Emergency Ultrasound Unveils Intermediate-High Risk Saddle Pulmonary Embolism with Extensive Bilateral Clot Burden, Masquerading as Micturition Syncope: A Case Report. J Emerg Med 2024; 66:e694-e700. [PMID: 38763838 DOI: 10.1016/j.jemermed.2024.01.018] [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: 11/29/2023] [Revised: 12/27/2023] [Accepted: 01/06/2024] [Indexed: 05/21/2024]
Abstract
BACKGROUND Isolated syncope as the manifestation of pulmonary embolism (PE) is a rare and diagnostically challenging presentation that often leads to delayed or missed diagnosis, increasing morbidity and mortality. In spite of emphasizing cardiovascular etiologies of syncope, current guidelines offer essentially no guidance in establishing a diagnostic workup for PE in these patients. By performing bedside echocardiography, emergency physicians can accurately identify concerning features suggestive of PE in patients with syncope. CASE REPORT A 78-year-old man, receiving ertapenem via a peripherally inserted central catheter for treatment of extended spectrum β-lactamase urinary tract infection, presented to the emergency department for isolated syncope with collapse while urinating. Arriving asymptomatic with normal vital signs and a benign physical examination, a presumptive diagnosis of micturition syncope was made. However, subtle vital sign changes on reassessment prompted performance of a point-of-care echocardiogram, which revealed signs of right heart strain. A computed tomography angiogram confirmed a saddle PE with extensive bilateral clot burden. Catheter-directed thrombectomy was performed via interventional radiology, with successful removal of pulmonary emboli. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Pulmonary embolism presenting as isolated syncope represents a daunting diagnostic dilemma, as emergency physicians may not consider it, or anchor on more benign etiologies of syncope. Although lacking sufficient sensitivity to rule out PE, point-of-care echocardiography to evaluate for signs of right heart strain can quickly and effectively point toward the diagnosis, while also assessing for other emergent cardiovascular causes of syncope. Given the lack of evidence-based guidance concerning PE presenting as syncope, bedside echocardiography should be highly considered as a part of the emergency physician's diagnostic workup, especially in patients with abnormal vital signs.

Alerhand S, Adrian RJ. What echocardiographic findings differentiate acute pulmonary embolism and chronic pulmonary hypertension? Am J Emerg Med 2023; 72:72-84. [PMID: 37499553 DOI: 10.1016/j.ajem.2023.07.011] [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: 05/08/2023] [Revised: 07/05/2023] [Accepted: 07/06/2023] [Indexed: 07/29/2023] Open
Abstract
BACKGROUND Pulmonary embolism (PE) and pulmonary hypertension (PH) are potentially fatal disease states. Early diagnosis and goal-directed management improve outcomes and survival. Both conditions share several echocardiographic findings of right ventricular dysfunction. This can inadvertently lead to incorrect diagnosis, inappropriate and potentially harmful management, and delay in time-sensitive therapies. Fortunately, bedside echocardiography imparts a few critical distinctions. OBJECTIVE This narrative review describes eight physiologically interdependent echocardiographic parameters that help distinguish acute PE and chronic PH. The manuscript details each finding along with associated pathophysiology and summarization of the literature evaluating diagnostic utility. This guide then provides pearls and pitfalls with high-quality media for the bedside evaluation. DISCUSSION The echocardiographic parameters suggesting acute or chronic right ventricular dysfunction (best used in combination) are: 1. Right heart thrombus (acute PE) 2. Right ventricular free wall thickness (acute ≤ 5 mm, chronic > 5 mm) 3. Tricuspid regurgitation pressure gradient (acute ≤ 46 mmHg, chronic > 46 mmHg, corresponding to tricuspid regurgitation maximal velocity ≤ 3.4 m/sec and > 3.4 m/sec, respectively) 4. Pulmonary artery acceleration time (acute ≤ 60-80 msec, chronic < 105 msec) 5. 60/60 sign (acute) 6. Pulmonary artery early-systolic notching (proximally-located, higher-risk PE) 7. McConnell's sign (acute) 8. Right atrial enlargement (equal to left atrial size suggests acute, greater than left atrial size suggests chronic). CONCLUSIONS Emergency physicians must appreciate the echocardiographic findings and associated pathophysiology that help distinguish acute and chronic right ventricular dysfunction. In the proper clinical context, these findings can point towards PE or PH, thereby leading to earlier goal-directed management.

