Abstract
Intensive care physicians may assume the primary care of patients with transplant-associated thrombotic microangiopathy (TA-TMA), an uncommon but potentially critical complication of hematopoietic stem cell transplants (HSCTs) and solid organ transplants. TA-TMA can have a dramatic presentation with multiple organ dysfunction syndrome (MODS) associated with high morbidity and mortality. The typical presenting clinical features are hemolytic anemia, thrombocytopenia, refractory hypertension, proteinuria and worsening renal failure. Intestinal involvement, with abdominal pain, nausea and vomiting, gastrointestinal bleeding, and ascites are also common. Cardiopulmonary involvement may develop from various causes including pulmonary arteriolar hypertension, pleural and pericardial effusions, and diffuse alveolar hemorrhage. Due to other often concurrent complications after HSCT, early diagnosis and effective management of TA-TMA may be challenging. Close collaboration between ICU and transplant physicians, along with other relevant specialists, is needed to best manage these patients. There are currently no approved therapies for the treatment of TA-TMA. Plasma exchange and rituximab are not recommended unless circulating factor H (CFH) antibodies or thrombotic thrombocytopenic purpura (TTP; ADAMTS activity < 10%) are diagnosed or highly suspected. The role of the complement pathway activation in the pathophysiology of TA-TMA has led to the successful use of targeted complement inhibitors, such as eculizumab. However, the relatively larger studies using eculizumab have been mostly conducted in the pediatric population with limited data on the adult population. This review is focused on the role of intensive care physicians to emphasize the clinical approach to patients with suspected TA-TMA and to discuss diagnosis and treatment strategies.

J Emerg Med 2024; 66:e346-e353. [PMID: 38281857 DOI: 10.1016/j.jemermed.2023.10.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 10/18/2023] [Accepted: 10/22/2023] [Indexed: 01/30/2024]
Abstract
BACKGROUND Cardiac tamponade is associated with high mortality, and making the diagnosis is a core skill of emergency physicians. Proper diagnosis relies on specific clinical and echocardiographic findings. It is not known whether expert sonographers consistently recognize echocardiographic signs of tamponade. OBJECTIVES To assess whether expert sonographers agree on echocardiographic signs of tamponade. METHODS A 20-question survey consisting of 18 cine loops and 2 still images was distributed to the Academy of Emergency Ultrasound Section of the Society for Academic Emergency Medicine. Respondents answered "yes" or "no" to whether there was echocardiographic evidence of tamponade. Subgroup analyses of demographics and echocardiographic views were reported. The data were analyzed using Krippendorff's alpha (α) to assess interrater reliability (IRR) between respondents. RESULTS Eighty-four physicians responded and 56 completed the survey. All partial and completed surveys were analyzed. The overall IRR was poor (α = 0.60, 95% confidence interval [CI] 0.44-0.76). Residency graduation within 5 years (α = 0.66, 95% CI 0.5-0.8) was associated with higher IRR compared with those > 5 years (α = 0.53, 95% CI 0.37-0.69). The highest IRR was observed when images of mitral valve inflow pulse-wave Doppler (α = 0.81, CI 0.70-0.92) were used and the poorest IRR was on images from the parasternal short view (α = 0.28, 95% CI 0.05-0.49). CONCLUSION There was poor agreement among expert emergency medicine sonographers in identifying echocardiographic signs of cardiac tamponade from a single cine loop or clip without clinical context. Further investigation is warranted to understand differences in recognition of clinical tamponade.

Abstract
STUDY OBJECTIVE Cardiac tamponade is an impending calamitous disorder that emergency physicians need to consider and diagnose rapidly. A pericardial effusion with right atrial systolic collapse (earliest sign) or right ventricular diastolic collapse (most specific sign) and a plethoric inferior vena cava are indicators of cardiac tamponade physiology and may be identified with point-of-care ultrasonography (POCUS). The goal of this study is to assess the agreement among emergency physicians with varying levels of sonographic training and expertise in interpreting echocardiographic signs of cardiac tamponade in adult patients. Methods: Emergency physicians at different levels of training as sonographers were surveyed at didactic conferences at three major academic medical centers in northern New Jersey. Two cardiologists were also included in the study for comparison. Survey respondents were shown 15, 20-second video clips of patients who had presented to the emergency department (ED) with or without significant pericardial effusions and were asked to rate whether tamponade physiology was present or not. Data were collected anonymously on Google Forms (Google LLC, Mountain View, CA) and included self-reported levels of POCUS expertise and level of training. Data were analyzed using Fleiss' kappa (k). All patients had an echocardiogram performed by the department of cardiology within 24 hours of the POCUS, and the results are presented in the paper. Results: There were 97 participant raters, including attendings, fellows, and resident physicians specializing in adult emergency medicine and two cardiologists. There was a fair degree of inter-rater agreement among all participants in interpreting whether tamponade physiology was present or not. This low level of agreement persisted across self-reported training levels and self-reported POCUS expertise, even at the expert level in both emergency medicine and cardiology specialties. CONCLUSION According to the results of our study, there appears to be a low level of agreement in the interpretation of cardiac tamponade in adult patients. The lack of agreement persisted across specialties, self-reported training levels, and self-reported ultrasonographic expertise. This low level of agreement seen among both specialists indicates that emergency physicians are not limited in their ability to determine cardiac tamponade on POCUS. This highlights the technical nature of POCUS clips and strengthens the importance of physical exam findings when diagnosing cardiac tamponade in emergency department patients. Further research utilizing POCUS for the diagnosis of tamponade is warranted.

