Case Presentation: A 63-year-old female presented to our emergency department with altered mental status and hypotension. She was transferred from the outpatient interventional radiology suite after becoming unresponsive during the removal of an inferior vena cava filter. The patient arrived somnolent with no other history available. Her physical exam was unremarkable. We used point-of-care-ultrasound to perform a rapid ultrasound for shock and hypotension (RUSH) exam. A large pericardial effusion along with signs of cardiac tamponade were identified. The cardiothoracic surgery team was notified, and the patient was taken to the operating room where pericardial blood and a large hematoma were evacuated. She recovered uneventfully and was discharged one week later.Discussion: The above case describes a very unstable patient whose diagnosis was obtained using the RUSH exam. History and physical did not point to a clear etiology. Options were very limited. She was too unstable to go for computed tomography, and other tests such as electrocardiogram, chest radiograph, and lab work would have been non-diagnostic. It was only after the cardiac view of the RUSH exam was obtained that a pericardial effusion and developing tamponade were identified, facilitating timely management. The RUSH exam, like the extended focused assessment with sonography for trauma, is used to help determine pathologies that need immediate intervention. Incorporation in the evaluation of critically ill patients reduces the time to diagnosis. Our case is a unique example of how point-of-care ultrasound can be used to urgently identify a life-threatening pathology.

Chest pain is a common presentation to the emergency department (ED) that can be caused by a multitude of etiologies. It can be challenging to differentiate life-threatening conditions from more benign causes. A 54-year-old woman presented to the ED complaining of chest pain with dyspnea in the setting of recent blunt trauma. This case offers a thorough yet practical approach to the diagnostic workup of chest pain with dyspnea in the ED setting. The surprising final diagnosis and case outcome are then revealed.

BACKGROUND: Acute pericarditis is often caused by viral infections, autoimmune diseases, and radiation therapy (RT). Infectious pericarditis is rare and associated with high morbidity and mortality. We present a case of acute RT-induced pericarditis complicated by bacterial pericarditis and cardiac tamponade due to oesophageal bacterial translocation. CASE SUMMARY: A 65-year-old man with a recurrent mediastinal sarcoma complicated by oesophageal compression and recent oesophageal stenting presented with shortness of breath. Electrocardiogram showed diffuse ST elevations, and he was diagnosed with presumed RT-induced pericarditis. Despite anti-inflammatory therapy, he developed haemodynamic instability and clinical tamponade, with transthoracic echocardiogram showing a large circumferential pericardial effusion. He underwent emergent pericardiocentesis, and pericardial fluid cultures grew polymicrobial species. Anti-inflammatories were held, and he was started on broad spectrum intravenous antibiotics and antifungals. Due to clinical decompensation and repeat computed tomography imaging demonstrating worsening pericardial disease, he underwent pericardial irrigation and subxiphoid pericardial window. The patient died from hypoxaemic and hypercapnic respiratory failure. Autopsy revealed constrictive pericarditis and no bacterial organisms in the pericardium. DISCUSSION: Anti-inflammatories are standard treatment for viral and RT-induced pericarditis. Purulent, bacterial pericarditis is rare and an uncommon complication of RT-induced pericarditis. Polymicrobial infectious pericarditis is often refractory to intravenous antibiotics, requiring surgical intervention. This case highlights the importance of maintaining a high index of suspicion of various potential aetiologies of pericarditis in order to tailor medical and surgical therapies especially in high-risk, immunosuppressed cancer patients.

Background: the role of the R202Q (c.605G>A, p.Arg202Gln) missense variant of the MEFV gene has been debated as either a benign polymorphism or a potentially pathogenic mutation. We report and discuss here the case of a young female with corticosteroid-dependent recurrent pericarditis carrying the homozygous R202Q variant, exhibiting distinctive clinical features possibly influenced by this genetic variant. Methods: a 30-year-old woman with a previous diagnosis of cancer and recent respiratory infection presented with severe pleuritic chest pain, hypotension, tachycardia, and fever. Initial diagnostic evaluation indicated cardiac tamponade, and emergent pericardiocentesis was performed. Despite initial treatment with NSAIDs, colchicine, and corticosteroids, the patient experienced multiple recurrences. Genetic testing identified homozygous R202Q variant in the MEFV gene. Given the corticosteroid dependency and recurrent nature of her condition, IL-1 inhibitor anakinra was introduced, leading to significant improvement, although tapering below 150 mg per week failed to prevent recurrences. Results: the introduction of anakinra resulted in rapid symptom relief and resolution of pericardial effusion. However, attempts to taper or discontinue anakinra led to pericarditis recurrences. Ultimately, a maintenance dose of 50 mg every three days was established, which maintained remission for 18 months without recurrence. Despite multiple tapering attempts, further reduction in anakinra dosage was unsuccessful without triggering relapses. Conclusions: the R202Q variant, although typically considered benign, may contribute to an autoinflammatory phenotype resembling familial Mediterranean fever. This case underscores the potential pathogenicity of the homozygous R202Q variant in recurrent pericarditis and its responsiveness to IL-1 inhibition. In patients with corticosteroid-dependent recurrent pericarditis, genetic testing for the R202Q variant should be considered when anti-IL-1 drugs cannot be withdrawn. Further studies are warranted to elucidate the variant's role in pericardial inflammation and guide personalized treatment strategies. [ABSTRACT FROM AUTHOR]

Esophageal dysphagia is most commonly caused by motility disorders and intrinsic mechanical obstruction. However, extrinsic obstruction, such as pericardial effusion, is rare causes of dysphagia. We present an 89-year-old male with history of Waldenstrom macroglobulinemia, Charcot-Marie-Tooth syndrome, and basal cell carcinoma presenting with generalized weakness, productive cough, shortness of breath, and dysphagia to both solids and liquids. A chest X-ray obtained showed cardiomegaly with suggested central vascular congestion and pulmonary edema. Further imaging with computed tomography (CT) abdomen and pelvis showed a moderate-to-large pericardial effusion. Patient later developed signs and symptoms of cardiac tamponade, requiring urgent pericardiocentesis with removal of 1 L of sanguineous fluid. Up to today, only 6 cases of dysphagia due to pericardial effusion have been described. This case displays another rare case and highlights the importance of recognizing dysphagia as a critical symptom as well as non-gastrointestinal (GI) causes of dysphagia. [ABSTRACT FROM AUTHOR]

