ABSTRACT
BACKGROUND: Higher rates of CIED implantations have been associated with an increased rate of lead failures and complications resulting in higher rates of transvenous lead extractions (TLE). OBJECTIVE: To assess the trends TLE admissions and evaluate the patient related predictors of safety outcomes. METHODS: National Readmission Database was queried to identify patients who underwent TLE from January 2016 to December 2019. We conducted a multivariate regression analysis to identify variables associated with in-hospital mortality in patients undergoing TLE. Additionally, we compared trends and outcomes of TLE among patients with prior sternotomy versus those without prior sternotomy and analyzed sex-based differences among patients undergoing TLE. RESULTS: We identified 30,128 hospitalizations for TLE. The index admission in-hospital mortality rate was 3.21% with cardiac tamponade happening in 1.46% of the admissions. Age, infective endocarditis, CKD, congestive heart failure and anemia were associated with higher in-hospital mortality rates. There was a lower rate of in-hospital mortality in patients with history of prior sternotomy versus patients without (OR 0.72, CI: 0.59-0.87, p-value < 0.001). There was no difference in in-hospital mortality rate between males and females. Females had a shorter length and a higher cost of stay when compared to male gender. CONCLUSION: TLE admissions continue to increase. Overall rates of mortality and complications are relatively low. Patients with prior sternotomy had better outcomes and less complications when compared to those without prior sternotomy. Female gender is associated with higher rates of cardiac tamponade, yet shorter length of stay with lower cost.
ABSTRACT
Cardiac angiosarcomas are rare and generally followed by a high level of metastasis with poor median survival outcomes. Echocardiograms, CT scans, and MRIs are the standard methods for finding sites of cardiac tumors; however, immunohistochemical confirmation is necessary for a definitive diagnosis of angiosarcoma. A 58-year-old male presented to the emergency room with one week of dyspnea on moderate exertion accompanied by chest pain and alleviated with rest. A workup done to evaluate mass found a single 5 x 3.5 x 4.8 cm mass heavily vascularized by the right coronary artery and left circumflex involving the free wall of the right atrium with no extension to the tricuspid valve. Surgical resection was performed, and immunohistochemistry was consistent with a primary cardiac angiosarcoma. An exudative fluid analysis on pericardial and pleural fluid analysis may warrant screening for malignancy more frequently in concurrence with a patient's history and presentation. Although the time from onset of symptoms to diagnosis of cardiac angiosarcoma is not well established, further investigation of such correlation may offer insight into survival post-treatment.
ABSTRACT
Pericardial decompression syndrome is an ambiguous clinical entity which has generated controversy regarding its existence. Following pericardial decompression, patients experienced clinical deterioration ranging in complications from pulmonary edema to death that could not be attributed to any other distinct clinical pathology. Multiple theories have suggested the pathophysiology behind pericardial decompression syndrome is related to preload-afterload mismatch following pericardial decompression, coronary microvascular ischemia, and stress from high adrenergic state. Our review aims to describe this syndrome by analyzing demographics, etiology of pericardial effusion, method of drainage, volume of pericardial fluid removed, time to decompensation, and clinical outcomes. A systematic review of MEDLINE/PubMed and Google Scholar literature databases were queried for case reports, case series, review articles, and abstracts published in English journals between 1983 and December 2022. Each author's interpretation of echocardiographic and/or pulmonary arterial catheterization data provided in the case reports was used to characterize ventricular dysfunction. Based on our inclusion criteria, 72 cases of pericardial decompression syndrome were included in our review. Our results showed that phenotypic heterogeneity was present based on echocardiographic findings of right/left or biventricular failure with similar proportions in each type of ventricular dysfunction. Time to decompensation was similar between immediate, subacute, and acute cases with presentation varying between hypoxic respiratory failure and shock. This review article highlights theories behind the pathophysiology, clinical outcomes, and therapeutic options in this high mortality condition.
