Contemporary outcomes after pericardial window surgery: impact of operative technique

Transthoracic Color Doppler Ultrasound-Guided Grooved Negative Pressure Drainage Tube Implantation in Pericardial Effusion After Cardiac Surgery

INTRODUCTION

Pericardial effusion is a common complication without a standard postoperative effusion treatment after cardiac surgery. The grooved negative pressure drainage tube has many advantages as the emerging alternative for drainage of pericardial effusion, such as it changes the structure of the traditional side hole, uses the capillary function to ensure drainage smooth, etc. The purpose of this study was to assess the feasibility and effectiveness of transthoracic color Doppler ultrasound-guided grooved negative pressure drainage tube implantation in pericardial effusion after cardiac surgery.

METHODS

All patients with pericardial effusion after cardiac surgery who underwent transthoracic color Doppler ultrasound-guided grooved negative pressure drainage tube implantation between January 2019 and December 2021 were retrospectively analyzed. Treatment results (including clinical symptoms, effusion volume, color Doppler ultrasonography, and computed tomography scan) were investigated to evaluate the effectiveness and safety of this method.

RESULTS

A total of 20 patients successfully underwent transthoracic color Doppler ultrasound-guided grooved negative pressure drainage tube implantation. After the operation, their symptoms (chest tightness, shortness of breath, etc.) were all relieved, and dark red or light red drainage fluid (> 200 ml) appeared in the newly placed drainage bottle. Color Doppler ultrasonography showed that the volume of pericardial effusion decreased significantly.

CONCLUSION

The transthoracic color Doppler ultrasound-guided grooved negative pressure drainage tube is a safe and effective method for the treatment of postoperative pericardial effusion with less trauma, faster recovery, shorter in-hospital stay, and fewer complications.

Awake uniportal video-assisted thoracoscopic surgery for the management of pericardial effusion

Introduction

Pericardial drainage can be performed either with pericardiocentesis or pericardial "window" in cases with hemodynamic compromise for therapeutic and diagnostic purposes. Awake single-port video-assisted thoracoscopic surgery (VATS) is an alternative to pericardial window (PW) that has been described only in case reports in the literature. We aimed to analyse a series of patients with chronic, recurrent and/or large pericardial effusions who underwent single-port VATS-PW opening without intubation.

Patients and Methods

The PW was opened using awake single-port VATS in 20 of 23 patients referred to our clinic with recurrent, chronic and/or large pericardial effusion between December 2021 and July 2022. Demographic data, imaging modalities, treatment processes and pathological samples were analysed retrospectively.

Results

The median age of 20 patients was 68 years (52-81). The mean body mass index was 29.1 ± 6.0 kg/m2 and mean pericardial fluid measurements with pre-operative transthoracic echocardiography (TTE) was 2,8 ± 0,9 cm. The mean operation time was 44 ± 13.0 min and mean peri-operative drainage was 700 ± 307 cc. On the 1st post-operative day, control TTE revealed ≤0.5 cm effusion in 18 (90%) patients and ≥0.5 cm in 2 (10%) patients. The median day of discharge or referral to the clinic where they are followed up was 1 (1-2).

Conclusions

Awake single-port VATS could be used safely in all patient groups with pericardial effusion or tamponade as a diagnostic and therapeutic option. This technique has advantages, especially in patients with high surgical risk.

COVID-19-Induced Cardiac Tamponade: A Case Study and a Literature Review

COVID-19 presentation is heterogeneous. As a viral illness, it could cause pericardial effusion leading to cardiac tamponade. We present a patient coursing with this viral illness that was found to have cardiac tamponade. We report a case of a 79-year-old female who presented with shortness of breath and dry cough for one week and resulted positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Her initial chest X-ray showed a bottle-shaped heart. Computed chest tomography showed pericardial effusion, and an echocardiogram confirmed moderated pericardial effusion with signs of tamponade. He improved with conservative therapy with colchicine, ibuprofen, cefepime, dexamethasone, dolutegravir, and apixaban for pulmonary emboli. An early approach in cardiac tamponade induced by COVID-19 is crucial to promptly address an aggressive directed therapy, avoiding potential complications or unnecessary procedures.