Background: Pulsed‐field ablation (PFA) has emerged as an innovative alternative to radiofrequency (RF) and cryoablation because it selectively targets myocardial tissue. Thus, we aim to estimate the efficacy and safety of PFA versus thermal ablation for atrial fibrillation (AF) ablation. Methods: A systematic review and meta‐analysis were retrieved from PubMed, WOS, SCOPUS, EMBASE, and CENTRAL through September 2023. We used RevMan V. 5.4 to pool dichotomous data using risk ratio (RR) and continuous data using mean difference (MD) with a 95% confidence interval (CI). PROSPERO ID: CRD42023480321 Results: We included 17 studies with a total of 2255 patients. PFA was significantly associated with a decreased incidence of AF recurrence (RR: 0.66 with 95% CI [0.51, 0.87], p =.003). However, there was no significant difference between PFA and thermal ablation in arrhythmia recurrence (RR: 0.92 with 95% CI [0.74, 1.46], p =.42). PFA was significantly associated with decreased total procedure time (MD: −15.15 with 95% CI [−20.23, −10.07], p <.00001), decreased heart rate change (MD: −7.39 with 95% CI [−12.16, −2.62], p =.002), decreased phrenic nerve palsy (RR: 0.38 with 95% CI [0.15, 0.98], p =.05), and reduced esophageal lesions (RR: 0.09 with 95% CI [0.01, 0.69], p =.02). On the contrary, PFA was significantly associated with increased pericardial tamponade (RR: 6.14 with 95% CI [1.43, 26.33], p =.01). Conclusion: PFA was significantly associated with decreased AF recurrence, total procedure time, heart rate change, phrenic nerve palsy, esophageal lesion, and increased incidence of pericardial tamponade compared with thermal ablation.

To introduce a novel surgical technique using the human amniotic membrane (hAM) patch technique to address refractory macular holes (MHs). After vitrectomy, the hAM patch was positioned on top of the MH with the chorion side facing downward. Viscoat (Alcon Laboratories) was applied on top of the hAM patch for better fixation. Fluid-air exchange was then performed and 20% SF6 or 10% C3F8 tamponade was administered after the surgery. Five patients with refractory MHs larger than 400 µm underwent the hAM patch technique. After a minimum 2-year follow-up, results showed 100% closure of MHs, 80% improvement in visual acuity, and a notable enhancement in best-corrected logMAR visual acuity from 0.98 to 0.72 (P = 0.039). Dislocation of hAM patch occurred among 3 out of 5 patients (60%). The hAM patch technique appears to be a promising approach for addressing refractory MHs.

The presence of pulmonary hypertension (PH) may affect whether cardiac tamponade physiology develops from a pericardial effusion. Specifically, the increased intracardiac pressure and right ventricular hypertrophy associated with PH would seemingly increase the intrapericardial pressure threshold at which the right-sided chambers collapse. In this systematic review, we examined the impact of PH on the incidence, in-hospital and long-term mortality, and echocardiographic findings of patients with cardiac tamponade. Using the PRISMA guideline, a systematic search was conducted in PubMed, Academic Search Premier, Web of Science, Google Scholar, and the Cochrane Database for studies investigating PH and cardiac tamponade. The Newcastle–Ottawa Scale was used to analyze the quality of returned studies. Primary outcomes included the incidence of cardiac tamponade, as well as in-hospital and long-term mortality rates. Secondary outcomes were the presence or absence of echocardiographic findings of cardiac tamponade in patients with PH. Forty-three studies (9 cohort studies and 34 case reports) with 1054 patients were included. The incidence of cardiac tamponade was significantly higher in patients with PH compared to those without PH, 2.0% (95% CI 1.2–3.2%) vs. 0.05% (95% CI 0.05–0.05%), p < 0.0001, OR 40.76 (95% CI 24.8–66.9). The incidence of tamponade in patients with a known pericardial effusion was similar in those with and without PH, 20.3% (95% CI 12.0–32.3%) and 20.9% (95% CI 18.0–24.1%), p = 0.9267, OR 0.97 (95% CI 0.50–1.87). In patients with tamponade, those with PH demonstrated a significantly higher in-hospital mortality than those without PH, 38.8% (95% CI 26.4–52.8%) vs. 14.4% (95% CI 14.2–14.6%), p < 0.0001, OR 3.77 (95% CI 2.12–6.70). Long-term mortality in patients with tamponade was significantly lower in those with PH than in those without PH, 45.5% (95% CI 33.0–58.5%) vs. 59.1% (95% CI 54.7–63.4%), p = 0.0258, OR 0.576 (95% CI 0.33–1.01). However, after stratifying by non-malignant etiologies, the long-term mortality benefit for those with PH disappeared. In the studies that described specific echocardiographic findings of cardiac tamponade, only 10.5% of patients with PH and tamponade showed right atrial and right ventricular collapse. When evaluating patients with pericardial effusions, physicians must recognize the effects of underlying PH on the incidence, in-hospital and long-term mortality rates, and potentially atypical echocardiographic presentation of cardiac tamponade.

Introduction Method Results Conclusion Pericardial effusion, a known complication to implantation of cardiac implantable electronic devices (CIED), may cause life‐threatening cardiac tamponade. Limited knowledge is available about risk factors for clinically relevant procedural pericardial effusion. The aim is to identify the patient‐ and procedure‐related risk factors associated with clinically relevant procedural pericardial effusion.A nationwide observational cohort study based on data on 55 121 patients from the Danish Pacemaker Register between 2000 and 2018. We defined a clinically relevant procedural pericardial effusion related to the implantation if it occurred within 90 days after the primary CIED‐procedure. Prespecified risk factors were analysed by multivariable logistic regression models to estimate the association with pericardial effusion.There were 115 (0.21%) patients diagnosed with clinically relevant procedural pericardial effusion, with a median age of 75 years and 38.3% were females. Of these, 80.9% lead to a subsequent pericardiocentesis procedure. In adjusted logistic regression analysis, an increased risk of clinically relevant pericardial effusion was associated with female sex (OR:1.49 [95%CI: 1.03–2.16]), heart failure (OR:1.54 [95%CI: 1.06–2.23]), previous cardiac surgery (OR:1.63 [95%CI: 1.05–2.55]), CRT‐device (OR:2.05 [95%CI: 1.23–3.41]), tertiary‐centres (OR:1.8 [95%CI: 1.18–2.73]), increased procedural volume per year (>1000) (OR:1.85 [95%CI: 1.03–3.30]), indication of device‐implantation (atrioventricular block) (OR:2.37 [95CI: 1.45–3.87]), and increasing number of leads implanted (two leads (OR:2.39 [95%CI: 1.43–4.00]), three leads (OR:4.77 [95%CI: 2.50–9.10])).Clinically relevant procedural pericardial effusion is a rare complication after CIED‐implantation in Denmark. This study reveals important patient‐ and procedure‐related risk factors associated with clinically relevant procedural pericardial effusion. [ABSTRACT FROM AUTHOR]

Trauma is a leading cause of death and disability worldwide across all age groups, with traumatic cardiac arrest (TCA) presenting a significant economic and societal burden due to the loss of productive life years. Despite TCA's high mortality rate, recent evidence indicates that survival with good and moderate neurological recovery is possible. Successful resuscitation in TCA depends on the immediate and simultaneous treatment of reversible causes according to pre-established algorithms. The HOTT protocol, addressing hypovolaemia, oxygenation (hypoxia), tension pneumothorax, and cardiac tamponade, forms the foundation of TCA management. Advanced interventions, such as resuscitative thoracotomy and resuscitative endovascular balloon occlusion of the aorta (REBOA), further enhance treatment. Contemporary approaches also consider metabolic factors (e.g. hyperkalaemia, calcium imbalances) and hemostatic resuscitation. This narrative review explores the advanced management of TCA and peri-arrest states, discussing the epidemiology and pathophysiology of peri-arrest and TCA. It integrates classic TCA management strategies with the latest evidence and practical applications. [ABSTRACT FROM AUTHOR]