Abstract
PURPOSE The purpose of this descriptive feasibility study was to assess the clinical impact and feasibility of conducting a multiorgan ultrasound examination of patients with pulmonary embolism at both time of diagnosis and at clinical follow-up. METHODS Hemodynamically stable patients with pulmonary embolism verified by CT pulmonary angiography or ventilation perfusion scintigraphy were eligible for inclusion. Enrolled patients underwent multiorgan ultrasound investigation encompassing echocardiography supplemented with focused lung and deep venous ultrasound emphasizing right ventricular strain, subpleural consolidations and presence of deep venous thrombi. Identical investigations were conducted at 3 months follow-up. The presence of ultrasonographic findings at diagnosis and follow-up was compared and the clinical impact of any remaining pathology or strain was described. RESULTS Twenty-one patients were enrolled in the study of whom 20 survived to attend follow-up. Mean age was 62 ± 15 years and 48% were female. At diagnosis, the most prevalent ultrasonographic findings were subpleural consolidations in 11 patients and right ventricular dilation in eight. At follow-up, signs of right ventricular strain had resolved in all patients. However, in one patient, no resolution was seen in a subpleural consolidation observed at the time of pulmonary embolism diagnosis, resulting in referral to a chest CT. Additionally, one patient exhibited residual deep venous thrombotic material, leading to prolongation of anticoagulative treatment. CONCLUSION In patients with pulmonary embolism, multiorgan ultrasound is feasible in follow-up and adequately powered studies should determine the clinical utility of such an approach.

Am J Emerg Med 2023; 68:52-58. [PMID: 36933334 DOI: 10.1016/j.ajem.2023.03.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 03/07/2023] [Accepted: 03/07/2023] [Indexed: 03/12/2023] Open
Abstract
OBJECTIVES Detecting reduced left ventricular ejection fraction (LVEF) by an emergency physician (EP) is an important skill. The subjective ultrasound assessment of LVEF by EPs correlates with comprehensive echocardiogram (CE) results. Mitral annular plane systolic excursion (MAPSE) is an ultrasound measure of vertical movement of the mitral annulus, which correlates to LVEF in the cardiology literature, but has not been studied when measured by an EP. Our objective is to determine whether EP measured MAPSE can accurately predict LVEF <50% on CE. METHODS This is a prospective observational single center study using a convenience sample to evaluate the use of a focused cardiac ultrasound (FOCUS) for patients with possible decompensated heart failure. The FOCUS included standard cardiac views to estimate LVEF, MAPSE, and E-point septal separation (EPSS). Abnormal MAPSE was defined as <8 mm and abnormal EPSS as >10 mm. The primary outcome assessed was the ability of an abnormal MAPSE to predict an LVEF <50% on CE. MAPSE also was compared to EP estimated LVEF and EPSS. Inter-rater reliability was determined by two investigators performing independent blinded review. RESULTS We enrolled 61 subjects, 24 (39%) had an LVEF <50% on a CE. MAPSE <8 mm had a 42% sensitivity (95% CI 22-63), 89% specificity (95% CI 75-97), and accuracy of 71% for detecting LVEF <50%. MAPSE demonstrated lower sensitivity than EPSS (79% sensitivity [95% CI 58-93], and 76% specificity [95% CI 59-88]) and higher specificity than estimated LVEF (100% sensitivity [95% CI 86-100], 59% specificity [95% CI 42-75]). PPV and NPV for MAPSE was 71% (95% CI 47-88) and 70% (95% CI 62-77) respectively. The ROC for MAPSE <8 mm is 0.79 (95% CI 0.68-0.9). MAPSE measurement interrater reliability was 96%. CONCLUSIONS In this exploratory study evaluating MAPSE measurements by EPs, we found the measurement was easy to perform with excellent agreement across users with minimal training. A MAPSE value <8 mm had moderate predictive value for LVEF <50% on CE and was more specific for reduced LVEF than qualitative assessment. MAPSE had high specificity for LVEF <50%. Further studies are needed to validate these results on a larger scale.

Abstract
Point-of-care ultrasound has been embraced by anaesthetists as an invaluable tool for rapid diagnosis of haemodynamic instability, to ensure procedural safety and monitor response to treatments. Increasingly available, affordable and portable, with emerging evidence of improved patient outcomes, point-of-care ultrasound has become a valuable tool in the emergency setting. This state-of-the-art review describes the feasibility of point-of-care ultrasound practice, training and maintenance of competence. It also describes the many uses of point-of-care ultrasound for the anaesthetist and describes the most salient point-of-care ultrasound views for anaesthetic emergencies including: undifferentiated shock; hypoxemia; and trauma. Procedural safety is also discussed in addition to relevant important governance aspects. Cardiac function should be assessed using the parasternal long axis, parasternal short basal/mid-papillary/apical, apical four chamber and subcostal four chamber views, and should include a visual estimation of global left ventricular ejection fraction. Other cardiovascular conditions that can be identified using point-of-care ultrasound include: pericardial effusion; cardiac tamponade; and pulmonary embolism. Pulmonary emergency conditions that can be diagnosed using point-of-care ultrasound include pneumothorax; pleural effusion; and interstitial syndrome. The extended focused assessment with sonography for trauma examination may of value in patients who are hypotensive in order to identify intra-abdominal haemorrhage, pneumothoraces and haemothoraces.

