RÉSUMÉ
Laparoscopic intraperitoneal onlay mesh repair is favoured for diaphragmatic hernias due to better outcomes. However, fixation devices pose risks, including cardiac tamponade. A man underwent laparoscopic repair for a large diaphragmatic hernia. One week later, he presented with chest discomfort which was initially attributed to postoperative pain. Subsequently, patient represented with worsening of chest pain and tachycardia. CT requested to rule out pulmonary embolism revealed a large pericardial effusion. Urgent drainage via apical approach resolved tamponade. The case highlights the challenges in managing pericardial effusions post-laparoscopy in the presence of diaphragmatic mesh and stresses multidisciplinary collaboration. Literature review highlights risks associated with fixation devices. Suggestions include limiting their use near vital structures. Key learning point of this case report is to raise awareness of cardiac tamponade following diaphragmatic hernia repair. Limited evidence necessitates cautious use of fixation devices, emphasising patient safety.

BACKGROUND Effusive-constrictive pericarditis (ECP) is an uncommon clinical syndrome characterized by the coexistence of pericardial effusion and constriction involving the visceral pericardium. This differs from constrictive pericarditis, which presents with thickening of the pericardium without effusions. Specific diagnostic criteria of ECP include the failure of right atrial pressure to decrease by 50% or reach a new level below 10 mmHg after normalization of intrapericardial pressure. CASE REPORT We present the case of a 32-year-old obese man with multiple comorbidities who initially presented with flu-like symptoms and pleural effusion with development of constrictive-like symptoms. Despite undergoing numerous pericardiocentesis and appropriate medical management, the patient's condition failed to improve, leading to the likely diagnosis of effusive-constrictive pericarditis. Cultures of pericardial fluid revealed E. -faecium, which required multiple antimicrobial therapy. Despite infection, the exact etiology of ECP remained unknown and likely idiopathic. Common causes of ECP include idiopathic, tuberculosis, cardiac surgery complications, radiation, or neoplasia. Ultimately, the patient underwent a pericardiectomy involving the visceral and parietal pericardium, resulting in hemodynamic stability and resolution of symptoms. CONCLUSIONS This case highlights the challenges in diagnosing and managing ECP, emphasizing the importance of considering surgical intervention in refractory cases. ECP initially presents as a pericardial effusion, often addressed through pericardiocentesis; however, in a small subset of patients, sustained symptoms and altered hemodynamics persist following pericardiocentesis, necessitating further evaluation and management. The success of pericardiectomy in our patient highlights the potential efficacy of surgical intervention in improving outcomes for patients with ECP.

Point-of-care ultrasound (POCUS) has been shown to be a valuable tool in the management of acutely ill patients in the prehospital setting. POCUS not only has utility from a diagnostic perspective but also has been shown to reduce the rate of complications from otherwise traditionally "blind" procedures, such as pericardiocentesis. This case report highlights the utility of POCUS in the prehospital setting to guide emergent pericardiocentesis to treat cardiac tamponade. The applicability of various approaches to ultrasound-guided pericardiocentesis is also discussed.

Fetal pericardial teratomas are rare. They present with pericardial effusion and hydrops. The definitive management is postnatal resection of the tumor. The exact antenatal management is not known due to its rarity. We present a case of fetal pericardial teratoma with pericardial tamponade. Pericardiocentesis performed at 31 weeks significantly relieved the venous compression, leading to resolution of hydrops and prolonging the gestational age for the definitive management.

The patient is a 76-year-old man. His chief complaint of chest pain led to a diagnosis of pericardial effusion of unknown cause, and pericardial drainage was performed. On the 30th day, chest pain appeared again. Echocardiography revealed a pericardial fluid reaccumulation and a substantial mass in the pericardial space. Surgical drainage was performed to find the cause. A hematoma/mass was present on the epicardium. The pericardial sac was filled with hematoma. The hematoma was removed, but part of the mass infiltrated close to the anterior descending branch of the left coronary artery, and removal of that part was abandoned. The intrapericardial hematoma and epicardium were submitted to pathology leading to the diagnosis of synovial sarcoma. The patient was discharged home 14 days after surgery.