Background: Coronary artery bypass grafting (CABG) surgery is a common procedure for managing multi-vessel coronary artery disease to revascularize the myocardium. Among the various conduits used, the left internal mammary artery (LIMA) is preferred due to its better long-term patency rate. However, CABG procedures involving LIMA may result in rare but serious complications, such as avulsion of the LIMA post-CABG, which leads to disruption of blood flow to the myocardium and the development of fatal cardiac tamponade. Case presentation: We hereby present a unique case of spontaneous avulsion of a LIMA graft to the left anterior descending artery (LAD) away from the site of anastomosis, twenty-four hours following CABG surgery in a 67-year-old male patient. Emergency re-exploration and repair of the LIMA with interposition vein graft were performed and resulted in successful stabilization of the patient's critical condition. However, this was followed by a complicated recovery period involving atrial fibrillation, acute kidney injury, and wound infection. Conclusion: Avulsion of LIMA graft following CABG is rare, yet a fatal complication that requires high clinical suspicion and prompt management. Avulsion has been reported a few times in literature following both minimal invasive and conventional CABG. Understanding the etiology, clinical presentation, and management of this complication is crucial to avoid catastrophic outcomes. [ABSTRACT FROM AUTHOR]

Background: Complications after percutaneous breast biopsy are infrequent but may include hematoma, pseudoaneurysm formation, persistent pain, infection, delayed wound healing, vasovagal reaction, hemothorax, pneumothorax, and neoplastic seeding. The risk factors include tumor factors (size, location, vascularity), procedure-related factors (needle diameter, number of biopsies), and interventionist experience. There has been no previous report of a fatal complication resulting from percutaneous breast biopsy. Case presentation: We report a 54-year-old Asian woman with a 3 cm BI-RADS® 4B left breast mass in the lower-inner quadrant who was biopsied by a 16 G needle under ultrasound guidance at a province hospital. She experienced dizziness and near-syncope afterward. The initial evaluation showed evidence of cardiac tamponade with hemodynamic instability. She underwent urgent subxiphoid pericardial window and was transferred to our facility. We brought her directly to the operating room to perform an explorative median sternotomy and found a 0.2 cm hole in the right ventricle. The injured site was successfully repaired without cardiopulmonary bypass. Postoperative echocardiography demonstrated mild right ventricular dysfunction without evidence of septal or valvular injury. She survived with no significant complications. Discussion: This case might be the first report of a life-threatening complication related to percutaneous breast core-needle biopsy. The rapid pericardial release is key to the survival of cardiac tamponade. The patient subsequently required cardiac repair and monitoring to avoid long-term complications. In this report, we suggested a safe biopsy method, complications recognition, and appropriate management of penetrating cardiac injury. Conclusion: Penetrating cardiac injury resulting from percutaneous breast biopsy is extremely rare but can occur. A biopsy must be done cautiously, and worst-case management should promptly be considered. [ABSTRACT FROM AUTHOR]

Central venous catheterization is, now, one of the most routinely used procedures in the NICUs, helping during the care of very sick infants. Pericardial effusion is a very rare but severe complication, with a high mortality. The cases described are part of an ongoing retrospective study where the use of central catheters inserted in our surgical NICU, and its complications is being analyzed. 16 cases over 13 years are presented in this article, varying in severity from mild, self-resolving cases that were discovered during routine cardiac POCUS to cases with important hemodynamic impact associated with cardiac tamponade and cardiac arrest. Due to immediate intervention, only one of the cases led to catheter-related mortality and that was under particular conditions. Our aim is to highlight the severity of this complication, the importance of early intervention, and the impact of a highly technologized unit and widely available cardiac POCUS.

Purulent pericarditis in children is a life-threatening condition causing cardiac tamponade and disrupting the hemodynamic status of the patient. It has been associated with high mortality if treatment is delayed. Furthermore, purulent pericarditis may lead to constrictive pericarditis in the long term if not fully treated. Acute purulent pericarditis should be seriously considered in every septic child presenting with signs of right heart decompensation. Echocardiography is important for diagnosis. Diagnostic pericardiocentesis should be performed. Recent experience shows that excellent results can be obtained when adequate surgical drainage and antibiotic therapy are combined. We report a case of purulent bacterial pericarditis caused by methicillin-resistant Staphylococcus aureus in an immunocompetent young child presenting with sepsis. The patient was successfully treated with a combined medical and early surgical approach. [ABSTRACT FROM AUTHOR]

Cardiac tamponade is a rare complication of hypothyroidism. In rarer cases, hypothyroidism may initially present with tamponade. Cardiac tamponade is an emergency condition that usually requires urgent intervention. However, guidelines for tamponade secondary to hypothyroidism are not optimal, and cases have been managed variably (ranging from levothyroxine alone to pericardiocentesis followed by thyroid hormone replacement) with diverse outcomes. Here, we report a case of a 42-year-old male with no medical history who presented with exertional dyspnea, lower leg swelling, facial puffiness, constipation, and weight gain. He had low blood pressure (80/60 mm Hg), normal heart rate with sinus rhythm, normal oxygen saturation, and was afebrile. Apart from a mildly raised creatinine, his test results were normal. An echocardiogram revealed features of tamponade. Further laboratory tests showed severe hypothyroidism. Following the initiation of levothyroxine, he demonstrated significant improvement. Coronary angiography revealed 95% stenosis in the mid-left anterior descending artery, treated with stenting. Serial echocardiograms showed regression of the pericardial effusion, stabilizing his condition without the need for invasive pericardiocentesis. This case highlights the importance of prompt diagnosis and management of hypothyroidism-related tamponade to prevent severe cardiac compromise. Hence, it may be necessary to consider hypothyroidism in the differential for patients with unexplained cardiac tamponade. [ABSTRACT FROM AUTHOR]

The article presents a neonatal case where cardiac tamponade developed as a complication of a peripherally inserted central catheter (PICC). Topics discussed include the potential risks associated with PICC placement, the management of pericardial effusion, and the importance of timely detection and intervention to prevent severe outcomes.

