Background: Pneumopericardium is a rare complication of epicardial ablation after dry pericardiocentesis to treat ventricular arrhythmia (VA); its exact clinical effects on patients are still unclear. The purpose of this study was to evaluate the clinical effects of pneumopericardium during epicardial ablation on patients with VA., Methods: Patients with VA who underwent epicardial catheter ablation under local anesthesia at West China Hospital of Sichuan University from August 2012 to January 2022 were enrolled in this study. The incidence of pneumopericardium was investigated. The occurrence of major adverse cardiovascular events (MACEs) was evaluated 1 year after the operation., Results: A total of 86 VA patients were included in the study. Twenty-two cases had pneumopericardium, with an incidence rate of 25.6%, and 12 (54.55%) patients complained of dyspnea during the procedure with an average occurrence time of 5.4 ± 3.2 min after pericardiocentesis. The blood pressure (BP) decreased significantly, with the mean BP dropping from 119.8/73.2 to 103.5/64.9 mmHg (p < 0.001). None of the cases progressed to tension pneumopericardium. Postoperative follow-up with a median period of 411 days showed that the incidence rate of major adverse cardiovascular events (MACEs), including the composite endpoints of all-cause death, rehospitalization for heart failure, and tachyarrhythmia events, was 36.4% (n = 8) in the pneumopericardium group and 35.5% (n = 23) in the non-pneumopericardium group. The Kaplan-Meier survival analysis showed that there was no statistically significant difference in the incidence of MACEs between the two groups (p = 0.28)., Conclusions: The incidence of pneumopericardium during epicardial ablation was relatively high. However, if recognized early and managed properly, it is unlikely to progress to tension pneumopericardium. The occurrence of pneumopericardium during the procedure may not significantly affect the long-term prognosis of patients., (© 2022.

Background: Both diaphragmatic hernia and thoracic gastropericardial fistula rarely occur simultaneously in patients with radical esophagectomy., Case Presentation: A 72-year-old man presented to our hospital with 1 day of nausea, vomiting and acute left chest pain. He had radical esophagectomy (Sweet approach) for esophageal cancer 18 years ago. Computed tomography (CT) of the chest revealed diaphragmatic hernias and air collection within the pericardial space. While an operation of diaphragmatic hernia repair was decisively performed to prevent further serious complications, unusually, a thoracic gastropericardial fistula was also found unusually., Conclusion: Diaphragmatic hernia and thoracic gastropericardial fistula may occasionally coexist in patients with esophagectomy. Upper GI radiograph with a water-soluble contrast agent is a better diagnostic tool than CT in visualizing the fistula.

A 44-year-old lady, a follow-up case of idiopathic dilated cardiomyopathy and cardiac resynchronization therapy defibrillator device implantation with epicardial left ventricular (LV) lead, underwent a transvenous LV lead revision in view of epicardial lead malfunction. A chest X-ray after this, done for worsening dyspnea, revealed pneumopericardium along with left pneumothorax. The computed tomography (CT) revealed a communication between the left pleural and pericardial cavities, around the old epicardial lead. Drainage of the left pleural cavity resolved both the pneumothorax and pneumopericardium and the patient remained well on follow up., (© 2020 Wiley Periodicals LLC.)

Pneumopericardium is a condition characterised by the presence of air within the pericardium. We hereby present a case of a rare potentially life-threatening complication, which is, to our knowledge, the first report of the pneumopericardium after single port endoscopic thoracic sympathectomy (SPETS). A 25-year male patient with a history of bilateral palmar hyperhidrosis underwent SPETS. Routine chest X-ray at post-anesthesia care unit showed presence of diffuse subcutaneous emphysema, helping to establish the diagnosis of pneumopericardium with no symptoms after the surgery.  Pneumopericardium should be considered among the possible complications of SPETS. Such complication may progress to a fatal event, if not recognised early and managed rapidly. Based on clinical experience, routine postoperative clinical follow-up protocols should be established and applied for each patient following SPETS.

