Bleeding sites and treatment strategies for cardiac tamponade by catheter ablation requiring thoracotomy: risks of catheter ablation in patients with left atrial diverticulum

BACKGROUND

There is insufficient information regarding the bleeding sites and surgical strategies of cardiac tamponade during catheter ablation for atrial fibrillation (AF).

CASE PRESENTATION

Of the five patients with cardiac tamponade, three required surgical intervention and two required pericardiocentesis. In the first case of three cardiac tamponades requiring surgical intervention, considering that the peripheral route was used, the catecholamines did not reach the heart, and due to unstable vital signs, venoarterial extracorporeal membrane oxygenation (VA-ECMO) was inserted. No bleeding point was identified, but a thrombus had spread around the left atrium (LA) with diverticulum. Hemostasis was achieved with adhesives placed around the LA under on-pump beating. In the second case, pericardiocentesis was performed, but the patient showed heavy bleeding and unstable vital signs. Thus, VA-ECMO was inserted. Heavy bleeding was expected, and safety was enhanced by attaching a reservoir to the VA-ECMO. The bleeding point was found between the left upper pulmonary artery and LA under cardiac arrest to obtain a good surgical view for suturing repair. In the third case, the LA diverticulum was damaged. Pericardiocentesis resulted in stable vitals, but sustained bleeding was present. A bleeding point was found at the LA diverticulum, and suture repair under on-pump beating was performed.

CONCLUSIONS

When cardiac tamponade occured in any patient with LA diverticulum, treatment could not be completed with pericardiocentesis alone, and thoracotomy was likely to be necessary. If the bleeding point could be confirmed, suturing technique is a more reliable surgical strategy than adhesive alone that leads to pseudoaneurysm. If the bleeding point is unclear, it is important to confirm the occurrence of LA diverticulum using a preoperative CT, and if confirmed, cover it with adhesive due to a high possibility of diverticulum bleeding. The necessity of CPB should be determined based on whether these operations can be completed while maintaining vital stability.

Comparison of PLANE Technique versus Standard Echocardiography Guidance for Pediatric Pericardiocentesis

Percutaneous pericardiocentesis remains a challenging and potentially dangerous procedure, particularly in small, critically ill patients. We present outcomes of the PLANE (pericardiocentesis using long-axis in-plane real-time echocardiography) technique for pediatric pericardiocentesis compared with a standard echocardiography (ECHO) guidance cohort. This was a retrospective chart review of all children undergoing percutaneous pericardiocentesis from March 2013 to February 2021 at a single center. A total of 78 procedures were performed, 52 utilizing PLANE technique and 26 utilizing standard ECHO-guidance technique. There was 100% technical success rate with only one minor complication for the entire cohort. Procedures were evenly split between the bedside intensive care unit and cardiac catheterization laboratory. PLANE technique was utilized in significantly younger (1.4 vs. 8.4 years, p  = 0.008) and smaller (11.1 vs. 31.8 kg, p  = 0.007) patients, as well as in most patients deemed high risk (postoperative < 7 days, extracorporeal membrane oxygenation (ECMO) support, and/or weight less than 5 kg; 19/22, p  = 0.021). Other patient characteristics were similar between the two groups. There was a trend toward PLANE technique utilization by noncardiology trained operators. The PLANE technique for pediatric pericardiocentesis is safe and effective and can be effectively utilized in small and high-risk patient populations. The technical similarity to other long-axis ultrasound-guided procedures may facilitate adoption and mastery by critical care trained operators.

Ultrasound-guided diagnostic pericardiocentesis in preterm infants: a case report

Pericardial effusion (PE) in pediatric population can be asymptomatic or a life-threatening event. Reports on neonates or preterm infants are scarce and generally related to pericardiocentesis of large amounts of PE in emergency situations.We describe a diagnostic pericardiocentesis in a preterm infant with small and loculated pericardial effusion and suspected cardiac mass. We used an ultrasound-guided long-axis in-plane pericardiocentesis technique, with a needle-cannula. The operator obtained a subxiphoid pericardial effusion view with a high frequency linear probe and entered the skin below the tip of the xiphoid process with a 20-gauge closed IV needle-cannula (ViaValve®). The needle was identified in its entirety as it courses through soft tissue up to pericardial sac. The main advantages of this approach are a continuous viewing and angulation of the needle through all planes of the tissue and the use of a small, practical, closed IV needle-cannula with blood control septum to prevent fluid exposure while disconnecting the syringe. This novel approach is easy and safe in neonatal population, for diagnostic or emergency drainages and can be performed at bedside in a neonatal intensive care unit.

Computed tomography values of pericardial effusion may predict chylopericardium: a case report

BACKGROUND

Idiopathic chylopericardium is a rare disease characterized by filling of the pericardial cavity with chylous fluid and has no evident cause. Secondary chylopericardium usually results from injury or damage to the thoracic duct. The most common causes of secondary chylopericardium are trauma, thoracic or cardiac surgery, and congenital lymphangiomatosis. Conservative or surgical treatment can be pursued; however, surgical treatment is required if conservative treatment is unsuccessful. Pericardiocentesis plays a crucial role in the definitive diagnosis of chylopericardium. However, although a serious complication, its occurrence is infrequent. Non-invasive methods, such as computed tomography (CT), could be useful in predicting the color or characteristics of pericardial effusion.