Metastasis of non–small cell lung carcinoma (NSCLC) is a rare cause of cardiac metastatic tumors (CMT). We present a case of NSCLC infiltrating the apical left ventricle mimicking cardiac aneurysm and tamponade. The patient, who had a history of NSCLC, presented with acute shortness of breath and an echocardiogram concerning for ruptured left ventricular aneurysm. A neoplastic mass found at the cardiac apex suggested CMT leading to ventricular wall rupture and cardiac tamponade. Transthoracic echocardiography is the most ubiquitous imaging modality for CMT diagnosis, with cardiac magnetic resonance imaging offering a more detailed assessment. CMT from NSCLC can cause dangerous cardiac tamponade, warranting consideration in patients with suspected metastases. KEY POINTS: Metastasis of non–small cell lung carcinoma (NSCLC) to the heart is uncommon but can lead to serious complications including life-threatening cardiac tamponade. Diagnosis of cardiac metastatic tumors from NSCLC often involves echocardiography, but cardiac magnetic resonance imaging provides additional insights in cases where echocardiography results are inconclusive.

Background Amoebiasis is a prevalent infection in the tropics and can sometimes present as liver abscess. Cardiac tamponade is an uncommon complication of ruptured amoebic liver abscess requiring urgent pericardiocentesis, which has a high success rate, but procedural complications can include injury to cardiac chambers, abdominal viscera, and even death. This case underscores the approach to diagnose and manage an unintended visceral puncture during pericardiocentesis, which is a rare but life-threatening complication. Case summary A 41-year-old male presented with intermittent fever over 2 months and chest pain for 15 days. Echocardiography revealed a significant pericardial effusion causing cardiac tamponade. In an emergency setting, percutaneous pericardiocentesis was attempted to drain the effusion. However, the pigtail inadvertently punctured a sizable liver abscess. Consequently, another pigtail was inserted into the pericardial cavity to successfully drain the effusion. Patient was discharged on Day 12 and is doing well at 6 months follow-up. Discussion A previously undiagnosed case of a ruptured amoebic liver abscess presented with the uncommon complication of cardiac tamponade, necessitating emergency pericardiocentesis, which inadvertently led to the cannulation of the liver abscess. This case underscores the significance of image-guided pericardiocentesis in minimizing procedural complications. This case also highlights the intricacies of addressing accidental visceral puncture during pericardiocentesis, specially involving the liver. It also underscores the need to consider the possibility of a ruptured amoebic liver abscess when anchovy sauce-like pus is drained from pericardial cavity, especially in high epidemiologically prevalent country like India.

Background: While most mediastinal teratomas remain asymptomatic, on rare instances it may rupture into the pericardium, leading to pericardial effusion and cardiac tamponade, which is associated with high mortality rates. Case report: A 12-year-old male presented with syncope and tachycardia, which prompted further investigation. Chest radiography revealed a lobulated and homogeneous mass in the anterior mediastinum. Subsequent thoracic computed tomography (CT) scan revealed a complex anterior mediastinal mass exhibiting cystic and solid components, with calcification, fatty elements, and a significant pericardial effusion. Pericardiocentesis, performed to alleviate the tamponade, evacuated a large volume of purulent fluid. A total resection of the mediastinal mass was performed using a transthoracic approach with a cardiac window into the pleural cavity. The resected mass was a ruptured multicystic structure filled with pus and composed of muscle and tendon tissues. Microscopic examination confirmed the diagnosis of a mature teratoma. Following the procedure, the patient experienced a complete recovery without any complications. Conclusion: The rupture of an infected mediastinal mature teratoma into the pericardium is an uncommon occurrence, yet it poses a significant threat with a heightened risk of mortality. Timely surgical intervention is imperative to minimize the complications associated with rupture.

Melioidosis, an infectious disease caused by Burkholderia pseudomallei, is prevalent in Southeast Asia and Northern Australia, presenting various clinical manifestations from asymptomatic to life-threatening infections. Although primarily affecting the lungs, intra-abdominal viscera, and musculoskeletal system, melioidosis can rarely involve the heart and mediastinum, which pose significant diagnostic and therapeutic challenges. Herein, we present the case of a 53-year-old male farmer who presented with persistent fever and chest pain, progressing to pericarditis and cardiac tamponade. Imaging revealed necrotic mediastinal lymphadenopathy and an enhancing pericardium with pericardial effusion. The patient underwent emergency surgical drainage and was treated with intravenous followed by oral antibiotics. Culture confirmed Burkholderia thailandensis, a closely related but less commonly reported species. This report highlights the complexities of diagnosing and managing B. thailandensis, which can mimic aortic disease, tuberculosis, malignancies, and other inflammatory conditions, especially in endemic areas, emphasizing the need for prompt medical and surgical treatment to improve patient outcomes.

Abstract Background Cardiac tamponade is a life-threatening condition requiring prompt diagnosis and therapeutic intervention. Diagnosis and management of cardiac tamponade in patients with human immunodeficiency virus (HIV) infection pose a major challenge for clinicians. This study aimed to investigate clinical characteristics, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade in people living with HIV. Methods Pubmed, Embase, Scopus, and Web of Science databases were systematically searched for case reports or case series reporting HIV-infected patients with cardiac tamponade up to February 29, 2024. Baseline characteristics, clinical manifestations, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade were independently extracted by two reviewers. Results A total of 37 articles reporting 40 HIV-positive patients with cardiac tamponade were included. These patients mainly experienced dyspnea, fever, chest pain, and cough. They were mostly presented with abnormal vital signs, such as tachypnea, tachycardia, fever, and hypotension. Physical examination predominantly revealed elevated Jugular venous pressure (JVP), muffled heart sounds, and palsus paradoxus. Echocardiography mostly indicated pericardial effusion, right ventricular collapse, and right atrial collapse. Most patients underwent pericardiocentesis, while others underwent thoracotomy, pericardiotomy, and pericardiostomy. Furthermore, infections and malignancies were the most common etiologies of cardiac tamponade in HIV-positive patients, respectively. Eventually, 80.55% of the patients survived, while the rest expired. Conclusion Infections and malignancies are the most common causes of cardiac tamponade in HIV-positive patients. If these patients demonstrate clinical manifestations of cardiac tamponade, clinicians should conduct echocardiography to diagnose it promptly. They should also undergo pericardial fluid drainage and receive additional therapy, depending on the etiology, to reduce the mortality rate.

Abstract Background Pericardiocentesis offers a definitive diagnostic and a life-saving therapeutic modality through removal of pericardial fluid and relief of high intrapericardial pressure. Percutaneous pericardiocentesis has been performed via different approaches depending on different institutional experiences. In this paper, we present our institutional experience and review the current literature of the different approaches for performing percutaneous pericardiocentesis. Materials and methods We evaluated consecutive patients who underwent echocardiographic-guided pericardiocentesis via the apical approach for pericardial effusion between the period of April 1st, 2022, and April 1st, 2023, at University of Arkansas for Medical Sciences (UAMS). Health records were reviewed for clinical presentations, available imaging findings, procedural outcomes, and short-term follow up. Results A total of eight consecutive cases of pericardiocentesis via the apical approach were found. Seven were successful. No complications were reported. Six patients had evidence of tamponade physiology on echocardiogram. Conclusion Historically, pericardiocentesis has been most performed via the subxiphoid approach. However, an ultrasound-guided apical approach offers a safe and effective alternative and may be preferable in patients with challenging anatomies.