BACKGROUND: Acute type A aortic intramural hematoma (ATAIMH) is a variant of acute type A aortic dissection (ATAAD), exhibiting an increased risk of hemopericardium and cardiac tamponade. It can be life-threatening without emergency treatment. However, comprehensive studies of the clinical features and surgical outcomes of preoperative hemopericardium in patients with ATAIMH remain scarce. This retrospective study aims to investigate the clinical features and early and late outcomes of patients who underwent aortic repair surgery for ATAIMH complicated with preoperative hemopericardium. METHODS: We investigated 132 consecutive patients who underwent emergency ATAIMH repair at this institution between February 2007 and August 2020. These patients were dichotomized into the hemopericardium (n = 58; 43.9%) and non-hemopericardium groups (n = 74; 56.1%). We compared the clinical demographics, surgical information, postoperative complications, 5-year cumulative survival rates, and freedom from reoperation rates. Furthermore, multivariable logistic regression analysis was utilized to identify independent risk factors for patients who underwent re-exploration for bleeding. RESULTS: In the hemopericardium group, 36.2% of patients presented with cardiac tamponade before surgery. Moreover, the hemopericardium group showed higher rates of preoperative shock and endotracheal intubation and was associated with an elevated incidence of intractable perioperative bleeding, necessitating delayed sternal closure for hemostasis. The hemopericardium group exhibited higher blood transfusion volumes and rates of re-exploration for bleeding following surgery. However, the 5-year survival (59.5% vs. 75.0%; P = 0.077) and freedom from reoperation rates (93.3% vs. 85.5%; P = 0.416) were comparable between both groups. Multivariable analysis revealed that hemopericardium, cardiopulmonary bypass time, and delayed sternal closure were the risk factors for bleeding re-exploration. CONCLUSIONS: The presence of hemopericardium in patients with ATAIMH is associated with an elevated incidence of cardiac tamponade and unstable preoperative hemodynamics, which could lead to perioperative bleeding tendencies and high complication rates. However, patients of ATAIMH complicated with hemopericardium undergoing aggressive surgical intervention exhibited long-term surgical outcomes comparable to those without hemopericardium.

BACKGROUND: Previous case studies have reported reversal of acute renal failure after pericardiocentesis in pericardial effusion. This study examines the effects of pericardiocentesis on preprocedural low cardiac output and acute renal dysfunction in patients with pericardial effusion. METHODS: This is a retrospective study of 95 patients undergoing pericardiocentesis between 2015 and 2020. Pre- and post-procedure transthoracic echocardiograms (TTE) were reviewed for evidence of cardiac tamponade, resolution of pericardial effusion, and for estimation of right atrial (RA) pressure and cardiac output. Laboratory values were compared at presentation and post-procedure. Patients on active renal replacement therapy were excluded. RESULTS: Ninety-five patients were included for analysis (mean age 62.2 ± 17.8 years, 58% male). There was a significant increase in glomerular filtration rate pre- and post-procedure. Fifty-six patients (58.9%) had an improvement in glomerular filtration rate after pericardiocentesis (termed "responders"), and these patients had a lower pre-procedure glomerular filtration rate than "non-responders." There was a significant improvement in estimated cardiac output and right atrial pressure for patients in both groups. Patients who had an improvement in renal function had significantly lower pre-procedural diastolic blood pressure and mean arterial pressure. CONCLUSIONS: Pericardial drainage may improve effusion-mediated acute renal dysfunction by reducing right atrial pressure and thus systemic venous congestion, and by increasing forward stroke volume and perfusion pressure.