CASE PRESENTATION

A 37-year-old Japanese woman presented to our hospital with a cough that persisted for 1 week. Echocardiography revealed pericardial effusion, which was diagnosed as acute pericarditis and treated with loxoprofen. However, pericardial effusion increased, and the patient presented to the emergency room with cardiac tamponade 1 month later. Pericardiocentesis was performed, which confirmed that the pericardial effusion was chylopericardium. Lymphatic scintigraphy did not show any connection between the thoracic duct and pericardial cavity, and the patient was diagnosed with idiopathic chylopericardium. The patient underwent continuous drainage for 11 days. After completion of cardiac drainage, the patient was discharged from the hospital without any exacerbation. The CT attenuation value of the pericardial fluid was 11.00 Hounsfield units (HU). Compared with the other causes of pericardial effusions encountered at our hospital, the HU on CT scan of pericardial effusion was low in our study and similar to the values on CT scan of chylous ascites reported in previous studies.

CONCLUSIONS

Although idiopathic chylopericardium is rare, it should be considered an important cause of pericardial effusion. Pericardiocentesis is necessary for definitive diagnosis; however, the CT findings of pericardial effusion may help predict the presence of chylous fluid.

Direct autotransfusion in the management of acute pericardial tamponade during catheter ablation for atrial fibrillation: An imperfect but practical method

Background

Acute pericardial tamponade (APT) is one of the most serious complications of catheter ablation for atrial fibrillation (AF-CA). Direct autotransfusion (DAT) is a method of reinjecting pericardial blood directly into patients through vein access without a cell-salvage system. Data regarding DAT for APT are rare and provide limited information. Our present study aims to further investigate the safety and feasibility of DAT in the management of APT during the AF-CA procedure.

Methods and results

We retrospectively reviewed 73 cases of APT in the perioperative period of AF-CA from January 2014 to October 2021 at our institution, among whom 46 were treated with DAT. All included patients successfully received emergency pericardiocentesis through subxiphoid access guided by X-ray. Larger volumes of aspirated pericardial blood (658.4 ± 545.2 vs. 521.2 ± 464.9 ml), higher rates of bridging anticoagulation (67.4 vs. 37.0%), and surgical repair (6 vs. 0) were observed in patients with DAT than without. Moreover, patients with DAT were less likely to complete AF-CA procedures (32/46 vs. 25/27) and had a lower incidence of APT first presented in the ward (delayed presentation) (8/46 vs. 9/27). There was no difference in major adverse events (death/disseminated intravascular coagulation/multiple organ dysfunction syndrome and clinical thrombosis) (0/0/1/0 vs. 1/0/0/0), other potential DAT-related complications (fever/infection and deep venous thrombosis) (8/5/2 vs. 5/3/1), and length of hospital stay (11.4 ± 11.6 vs. 8.3 ± 4.7 d) between two groups.

Conclusion

DAT could be a feasible and safe method to deal with APT during AF-CA procedure.

Precautions When Performing Pericardiocentesis in Patients with Cardiac Tamponade-complicated Malignancy: A Case Report and Review of the Literature

A 51-year-old woman who had previously undergone left mastectomy for left breast cancer accompanied by multiple metastasis experienced worsening dyspnea. Physical and imaging assessments of the hemodynamics suggested cardiac tamponade, and emergency pericardiocentesis was successfully performed. However, immediately after the procedure, the patient's condition deteriorated rapidly and showed pulseless electrical activity. Contrast-enhanced computed tomography with continuous mechanical support demonstrated massive thrombi in both pulmonary arteries. An abrupt decrease in the central venous pressure and an increase in the venous return following pericardiocentesis might result in the migration of a deep venous thrombus and fatal acute pulmonary thromboembolism.

Diagnosis, treatment, and management of pericardial effusion- review

The hemodynamic stability of the heart and pericardium are maintained by the pericardial fluid of volume ∼10–50 ml. Pericardial effusion is associated with the abnormal accumulation of pericardial fluid in the pericardial cavity. Numerous imaging techniques are utilized to evaluate pericardial effusion including chest X-ray, electrocardiogram, transthoracic echocardiography, computed tomography scan, cardiac magnetic resonance imaging, and pericardiocentesis. Once diagnosed, there are numerous treatment options available for the management of patients with pericardial effusion. These include various invasive and non-invasive strategies such as pericardiocentesis, pericardial window, and sclerosing therapies. In recent times, few studies have been conducted to evaluate the safety and efficacy of each approach in routine clinical practice. In this review, we review the role of different modalities in the diagnosis of pericardial effusion while highlighting existing therapies aimed at the management and treatment of pericardial effusion.

Thoracoscopic Management of Iatrogenic Cardiac Perforations

AIMS

Iatrogenic cardiac perforation is an uncommon but potentially fatal complication of invasive cardiac procedures. When non-surgical management fails, urgent cardiac surgery is required. Standard surgical approach is usually through full sternotomy. However, we propose a less invasive and equally effective technique with video-assisted thoracoscopic surgery (VATS).