Hypothyroidism is an endocrine disorder with a high worldwide prevalence and diverse clinical presentation and can affect multiple organ systems. It can be asymptomatic and subclinical or overtly symptomatic and can prove to be fatal if left untreated. It is an established cause of pericardial effusion, which can rarely lead to cardiac tamponade and severe haemodynamic instability. Herein, we present a few unusual case reports of patients presenting with hypothyroidism with varied causes who presented with tamponade.

Abstract Background Thymic mucosa-associated lymphoid tissue (MALT) lymphoma is rare and is known to be associated with Sjögren’s syndrome (SjS). SjS is rarely accompanied by serositis. Here, we describe the first case of postoperative cardiac tamponade and acute pleuritis in a patient with thymic MALT lymphoma associated with SjS. Case presentation A 33-year-old woman with SjS presented with an anterior mediastinal mass on chest computed tomography, which was performed for further examination of the condition. Suspecting a thymic MALT lymphoma or thymic epithelial tumor, total thymectomy was performed. The mediastinal mass was histopathologically diagnosed as a thymic MALT lymphoma. The patient was discharged with a good postoperative course but visited the hospital 30 days after surgery for dyspnea. Cardiac tamponade was observed and drainage was performed. Four days after pericardial drainage, chest radiography revealed massive left pleural effusion, and thoracic drainage was performed. The patient was diagnosed with serositis associated with SjS and treated with methylprednisolone, which relieved cardiac tamponade and pleuritis. Conclusions Surgical invasion of thymic MALT lymphomas associated with SjS may cause serositis. Postoperative follow-up should be conducted, considering the possibility of cardiac tamponade or acute pleuritis due to serositis as postoperative complications.

Abstract The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64–14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826–0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma.

Systemic lupus erythematosus (SLE) is an autoimmune disorder with protean manifestations. most commonly affecting women Cardiovascular manifestations are common but rare at initial presentation. Our patient presented with impending cardiac tamponade and was subsequently diagnosed with SLE. A 31-year-old female presented with fever, rash, and progressive exertional dyspnea. On examination, she had an elevated JVP and muffled heart sounds and features of pulmonary hypertension her baseline blood investigations showed acute kidney injury, albuminuria, and grossly elevated BNP. Chest radiography showed an enlarged cardiac silhouette and echocardiography showed large pericardial effusion with impending cardiac tamponade for which the patient underwent emergency pericardiocentesis. ANA profile confirmed our diagnosis of SLE with positive anti-dsDNA, anti-nucleosomes, anti-histones, anti-SSA, and anti-Jo 1. Being positive she was treated with pulse steroids and hydroxychloroquine. Renal biopsy was also done which showed class IV lupus nephritis. She improved clinically and was discharged with oral steroids, mycophenolate mofetil, and hydroxychloroquine. Cardiac tamponade is a life-threatening condition and SLE is an important differential to be considered during evaluation.

Background: Percutaneous coronary intervention (PCI), also known as coronary angioplasty, is the preferred strategy for treating obstructive coronary artery disease. Existing literature suggests the worsening of clinical outcomes in patients with previous coronary artery bypass grafting (CABG) history. In light of this, a comprehensive systematic review and meta-analysis was performed. Methods: Databases including PubMed, Cochrane Library, and ScienceDirect were utilized for the inclusive systematic search dating from inception to September 01, 2023. The risk of bias assessment was performed using the Newcastle-Ottawa scale for cohort studies, and the Cochrane Risk of Bias Tool for randomized controlled trials. Results: Ultimately, there were 16 eligible studies pooled together, involving a total of 250 684 patients, including 231 552 CABG-naïve patients, and 19 132 patients with a prior history of CABG. Overall, patients with CABG history were associated with significantly greater short-term mortality (P =.004), long-term mortality (P =.005), myocardial infarction (P <.00001), major adverse cardiovascular events (P =.0001), and procedural perforation (P <.00001). Contrastingly, CABG-naïve patients were associated with significantly greater risk of cardiac tamponade (P =.02) and repeat CABG (P =.03). No significant differences in stroke, bleeding, revascularization, or repeat PCI were observed. Conclusion: Comparatively worsened clinical outcomes were observed, as patients with prior CABG history typically exhibit complex coronary anatomy, and have higher rates of comorbidities in comparison to their CABG-naïve counterparts. The refinement of current procedural and surgical techniques, in conjunction with continued research endeavors, are needed in order to effectively address this trend. [ABSTRACT FROM AUTHOR]

Background: Cardiac tamponade is a life-threatening condition requiring prompt diagnosis and therapeutic intervention. Diagnosis and management of cardiac tamponade in patients with human immunodeficiency virus (HIV) infection pose a major challenge for clinicians. This study aimed to investigate clinical characteristics, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade in people living with HIV. Methods: Pubmed, Embase, Scopus, and Web of Science databases were systematically searched for case reports or case series reporting HIV-infected patients with cardiac tamponade up to February 29, 2024. Baseline characteristics, clinical manifestations, paraclinical findings, therapeutic options, patient outcomes, and etiologies of cardiac tamponade were independently extracted by two reviewers. Results: A total of 37 articles reporting 40 HIV-positive patients with cardiac tamponade were included. These patients mainly experienced dyspnea, fever, chest pain, and cough. They were mostly presented with abnormal vital signs, such as tachypnea, tachycardia, fever, and hypotension. Physical examination predominantly revealed elevated Jugular venous pressure (JVP), muffled heart sounds, and palsus paradoxus. Echocardiography mostly indicated pericardial effusion, right ventricular collapse, and right atrial collapse. Most patients underwent pericardiocentesis, while others underwent thoracotomy, pericardiotomy, and pericardiostomy. Furthermore, infections and malignancies were the most common etiologies of cardiac tamponade in HIV-positive patients, respectively. Eventually, 80.55% of the patients survived, while the rest expired. Conclusion: Infections and malignancies are the most common causes of cardiac tamponade in HIV-positive patients. If these patients demonstrate clinical manifestations of cardiac tamponade, clinicians should conduct echocardiography to diagnose it promptly. They should also undergo pericardial fluid drainage and receive additional therapy, depending on the etiology, to reduce the mortality rate. [ABSTRACT FROM AUTHOR]

