients had prolonged intensive care unit stay (p = 0.03) but not increased mortality. Advanced NYHA class predicted death (p = 0.02). The mean follow-up was 23.1 ± 23.8 months. All except one survivor are in NYHA class I and off all cardiac medications. Despite adequate surgery, pericardiectomy in children is associated with a high mortality, which is related to delayed surgery and poor pre-operative general condition. No specific pre-operative variable other than worse pre-operative NYHA class is a predictor of survival. Therefore, early pericardiectomy should be undertaken in such patients.

[Complications after cardiac injuries].

An analysis of 293 victims with cardiac and pericardium injuries was made. Cardiac complications could appear suddenly and be registered on any stage of treatment process. They differentiated by character and duration of wound process. Pericarditis took place in 288 patients. The syndrome of system inflammation reaction was noted in 47.9% of patients, a sepsis (sometimes severe sepsis) was in 14.3%. Complications in postoperative period were determined by posthypoxic and hemic hypoxia, coagulopathy. They were manifested by myocardial ischemia and thromboembolic complications. An acute myocardial infarction took place in 29 (9.8%) cases and rhythm and conductivity abnormalities were in 23 (7.8%) patients. The circulatory failure with clinical picture of pulmonary edema was developed in 12 (4.1%) cases. The lethality consisted of 44 (15%) patients.

Pericardial Diseases and Best Practices for Pericardiectomy: JACC State-of-the-Art Review.

Remarkable advances have occurred in the understanding of the pathophysiology of pericardial diseases and the role of multimodality imaging in this field. Medical therapy and surgical options for pericardial diseases have also evolved substantially. Pericardiectomy is indicated for chronic or irreversible constrictive pericarditis, refractory recurrent pericarditis despite optimal medical therapy, or partial agenesis of the pericardium with a complication (eg, herniation). A multidisciplinary evaluation before pericardiectomy is essential for optimal patient outcomes. Overall, given the good outcomes reported, radical pericardiectomy on cardiopulmonary bypass, if feasible, is the preferred approach. Due to patient complexity, as well as the technical aspects of the surgery, pericardiectomy should be performed at high-volume centers that have the required expertise. The current review highlights the essential features of this multidisciplinary approach from diagnosis to recovery in patients undergoing pericardiectomy.

Pericarditis After Catheter Ablation for Atrial Fibrillation: Predictors and Outcomes.

BACKGROUND: Catheter ablation is a mainstay of atrial fibrillation (AF) treatment. Acute pericarditis after ablation is 1 of the frequently observed complications. There is a significant lack of data on the incidence and predictors of postablation pericarditis. OBJECTIVES: This study examines the incidence, characteristics, and predictors of pericarditis after AF ablation. METHODS: Patients undergoing AF ablation from January 1, 2016, to March 31, 2022, at Johns Hopkins were prospectively enrolled in an AF ablation registry. A clinical diagnosis of acute pericarditis was established in accordance with 2015 European Society of Cardiology guidelines by the presence of at least 2 of the following characteristics: pleuritic chest pain, friction rub, typical electrocardiographic changes, or pericardial effusion within 3 months after the ablation procedure. RESULTS: Of 1,540 patients who underwent AF ablation, 57 patients (3.7%) developed acute pericarditis. Baseline clinical characteristics including age, sex, and body mass index were comparable between the pericarditis and nonpericarditis groups. The median time to symptom onset was 1 day. Electrocardiographic changes were observed in 34 (59.6%) patients, pericardial effusion developed in 7 (12%) patients, and the mean duration of medical treatment was 7 days (25th-75th percentile: 3-14 days). Most pericarditis cases were treated medically with disease-specific nonsteroidal anti-inflammatory drugs (100%) and colchicine (81%). Effusion with tamponade necessitating pericardiocentesis was observed in 4 (7%) patients. Radiofrequency (RF) ablation was performed in 869 (58.6%) patients in the nonpericarditis group and 39 (68.4%) patients with pericarditis; cryoballoon ablation was performed in 486 (32.8%) patients in the nonpericarditis group and 11 (19.3%) patients with pericarditis. Multivariable logistic regression analysis identified RF ablation (OR: 2.09; 95% CI: 1.07-4.08; P = 0.03) as an independent predictor of acute pericarditis after AF ablation, whereas age per unit increase was associated with a decreased risk (OR: 0.97; 95% CI: 0.95-0.995; P = 0.02). CONCLUSIONS: The incidence of acute pericarditis after catheter ablation in our study population was 3.7%. RF ablation and younger age were independent risk factors for postablation acute pericarditis.

[Case report: Purulent pericarditis caused by candida species--a rare but life-threatening disease in intensive care medicine]. / Kasuistik: Die purulente Candida-Perikarditis--Ein seltenes, aber lebensbedrohliches Krankheitsbild in der Intensivmedizin.

We report a case of a male patient with drug abuse in his medical history who was hospitalized because of a community acquired pneumonia. Subsequently the patient developed an acute lung injury (ARDS) and a fulminant purulent pericarditis accompanied by a pericardial effusion. Caused by the pericardial tamponade cardiac function was severely restricted. Due to fast diagnosis and immediate adequate therapy such as systemic anti-fungal treatment, pericardiocentesis, percutaneous drainage, and later surgical intervention the patient was treated successfully. This article describes etiology, pathophysiology and symptoms of purulent Candida-pericarditis and gives a review of existing literature regarding this extremely rare disease. In addition therapeutic options are discussed.

Thoracoscopic pericardial drainage for gastric tube ulcer penetrated into the pericardium.

Peptic ulcer occurring in the gastric conduit for esophageal reconstruction sometimes penetrates into the mediastinal structures. We herein reported a case of pericardial penetration of gastric tube ulcer successfully treated with thoracoscopic pericardial drainage. A 66-year-old Japanese man, who had undergone esophagectomy for esophageal cancer 20 months before, visited our emergency room complaining severe back pain. Computed tomography revealed gastric tube ulcer penetrated into the pericardial space. Thoracoscopic pericardiotomy and drainage was performed and the patient made an uneventful recovery. Thoracoscopic pericardial drainage is useful to manage acute pyogenic pericarditis due to penetration of peptic ulcer which occurred in the gastric tube.

Chronic pericardial effusion secondary to a influenza virus A (H1N1)/2009 infection.

We report, to our knowledge, the first successful treatment of novel Influenza A (H1N1)/2009 chronic pericardial effusion in an adult. This patient presented on admission respiratory failure and cardiac tamponade which required non invasive ventilation and drainage. Pericardial fluid polymerase chain reaction sequences were positive for Influenza A (H1N1)/2009 virus. Any other etiologies were discarded. Recidivating pericardial effusion after medical treatment, firstly with Oseltamivir, and afterwards, with colchicine and corticosteroids during six months, was solved with pericardiectomy.