METHODS

This single-centre retrospective study in a tertiary hospital identified all patients requiring surgical intervention due to iatrogenic cardiac perforation over a period of 5 years. Patients were grouped by surgical approach, being either sternotomy or VATS. Primary endpoints were operating time, length of ICU stay, hospital stay, 30-day mortality and all round mortality.

RESULTS

25 patients were identified: 11 in the sternotomy-group and 14 in the VATS-group. Preoperative baseline characteristics were equal. Significant difference was found for 30-day mortality (p < 0.05). There was no difference for the other endpoints.

CONCLUSIONS

Video-assisted thoracoscopic surgery is a promising alternative to standard sternotomy for iatrogenic cardiac perforations after invasive cardiac procedures. This article is protected by copyright. All rights reserved.

Surgical Strategies for Cardiac Perforation After Catheter Ablation or Electrophysiology Study

Catheter ablation is a treatment modality which has been increasingly used for cardiac arrhythmias. However, it is not complication-free, and cardiac perforation is one of its most life-threatening complications. As surgery is usually not the first-line treatment for this emergent episode, there were only very few sporadic surgical reports in the literature. This systemic review primarily aims to collect different surgical approaches for catheter-induced cardiac perforation to help surgeons manage this kind of uncommon and critical patients. Of the 452 initially screened articles, 22 studies (38 patients) were included in the systemic review. Of all the included patients, 84% (32/38) were found to have pericardial effusion acutely following catheter-related procedures, and 16% (6/38) experienced delayed-onset episodes. Regarding the surgical procedures, four patients underwent removal of clots only, eight patients underwent suture repair of the left ventricle (LV), nine patients underwent suture repair of the right ventricle (RV), five patients underwent suture repair of the LA, and four patients underwent sutureless repair of the LV and pulmonary vein (LV 1, RV 1, pulmonary vein 1). In addition to repair of perforation sites, the concomitant combined procedures included repair of intercostal vessels (complication of pericardiocentesis) for one patient, cryoablation for two patients, and maze procedure for one patient. For cardiac perforation following catheter ablation or electrophysiology study, although the majority of the patients are treated with pericardiocentesis and medical management at first, cardiovascular surgeons have to prepare to take over if the bleeding is persistent or if the cardiac tamponade is not relieved.

Case Report: Multi-Modality Imaging of a Right Atrial Pseudoaneurysm in a Patient With Breast Cancer

Cardiac pseudoaneurysms occur when a blood vessel wall is injured and the leaking blood is collected in the surrounding tissue. They are very rare events and have a high risk of rupture and poor prognosis. We report a case of right atrial pseudoaneurysm in a 54-year-old female patient diagnosed with breast cancer and lung metastasis. The patient underwent five intrapericardial infusions of cisplatin and nine cycles of systemic chemotherapy. Non-contrast-enhanced computed tomography (CT) was performed at follow-up evaluation during the chemotherapeutic process as this patient was contraindicated to iodine. CT without contrast and ultrasonography showed a crescent-shaped lesion near the right atrium but its nature could not be determined. Cardiac magnetic resonance (CMR) imaging with gadolinium contrast provided important information as an alternative enhanced imaging modality. By combining CT, ultrasonography and CMR images with the medical history of the patient, we inferred that the lesion was a pseudoaneurysm in the right atrium. This condition was related to the erosion of metastasized tumor cells or the accumulated cardiac toxicity of multiple cycles of chemotherapy or pericardiocentesis. This single case report suggests that cardiac rupture should be considered as a potential complication in patients with suspected pericardial metastasis. CMR imaging is an excellent tool for the detection of right atrial rupture.

Right ventricular free wall perforation during pericardiocentesis, and an inappropriate device selection for percutaneous treatment

Right ventricular (RV) perforation is a rare but life-threatening complication of pericardiocentesis and is usually treated surgically. We presented a case of RV free wall perforation, which occurred during pericardiocentesis and tried to be closed percutaneously with the Amplatzer vascular plug-III (AVP-III) device. The occluder device sealed the perforation, but it was in an insecure position; therefore, the patient underwent surgical repair. As an AVP-III device, with a middle disk thicker than the RV myocardium, it may cause the RV myocardium to stretch outwards, so it should not be used for the treatment of RV perforation by the transcatheter way.

Imaging Cardiovascular Emergencies: Real World Clinical Cases

Cardiovascular emergencies represent life-threatening conditions requiring a high index of clinical suspicion. In an emergency scenario, a simple stepwise biomarker/imaging diagnostic algorithm may help prompt diagnosis and timely treatment along with related improved outcomes. This article describes several clinical cases of cardiovascular emergencies, such as coronary stent thrombosis-restenosis, takotsubo syndrome, acute myocarditis, massive pulmonary embolism, type A acute aortic dissection, cardiac tamponade, and endocarditis.

Inadvertent ascending aortic perforation after transseptal puncture: Successful treatment with an Amplatzer Duct Occluder II device

Transseptal puncture is a routine technique to access the left atrium during catheter ablation, but carries a small risk of perforation into the pericardium or aorta. When conservative management fails, surgical repair is usually needed. We report an 81-year-old male in whom aortic root perforation occurred after transseptal puncture and was treated successfully by percutaneous deployment of an Amplatzer Duct Occluder II device.