Percutaneous balloon pericardiotomy: efficacy in a series of malignant and nonmalignant cases

OBJECTIVE

In the case of malignant pericardial effusion and cardiac tamponade, balloon pericardiotomy is an established minimally invasive option to the surgical creation of a subxiphoid pericardial window. Percutaneous balloon pericardiotomy effectively drains recurrent pericardial fluid by creating a pleuro (-abdominal-) pericardial communication. Design. A series of 26 patients with underlying malignant (n = 12) and nonmalignant (n = 14) diseases underwent percutaneous balloon pericardiotomy between 2008 and 2021. All interventions were done through a subxiphoid access under local anesthesia. Results. The mean survival in the malignant and nonmalignant groups was 1.2 versus 48.0 months, respectively (p < .001). There were neither severe periinterventional complications nor in-hospital deaths. In two patients with nonmalignant disease the surgical creation of a pericardial window was necessary during follow-up. The originally described procedure was modified by the removal of all catheters at the end of the intervention. The procedure was safe. It prevented immobility and facilitated an early discharge from the hospital. Conclusion. Our experiences show that percutaneous balloon pericardiotomy is a minimally invasive approach to successfully provide palliation in the group of patients with underlying malignant disease. On the other hand, we have shown that this technique is safe and feasible in the treatment of pericardial effusion based on nonmalignant disease. We think thereby that pericardial balloon pericardiotomy can be considered as a less invasive alternative to surgery in both groups of patients.

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.

Video-Assisted Thoracoscopic Surgery Management of Subacute Retained Blood Syndrome after Cardiac Surgery

PURPOSE

Blood loss along with inadequate evacuation after cardiac surgery leads to retained blood syndrome (RBS) in the pleural and/or pericardial cavity. Re-sternotomy is often needed for clot evacuation. Video-assisted thoracoscopic surgery (VATS) evacuation is a less-invasive procedure. However, sufficient evidence on safety and outcomes is lacking.

METHODS

Thirty patients who developed hemothorax and/or hemopericardium after cardiac surgery and underwent VATS evacuation between April 2015 and September 2020 were included in this retrospective single-center analysis.

RESULTS

The median patient age was 70 (interquartile range: IQR 62-75) years, body mass index (BMI) was 24.7 (IQR 22.8-29) kg/m2, time between initial cardiac surgery and VATS was 17 (IQR 11-21) days, 30% of the patients were female, 60% resided in the ICU, and 17% were nicotine users. Coronary artery bypass graft was the most frequent initial cardiac procedure. Median operation time was 120 (IQR 90-143) min, 23% of the patients needed an additional VATS, and the median length of hospital stay after VATS was 8 (IQR 5-14) days. All patients survived VATS, and we experienced no mortality related to the VATS procedure.

CONCLUSION

In our study, VATS for evacuation of RBS after cardiac surgery was a feasible, safe, and efficient alternative approach to re-sternotomy in selected patients.

Pericardiocentesis in children: 20-year experience at a tertiary children's hospital

BACKGROUND

Pericardiocentesis is the invasive percutaneous procedure for acute and chronic excessive accumulation of pericardial fluid. There is a paucity of data on the effectiveness and safety of pericardiocentesis in children.

OBJECTIVES

To evaluate the effectiveness and safety of pericardiocentesis and factors associated with acute procedural failure and adverse events.

METHODS

This was a single-centered retrospective study to describe all the children aged ≤20 years who underwent pericardiocentesis. Data on demographics, etiologies of pericardial effusion, and repeat intervention at follow-up were collected.

RESULTS

A total of 127 patients underwent 153 pericardiocentesis. The median age was 6.5 years (1 day-20 years) with weight of 17 kg (0.5-125). Most common etiology was post-pericardiotomy syndrome (n = 56, 44%), followed by infectious (12%), malignant (10%), and iatrogenic (9%). Pericardiocentesis was performed more commonly in the catheterisation laboratory (n = 86, 59%). Concurrent pericardial drain placement was performed in 67 patients (53%). Acute procedural success was 92% (141/153). Repeat intervention was performed in 33 patients (22%). The incidence of adverse events was 4.6% (7/153): hemopericardium requiring emergent surgery (n = 2); hemopericardium with hypotension (n = 2); seizure with anesthesia induction (n = 1); and right ventricle puncture with needle (n = 2). Pericardiocentesis at the bedside had a higher rate of acute procedural failure than that in the catheterisation lab (17 versus 1%, p < 0.01). No identifiable risk factors were associated with adverse events.

CONCLUSIONS

Pericardiocentesis was life-saving in children with its high effectiveness and safety even in urgent situations. Although initial pericardiocentesis was effective, one of five patients required re-intervention for recurrent pericardial effusion.