Thoracic endometriosis is a rare entity characterized by presence of endometrial tissue in pleura, lung parenchyma or airways. Most frequent manifestations are catamenial pneumothorax, hemothorax, hemoptysis and pulmonary nodules. We report here a rare case of a woman with thoracic endometriosis who developed iterative pneumothorax and pneumopericardium on bilateral bullous pulmonary dystrophy. She was a 37-year-old woman without any tobacco exposure and with previous history of pleural tuberculosis treated 5 years earlier. She was first referred to our centre for right pleuro-pneumothorax and hemorrhagic ascites. Pleural fluid examinations did not show any tuberculosis relapse, the evolution was favorable after thoracic drainage and there was no parenchymal lung abnormality on CT scan after surgery. Celioscopic peritoneal examination revealed stage IV peritoneal endometriosis. One year later, she was admitted for left catamenial pneumothorax. Thoracic CT scan showed apparition of large subpleural bulla. She underwent thoracotomy for bulla resection and left partial pleurectomy. Two years later, she was hospitalized for right pneumothorax and compressive pneumopericardium. Surgical lung biopsies confirmed pleuropulmonary endometriosis. Thoracotomy was performed for talcage pleurodesis and diaphragmatic leakages sutures. Lung bulla are rare in thoracic endometriosis, mechanism of their formation remains unknown. Pericardial involvement is rare in endometriosis; we report here a unique case of pneumopericardium., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)

Gastric perforation into the pericardium is an extremely rare but lethal condition. Only a few case reports have been described in the literature. It is difficult to diagnose these patients with clinical evaluation. Accurate and immediate diagnosis of the intestinal perforation is vital. Herein, we present a 56-year old female patient with gastric perforation into the pericardium due to benign gastric ulcer diagnosed with computed tomography (CT). We also emphasized the imaging findings in the diagnosis of intestinal perforation into the pericardium., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Pneumopericardium is an overall rare condition caused by increased intrathoracic positive pressure. Different mechanisms can contribute to its development. It can be observed in both pediatric and adult populations. Only a small percentage of patients have cardiac tamponade. We describe the first case of delayed tension pneumopericardium after elective lobectomy. Sudden symptom onset and clinical management are discussed. Only an accurate and quick patient assessment allowed diagnosing this condition and, hence, its correct treatment. Although the diagnosis of pneumopericardium is uncommon, if untreated, it can be fatal., (Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

Tension pneumopericardium is a rare disease that is very difficult to diagnose. A 3-year old child was run over by a minibus. Computed tomography showed bilateral pneumothorax, multiple rib fractures on both sides, and a hepatic laceration. The massive blunt thoracic trauma caused entrapped air in the pericardium, and a tension pneumoprecordium developed abruptly. We report this unique case of tension pneumopericardium in a child, and the subsequent emergency surgery and damage control measures.

Introduction: The pyo-pneumopericardium is a very rare complication of an incarcerated diaphragmatic hernia. Usually, it depends on the existence of a gastropericardial fistula and, in most cases, it is a deadly complication., Case Report: We present the case of a 65 year old man who was admitted to our emergency service with clinical signs of septic shock. With the help of the CT scan a pyo-pneumopericardium and incarcerated diaphragmatic hernia was diagnosed. He was subjected to emergency surgical intervention with double approach (thoracic and abdominal), discerning during surgery the existence of a pericardial abscess due to a gastro-pericardial fistula due to an incarcerated diaphragmatic hernia. The gastric fundus was resected with abolition of the gastro-pericardial fistula, evacuation of the pericardial abscess, performing the splenectomy (in order to have a better surgical access) and adequate treatment of the diaphragmatic hernia. Despite the medical efforts, the patient died on the 10th postoperative day due to septic complications. To our knowledge this is the first case reported in the literature of gastro-pericardial fistula complicated with pyo-pneumo-pericardium due to an incarcerated diaphragmatic hernia. In such cases we consider that only by performing a double surgical approach (thoracic and abdominal) we can provide a proper resolution of the case, also based on the objective situation found during surgery, where the splenectomy can provide an easier approach to the diaphragmatic hernia., Key Words: Diaphragmatic hernia, Gastropericardial fistula, Pyo-pneumopericardium.