Background Objectives Methods Results Conclusions Safety data of the latest radiofrequency (RF) technologies during atrial fibrillation (AF) ablation in real‐world clinical practice are limited.We sought to evaluate the acute procedural safety of the four latest ablation catheters commonly used for AF ablation.A total of 3957 AF ablation procedures performed between January 2022 and December 2023 at 20 centers with either the THERMOCOOL SMARTTOUCH SF (STSF), TactiCath (TC), QDOT Micro (QDM), or TactiFlex (TF) were retrospectively analyzed.In total, QDM, STSF, TF, and TC were used in 343 (8.7%), 1793 (45.3%), 1121 (28.4%), and 700(17.7%) procedures. Among 2406 index procedures, electrical pulmonary vein isolations were successfully achieved in 99.5%. Despite similar total procedure times in the four groups, the total fluoroscopic time was significantly shorter for QDM/STSF with CARTO than TF/TC with EnSite (18.7 ± 14 vs. 27.6 ± 20.6 min, p < .001) and longest in the TF group. The incidence of cardiac tamponade was 0.7% (0.5% and 0.9% during index and redo procedures, 0.8% and 0.3% for paroxysmal and non‐paroxysmal AF) and was significantly lower for QDM/STSF than TF/TC (0.2% vs. 1.1%, p = .008) and highest in the TF group. The incidence of cardiac tamponade was higher for TF than TC and STSF than QDM. In the multivariate analysis, TF/TC with EnSite was a significant independent predictor of cardiac tamponade during both the index (odds ratio [OR] = 4.8, 95% confidence interval [CI] = 1.3–17.5, p = .02) and all procedures (OR = 3.0, 95% CI = 1.3–7.2, p = .01).The incidence of cardiac tamponade and the fluoroscopic time during AF ablation significantly differed among the latest RF catheters and mapping systems in real‐world clinical practice.

Introduction: Cardiac arrests are traditionally classified according to the setting in which they occur, including out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA). However, cardiac arrests that occur in the emergency department (EDCA) could constitute a third category, due to the peculiar characteristics of the emergency department (ED). In recent years, the need to study EDCAs separately from other intra-hospital events has emerged. The aim of this study was to describe the characteristics and outcomes of a cohort of patients experiencing EDCA in an Italian hospital over a 14-year period. Methods: This was a single-centre retrospective observational study conducted in the ED of the Santa Croce e Carle Hospital in Cuneo, Italy. All adult patients who experienced EDCA between 1 January 2010 and 30 June 2023 were included. OHCA patients, those arriving in the ED with on-going resuscitation measures, patients with EDCA not undergoing resuscitation, and patients with post-traumatic cardiac arrest were excluded from the study. The main outcome of the study was survival at hospital discharge with a favourable neurological outcome. Results: 350 cases of EDCA were included. The median age was 78 (63–85) years, and the median Charlson Comorbidity Index score was 5 (3–6). A total of 35 patients (10%) survived to hospital discharge with a cerebral performance category (CPC) Score of 1–2; survival in the ED was 28.3%. The causes of cardiac arrests were identified in 212 cases (60.6%) and included coronary thrombosis (35%), hypoxia (22%), hypovolemia (17%), pulmonary embolism (11%), metabolic (8%), cardiac tamponade (4%), toxins (2%) and hypothermia (1%). Variables associated with survival with a favourable neurological outcome were young age, a lower Charlson Comorbidity Index, coronary thrombosis as the primary EDCA cause, and shockable presenting rhythm; however, only the latter was associated with the outcome in a multivariate age-weighted model. Conclusions: In a cohort of patients with EDCA over a period of more than a decade, the most frequent cause identified was coronary thrombosis; 10% of patients survived with a good neurological status, and the only factor associated with the best prognosis was presenting a shockable rhythm. EDCA should be considered an independent category in order to fully understand its characteristics and outcomes. [ABSTRACT FROM AUTHOR]

Background: Pericardiocentesis offers a definitive diagnostic and a life-saving therapeutic modality through removal of pericardial fluid and relief of high intrapericardial pressure. Percutaneous pericardiocentesis has been performed via different approaches depending on different institutional experiences. In this paper, we present our institutional experience and review the current literature of the different approaches for performing percutaneous pericardiocentesis. Materials and methods: We evaluated consecutive patients who underwent echocardiographic-guided pericardiocentesis via the apical approach for pericardial effusion between the period of April 1st, 2022, and April 1st, 2023, at University of Arkansas for Medical Sciences (UAMS). Health records were reviewed for clinical presentations, available imaging findings, procedural outcomes, and short-term follow up. Results: A total of eight consecutive cases of pericardiocentesis via the apical approach were found. Seven were successful. No complications were reported. Six patients had evidence of tamponade physiology on echocardiogram. Conclusion: Historically, pericardiocentesis has been most performed via the subxiphoid approach. However, an ultrasound-guided apical approach offers a safe and effective alternative and may be preferable in patients with challenging anatomies. [ABSTRACT FROM AUTHOR]

The occurrence of sporadic rickettsial infections has been consistently undervalued and overlooked, primarily owing to a limited emphasis on routine examinations for rickettsioses in clinical practice. At present, the immunofluorescence assay is the prevailing diagnostic method for suspected rickettsioses that enables the detection of specific antibodies against rickettsia in human serum. Herein, we present an exceptional instance of rickettsial infection that was characterized by a rare manifestation of extensive pericardial effusion leading to dyspnea and cardiac tamponade. A diagnosis of chronic fibrosing pericarditis was established based on pericardium tissue obtained through pericardiotomy, and a conclusive metagenomic next‐generation sequencing test confirmed the presence of Rickettsia felis infection. The cat flea, scientifically known as Ctenocephalides felis, is the predominant carrier of R. felis. An escalating incidence of human R. felis infections has raised concerns, particularly in light of the burgeoning population of domesticated animals in many contemporary societies.

Introduction. The introduction of Bruton's tyrosine kinase (BTK) inhibitors significantly improved the management of chronic lymphocytic leukemia (CLL). However, BTK carry the risk of cardiotoxicity, which is not only limited to atrial fibrillation. Case Reports. We report three cases of patients on BTK inhibitors who developed acute pericarditis and cardiac tamponade. We report the first patient who developed this complication on treatment with zanubrutinib. This patient's treatment was changed to zanubrutinib due to atrial fibrillation. Shortly after cardioversion, he developed cardiac tamponade and shock. He underwent pericardiocentesis, received treatment for acute pericarditis with steroids and colchicine, and made a full recovery. We also report two further cases, both involving patients treated with ibrutinib. These patients also developed acute pericarditis and cardiac tamponade and required pericardiocentesis. All three patients discontinued BTK therapy following the events. Conclusions. These three cases highlight the rare but potentially life‐threatening risk of cardiac tamponade which can occur even with newer generations of BTK inhibitors. Haemato‐oncologists should remain vigilant in patients who report dyspnea or who show sinus tachycardia on routine electrocardiography. Even in the absence of classical clinical signs of tamponade, patients require urgent evaluation with echocardiography and potentially emergency pericardiocentesis. [ABSTRACT FROM AUTHOR]

Hodgkin lymphoma (HL) is an uncommon malignancy that is characterized by Hodgkin or Reed–Sternberg cells. Cardiac implications of HL remain one of the least investigated subjects. There are few case reports in the literature of cardiac tamponade in HL patients. We describe a case of a 21‐year‐old female patient who presented with cardiac tamponade as an initial presentation of HL. Any pericardial effusion significant for tamponade requires immediate drainage and fluid analysis for thorough investigation. Prompt identification and timely intervention are crucial in effectively addressing these complex situations. Therefore, clinicians should maintain heightened awareness in such cases.