ABSTRACT
PURPOSE: Emergency resuscitative thoracotomy (ERT) is a final salvage procedure for critically injured trauma patients. Given its low success rate and ambiguous indications, its use in blunt trauma scenarios remains highly debated. Consequently, our study seeks to ascertain the overall survival rate of ERT in blunt trauma patients and determine which patients would benefit most from this procedure. METHODS: A retrospective case-control study was conducted for this research. Blunt trauma patients who underwent ERT between January 2020 and December 2023 in our trauma center were selected for analysis, with the endpoint outcome being in-hospital survival, divided into survival and non-survival groups. Inter-group comparisons were conducted using Chi-square and Fisher's exact tests, the Kruskal-Wallis test, Student's t-test, or the Mann-Whitney U test. Univariate and multivariate logistic regression analyses were conducted to assess potential predictors of survival. Then, the efficacy of the predictors was assessed through sensitivity and specificity analysis. RESULTS: A total of 33 patients were included in the study, with 4 survivors (12.12%). Multivariate logistic regression analysis indicated a significant association between cardiac tamponade and survival, with an adjusted odds ratio of 33.4 (95% CI: 1.31 - 850, p = 0.034). Additionally, an analysis of sensitivity and specificity, targeting cardiac tamponade as an indicator for survivor identification, showed a sensitivity rate of 75.0% and a specificity rate of 96.6%. CONCLUSION: The survival rate among blunt trauma patients undergoing ERT exceeds traditional expectations, suggesting that select individuals with blunt trauma can significantly benefit from the procedure. Notably, those presenting with cardiac tamponade are identified as the subgroup most likely to derive substantial benefits from ERT.
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.
ABSTRACT
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
Superior vena cava (SVC) syndrome, once a rarity, has seen an uptick in cases with diverse origins. While this disease process is clinically diagnosable, imaging modalities and tissue biopsies further refine interventions. The clinical presentation includes but is not limited to edema of the arms, neck, and head, facial plethora, cyanosis, and or distention of subcutaneous vessels. SVC syndrome can be attributed to extrinsic compression or thrombosis in many cases. If symptoms are not life-threatening, the overall morbidity is based on the underlying root cause. Few cases have been reported with associated death due to epistaxis. However, the obstruction itself can be initially asymptomatic and then slowly progress over months to years. This case report highlights a distinct instance of SVC syndrome with notable risk factors: implantable cardioverter defibrillator placement and prior cardiac trauma status post-intervention.
ABSTRACT
Influenza B infection, although primarily recognized for respiratory symptoms, can lead to rare but severe cardiac complications such as pericardial effusion and cardiac tamponade. We present a case of a 33-year-old female with morbid obesity who initially exhibited flu-like symptoms, was subsequently diagnosed with influenza B infection, and was discharged with symptomatic treatment. Despite initial discharge, she returned with worsening weakness, gastrointestinal symptoms, and shortness of breath. Imaging studies confirmed pericardial effusion with early signs of tamponade, necessitating an emergent intervention. The patient underwent subxiphoid pericardial window and fluid removal, followed by colchicine treatment to prevent recurrence. Our case highlights the importance of recognizing and promptly managing rare influenza-related complications, particularly in patients without significant comorbidities. It underscores the value of a proactive approach, utilizing point-of-care ultrasound and echocardiography for early diagnosis and intervention to mitigate mortality and morbidity risks associated with pericarditis and cardiac tamponade secondary to influenza B.
ABSTRACT
Systemic Lupus erythematosus (SLE) is an autoimmune disorder characterized by the proliferation of autoantibodies and immune dysregulation resulting in damage to many body organs. Pediatric SLE usually presents with fever, joint pain, rashes, and lupus nephritis. It is uncommon to have large pericardial effusions in children with SLE and cardiac tamponade as the initial presentation of SLE is even rarer. An 11-year-old female presented to our Children Emergency Unit with fever and fast breathing for two weeks, bilateral leg swelling of four days, and cough of two days duration. She was acutely ill, tachypneic, and dyspneic with marked orthopnea, bilateral leg edema, and raised JVP. She was tachycardic with a diffuse apex beat. Chest X-ray showed a large globular heart. 2D-Echocardiography showed a large circumferential pericardial effusion with a dilated non-collapsing IVC and diastolic collapse of the right ventricle. She had a pericardiotomy done and 650mls of serous pericardial fluid was drained. The inner pericardium had a fibrinoid exudate with a "bread-and-butter" appearance. Pericardial fluid cytology showed no malignant cells while pericardial biopsy showed suppurative granulomatous inflammation. Antinuclear antibody (ANA) was strongly positive. The patient was managed with corticosteroids, colchicine, and hydroxychloroquine, and has remained stable on follow-up. While cardiac tamponade as an initial presenting complaint in SLE is rare, it is important that children presenting with large pericardial effusions and tamponade be evaluated for rheumatologic disorders. This can be crucial to revealing the correct diagnosis and instituting appropriate care.