Introduction: A pneumopericardium presenting after penetrating chest trauma is a rare event. The surgical management of this clinical problem has not been clearly defined. The aim of this study was to document the mode of presentation and to suggest a protocol for management., Patient and Methods: A review of a prospectively collected cardiac database of patients presenting to Groote Schuur Hospital Trauma Centre between October 2001 and February 2009 with a pneumopericardium on chest X-ray after penetrating trauma., Results: There were 27 patients with a pneumopericardium (mean age 25 years, range 17-36). The mechanism of injury was a stab wound to the chest in 26 patients and a single patient with multiple low velocity gunshot wounds. Six patients (22%) were unstable and required emergency surgery. One of these patients presented with a tension pneumopericardium. Twenty-one patients were initially stable. Two of these (10%) patients later developed a tension pneumopericardium within 24-h and were taken to theatre. The remaining 19 patients were managed with a subxiphoid pericardial window (SPW) at between 24 and 48h post admission. Ten of these 19 patients (52%) were positive for a haemopericardium. Only 4 of the 19 underwent a sternotomy and only two of these had cardiac injuries that had sealed. There were no deaths in this series., Conclusion: Patients with a penetrating chest injury with a pneumopericardium who are unstable require emergency surgery. A delayed tension pneumopericardium developed in 10% of patients who were initially stable. It is our recommendation that all stable patients with a pneumopericardium after penetrating chest trauma should undergo a SPW. A sternotomy is not required in stable patients., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

Cardiac perforation is an infrequent but potentially life-threatening complication of pacemaker implantation. We report a case of right atrial lead perforation complicated by pneumopericardium shortly after pacemaker lead insertion. Transthoracic echocardiography revealed no evidence of pericardial effusion and pacemaker lead displacement, but a thoracic computed tomography scan illustrated the lead course and confirmed the diagnosis. This case suggests that computed tomography is a sensitive modality to confirm the diagnosis at the early stage of this complication.

We reported a case of a 78-year-old patient with esophagopericardial fistula who was referred for angiographic and interventional management. Emergent implantation of the esophageal stent could not lengthen or even save the patient's life. One week later, the patient died of multiple organ failure, which was probably from formation of granulation tissue and stent migration. Therefore, if the inflammatory to the esophagopericardial fistula had been better controlled initially, and the implantation of the esophageal stent delayed, our patient would have survived.

Pneumopericardium is a rare clinical finding with various etiologies. Pneumopericardium ranges from an asymptomatic to life-threatening condition, e.g., in cases of cardiac tamponade. The underlying etiology should be sought so that treatment can be expedited. Pneumopericardium may result from traumatic and nontraumatic etiologies. Although the mortality associated with pneumopericardium is high, its rarity precludes determination of its true incidence. We present an unusual case of pneumopericardium due to gastropericardial fistula which developed as a delayed complication of a Roux-en-Y gastric bypass performed 11 years prior.

Pneumopericardium is rare and has been reported secondary to chest trauma. We report a case of tension pneumopericardium occurring during double-lung transplantation, where intraoperative transoesophageal echocardiography first showed a hypokinetic left ventricle and a few minutes later a compression of its anterolateral portion due to pneumopericardium. Although the pericardium was opened, left ventricular function remained depressed, necessitating extracorporeal membrane oxygenation, which was withdrawn after 48 h of assistance when left ventricular function had recovered. The patient was extubated on the seventh postoperative day but died of multiorgan failure on the 64 th postoperative day.

Introduction: Bronchopericardial fistula is a rare condition leading to pneumopericardium. This medical condition is often related to neoplastic disease, or a complication of surgical interventions. The treatment approach depends on both the etiology and the clinical presentation. In stable patients, pericardial drain insertion and/or surgical resection of the fistula are considered options for persistent cases. We present the case of a bronchopericardial fistula treated by placement of an endobronchial stent., Case Presentation: A 64-year-old man operated on for lung cancer had a recurrence treated with radiation and chemotherapy. A pneumopericadium was discovered when he presented with a new onset of atrial fibrillation. Bronchoscopy revealed a fistula tract. Pericardial drainage was persistent and did not improve the clinical situation. The poor health status of the patient contraindicated surgery and an alternative therapeutic approach with endobronchial stent placement was undertaken. The fistula sealed immediately, the pericardial drain could be removed removed and the patient was able to be discharged from hospital., Conclusion: Endobronchial stenting should be considered as a potential treatment option in patients with pneumopericardium secondary to bronchopericadial fistula, particularly where a non-surgical is required., (Copyright © 2012 SPLF.