Where Did the Pericardial Effusion Go? A Case of Cardiopulmonary Resuscitation Acting as Treatment for Pericardial Tamponade

Pericardial tamponade results in multiple organ dysfunction and can lead to cardiac arrest. Cardiopulmonary resuscitation (CPR), a life-saving measure performed on patients in cardiac arrest, can lead to thoracic organ damage. However, CPR rarely acts as a therapeutic treatment for pericardial tamponade. Our case describes a patient admitted with pericardial tamponade in whom CPR provided therapeutic treatment with pericardial rupture and resolution of the tamponade.

Laparoscopic transdiaphragmatic pericardial fenestration in palliative care: how I do it

BACKGROUND

The optimal therapeutic strategy for drainage of malignant pericardial effusion is not yet determined. Several techniques are described, with different benefits and disadvantages. The literature suggests that surgical drainage of pericardial effusions has less effusion recurrence; however, randomized controlled trials are not available. Due to the nature of the disease, quality of life should always be considered while making treatment decisions.

METHODS

A retrospective analysis of all consecutive patients from November 2016 until June 2019 of our institution in the Netherlands was performed. All patients underwent laparoscopic pericardial fenestration after echocardiography and request for operative treatment by the cardiologist. The same operation technique was performed in every case.

RESULTS

Four out of five of our patients needed pericardial fenestration because of oncological diseases. No hemodynamically instability was noted during this fast technique, achieving direct relief of symptoms. No treatment-related morbidity or mortality, nor the need for re-intervention was encountered. We compared the outcome of our five patients with the existing evidence in the literature.

CONCLUSIONS

In this article, we highlight the laparoscopic transdiaphragmatic pericardial fenestration as a treatment of preference in a non-acute palliative setting. This laparoscopic approach is safe, and can be a valuable alternative among the other well-known approaches.

Rare complication after pericardial window: symptomatic diaphragmatic hernia containing bowel and liver

A 37-year-old woman presented to her local district general hospital with a cough, pleuritic chest pain and intermittent cyanosis. Eight months prior, she underwent a successful pericardial window for recurrent, symptomatic pericardial effusions. On presentation she was hypoxic but haemodynamically stable. Her chest radiograph raised the suspicion of a diaphragmatic hernia, confirmed by CT imaging. This identified herniation through the diaphragm of the transverse colon and left lobe of the liver resulting in cardiac compression and right ventricular dysfunction. She continued to deteriorate and required emergency intubation to allow safe transfer to a tertiary upper gastrointestinal unit. She underwent a laparotomy and repair of the diaphragmatic hernia with an uneventful inpatient recovery. In the literature, diaphragmatic liver herniation is a recognised complication secondary to trauma or congenital defects, however, to our knowledge, there are currently no cases described following pericardial windowing.

Long-Term Outcome of Pericardial Drainage in Cases of Chronic, Large, Hemodynamically Insignificant, C-Reactive Protein Negative, Idiopathic Pericardial Effusions

Pericardial effusion (PE) prognosis depends on the underlying etiology. We sought to assess the outcome of patients with chronic (>3 months), large (diastolic echo-free space >2 cm), idiopathic (without apparent etiology), C-reactive protein (CRP) negative PE, a topic where data are lacking. A total of n = 74 patients were enrolled in this study. Patients were treated by pericardiocentesis (n = 39) or surgical pericardial "window" (PW) (n = 13) or conservatively (n = 22). The median follow-up was 24 months (interquartile range: 15 to 38). Among those patients who had PE drained (n = 52), PE re-accumulation occurred in 32 cases (61.5%) and the rate was significantly higher in the pericardiocentesis subgroup (76.9% for pericardiocentesis vs 15.4% for PW group, p <0.001). Patients with re-accumulation had longer disease duration (32.1 ± 25.7 months vs 19.5 ± 23.8 months, p = 0.01), higher maximum PE diameter (32.2 ± 9.4 mm vs 26.1 ± 4.9 mm, p = 0.003) and larger PE volume drained at baseline (1,912 ± 707 mL vs 1,508 ± 387 mL, p = 0.04). Large PE re-accumulation occurred in 41% of patients who underwent pericardiocentesis and in 7.7% of those who underwent PW. In Cox survival analysis the only independent predictor of fluid re-accumulation was the type of intervention, with PW being associated with significantly reduced risk (hazard ratio 0.115, 95% confidence interval 0.015 to 0.875, p = 0.037). Major complications needing treatment were recorded in 12.8% and 15.4% (p = 0.999) of patients who underwent pericardiocentesis and PW, respectively. Moreover, invasive procedures were not helpful in establishing new diagnoses and guide treatment. In conclusion, in asymptomatic patients with chronic, large, hemodynamically insignificant, CRP negative, idiopathic PE, conservative management seems a more reasonable approach in most cases.