Abstract
Poor outcomes among the critically ill in low- and middle-income countries (LMICs) have been attributed in part to the challenge of diagnostic delays caused by lack of skilled personnel. Focused cardiac ultrasound (FoCUS) by non-cardiologists may mitigate the shortage of echocardiography experts to perform emergency echocardiography at the point of care in these settings. It is however crucial that FoCUS training for non-cardiologists in LMICs be based on robust evidence to support training delivery if diagnostic accuracy is to be assured.

Abstract
Abstract
Objectives
To describe the integration of point-of-care ultrasound (POCUS) and rotational thromboelastometry (ROTEM) in the diagnosis and management of cardiac arrest secondary to amniotic fluid embolism (AFE).
Case presentation
A 29-year-old female presented for induction of labor at 39 weeks. Labor was complicated by hemorrhage and subsequent sinus tachycardia pulseless electrical activity (PEA) arrest. Intra-arrest POCUS demonstrated right ventricular dilation and hypokinesis adding to a presumed hemorrhagic arrest etiology. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) was initiated at the bedside following the POCUS findings. ROTEM further clarified the etiology of hemorrhage as disseminated intravascular coagulation (DIC), and in combination with the POCUS findings led to a final diagnosis of amniotic fluid embolism with DIC. The patient was maintained on VA-ECMO without heparin in the setting of DIC. She had a complicated hospital course but was discharged home with her healthy child and no residual physical or neurologic deficits.
Conclusions
In the absence of more specific testing modalities the utilization of rapidly available POCUS in conjunction with ROTEM can impact clinical decision making of cardiovascular resuscitation in patients during labor and delivery by narrowing the differential between pulmonary embolism and AFE.

Abstract
OBJECTIVE To determine the diagnostic accuracy of point-of-care ultrasound in suspected pulmonary embolism. DESIGN Systematic review and meta-analysis. DATA SOURCES MEDLINE, Embase, CINAHL and Cochrane library were searched on 2 July 2020 with no restrictions on the date of publication. Subject headings or subheadings combined with text words for the concepts of pulmonary embolism, ultrasound and diagnosis were used. ELIGIBILITY CRITERIA AND DATA ANALYSIS Eligible studies reported sensitivity and specificity of deep venous, lung, cardiac or multiorgan ultrasound in patients with suspected pulmonary embolism, using an adequate reference-test. Prospective, cross-sectional and retrospective studies were considered for eligibility. No restrictions were made on language. Studies were excluded if a control group consisted of healthy volunteers or if transesophageal or endobronchial ultrasound was used. Risk of bias was assessed using quality assessment of diagnostic accuracy studies-2. Meta-analysis of sensitivity and specificity was performed by construction of hierarchical summary receiver operator curves. I2 was used to assess the study heterogeneity. MAIN OUTCOME MEASURES The primary outcome was overall sensitivity and specificity of reported ultrasound signs, stratified by organ approach (deep venous, lung, cardiac and multiorgan). Secondary outcomes were stratum-specific sensitivity and specificity within subgroups defined by pretest probability of pulmonary embolism. RESULTS 6378 references were identified, and 70 studies included. The study population comprised 9664 patients with a prevalence of pulmonary embolism of 39.9% (3852/9664). Risk of bias in at least one domain was found in 98.6% (69/70) of included studies. Most frequently, 72.8% (51/70) of studies reported >24 hours between ultrasound examination and reference test or did not disclose time interval at all. Level of heterogeneity ranged from 0% to 100%. Most notable ultrasound signs were bilateral compression of femoral and popliteal veins (22 studies; 4708 patients; sensitivity 43.7% (36.3% to 51.4%); specificity 96.7% (95.4% to 97.6%)), presence of at least one hypoechoic pleural-based lesion (19 studies; 2134 patients; sensitivity 81.4% (73.2% to 87.5%); specificity 87.4% (80.9% to 91.9%)), D-sign (13 studies; 1579 patients; sensitivity 29.7% (24.6% to 35.4%); specificity 96.2% (93.1% to 98.0%)), visible right ventricular thrombus (5 studies; 995 patients; sensitivity 4.7% (2.7% to 8.1%); specificity 100% (99.0% to 100%)) and McConnell's sign (11 studies; 1480 patients; sensitivity 29.1% (20.0% to 40.1%); specificity 98.6% (96.7% to 99.4%)). CONCLUSION Several ultrasound signs exhibit a high specificity for pulmonary embolism, suggesting that implementation of ultrasound in the initial assessment of patients with suspected pulmonary embolism may improve the selection of patients for radiation imaging.