Background: Lead dislodgement has been shown to be the most common complication in the first 30 days after pacemaker insertion. Although it is rare, pneumopericardium with tamponade can also result., Objectives: We present a case of an extremely rare delay from cardiac pacemaker insertion to lead migration with resulting pneumopericardium and cardiac tamponade., Case Report: A 65-year-old woman with a past medical history significant for congestive heart failure, chronic obstructive pulmonary disease, and third-degree heart block, requiring pacemaker insertion 2 years prior with a revision 1 year prior, presented to the Emergency Department complaining of sudden-onset pleuritic chest pain. Her work-up revealed a pneumopericardium with atrial pacemaker lead migration into the right middle lobe of the lung. She suddenly developed hypotension and respiratory distress and required pericardiocentesis and, ultimately, surgical repair for a perforated right atrium., Conclusion: Pacemaker migration can lead to pneumopericardium and tamponade, even up to 1 year after placement., (Copyright © 2012 Elsevier Inc.

Esophageal replacement for both benign and malignant diseases commonly uses gastric tube reconstruction. A rare but potentially life-threatening late complication is the formation of a gastropericardial fistula. We describe a case of gastropericardial fistula occurring more than 20 years after esophageal reconstruction for congenital esophageal atresia. We report our surgical strategy and review the key concepts in the management of this complication., (Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc.

We present a case of large pneumopericardium resulting from an esophageal pericardial fistula following ablation for atrial fibrillation (AF). The presentation, evaluation, and management of this specific patient, along with a review of present techniques to diagnose esophageal injury, provide a unique insight into the pathophysiology of left atrial-esophageal fistula formation., (© 2010 Wiley Periodicals, Inc.)

Pneumopericardium is a rare but serious cause of morbidity and mortality. Untreated, it can lead to cardiac tamponade and thus must be promptly identified to treat the underlying etiology. Here, we report a case of spontaneous pneumopericardium secondary to gastric ulcer perforation in association with a hiatal hernia. The diagnosis of pneumopericardium was first made under fluoroscopy during cardiac catheterization and a follow-up CT of the chest revealed a gastropericardial fistula as the initiating event. The patient underwent emergent thoracotomy and partial esophagogastrectomy which eventually resulted in a full recovery and discharge on postoperative day 19. Our unique experience with this rare and often fatal disease suggests that early diagnosis combined with an early and aggressive surgical strategy is critical for minimizing morbidity and mortality., (Copyright 2009 Wiley-Liss, Inc.)

A 59-year-old woman with a history of bronchiectasis was admitted due to a two-day history of fever and hemosputum. A permanent pacemaker (DDD mode, screw-in lead) had been implanted three months previously to treat complete atrioventricular block. On computed tomography, pneumopericardium was seen, and the right atrium pacing lead was stuck into the right lung. A semi-emergency operation to remove the pacing lead and part of the right middle lobe was performed through a right thoracotomy. Although pneumopericardium caused by pacing lead perforation is rare, the possibility of perforation by the pacing lead should always be considered.

Pneumopericardium is a rare cause of cardiac tamponade. It is an exceptional complication of lung transplantation. We have presented a case of a patient with cystic fibrosis who experienced cardiac tamponade secondary to a tension pneumopericardium during the postoperative course after lung transplantation. Dehiscence of the bronchial suture line was confirmed by fiberoptic bronchoscopy.

Esophagopericardial fistula (EPF) is an uncommon complication of esophageal disease. Although, the esophagus is in direct contact with the pericardium in the lower thoracic vertebrae level, EPF is still rare. Recorded causes of EPF include ingested foreign bodies such as fish bone, benign ulceration in association with hiatus hernia, esophageal carcinoma, and achalasia. Congenital EPF occurs even less but with a high ratio of mortality and misdiagnosis. We present a case of PEF in a 1-year-old boy. It is unique in that the patient was a very young child which is rarely reported in literature and the main cause factor seemed to be repeated vomiting since birth. However, he had a good outcome with surgical treatment.

This is the case of a 56-year-old male who presented at our Emergency Room complaining of severe epigastric pain that radiated towards the left shoulder and neck. Pneumopericardium was diagnosed with plain chest X-rays, which indicated a gastropericardial fistula. A contrast X-ray film was taken using a water-soluble contrast. A full gastrectomy was performed with esophagojejunostomy reconstruction and pericardial drainage, which resulted in a favourable patient outcome.