Mid-Term Efficacy of Subxiphoid Versus Transpleural Pericardial Window for Pericardial Effusion

BACKGROUND

The optimal surgical technique for drainage of pericardial effusions is frequently debated. Transpleural drainage via thoracotomy or thoracoscopy is hypothesized to provide more durable freedom from recurrent pericardial effusion than a subxiphoid pericardial window. We sought to compare operative outcomes and mid-term freedom from recurrent effusion between both approaches in patients with nontraumatic pericardial effusions.

METHODS

All patients at our institution who underwent a pericardial window from 2001 to 2018 were identified. After excluding those who underwent recent cardiothoracic surgery or trauma, patients (n = 46) were stratified by surgical approach and presence of malignancy. Primary outcome was freedom from recurrent moderate or greater pericardial effusion. Secondary outcomes included operative mortality and morbidity and mid-term survival. Follow-up was determined by medical record review, with a follow-up of 67 patient-years. Fisher's exact test and Wilcoxon rank-sum test were used to compare groups. Mid-term survival and freedom from effusion recurrence were determined using Kaplan-Meier method.

RESULTS

Subxiphoid windows (n = 31; 67%) were more frequently performed than transpleural windows (n = 15; 33%) and baseline characteristics were similar. Effusion etiologies included malignancy (n = 22; 48%), idiopathic (n = 12; 26%), uremia (n = 8; 17%), and collagen vascular disease (n = 4; 9%). Perioperative outcomes were comparable between the two surgical approaches, except for longer drain duration (7 versus 4 d, P = 0.029) in the subxiphoid group. Operative mortality was 19.6% overall and 36.4% in patients with malignancy. Mid-term survival and freedom from moderate or greater pericardial effusion recurrence was 37% (95% confidence interval [CI]: 19%-54%) and 69% (95% CI: 52%-86%) at 5 y, respectively. There was no difference in mid-term survival (P = 0.90) or freedom from pericardial effusion recurrence (P = 0.70) between surgical approaches. Although malignant etiology had worse late survival (P < 0.01), freedom from effusion recurrence was similar to nonmalignant etiology (P = 0.70).

CONCLUSIONS

Pericardial window provides effective mid-term relief of pericardial effusion. Subxiphoid and transpleural windows are equivalent in mid-term efficacy and both surgical approaches can be considered. Patients with malignancy have acceptable operative mortality with low incidence of recurrent effusion, supporting palliative indications.

Pericardial effusion with tamponade: bedside ultrasonography saves another life

In these video clinical images, the authors present the cause for an elderly gentleman’s shortness of breath. It was presumed to be an exacerbation of chronic obstructive pulmonary disease, a condition for which he was in the process of being evaluated. However, bedside ultrasonography revealed a large pericardial effusion with tamponade. This timely diagnosis resulted in the patient being taken expeditiously to the operating room and saving his life.

Evolution of the pericardiocentesis technique

: Pericardiocentesis is a valuable technique for the diagnosis and treatment of patients with pericardial effusion and cardiac tamponade, although it may be associated with potentially serious complications. Through the years, many different imaging approaches have been described to reduce the complication rate of the procedure. This systematic review provides a focused overview of the different techniques developed in recent years to reduce the procedural complications and to increase the related success rate.

Pericardial Disease Associated with Malignancy

PURPOSE OF REVIEW

Pericardial effusion is commonly associated with malignancy. The goals of treatment should include optimizing symptom relief, minimizing repeat interventions, and restoring as much functional status as possible.

RECENT FINDINGS

Pericardiocentesis should be the first intervention but has high recurrence rates (30-60%). For patients with recurrence, repeat pericardiocentesis is indicated in those with limited expected lifespans. Extended pericardial drainage decreases recurrence to 10-20%. The addition of sclerosing agents decreases recurrence slightly but creates significant pain and can lead to pericardial constriction and therefore has fallen out of favor. Most patients with symptomatic pericardial disease have a short median survival time due to their underlying disease. In patients with a longer life expectancy, surgical drainage offers the lowest recurrence rate. Surgical approach is based on effusion location and clinical condition. Subxiphoid and thoracoscopic approaches lead to similar outcomes. Thoracotomy should be avoided as it increases morbidity without improving outcomes.