Introduction Methods Results Conclusion The QDOT MICROTM Ablation Catheter is a next‐generation ablation catheter that allows for high‐power ablation up to 90 watts.We aimed to assess AE associated with the QDOT MICROTM catheter using the MAUDE database. A MAUDE database search was conducted on May 25, 2024, to capture all AEs (since FDA approval) associated with this ablation catheter.A total of 302 AEs from November 23, 2022, to April 30, 2024, were reported including 148 (49%) catheter‐related issues and 154 (51%) clinical complications. Among the catheter‐related issues, physical catheter damage (74.3%, n = 110) was most common, followed by communication or display issue (10.8%, n = 16), irrigation issue (9.5%, n = 14), signal issue or artifact (3.4%, n = 5), and inaccurate temperature measurement (2.0%, n = 3). Regarding clinical complications, the most common AE was pericardial effusion (43.5%, n = 67), followed by char formation (11.7%, n = 18), catheter thrombosis (7.1%, n = 11), stroke (7.1%, n = 11), pericarditis (7.1%, n = 11), esophageal complications (6.5%, n = 10), phrenic nerve palsy (3.9%, n = 6), cardiac arrest (3.9%, n = 6), significant AV block (3.9%, n = 6), pulmonary vein stenosis (3.2%, n = 5), coronary artery spasm (1.3%, n = 2), and pulmonary embolism (0.6%, n = 1). There were 11 deaths (five related to esophageal complications, five related to cardiac arrest, and one related to pericardial effusion with cardiac tamponade).As high‐power ablation strategy with novel ablation catheters is becoming more widely utilized, operators must be aware of potential catheter‐related issues and clinical complications that may arise. More data are needed to further evaluate risks of these complications to improve the catheter's safety and efficacy. [ABSTRACT FROM AUTHOR]

Systemic lupus erythematosus (SLE) is an autoimmune disease with various clinical manifestations that can affect multiple organs and systems. One of the severe complications associated with SLE is cardiac tamponade, a rare and life-threatening complication. In this paper, we present the case of a 36-year-old woman who was diagnosed with SLE after an episode of cardiac tamponade. Large pericardial effusions with cardiac tamponade are rarely encountered in SLE, particularly as the onset of the disease. This case highlights the importance of early recognition of cardiac tamponade and raises awareness of the fact that SLE can present with cardiac involvement, such as cardiac tamponade, at the onset of the disease. Multidisciplinary care involving rheumatologists, cardiologists, and other specialists is essential in the management of SLE with cardiac complications. [ABSTRACT FROM AUTHOR]

An 11‐year‐old female spayed German Wirehaired Pointer with a 1‐week history of lethargy, hyporexia, diarrhea, and coughing presented with pericardial effusion causing cardiac tamponade. An echocardiogram revealed no structural cause for pericardial effusion. The pericardial effusion was an exudate with mixed macrophagic and neutrophilic inflammation. Morulae occasionally were found within neutrophils. The pericardial fluid and blood were qPCR and cPCR positive for Anaplasma phagocytophilum (NC State University, Vector‐borne Disease Diagnostic Laboratory, Raleigh, NC). The dog's blood was negative by ELISA (Vetscan Flex4 Rapid Test, Zoetis, Parsippany, NJ) for A. phagocytophilum antibodies at initial presentation and subsequently positive (SNAP4DxPlus, IDEXX, Westbrook, ME) 7 days later. After pericardiocentesis and administration of doxycycline (5 mg/kg PO q12h for 14 days), a repeat echocardiogram performed 1 month later showed no recurrence of pericardial effusion.

Hypothyroidism is an endocrine disorder with a high worldwide prevalence and diverse clinical presentation and can affect multiple organ systems. It can be asymptomatic and subclinical or overtly symptomatic and can prove to be fatal if left untreated. It is an established cause of pericardial effusion, which can rarely lead to cardiac tamponade and severe haemodynamic instability. Herein, we present a few unusual case reports of patients presenting with hypothyroidism with varied causes who presented with tamponade. [ABSTRACT FROM AUTHOR]

Introduction. One of the most common pathologies of the pericardium is pericarditis, which can present as acute, subacute or chronic pericarditis, pericardial effusion, cardiac tamponade or constrictive pericarditis. However, it is a rare condition in the pediatric population. Methods. A series of cases of patients with pericarditis who were taken to pericardiotomy, pericardial drainage and anterior partial pericardiectomy, between July 2014 and June 2023 is presented. Demographic and clinical variables were collected, microbiological isolates and the management received were evaluated. Results. A total of 12 patients underwent minimally invasive surgical management; of these, 58% belonged to indigenous communities and lived in rural areas. Half had associated pneumonia. In most cases, no microbiological isolation was obtained. Conclusion. The need for surgical management is determined by the impact on the hemodynamic variables related to the effusion and pericardial compromise. Partial pericardiectomy by thoracoscopy is an alternative in these cases. [ABSTRACT FROM AUTHOR]

We present the case of a 55-year-old male patient with subacute myocardial infarction and hemorrhagic pericardial effusion that led to cardiac tamponade. The patient presented with the clinical picture of shock and a medical history of a three-day fever, as well as repeated syncope the night before admission. Coronarography established subacute occlusion of the first marginal branch of the left coronary artery, and percutaneous coronary intervention was performed on the first marginal branch, and pericardiocentesis was performed as well, which resulted in the evacuation of 450 mL of hemorrhagic pericardial effusion. Extensive imaging eliminated rupture of the left ventricular free wall. Laboratory testing did not demonstrate the presence of comorbid immunological or malignant diseases. The patient’s status subsequently remained stable during hospitalization and in the six-month follow-up, and the pericardial effusion is in regression. [ABSTRACT FROM AUTHOR]

Traumatic cardiac arrest is a rare and generally fatal complication of major trauma. The majority of cases result from potentially salvageable pathology such as exsanguinating haemorrhage or cardiac tamponade. Resuscitative thoracotomy is a rapid, straightforward, non-specialist procedure which can be lifesaving in appropriately selected trauma patients. This article provides a detailed review of the relevant pathophysiology, indications and contraindications, necessary equipment and techniques, and factors influencing patient outcomes.