BACKGROUND: Chylopericardium is a rare condition characterized by the accumulation of chyle in the pericardial space. It is most commonly caused by thoracic duct injury. Chylopericardium following esophagectomy is extremely rare but can cause life-threatening complications. This report presents a case of chylopericardium post-esophagectomy, resulting in cardiac tamponade and cardiac arrest. A systematic literature review was also conducted to facilitate the understanding of this rare condition. CASE PRESENTATION: A 41-year-old male was admitted to our hospital with intermediate to highly differentiated squamous cell carcinoma of the mid-thoracic esophagus (clinical T4NxM0). He underwent thoracoscopic-laparoscopic esophagectomy with cervical anastomosis. On postoperative day 1, patient had a cardiac arrest secondary to cardiac tamponade, requiring emergency ultrasound-guided drainage. The drained fluid was initially serous but became chylous after the administration of enteral nutritional emulsion. As a result of significant daily pericardial drainage, patient subsequently underwent thoracic duct ligation. The amount of drainage was substantially reduced post-thoracic duct ligation. Over a period of 2 years and 7 months, patient recovered well and tolerated full oral diet. A comprehensive literature review was conducted and 4 reported cases were identified. Among these cases, three patients developed pericardial tamponade secondary to chylopericardium post-esophagectomy. CONCLUSION: Chylopericardium is a rare but serious complication post-esophagectomy. Prompt echocardiography and thorough pericardial fluid analysis are crucial for diagnosis. Thoracic duct ligation has been shown to be an effective management approach for this condition.

OBJECTIVE: Pericardial tamponade, which increases postoperative mortality and morbidity, is still not uncommon after paediatric cardiac surgery. We considered that posterior pericardiotomy may be a useful and safe technique in order to reduce the incidence of early and late pericardial tamponade. Herein, we present our experience with creation of posterior pericardial window following congenital cardiac surgical procedures. METHODS: This retrospective study evaluated 229 patients who underwent paediatric cardiac surgical procedures between June 2021 and January 2023. A posterior pericardial window was created in all of the patients. In neonates and infants, pericardial window was performed at a size of 2x2 cm, whereas a 3x3 cm connection was established in elder children and young adults. A curved chest tube was placed and positioned at the posterolateral pericardiophrenic sinus. An additional straight anterior mediastinal chest tube was also inserted in every patient. Transthoracic echocardiographic evaluations were performed daily to assess postoperative pericardial effusion. RESULTS: A total of 229 (135 male, 94 female) patients were operated. Mean age and body weight were 24.2 ± 26.7 months and 10.2 ± 6.7 kg, respectively. Eight (3.5%) of the patients were neonates where 109 (47.6%) were infants and 112 (48.9%) were in childhood. Fifty-two (22.7%) re-do operations were performed. Six (2.6%) patients underwent postoperative surgical re-exploration due to surgical site bleeding. Any early or late pericardial tamponade was not encountered in the study group. CONCLUSIONS: Posterior pericardial window is an effective and safe technique in order to prevent both the early and late pericardial tamponade after congenital cardiac surgery.

OBJECTIVE: This study compared outcomes in patients with solid tumor treated for pericardial effusion with surgical drainage versus interventional radiology (IR) percutaneous drainage and compared incidence of paradoxical hemodynamic instability (PHI) between cohorts. BACKGROUND: Patients with advanced-stage solid malignancies may develop large pericardial effusions requiring intervention. PHI is a fatal and underreported complication that occurs following pericardial effusion drainage. METHODS: Clinical characteristics and outcomes were compared between patients with solid tumors who underwent s urgical drainage or IR percutaneous drainage for pericardial effusion from 2010 to 2020. RESULTS: Among 447 patients, 243 were treated with surgical drainage, of which 27 (11%) developed PHI, compared with 7 of 204 patients (3%) who were treated with IR percutaneous drainage ( P =0.002); overall incidence of PHI decreased during the study period. Rates of reintervention (30-day: 1% vs 4%; 90-day: 4% vs 6%, P =0.7) and mortality (30-day: 21% vs 17%, P =0.3; 90-day: 39% vs 37%, P =0.7) were not different between patients treated with surgical drainage and IR percutaneous drainage. For both interventions, OS was shorter among patients with PHI than among patients without PHI (surgical drainage, median [95% confidence interval] OS, 0.89 mo [0.33-2.1] vs 6.5 mo [5.0-8.9], P <0.001; IR percutaneous drainage, 3.7 mo [0.23-6.8] vs 5.0 mo [4.0-8.1], P =0.044). CONCLUSIONS: With a coordinated multidisciplinary approach focusing on prompt clinical and echocardiographic evaluation, triage with bias toward IR percutaneous drainage than surgical drainage and postintervention intensive care resulted in lower incidence of PHI and improved outcomes.