Case report of refractory pericardial effusion associated with lymphatic fistula due to surgical injury during sternotomy

RATIONALE

A 35-year old Chinese female was admitted to hospital with refractory pericardial effusions 10 days post mitral valve replacement via median sternotomy. We performed an exploratory resternotomy and found lymphatic leakage on the surface of the diaphragm which was continuously emitting a light yellow fluid.

PATIENT CONCERNS

The patient complained of no obvious discomfort except for the concern of massive pericardial effusion drainage.

DIAGNOSES

Exploratory resternotomy and biochemical testing lead to a supradiaphragmatic lymphatic fistula being diagnosed as the cause of the refractory pericardial effusion.

INTERVENTIONS

The fistula was closed with a continuous suture and no other fistulas were found after a thorough exploration.

OUTCOMES

The patient was discharged home on postoperative day 5 and recovery was uneventful.

LESSONS

In this case a timely exploratory resternotomy proved effective in seeking the cause of and treating pericardial effusion following cardiac surgery.

Massive Hemorrhagic Pericardial Effusion With Cardiac Tamponade as Initial Manifestation of Mixed Connective Tissue Disease

Mixed connective tissue disease (MCTD) is a distinct entity of connective tissue disorders characterized by overlapping clinical features of various autoimmune diseases along with the presence of antibodies to ribonucleoprotein (anti-RNP). The prevalence of cardiac involvement in MCTD varies from 13% to 65% and accounts for approximately 20% of MCTD related mortality. In this case, we describe an elderly female patient with multiple complaints without a clear etiology on presentation. Echocardiogram revealed severe rapidly accumulating pericardial effusion causing tamponade necessitating pericardial window. Laboratory investigations showed positive ribonucleoprotein antibodies. Biopsy of pericardial tissue revealed fibrinous pericarditis. While pericarditis is commonly associated with MCTD, pericardial tamponade on the other hand is rarely described. This case highlights a very rare complication of the disease. Early recognition, prompt treatment, and regular follow-up with serial echo are essential for treatment.

Single-Port Thoracoscopic Pericardial Window Under Local Anesthesia

There are numerous surgical approaches for the treatment of pericardial effusions but no clear consensus of best management. We present a 44-year-old woman with metastatic breast cancer presenting with a new 2-cm pericardial effusion on ultrasound. In light of the patient's palliative condition and the urgent need for chemotherapy, careful consideration was made for her surgical drainage of the pericardial effusion. Because of the patient's medical comorbidities, a general anesthetic was deemed not to be in the patient's best interest. Furthermore, the invasive subxiphoid or thoracotomy approach for a pericardial window would have risked delaying her much needed chemotherapy. A single-port thoracoscopic pericardial window was performed under light sedation, ventilating spontaneously on supplementary oxygen through nasal cannula only. The patient was positioned in a supine position, and a single 8-mm port was inserted into the left hemithorax at the 5th intercostal space, midaxillary line under local anesthetic, and a pericardial window made. This minimally invasive approach, without the need for intubation or ventilation, allowed for rapid relief of symptoms and discharge for the patient to begin her chemotherapy in a timely manner. By undergoing the procedure awake and through a single port, the patient was discharged after a short inpatient stay. This novel approach can be advocated for patients where a general anesthetic or invasive surgical procedure is not suitable in the treatment of their pericardial effusion.

Prevention of cardiac herniation and left artery descending obstruction in cases of extensive surgical pericardial window procedure

The thoracotomy approach for pericardial window surgery was shown to be more effective at preventing effusion recurrence and the need for repeat surgery. However, cardiac herniation remains a common complication after extensive pericardial excision. This technical note describes a simple and effective technique to prevent potential heart herniation through the pericardial window and at the same time to avoid potential obstruction of the left artery descending.

Surgical Management of Pericardial Diseases

Disease of the pericardium represents a relatively rare indication for cardiac surgery, and there exist no widely accepted guidelines for surgical management. As such, the surgical approach to the pericardium has relied largely on institutional experience with a slow evolution based on published studies. In particular, management of pericardial constriction has varied widely from surgeon to surgeon and institution to institution, in large part due to a perception of inherent high risk to the procedure. This review covers the current practice of surgery for disease of the pericardium, with particular focus on the evolution of indications for pericardiectomy, new applications in inflammatory or relapsing pericarditis, and the progressive refinement in surgical technique and operative planning which have led to significantly improved outcomes in experienced centers.