Abstract
Since the advent of SARS-CoV-2, the virus that causes COVID-19, clinicians have had to modify how they provide high-value care while mitigating the risk of viral spread. Routine imaging studies have been discouraged due to elevated transmission risk. Patients who have been diagnosed with COVID-19 often have a protracted hospital course with progression of disease. Given the need for close follow-up of patients, we recommend the use of ultrasonography, particularly point-of-care ultrasound (POCUS), to manage patients with COVID-19 through their entire ICU course. POCUS will allow a clinician to evaluate and monitor cardiac and pulmonary function, as well as evaluate for thromboembolic disease, place an endotracheal tube, confirm central venous catheter placement, and rule out a pneumothorax. If a patient improves sufficiently to perform weaning trials, POCUS can also help evaluate readiness for ventilator liberation.

Abstract
Background and Objectives: bedside cardiac ultrasound is a widely adopted method in Emergency Departments (ED) for extending physical examination and refining clinical diagnosis. However, in the setting of hemodynamically-stable pulmonary embolism, the diagnostic role of echocardiography is still the subject of debate. In light of its high specificity and low sensitivity, some authors suggest that echocardiographic signs of right ventricle overload could be used to rule-in pulmonary embolism. In this study, we aimed to clarify the diagnostic role of echocardiographic signs of right ventricle overload in the setting of hemodynamically-stable pulmonary embolism in the ED. Materials and Methods: we performed a systematic review of literature in PubMed, Web of Science and Cochrane databases, considering the echocardiographic signs for the diagnosis of pulmonary embolism in the ED. Studies considering unstable or shocked patients were excluded. Papers enrolling hemodynamically stable subjects were selected. We performed a diagnostic test accuracy meta-analysis for each sign, and then performed a critical evaluation according to pretest probability, assessed with Wells' score for pulmonary embolism. Results: 10 studies were finally included. We observed a good specificity and a low sensitivity of each echocardiographic sign of right ventricle overload. However, once stratified by the Wells' score, the post-test probability only increased among high-risk patients. Conclusions: signs of echocardiographic right ventricle overload should not be used to modify the clinical behavior in low- and intermediate- risk patients according to Wells' score classification. Among high-risk patients, however, echocardiographic signs could help a physician in detecting patients with the highest probability of pulmonary embolism, necessitating a confirmation by computed tomography with pulmonary angiography. However, a focused cardiac and thoracic ultrasound investigation is useful for the differential diagnosis of dyspnea and chest pain in the ED.

Abstract
BACKGROUND Dyspnea is a common and often debilitating symptom with a complex diagnostic work-up. PURPOSE To evaluate the benefits, harms, and diagnostic test accuracy of point-of-care ultrasonography (POCUS) in patients with acute dyspnea. (PROSPERO: CRD42019126419). DATA SOURCES Searches of multiple electronic databases without language limitations (January 2004 to August 2020) and reference lists of pertinent articles and reviews. STUDY SELECTION Five randomized controlled trials (RCTs) and 44 prospective cohort-type studies in patients with acute dyspnea evaluated POCUS as a diagnostic tool to determine the underlying cause of dyspnea. Two investigators independently screened the literature for inclusion. DATA EXTRACTION Data abstraction by a single investigator was confirmed by a second investigator; 2 investigators independently rated risk of bias and determined certainty of evidence. DATA SYNTHESIS Point-of-care ultrasonography, when added to a standard diagnostic pathway, led to statistically significantly more correct diagnoses in patients with dyspnea than the standard diagnostic pathway alone. In-hospital mortality and length of hospital stay did not differ significantly between patients who did or did not receive POCUS in addition to standard diagnostic tests. Finally, POCUS consistently improved the sensitivities of standard diagnostic pathways to detect congestive heart failure, pneumonia, pulmonary embolism, pleural effusion, or pneumothorax; specificities increased in most but not all studies. LIMITATIONS Most studies assessed diagnostic test accuracy, which has limited utility for clinical decision making. Studies rarely reported on the proportion of indeterminate sonography results, and no evidence is available on adverse health outcomes of false-positive or false-negative POCUS results. CONCLUSION Point-of-care ultrasonography can improve the correctness of diagnosis in patients with acute dyspnea. PRIMARY FUNDING SOURCE American College of Physicians.