Inpatient mortality and its predictors after pericardiocentesis: An analysis from the Nationwide Inpatient Sample 2009-2013

BACKGROUND

National registries have provided data on in-hospital outcomes for several cardiac procedures. The available data on in-hospital outcomes and its predictors after pericardiocentesis are mostly derived from single center studies. Furthermore, the outcomes after pericardiocentesis for iatrogenic pericardial effusion and the impact of procedural volume on in-hospital outcomes in the United States are largely unknown.

METHODS

We used national inpatient database files for the years 2009-2013 to estimate the inpatient outcomes after pericardiocentesis in all-comers and in the subgroups with iatrogenic effusion. We also studied the impact of hospital procedural volume, among other predictors, on inpatient mortality.

RESULTS

About 64,070 (95%CI 61 008-67 051) pericardiocentesis were performed in the United States during 2009-2013. Of these, 57.15% (56.02-58.26%) of the pericardiocentesis were in hemodynamically unstable patients. Percutaneous cardiac procedures were performed in 17.7% of patients (percutaneous coronary intervention (PCI) 4.02%, electrophysiologic procedures 13.58%, and structural heart intervention (SHI) 0.76%). Overall inpatient mortality was 12.30% (95%CI 11.66-12.96%). Inpatient mortality after PCI, electrophysiologic procedures, SHI and cardiac surgery were 27.67% (95%CI 24-31.67%), 7.8% (95%CI 6.67-9.31%), 22.36% (95%CI 15.06-31.85%) and 18.97% (95%CI 15.84-22.57%), respectively. There was an inverse association between hospital procedural volume and inpatient mortality, with a mortality of 14.01% (12.84-15.26%) at the lowest and 10.82% (9.44-12.37%) at highest quartile hospitals by procedure volume (p_trend = 0.001).

CONCLUSION

The inpatient mortality after pericardiocentesis is high, particularly when associated with PCI and SHI.

Incidence and Management of Hemopericardium: Impact of Changing Trends in Invasive Cardiology

OBJECTIVE

As invasive cardiovascular care has become increasingly complex, cardiac perforation leading to hemopericardium is a progressively prevalent complication. We sought to assess the frequency, etiology, and outcomes of hemorrhagic pericardial effusions managed through a nonsurgical echo-guided percutaneous strategy.

PATIENTS AND METHODS

Over a 10-year period (January 1, 2007, to December 31, 2016), 1097 unique patients required pericardiocentesis for clinically important pericardial effusions. Of these 411 had drainage of hemorrhagic effusions (defined as a pericardial hemoglobin level >50% of serum hemoglobin or frank blood in the setting of cardiac perforation). Clinical characteristics, echocardiographic data, details of the procedure, and outcomes were determined.

RESULTS

Median patient age was 67 years (interquartile range, 56-76 years), and 60% were men. The procedure was emergent in 83% and elective in 17%. The site of pericardiocentesis was determined by echo-guidance in all: 68% from the left para-apical region, 18% from the left or right parasternal areas, and 14% were subxyphoid. Half (n=215 [52%]) occurred after cardiac perforation with percutaneous interventional procedure (ablation, n=94; device lead implantation, n=65; percutaneous coronary intervention, n=22; other, n=34), whereas 30% followed cardiac or thoracic surgery. Pericardial fluid volume drained was 546±440 mL. In 94% of cases, echo-guided pericardiocentesis was the only treatment of the effusion needed, whereas definitive surgery was required in 25 (6%) cases for persistent bleeding or acute management of the underlying etiology. There was no procedural mortality. Late mortality was better for hemorrhagic effusions compared with a contemporary cohort with nonhemorrhagic effusions.

CONCLUSION

Echocardiographic guidance allows rapid successful pericardiocentesis in the setting of hemopericardium related to microperforation with interventional procedures, malignancy, or pericarditis, with most not requiring surgical intervention. Surgery should remain the first-line approach for aortic dissection or myocardial rupture.

Management of cardiac tamponade during catheter-directed thrombolysis of saddle pulmonary embolism: A clinical dilemma

Catheter-directed thrombolysis (CDT) for the treatment of acute pulmonary embolism (PE) has gained popularity in recent years, but potential complications during the procedure and their management are not frequently discussed in the literature. In this case report, we describe the clinical dilemma regarding the postoperative anticoagulation management of a 60-year-old male who developed cardiac perforation during a CDT of an acute saddle PE. Early resumption of systemic heparin in such cases may help in clot resolution; however, it can worsen the hemopericardium. On the other hand, delaying restarting heparin may help in healing of the cardiac perforation but can lead to clot propagation. As the chest tube output was minimal initially, anticoagulation was started, which, however, led to disastrous outcome. With limited published medical literature to help guide such a complex situation, it may be prudent to carefully weigh the risks and benefits of resuming systemic heparin versus delaying it for 1–2 days to allow for definitive resolution of the cardiac perforation.