Background: Cardiac tamponade (CT) is a rare but life-threatening complication of cardiac interventions, requiring immediate pericardial cavity pressure relief. While pericardiocentesis often suffices, and some cases necessitate open-chest surgery. This decision is frequently based on individual physician’s experience. This study aims to identify high-risk CT patients following cardiac intervention, advocating for early, decisive surgical intervention. Methods: A retrospective analysis was conducted on 51 patients who developed iatrogenic CT at our center between October 2013 and October 2023. Patients were classified based on the necessity for open-chest surgery. The study evaluated a variety of factors, including baseline characteristics, therapeutic approaches, and outcomes. Results: Of the 51 patients with iatrogenic CT, 49 patients were successfully treated without open-chest surgery, with an average immediate drainage volume of 208.2 ± 173.8 mL. In contrast, the two patients requiring open-chest surgery had significantly higher drainage volumes, exceeding 500 mL, with over 300 mL drained in the first hour, indicating laceration injuries. Patients not requiring open-chest surgery demonstrated favorable outcomes. Conclusions: The majority of patients with iatrogenic CT and non-lacerated injuries experienced a favorable prognosis following pericardiocentesis. However, in cases of lacerated injuries with drainage volume was above 300 mL per hour, pericardiocentesis alone could not stabilize the hemodynamics due to persistent bleeding. Immediate surgery may be needed in these cases. [ABSTRACT FROM AUTHOR]

Background Cardiac tamponade due to perforation of a cardiac chamber is a rare complication occurring in only 0.3% of patients undergoing permanent pacemaker (PM) implantation. Notably, perforation of the right coronary artery (RCA) following permanent PM implantation has only been reported twice in the literature. We report a rare case of RCA perforation leading to life-threatening cardiac tamponade with symptom onset 4 days after PM implantation Case summary A 75-year-old woman underwent permanent PM implantation without any difficulties in placing pacemaker leads and with good thresholds. Four days later, the patient was readmitted in a state of shock due to cardiac tamponade. A blood gas analysis on the bloody pericardial effusion raised suspicion of ongoing arterial bleeding. A CT scan ruled out aortic dissection; instead, the source of bleeding was identified as a perforation in the RCA, which was managed surgically. Discussion This case highlights the necessity of coronary artery perforation being among the differential diagnoses of cardiac tamponade after PM implantation, and it stresses the usefulness of performing a blood gas analysis on the bloody pericardial effusion.

Background Cardiac tamponade is a life-threatening compression of the heart caused by the accumulation of fluid in the pericardial sac. Although central venous catheters (CVCs) are essential in modern medicine, they carry a certain risk of complications including cardiac tamponade. Case summary A 12-year-old female was involved in a road accident reporting multiple severe traumatic injuries, including a left humerus fracture and subdural haemorrhage. After 2 days in the intensive care unit, she suddenly developed hypotension and cardiac tamponade was diagnosed. Analysis of the pericardial fluid showed high glucose levels comparable to the parenteral nutrition that she was receiving. Retraction of the CVC allowed resolution of the effusion. Discussion Cardiac tamponade is a rare but serious adverse event after CVC insertion, mostly among younger patients. Awareness of this risk allows physicians to promptly recognize and treat this dangerous complication. [ABSTRACT FROM AUTHOR]

Background Primary cardiac diffuse large B-cell lymphoma (CDLBCL) is an exceptionally rare entity, estimated to represent less than 1% of all primary cardiac tumours. In this case report, we emphasize the diagnostic importance of multimodality imaging and the need for additional procedures, such as tissue biopsy, in a case with a primary cardiac lymphoma presenting with cardiac tamponade. Case summary An 80-year-old male was admitted to the emergency department with a life-threatening tamponade demanding immediate sternotomy. Pre-operative echocardiography unveiled pericardial effusion and a thickened apex. While computed tomography ruled out an aortic dissection, surgery revealed an unexpected vascular-rich mass at the right ventricle and apex, too perilous for biopsy. Post-operative imaging misinterpreted this mass as a benign haematoma. Subsequently, the patient was admitted to the intensive care unit, but after a conservative treatment strategy, the patient died. An autopsy revealed a primary CDLBCL. Discussion This case demonstrates the deceptive nature of primary CDLBCL, often complicated by cardiac tamponade. It underscores the pivotal role of pathologic assessment, even amidst the perils of sternotomy, to determine the origin of abnormal cardiac masses. A heightened awareness among physicians is imperative, for such elusive diagnoses may slip by, with potentially fatal outcomes. [ABSTRACT FROM AUTHOR]

Introduction Methods Results Conclusion While right ventricular pacing (RVP) is the conventional temporary pacing modality used for transcatheter aortic valve replacement (TAVR), this approach possesses inherent risks and procedural challenges. We aim to assess and compare the safety and efficacy of left ventricular pacing (LVP) and RVP during TAVR and balloon aortic valvuloplasty (BAV).Following PRISMA guidelines, a comprehensive literature search was conducted in four databases from inception to December 15th, 2023. We included observational studies and clinical trials comparing LVP with RVP during TAVR and BAV procedures. Primary outcomes included short‐term mortality, mortality due to cardiac tamponade, and procedural complications including bleeding, vascular complications, and cardiac tamponade. Secondary outcomes comprised procedure duration and length of hospital stay.Five studies involving 830 patients with RVP and 1577 with LVP were included. Short‐term mortality was significantly higher in the RVP group (RR 2.32, 95% CI: [1.37–3.93], P = .002), as was the incidence of cardiac tamponade (RR 2.19, 95% CI: [1.11–4.32], P = .02). LVP demonstrated shorter hospital stays (MD = 1.34 d, 95% CI: [0.90, 1.78], P < .001) and reduced procedure duration (MD = 7.75 min, 95% CI: [5.08, 10.41], P < .00001) compared to RVP. New pacemaker implantation was higher in the RVP group (RR 2.23, 95% CI: [1.14, 4.39], P = .02).LVP during TAVR and BAV emerges a safer alternative to RVP, offering reduced mortality, hospital stays, and procedure durations.

Objective: This study aims to elucidate the clinical features observed in cases of pediatric acute myeloid leukemia (AML) initially presenting with cardiac tamponade and to share treatment experiences. Materials and methods: Five pediatric patients were initially diagnosed with AML accompanied by cardiac myeloid sarcoma (MS). The diagnosis was established by examining our hospital records and reviewing pertinent literature from 1990 to July 2023, accessible through MEDLINE/PubMed. We comprehensively assessed the clinical characteristics and treatment modalities employed for these patients. Result: Five pediatric patients presented with acute symptoms, including shortness of breath, malaise, cough, and fever, leading to their hospitalization. Physical examination revealed irritability, hypoxia, tachypnea, tachycardia, and hypotension. Initial detection utilized chest X-ray or echocardiogram, leading to subsequent diagnoses based on pericardial effusion and/or bone marrow examination. Two patients received chemotherapy at the time of initial diagnosis, one with cytarabine and etoposide, and the other with cytarabine and cladribine. Post-treatment, their bone marrow achieved remission, and over a 2.5-year follow-up, their cardiac function remained favorable. Unfortunately, the remaining three patients succumbed within two weeks after diagnosis, either due to receiving alternative drugs or without undergoing chemotherapy. Conclusion: This is the first and largest case series of pediatric AML patients with cardiac MS, manifesting initially with cardiac tamponade. It highlights the rarity and high mortality associated with this condition. The critical factors for reducing mortality include identifying clinical manifestations, conducting thorough physical examinations, performing echocardiography promptly, initiating early and timely pericardial drainage, and avoiding cardiotoxic chemotherapy medications.