OBJECTIVE: Aortic annulus rupture remains one of the most fatal complications of TAVR. While attempts have been made to describe and predict this complication, the data remains insufficient without evidence-based guidelines for management of this rare complication. METHODS: Here we describe a series of 3 aortic annulus ruptures after TAVR which were managed successfully to hospital discharge. RESULTS: Patient 1 suffered annulus rupture during balloon valvuloplasty prior to TAVR. The patient became hypotensive, and echocardiogram showed pericardial effusion. The patient underwent pericardiocentesis which transiently improved the blood pressure, but bleeding continued. The patient was transitioned to an open surgical aortic valve replacement due to ongoing hemorrhage. The chest was left open with delayed closure on post-op day 2. The patient was discharged on post-op day 15. Patient 2 was undergoing TAVR valve expansion. The patient became hypotensive. An echocardiogram revealed pericardial effusion. Pericardiocentesis yielded 200 mL of blood. SURGIFLO (Johnson & Johnson Wound Management, Somerville, NJ) was injected into the pericardial space. Aortic root angiography confirmed no further contrast extravasation. A pericardial drain was left in place for 2 days, and the patient was discharged on post-op day 7. Patient 3 received a TAVR valve and post-placement dilation due to paravalvular leak. The echocardiogram showed a pericardial effusion. Pericardiocentesis was performed, yielding 500 cc of blood. The patient's healthcare proxy declined emergent surgery; thus, a pericardial drain was placed. No hemostatic agents were used, and drainage reduced over several hours. The drain was removed on post-op day 3, and the patient was discharged on post-op day 8. CONCLUSIONS: Based on the timelines in these three cases, and interventions used, the following steps may be employed in the event of annulus rupture: identification of hemodynamic instability, echocardiogram to confirm pericardial effusion, emergent pericardiocentesis, pericardial drain placement for evacuation of the pericardial space and use of hemostatic agents, repeat aortogram to rule out ongoing extravasation. If hemostasis is unable to be achieved and/or the patient becomes hemodynamically unstable at any point, rapid transition to emergent surgical management is necessary. This management strategy proved successful for this case series and warrants further investigation.

PURPOSE OF REVIEW: The purpose of this article is to serve as a practical guide to computed tomography (CT)-guided pericardiocentesis and to discuss the role of this approach in current clinical practice. An overview of indications, technique, advantages, and limitations specific to CT-guided pericardiocentesis will be provided. The reader will have an enhanced understanding of the use of this imaging modality to guide pericardial drainage. RECENT FINDINGS: Use of CT guidance to drain the pericardial space is safe, especially when adequate echocardiographic evaluation is precluded and when echocardiography-guided pericardiocentesis is deemed unsafe and or not feasible. Our review and experience indicate that CT-guided pericardiocentesis is technically successful in more than 94% of patients, with a low risk (<1%) of significant complications. CT-guided pericardiocentesis is therefore a viable alternative when echocardiographic guidance is insufficient and can obviate the need for surgery in most patients.