A "Vanishing", Tuberculous, Pericardial Effusion

We present an iatrogenic, pleuro-pericardial connection resulting from pericardiocentesis of a large, tuberculous, pericardial effusion. Recognition of this situation is paramount when one is unable to aspirate pericardial fluid after a successful, initial puncture. Such knowledge will help prevent myocardial or coronary artery injury with further attempts at aspiration.

Novel, Long-axis In-plane Ultrasound-Guided Pericardiocentesis for Postoperative Pericardial Effusion Drainage

Pericardial effusion can be a life-threatening complication in children after cardiac surgery. Percutaneous pericardiocentesis is associated with rare, but serious complications. This retrospective study describes our experience with a novel, long-axis in-plane real-time ultrasound (US)-guided technique for postoperative pericardial effusion drainage in small children. Ten out of sixteen procedures were performed within 14 days of cardiac surgery at a median postoperative day 12 (IQR 2, 99). Median age was 2.7 months (IQR 0.4124) and weight 4.5 kg (IQR 2.5, 41.6). All but one procedure required a single attempt. Fourteen out of sixteen procedures had subxiphoid approach, and two were apical. Median initial drainage was 9 mL/kg (IQR 4.5, 27). Fifty percent of effusions were serous, 25 % chylous, and the remainder bloody. There were no reported complications. This study demonstrates a novel, long-axis pericardiocentesis technique that allows for an easy and safe needle entry into the pericardial space for small children in the early postoperative period.

[Progress or regress or both? ESC guidelines on pericardial diseases 2015]

Eleven years after the publication of the first guidelines worldwide on pericardial diseases by the European Society of Cardiology (ESC), the international expert group of the ESC has updated the original document of 28 pages with 275 references. The final version of the new guidelines is more voluminous with 44 pages of recommendations but only 233 references. A continuing medical education (CME) certified update of the 2004 guidelines was published in the journal Herz volume 7/2014. In comparison to 2004 the 2015 guidelines have remained virtually unchanged in the sections detailing diagnostics, differential diagnosis, pathology and pathophysiology. Substantial progress has been made in magnetic resonance imaging (MRI) of pericarditis and epicarditis and in the practically universal recommendation of colchicine for all forms of pericarditis and pericardial effusion, whether acute, chronic or recurrent. This can truly be called progress; however, little has changed since 2004 even in tertiary referral centers or universities with respect to the etiological classification of acute or recurrent forms of pericarditis or pericardial effusion. By classifying pericardial syndromes much too often as idiopathic when a malignant or bacterial cause has been excluded, the underlying cause is often overlooked. Standstill in diagnosis is in the end regress because we too often lag behind our actual diagnostic and interventional possibilities.

Management of Periprocedural and Early Pericardial Effusions With Tamponade Following Ablation of Atrial Fibrillation With Uninterrupted Factor Xa Inhibitors: A Case Series

INTRODUCTION

Because of the absence of a dedicated reversal agent, the outcome of pericardial effusion (PE) following procedures performed with uninterrupted apixaban or rivaroxaban is unknown. We report the characteristics of PEs presenting with tamponade in patients undergoing AF ablation with uninterrupted factor Xa inhibition (FXaI) to understand their management and prognosis.

METHODS AND RESULTS

We performed a multicenter cross-sectional survey in 10 centers across the United States. Patient data were obtained by chart review. In all patients the procedure was performed with uninterrupted FXaI. A total of 16 PEs requiring intervention were reported from 5 centers. Two patients were on apixaban 5 mg BD, the remaining on rivaroxaban 20 mg OD. Eleven PEs occurred in the periprocedural setting, and 5 PEs occurred from 1 to 28 days after the procedure. Pericardiocentesis and drainage were performed in all cases. Protamine and 4-factor prothrombin complex concentrate (4F-PCC) were given in all periprocedural cases. Two patients required surgery: in one case coagulation of the pericardial blood prevented effective drainage, and in the other bleeding was secondary to a steam pop-induced atrial tear. None of the postprocedural cases required FXaI reversal and the dose of rivaroxaban was temporarily reduced. No fatal outcomes or thromboembolic events were reported.

CONCLUSION

Pericardiocentesis and drainage with FXaI reversal proved effective in the management of acute PEs with tamponade occurring periprocedurally in patients undergoing AF ablation with uninterrupted FXaI. Early postprocedural effusions can be treated with pericardiocentesis without the need of a reversal agent.

Complications of pericardiocentesis: A clinical synopsis

Pericardiocentesis (PC) is both a diagnostic and a potentially life-saving therapeutic procedure. Currently echocardiography-guided pericardiocentesis is considered the standard clinical practice in the treatment of large pericardial effusions and cardiac tamponade. Although considered relatively safe, this invasive procedure may be associated with certain risks and potentially serious complications. This review provides a summary of pericardiocentesis and a focused overview of the potential complications of this procedure.

Transient acute left ventricular dysfunction post-pericardiocentesis for cardiac tamponade

A rare but serious complication of pericardiocentesis is the development of transient left ventricular dysfunction. In this report, we present a case of a 65-year-old male patient with cardiac tamponade who suffered from acute left ventricular heart failure post-pericardiocentesis. <Learning objective: Acute left ventricular dysfunction is a rare but serious complication of pericardiocentesis. However, there is lack of existing guidelines on pericardial fluid drainage and monitoring post-pericardiocentesis. To minimize the risk of the development of acute left ventricular dysfunction, the authors propose that every pericardiocentesis should be guided by predetermined parameters, e.g. rate of drainage, while taking into account each patient's physical profile.>.