Abstract
We sought to determine the cardiac ultrasound view of greatest quality using a machine learning (ML) approach on a cohort of transthoracic echocardiograms (TTE) with abnormal left ventricular (LV) systolic function. We utilize an ML model to determine the TTE view of highest quality when scanned by sonographers. A random sample of TTEs with reported LV dysfunction from 09/25/2017-01/15/2019 were downloaded from the regional database. Component video files were analyzed using ML models that jointly classified view and image quality. The model consisted of convolutional layers for extracting spatial features and Long Short-term Memory units to temporally aggregate the frame-wise spatial embeddings. We report the view-specific quality scores for each TTE. Pair-wise comparisons amongst views were performed with Wilcoxon signed-rank test. Of 1,145 TTEs analyzed by the ML model, 74.5% were from males and mean LV ejection fraction was 43.1 ± 9.9%. Maximum quality score was best for the apical 4 chamber (AP4) view (70.6 ± 13.9%, p<0.001 compared to all other views) and worst for the apical 2 chamber (AP2) view (60.4 ± 15.4%, p<0.001 for all views except parasternal short-axis view at mitral/papillary muscle level, PSAX M/PM). In TTEs scanned by professional sonographers, the view with greatest ML-derived quality was the AP4 view.

Abstract
Perioperative transesophageal echocardiography (TEE) has been part of clinical activity for more than 40 years. During this period, TEE has evolved in terms of technology and clinical applications beyond the initial fields of cardiology and cardiac surgery. The benefits of TEE in the diagnosis and management of acute hemodynamic and respiratory collapse have been recognized in noncardiac surgery and by other specialties too. This natural progress led to the development of rescue TEE, a relatively recent clinical application that extends the use of TEE and makes it accessible to a large group of clinicians and patients requiring acute care. In this review, the authors appraise the current clinical applications and evidence base around this topic. The authors provide a thorough review of the various image acquisition protocols, clinical benefits, and compare it with the more frequently used transthoracic echocardiography. Furthermore, the authors have reviewed the current training and credentialing pathways. Overall, rescue TEE is a highly attractive and useful point-of-care examination, but the current evidence base is limited and the technical protocols, training, and credentialing processes are not standardized. There is a need for adequate guidelines and high-quality research to support its application as a bedside rescue tool.

Abstract
BACKGROUND Critical care transesophageal echocardiography (ccTEE) is an increasingly popular tool used by intensivists to characterize and manage hemodynamics at the bedside. Its usage appears to be driven by expanded diagnostic scope as well as the limitations of transthoracic echocardiography (TTE) - lack of acoustic windows, patient positioning, and competing clinical interests (eg, the need to perform chest compressions). The objectives of this scoping review were to determine the indications, clinical impact, and complications of ccTEE. METHODS MEDLINE, EMBASE, Cochrane, and six major conferences were searched without a time or language restriction on March 31st, 2021. Studies were included if they assessed TEE performed for adult critically ill patients by intensivists, emergency physicians, or anesthesiologists. Intraoperative or post-cardiac surgical TEE studies were excluded. Study demographics, indication for TEE, main results, and complications were extracted in duplicate. RESULTS Of the 4403 abstracts screened, 289 studies underwent full-text review, with 108 studies (6739 patients) included. Most studies were retrospective (66%), performed in academic centers (84%), in the intensive care unit (73%), and were observational (55%). The most common indications for ccTEE were hemodynamic instability, trauma, cardiac arrest, respiratory failure, and procedural guidance. Across multiple indications, ccTEE was reported to change the diagnosis in 52% to 78% of patients and change management in 32% to79% patients. During cardiac arrest, ccTEE identified the cause of arrest in 25% to 35% of cases. Complications of ccTEE included two cases of significant gastrointestinal bleeding requiring intervention, but no other major complications (death or esophageal perforation) reported. CONCLUSIONS The use of ccTEE has been described for the diagnosis and management of a broad range of clinical problems. Overall, ccTEE was commonly reported to offer additional diagnostic yield beyond TTE with a low observed complication rate. Additional high quality ccTEE studies will permit stronger conclusions and a more precise understanding of the trends observed in this scoping review.