BACKGROUND: Pericardial window, in addition to promoting pericardial drainage, can also provide samples of the pericardium for anatomopathological examination. However, such biopsies' contribution to clarifying the etiology of pericardial effusion has been debated. OBJECTIVE: To analyze the diagnostic value of non-targeted pericardial biopsy obtained from pericardial window procedures. METHODS: Data from 80 patients who had undergone parietal pericardial biopsies from 2011 to 2020 were retrospectively reviewed. Statistical significance was considered if p < 0.05. RESULTS: Fifty patients were male (62.5%,) and 30 were female (37.5%). The median age was 52 years (interquartile range: 29 to 59) and 49 years (interquartile range: 38 to 65), respectively (p = 0.724). The suspected etiology of pericardial effusion was neoplastic in 31.3%, unclear in 25%, tuberculosis in 15%, autoimmune in 12.5%, edemagenic syndrome in 7.5%, and other miscellaneous conditions in 8.8%. The most frequent approach for pericardial drainage and biopsy was subxiphoid (74%), followed by video-assisted thoracoscopy (22%). Overall, in 78.8% of the biopsies, the histopathologic findings were compatible with nonspecific inflammation, and only 13.7% of all biopsies yielded a conclusive histopathological diagnostic. Those suffering from cancer and pericardial effusion had a higher proportion of conclusive histopathologic findings (32% had pericardial neoplastic infiltration). The hospital mortality rate was 27.5%, and 54.5% of the patients who died in the hospital had cancer. No deaths were attributed to cardiac tamponade or the drainage procedure. CONCLUSION: Our results showed that pericardial window is a safe procedure, but it had little value to clarify the pericardial effusion etiology and no impact on the planned therapy for the primary diagnosis besides the cardiac decompression.
FUNDAMENTO: A janela pericárdica, além de promover a drenagem pericárdica, também pode fornecer amostras do pericárdio para exame anatomopatológico. No entanto, a contribuição dessas biópsias para a elucidação da etiologia do derrame pericárdico tem sido debatida. OBJETIVO: Analisar o valor diagnóstico da biópsia pericárdica não guiada obtida de procedimentos de janela pericárdica. MÉTODOS: Foram revisados retrospectivamente dados de 80 pacientes submetidos a biópsia pericárdica parietal de 2011 a 2020. A significância estatística foi considerada quando p < 0,05. RESULTADOS: Cinquenta pacientes eram do sexo masculino (62,5%) e 30 do sexo feminino (37,5%). A mediana de idade foi de 52 anos (intervalo interquartil: 29 a 59) e 49 anos (intervalo interquartil: 38 a 65), respectivamente (p = 0,724). A etiologia suspeita do derrame pericárdico foi neoplásica em 31,3%, incerta em 25%, tuberculose em 15%, autoimune em 12,5%, síndrome edemigênica em 7,5% e outras condições diversas em 8,8%. A abordagem mais frequente para drenagem pericárdica e biópsia foi a subxifoide (74%), seguida pela videotoracoscopia (22%). Em 78,8% das biópsias, os achados histopatológicos foram compatíveis com inflamação inespecífica, e apenas 13,7% de todas as biópsias produziram um diagnóstico histopatológico conclusivo. Aqueles que sofriam de câncer e derrame pericárdico apresentaram maior proporção de achados histopatológicos conclusivos (32% apresentavam infiltração neoplásica pericárdica). A taxa de mortalidade hospitalar foi de 27,5% e 54,5% dos pacientes que morreram no hospital tinham câncer. Nenhuma morte foi atribuída ao tamponamento cardíaco ou ao procedimento de drenagem. CONCLUSÃO: Nossos resultados mostraram que a janela pericárdica é um procedimento seguro, mas teve pouco valor para esclarecer a etiologia do derrame pericárdico e nenhum impacto na terapia planejada para o diagnóstico primário além da descompressão cardíaca.

Pericardial effusions secondary to tumors are commonly metastatic, originating primarily from the lung, breast, and lymphomas. Pericardial tamponade is a rare oncological emergency warranting early identification and treatment. We describe a 66-year-old male found to have a large bloody pericardial effusion causing tamponade physiology, and multimodality imaging was consistent with intrapericardial malignancy with no identifiable primary source. He was subsequently diagnosed with type B3 thymoma after mediastinal resection.