[Diagnostics and therapy of pericarditis and pericardial effusion]

This article describes the diagnostics, differential diagnostics, multimodal imaging, medicinal and invasive diagnostic therapy of acute and chronic pericarditis, constrictive pericarditis, pericardial effusion and cardiac tamponade under etiological aspects and on the basis of the guidelines of the European Society of Cardiology (ESC). The starting point of the decision tree is the symptomatic patient with echocardiographic evidence of pericardial effusion. The principle feature of the diagnostics is the etiopathogenetic allocation of the pericardial disease which influences the clinical picture, course therapy and prognosis. Infectious pericarditis (e.g. viral, bacterial and tuberculous) is differentiated from sterile autoreactive pericarditis and from neoplastic pericardial effusion by the cytology of the effusion and immunohistological and molecular investigations of the pericardial and epicardial biopsies. Pericardioscopy plays an important role in the recognition of suspicious areas. In many cases intrapericardial administration of cisplatin for neoplastic pericardial effusion and instillation of triamcinolone for autoreactive pericarditis prevent recurrence just as a treatment of several months with colchicine.

Pericardiocentesis adverse event risk factors: a nationwide population-based cohort study

OBJECTIVES

Echocardiography-guided pericardiocentesis has been the leading procedure for diagnosis and therapy of pericardial effusion. We aimed to identify risk factors for recurrence, complications, and mortality in pericardial effusion patients treated with pericardiocentesis.

METHODS

We identified and collected data from 8,101 patients receiving pericardiocentesis between 1997 and 2010 from the Taiwan National Health Insurance Research Database. A multivariate regression model was used to investigate risk factors for recurrence, complications, and death.

RESULTS

There were 8,565 admissions among 8,101 patients. The most common underlying condition was malignancy (41%), especially lung cancer (23%), tuberculosis (9.0%), and acute pericarditis (8.2%). Surgical drainage was required in 12.7% of cases. Recurrence was more likely in patients with malignancy (HR 2.20, p < 0.001), but complications were less likely (OR 0.52, p = 0.003). In-hospital death numbers and complication risks (OR 2.38, p < 0.001; OR 1.27, p = 0.01) were greater in the catheter-related cardiac procedure group than in the other groups.

CONCLUSIONS

Malignant neoplasms and catheter-based cardiac procedures have become major risk factors for adverse events in patients receiving pericardiocentesis in Taiwan. Malignancy leads to an increase in recurrence and in-hospital mortality but is associated with a lower rate of acute complications. Cardiac catheterization procedures and surgery increase both complications and in-hospital mortality.

European Association of Cardiovascular Imaging (EACVI) position paper: Multimodality imaging in pericardial disease

Although pericardial diseases are common in the daily clinical practice and can result in a significant morbidity and mortality, imaging of patients with suspected or known pericardial disorders remain challenging. Multimodality imaging is part of the management of pericardial diseases. Echocardiography, cardiac computed tomography, and cardiovascular magnetic resonance are often used as complementary imaging modalities. The choice of one or multiple imaging modalities is driven by the clinical context or conditions of the patient. The scope of the present document is to highlight the respective role of each technique according to the clinical context in the diagnosis and management of pericardial diseases.

Etiology and characteristics of large symptomatic pericardial effusion in a community hospital in the contemporary era

BACKGROUND

The etiology and laboratory characteristics of large symptomatic pericardial effusion (LSPE) in the Western world have evolved over the years, and vary between regions, community and tertiary hospitals.

METHODS

We reviewed data of 86 consecutive patients who underwent pericardiocentesis or pericardial window due to LSPE in a community hospital from 2001 to 2010. The characteristics of the PE including chemistry, hematology, bacteriology, serology and cytology have been analyzed. We correlated the etiologies of PE with age, gender and clinical presentation.

RESULTS

The most frequent etiology of LSPE was idiopathic [36% (77% with a clinical diagnosis of pericarditis)], followed by malignancy (31.4%), ischemic heart disease (16.3%), renal failure (4.6%), trauma (4.6%) and autoimmune disease (4.6%). The average age of all the etiological groups excluding trauma was over 50 years. Laboratory tests did not modify the pre-procedure diagnosis in any of the patients. The most frequent presenting symptom was dyspnea (76.6%). Chest pain was mostly common in patients with idiopathic etiology (58.06%). The most frequent medical condition associated with LSPE was the use of anticoagulant or antiplatelet drugs (31.40%), especially aspirin, and in those, the PE tended to be bloody (73%, P = 0.11). Most of the effusions were exudates (70.9%). PE due to renal failure was the largest (1467 ± 1387 ml).

CONCLUSION

The spectrum of etiologies of LSPE in a community hospital in the Western world in the contemporary era is continuously evolving. The most frequent etiology is now idiopathic, followed by malignancy. Routine laboratory testing still rarely modifies the pre-procedure diagnosis.