Abstract
AIMS To evaluate the evidence and produce a summary and recommendations for the most common heart and lung applications of point-of-care ultrasound (PoCUS). METHODS We reviewed 10 clinical domains/questions related to common heart and lung applications of PoCUS. Following review of the evidence, a summary and recommendation were produced, including assignment of levels of evidence (LoE) and grading of the recommendation, assessment, development, and evaluation (GRADE). 38 international experts, the expert review group (ERG), were invited to review the evidence presented for each question. A level of agreement of over 75 % was required to progress to the next section. The ERG then reviewed and indicated their level of agreement regarding the summary and recommendation for each question (using a 5-point Likert scale), which was approved if a level of agreement of greater than 75 % was reached. A level of agreement was defined as a summary of "strongly agree" and "agree" on the Likert scale responses. FINDINGS AND RECOMMENDATIONS One question achieved a strong consensus for an assigned LoE of 3 and a weak GRADE recommendation (question 1). The remaining 9 questions achieved broad agreement with one assigned an LoE of 4 and weak GRADE recommendation (question 2), three achieving an LoE of 3 with a weak GRADE recommendation (questions 3-5), three achieved an LoE of 3 with a strong GRADE recommendation (questions 6-8), and the remaining two were assigned an LoE of 2 with a strong GRADE recommendation (questions 9 and 10). CONCLUSION These consensus-derived recommendations should aid clinical practice and highlight areas of further research for PoCUS in acute settings.

Abstract
OBJECTIVES Pericardial effusion is a rare clinical manifestation in idiopathic inflammatory myopathies (IIMs). It has been described in a small number of literature studies worldwide. We describe the clinical and laboratory characteristics of 19 IIM patients combined with pericardial effusion, and compare them with previously reported cases. The single-center observational-study-inspired collected of 156 IIM patients with complete data from January 1, 2016 to January 1, 2021 in the First Affiliated Hospital of Xinjiang Medical University, of which 19 patients had pericardial effusion. METHODS The clinical characteristics of 19 IIM patients complicated with pericardial effusion were investigated by descriptive analysis and compared with previously reported cases. RESULTS 19 cases of IIM patients had pericardial effusion (12.2%), patients without a large amount of pericardial effusion or pericardial tamponade. There was a predominance of women in the patients with 78.9% pericardial effusion . In the clinical examination, 10 cases showed chest tightness (52.6%), pulmonary fibrosis (47.4%), and the frequency of muscle nuclear magnetic, which suggested that muscle lymphocyte infiltration rate was 63.2%. Anti-Ro-52 antibody and anti-Jo-1 antibody were positive (26.3%, 42.1%). IIM patients with pericardial effusion were accompanied by decreased serum albumin levels and elevated ESR. In the literature review, the most common clinical characteristics of IIM patients with pericardial effusion were female, pulmonary fibrosis, shortness of breath, positive anti-Ro-52 pulmonary fibrosis, and anti-Jo-1 antibody. CONCLUSION In the study, 19 patients of IIMs with pericardial effusion present with chest tightness, and are accompanied by pulmonary fibrosis, positive anti-Jo-1 antibody, and anti-Ro-52 antibody. It is suggested that pericardial effusion in IIM patients may be related to anti-synthetase antibody.

Abstract
The physical exam is changing. Many have argued that the physical exam of the 21st century should include point-of-care ultrasound (POCUS). POCUS is being taught in medical schools and has been endorsed by the major professional societies of internal medicine. In this review we describe the trend toward using POCUS in medicine and describe where the practicing nephrologist fits in. We discuss what a nephrologist's POCUS exam should entail and we give special attention to what nephrologists can gain from learning POCUS. We suggest a 'nephro-centric' approach that includes not only ultrasound of the kidney and bladder, but of the heart, lungs and vascular access. We conclude by reviewing some of the sparse data available to guide training initiatives and give suggested next steps for advancing POCUS in nephrology.