ABSTRACT
A middle-aged gentleman presented with dyspnea and hypotension, accompanied by an anterior mediastinal mass infiltrating the anterior chest wall and a moderate to large pericardial effusion, which upon evaluation revealed chylous fluid. Further investigation diagnosed him with right lung adenocarcinoma infiltrating the chest wall, staged at T4N3M1. The patient subsequently developed cardiac tamponade, necessitating immediate medical intervention. Management of the patient's cardiac tamponade involved pericardiocentesis via an indwelling pericardial catheter, allowing continuous drainage of the chylous fluid. Additionally, the patient was placed on a medium-chain triglyceride diet (MCTD) to reduce chyle production. These interventions resulted in significant symptomatic improvement, stabilizing the patient's hemodynamic status, and alleviating the immediate life-threatening condition. This case highlights the clinical challenges posed by rare presentations such as chylopericardium secondary to malignancy and emphasizes the importance of comprehensive diagnostic evaluation and prompt therapeutic management. The successful outcome, achieved through a combination of pericardial drainage and dietary modifications, underscores the critical role of a conservative approach in managing complex oncological cases with acute complications.
ABSTRACT
We present an interesting and complex case of cardiac tamponade due to uremic pericarditis (UP), resolving with intensive hemodialysis (HD). HD should be considered as first line management for patients with UP and pericardial effusion. Intensification of HD should be considered based on clinical presentation and severity of presentation.
ABSTRACT
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
Pericarditis and pericardial effusion related to COVID-19 can lead to cardiac tamponade. Most case reports describe these complications in middle-aged or elderly patients. This case highlights a 29-year-old healthy patient who developed cardiac tamponade requiring an emergent pericardial window within one week of COVID-19 infection. This case also highlights the utility of point-of-care ultrasound in diagnosing serious COVID-19 complications.
ABSTRACT
Purulent pericarditis secondary to bacterial infections is rarely seen in the current era of broad-spectrum antibiotics. Complications tend to be higher in comparison to viral or idiopathic etiologies in cases of bacterial pericarditis. Staphylococcal aureus, Streptococcus pneumoniae, or Haemophilus influenza are the more commonly identified pathogens in cases of bacterial pericarditis. We report a case of purulent pericarditis from Bacteroides thetaiotaomicron and Streptococcus milleri occurring in conjunction in a 56-year-old male. To our knowledge, there are no published case reports describing purulent pericarditis from B. thetaiotaomicron and S. milleri occurring simultaneously in the literature.
ABSTRACT
Cardiac tamponade is a life-threatening occurrence with an incidence rate of about two out of 1,000 people. It is caused by the rapid accumulation of fluid in the pericardial sac. This can lead to the physical examination findings of tachycardia, hypotension, and elevated jugular venous pressure. Patients with chronic pericardial effusion are at increased risk for cardiac tamponade. We present a case of a patient with chronic, recurrent, malignant pericardial effusion that rapidly evolved to cardiac tamponade several hours from hospital presentation. We attempt to highlight the importance of close monitoring of patients who have recurrent chronic pericardial effusion in hopes of decreasing the number of patients who develop cardiac tamponade physiology.
ABSTRACT
In recent times, there has been a concerning rise in the incidence of sudden death among individuals in middle age. Predominantly, cardiovascular diseases emerge as the leading cause behind such untimely fatalities. Myocardial infarction and its subsequent complications stand out as the most frequently encountered scenarios in these tragic events. Despite being a relatively uncommon occurrence, cardiac tamponade represents one of the rare yet fatal complications that can ensue following a myocardial infarction. This condition manifests when the pericardial cavity becomes filled with either blood or blood clots, impeding the heart's normal functioning. Typically, patients experiencing cardiac tamponade are often reported to have succumbed to sudden death, with a preceding history of chest pain being a common indicator. The definitive diagnosis of cardiac tamponade usually occurs during post-mortem examinations. We consider the case of a 38-year-old man who was discovered unconscious at his residence and was pronounced dead upon arrival at the hospital. Subsequent autopsy findings unveiled the presence of both blood and blood clots within the pericardial cavity, in conjunction with a rupture in the right ventricle and occlusion of the left coronary artery. Histopathological analysis further confirmed the root cause of this tragic event as an acute myocardial infarction.
ABSTRACT
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: 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.