Advanced ultrasound procedures

Ultrasound guidance has become the standard of care for many bedside procedures, owing to its portability, ease of use, and significant reduction in complications. This article serves as an introduction to the use of ultrasonography in several advanced procedures, including pericardiocentesis, thoracentesis, paracentesis, lumbar puncture, regional anesthesia, and peritonsillar abscess drainage.

Echocardiographic guidance for diagnostic and therapeutic percutaneous procedures

Echocardiographic guidance has an important role in percutaneous cardiovascular procedures and vascular access. The advantages include real time imaging, portability, and availability, which make it an effective imaging modality. This article will review the role of echocardiographic guidance for diagnostic and therapeutic percutaneous procedures, specifically, transvenous and transarterial access, pericardiocentesis, endomyocardial biopsy, transcatheter pulmonary valve replacement, pulmonary valve repair, transcatheter aortic valve implantation, and percutaneous mitral valve repair. We will address the ways in which echocardiographic guidance provides these procedures with detailed information on anatomy, adjacent structures, and intraprocedural instrument position, thus resulting in improvement in procedural efficacy, safety and patient outcomes.

Assessment of a low-cost ultrasound pericardiocentesis model

Introduction. The use of ultrasound during resuscitation is emphasized in the latest European resuscitation council guidelines of 2013 to identify treatable conditions such as pericardial tamponade. The recommended standard treatment of tamponade in various guidelines is pericardiocentesis. As ultrasound guidance lowers the complication rates and increases the patient's safety, pericardiocentesis should be performed under ultrasound guidance. Acute care physicians actually need to train emergency pericardiocentesis. Methods. We describe in detail a pericardiocentesis ultrasound model, using materials at a cost of about 60 euros. During training courses of focused echocardiography n = 67, participants tested the phantom and completed a 16-item questionnaire, assessing the model using a visual analogue scale (VAS). Results. Eleven of fourteen questions were answered with a mean VAS score higher than 60% and thus regarded as showing the strengths of the model. Unrealistically outer appearance and heart shape were rated as weakness of the model. A total mean VAS score of all questions of 63% showed that participants gained confidence for further interventions. Conclusions. Our low-cost pericardiocentesis model, which can be easily constructed, may serve as an effective training tool of ultrasound-guided pericardiocentesis for acute and critical care physicians.

Atypical complications encountered with epicardial electrophysiological procedures

BACKGROUND

With the increasing use, complexity, anatomical approaches, and tools related to epicardial procedures, complications previously not seen during endovascular ablation are now well recognized with epicardial ablation. Whether newer approaches and the regional anatomy of the pericardial space contribute to unexpected complications after epicardial access (EpiAcc) is presently unknown.

OBJECTIVE

To characterize underreported, or novel, complications associated with percutaneous EpiAcc as part of an electrophysiology procedure.

METHODS

We retrospectively reviewed percutaneous EpiAcc as part of an ablation procedure from January 1, 2004, to December 31, 2011.

RESULTS

Of 116 attempts in 107 patients, 8 atypical ablation complications (no procedural deaths) were noted; complications included delayed pericarditis (2 weeks), chronic refractory pericarditis, requirement for snaring of broken intrapericardial wire, pleural perforation, phrenic nerve injury despite protective strategies, hemoperitoneum, and abdominal-pericardial fistula.

CONCLUSION

Vigilance both during and after EpiAcc is needed to recognize these complications, some of which may be life-threatening.

Real-time cardiovascular magnetic resonance subxiphoid pericardial access and pericardiocentesis using off-the-shelf devices in swine

BACKGROUND

Needle access or drainage of pericardial effusion, especially when small, entails risk of bystander tissue injury or operator uncertainty about proposed trajectories. Cardiovascular magnetic resonance (CMR) might allow enhanced imaging guidance.

METHODS AND RESULTS

We used real-time CMR to guide subxiphoid pericardial access in naïve swine using commercial 18G titanium puncture needles, which were exchanged for pericardial catheters. To test the value of CMR needle pericardiocentesis, we also created intentional pericardial effusions of a range of volumes, via a separate transvenous-transatrial catheter. We performed these procedures in 12 animals.

CONCLUSIONS

CMR guided pericardiocentesis is attractive because the large field of view and soft tissue imaging depict global anatomic context in arbitrary planes, and allow the operator to plan trajectories that limit inadvertent bystander tissue injury. More important, CMR provides continuous visualization of the needle and target throughout the procedure. Using even passive needle devices, CMR enabled rapid pericardial needle access and drainage. We believe this experience supports clinical testing of real-time CMR guided needle access or drainage of the pericardial space. We suspect this would be especially helpful in "difficult" pericardial access, for example, in distorted thoracic anatomy or loculated effusion.