Abstract
OBJECTIVES To determine the association between emergency department point-of-care cardiac ultrasonography (POCUS) utilization and time to pericardial effusion drainage during an 8-year period when the emergency ultrasound program was established at our institution. METHODS We performed a single-center retrospective cohort study in patients undergoing pericardiocentesis or other procedure for evacuation of pericardial effusion. Data was collected using both direct queries to the electronic health record database and two-examiner chart review. The primary outcome was time to intervention for pericardial effusion drainage. Multivariable Cox regression, with and without inverse probability weighting for likelihood to receive POCUS, was used to determine the association between POCUS and time to intervention. Secondary outcomes included 28-day mortality. RESULTS 257 patient encounters were included with 137 receiving POCUS and 120 who did not. The proportion of patients receiving POCUS increased from 18.5% to 69.5% during the early to late periods of the study. POCUS was associated with an earlier median time to intervention of 21.6 h (95% CI 17.2, 24.2) compared to 34.6 h (27.0, 50.5) in the No POCUS group. After adjustment for patient demographics, anticoagulation, time of presentation and hemodynamic instability, POCUS was associated with earlier intervention (HR 2.08 [95% CI 1.56, 2.77]). POCUS use was not associated with a difference in 28-day mortality, which was evaluated as a secondary outcome. However, diagnosis of pericardial effusion by the ED physician using any means (POCUS or other imaging) was associated with decreased 28-day mortality (9.7% vs. 26.0%, -16.3% for POCUS [95% CI -29.1, -3.5]). CONCLUSION POCUS was associated with an earlier time to intervention for pericardial effusions after adjustment for multiple confounding factors. Failure to diagnose pericardial effusion in the ED using any diagnostic testing including POCUS, was associated with increased 28-day mortality.

Abstract
POCUS is increasingly being used in the evaluation of critically ill patients. POCUS can shorten pulse check duration and prognosticate outcomes in cardiac arrest. POCUS can identify the etiology of cardiac arrest after the first image. POCUS can be used without delay or interrupting treatment.

Abstract
Limited views are often obtained in the setting of cardiac ultrasound, however, the likelihood of missing left ventricular (LV) dysfunction based on a single view is not known. We sought to determine the echo views that were least likely to miss LV systolic dysfunction in consecutive transthoracic echocardiograms (TTEs). Structured data from TTEs performed at 2 hospitals from September 25, 2017, to January 15, 2019, were screened. Studies of interest were those with reported LV dysfunction. Views evaluated were the parasternal long-axis (PLAX), parasternal-short axis at mitral (PSAX M), papillary muscle (PSAX PM), and apical (PSAX A) levels, apical 2 (AP2), apical 3 (AP3), and apical 4 (AP4) chamber views. The probability that a view contained at least 1 abnormal segment was determined and analyzed with McNemar's test for 21 adjusted pair-wise comparisons. There were 4102 TTE studies included for analysis. TTEs on males comprised 72.7% of studies with a mean LV ejection fraction of 42.8 ± 9.7%. The echo view with the greatest likelihood of encompassing an abnormal segment was the AP2 view with a prevalence of 93.4% (p < 0.001, compared to all other views). The PLAX view performed the worst with a prevalence of 82.5% (p < 0.015, compared to all other views). The best parasternal view for the detection of abnormality was the PSAX PM view at 90.4%. In conclusions, a single echo view will contain abnormal segments > 82% of the time in the setting of LV systolic dysfunction, with a prevalence of up to 93.4% in the apical windows.

Abstract
Permanent pacemaker (PPM) insertion is widely used to treat cardiac rhythm disorders; approximately 600,000 pacemakers are implanted annually in the US (Wood and Ellenbogen, 2002). Almost 9% of patients who receive a permanent pacemaker, however, experience a variety of medical complications such as infections, battery problems, programming issues, lead migration, or lead fracture (Greenspon et al., 2012). Moreover 1-2% of these patients will encounter severe lead-related problems within 30 days of their pacemaker insertion (Kirkfeldt et al., 2014; Kiviniemi et al., 1999). In this report, we focus on an uncommon but serious complication of PPM insertion: right ventricular lead perforation leading to a pericardial effusion. Although lead perforation is a relatively rare occurrence, this event can be life-threatening, and should be considered in the differential diagnosis when patients present to the emergency department (ED) with relevant symptoms and recent PPM insertion. Specifically, patients who experience complications from pacemaker insertion may present to the ED with a variety of symptoms such as chest pain, syncope, dyspnea, or even dizziness (Squire and Niemann, 2006). Pacemaker complications include pneumothorax, pleural and/or pericardial effusions, and infection, placing the patient at serious risk for significant harm (Squire and Niemann, 2006; Shingaki et al., 2015). The evaluation of a lead-related issue typically involves chest radiography to visualize abnormal lead placement and check for a pneumothorax or pleural effusion, and a 12‑lead electrocardiogram (ECG) to detect pacing errors. We present the case of a patient who presented to the ED three days after his pacemaker insertion with chest pain and dyspnea; he was subsequently diagnosed with a lead perforation into the pericardial space resulting in a pericardial effusion.