An extremely rare combination: pneumopericardium, pneumoperitoneum, and subcutanous emphysema-a case report

Pneumopericardium, an accumulation of air in the pericardial cavity, occurs very rarely as compared to pneumothorax and pneumomediastinum. Clinical presentation is variable, patients are frequently asymptomatic, and mild cases usually resolve spontaneously. However, it may lead to pericardial tamponade, which requires rapid diagnosis and treatment that can be lifesaving. The traditional diagnostic, simple method of diagnosis is via an upright chest X-ray. Typical findings can be detected and a differential diagnosis can be made between pneumomediastinum and pneumopericardium. Echocardiography and chest computed tomography scans can also support the diagnosis. Only one case of pneumopericardium after surgical pericardiotomy has been reported in the literature so far. In this case report, iatrogenic pneumopericardium, which resolved spontaneously after surgical pericardiotomy, was reported in a 19-year-old patient who had a rejected liver transplantation, and had liver and kidney failure with pericardial tamponade. In this case, pneumopericardium was accompanied by pneumoperitoneum and subcutaneous emphysema; an extremely rare combination.

Immediate rescue operations after failed diagnostic or therapeutic cardiac catheterization procedures

OBJECTIVES

Although rare, life-threatening complications requiring emergency cardiac surgery do occur after diagnostic and therapeutic cardiac catheterization procedures. The operative mortality has been persistently reported to remain high. The purpose of this observational study was to evaluate and report the outcomes, with particular emphasis on early mortality, of these risky operations that were performed in a single highly specialized cardiac centre.

METHODS

Between June 1997 and August 2007, 100 consecutive patients, 13 after diagnostic complicated cardiac catheterization (0.038% of 34,193 angiographies) and 87 after crashed percutaneous coronary intervention (PCI; 0.56% of 15,544 PCIs), received emergency operations at the Feiring Heart Center. In the same period, 10,192 other patients underwent open cardiac surgery. Early outcome data were analysed and compared between the cohorts. Follow-up was 100% complete.

RESULTS

The preoperative status of the 100 patients was that 4 had ongoing external cardiac massage, 24 were in cardiogenic shock, 32 had frank enduring ST-segment infarction but without shock and 40 had threatened acute myocardial infarction. There was 1% (1 patient) 30-day mortality in the study group, which is equal (0.9%, P=0.60) to that of all other operations. Postoperative myocardial infarction and prolonged ventilator use were significantly higher in the crash group, whereas the rate of stroke, renal failure, reopening for bleeding and mediastinitis were similar between the groups.

CONCLUSIONS

With rapid transfer to an operation room, minimizing the time of warm myocardial ischaemia, and by performing complete coronary revascularization, it is possible to obtain equally low operative mortality in patients with life-threatening cardiac catheterization-associated complications, as is the case with open cardiac operations in general.

Pericardial effusion and pericardiocentesis: role of echocardiography

Pericardial effusion can develop from any pericardial disease, including pericarditis and several systemic disorders, such as malignancies, pulmonary tuberculosis, chronic renal failure, thyroid diseases, and autoimmune diseases. The causes of large pericardial effusion requiring invasive pericardiocentesis may vary according to the time, country, and hospital. Transthoracic echocardiography is the most important tool for diagnosis, grading, the pericardiocentesis procedure, and follow up of pericardial effusion. Cardiac tamponade is a kind of cardiogenic shock and medical emergency. Clinicians should understand the tamponade physiology, especially because it can develop without large pericardial effusion. In addition, clinicians should correlate the echocardiographic findings of tamponade, such as right ventricular collapse, right atrial collapse, and respiratory variation of mitral and tricuspid flow, with clinical signs of clinical tamponade, such as hypotension or pulsus paradoxus. Percutaneous pericardiocentesis has been the most useful procedure in many cases of large pericardial effusion, cardiac tamponade, or pericardial effusion of unknown etiology. The procedure should be performed with the guidance of echocardiography.

Management of Cardiac Tamponade: A Comperative Study between Echo-Guided Pericardiocentesis and Surgery-A Report of 100 Patients

Background. Cardiac tamponade (CT) represents a life-threatening condition, and the optimal method of draining accumulated pericardial fluid remains controversial. We have reviewed 100 patients with CT at our institution over a five-year period and compared the results of echo-guided pericardiocentesis, primary surgical treatment, and surgical treatment following pericardiocentesis with regard to functional outcomes. Methods. The study group consisted of 100 patients with CT attending Yuzuncu Yil University from January 2005 to January 2010 who underwent one of the 3 treatment options (echo-guided pericardiocentesis, primary surgical treatment, and surgical treatment following pericardiocentesis). CT was defined by clinical and echocardiographic criteria. Data on medical history, characteristics of the pericardial fluid, treatment strategy, and follow-up data were collected. Results. Echo-guided pericardiocentesis was performed in 38 (38%) patients (Group A), primary surgical treatment was preformed in 36 (36%) patients (Group B), and surgical treatment following pericardiocentesis was performed in 26 (26%) patients (Group C). Idiopathic and malignant diseases were primary cause of tamponade (28% and 28%, resp.), followed by tuberculosis (14%). Total complication rates, 30-day mortality, and total mortality rates were highest in Group C. Recurrence of tamponade before 90 days was highest in Group A. Conclusions. According to our results, minimal invasive procedure echo-guided pericardiocentesis should be the first choice because of lower complication and mortality rates especially in idiopathic cases and in patients with hemodynamic instability. Surgical approach might be performed for traumatic cases, purulent, recurrent, or malign effusions with higher complication and mortality rates.