Abstract
INTRODUCTION Pulmonary embolism (PE) is a potentially fatal disease encountered in the hospital setting. Prompt diagnosis and management can improve outcomes and survival. Unfortunately, a PE may be difficult to diagnose in a timely manner. Point-of-care ultrasound (POCUS) can assist in the evaluation for suspected PE by assessing for acute right ventricular strain. Physicians should thus be aware of these echocardiographic findings. OBJECTIVE This manuscript will review ten echocardiographic findings of right ventricular strain that may suggest a diagnosis of PE. It will provide a description of each finding along with the associated pathophysiology. It will also summarize the literature for the diagnostic utility of echocardiography for this indication, while providing reference parameters where applicable. Along with labeled images and video clips, the review will then illustrate how to evaluate for each of the ten findings, while offering pearls and pitfalls in this bedside evaluation. DISCUSSION The ten echocardiographic findings of right ventricular strain are: increased right ventricle: left ventricle size ratio, abnormal septal motion, McConnell's sign, tricuspid regurgitation, elevated pulmonary artery systolic pressure, decreased tricuspid annular plane systolic excursion, decreased S', pulmonary artery mid-systolic notching, 60/60 sign, and speckle tracking demonstrating decreased right ventricular free wall strain. CONCLUSIONS Physicians must recognize and understand the echocardiographic findings and associated pathophysiology of right ventricular strain. In the proper clinical context, these findings can point toward a diagnosis of PE and thereby lead to earlier initiation of directed management.

Abstract
Introduction The 60/60 sign in 2D transthoracic echocardiography (TTE) - a combination of pulmonary acceleration time (PAT) less than 60 milliseconds and tricuspid regurgitation (TR) jet gradient of less than 60 mmHg - has been found to be specific for the diagnosis of pulmonary embolism (PE). Materials and methods An observational prospective analysis was carried out on cases of suspected PE presenting to the emergency room (ER). TTE was performed on all cases with suspected PE prior to computed tomography pulmonary angiography (CTPA). Emphasis was placed on measurement of PAT and early systolic notching (ESN) on the pulsed wave (PW) Doppler of the pulmonary valve, TR jet gradient, right ventricle systolic excursion velocity (RV S’) by tissue doppler imaging (TDI), tricuspid annular plane systolic excursion (TAPSE), and right ventricle to left ventricle end-diastolic dimension ratio (RV:LV EDD) in modified parasternal short-axis view. These signs were taken as screening tests and compared to CTPA as the standard test. Patients were followed up until hospital discharge or death. Observations Fifty-six cases of suspected PE were enrolled for the study. Of these, 24 cases of PE were confirmed by CTPA. Out of 24 cases of PE, 15 were high-risk PE, six were intermediate high-risk PE, and three were intermediate low-risk PE. The mean age was 53.07±9.79 years with a male-to-female ratio of 1.95:1. The 60/60 sign was present in 70.83% of cases of PE. RV:LV EDD in a modified short-axis view of more than 0.9 was present in 91.67% of cases of PE, and ESN on the PW Doppler of the pulmonary valve was present in 75% of cases of PE. The 60/60 sign, RV:LV EDD ratio more than 0.9, and ESN showed sensitivities of 70.83%, 91.67%, 75%, and specificities of 93.75%, 75%, and 100%, respectively for PE. For prediction of mortality, presence of the 60/60 sign (Odds Ratio=8.13, p-value=0.034) and ESN (Odds Ratio=17.50, p-value=0.02) were statistically significant. Conclusions 60/60 sign and ESN are specific for the diagnosis of PE but have poor sensitivity.

Abstract
The novel coronavirus SARS-CoV-2 (COVID-19) pandemic has created diagnostic uncertainty with regards to distinguishing this infection from pulmonary embolism (PE). Although there appears to be an increased incidence of thromboembolic disease in patients with COVID-19 infection, recommendations regarding anticoagulation are lacking. We present the case of a 61-year-old woman with clinically significant venous and arterial thromboemboli in the setting of COVID-19 infection requiring tissue plasminogen activator (tPA).

Abstract
The diagnosis of a right heart thrombus (RHTh) in transit associated with pulmonary embolism (PE) is an uncommon phenomenon with a high mortality rate. Timely recognition of RHTh with focused cardiac ultrasound (FOCUS) in cases of suspected PE is necessary for critical decision making in the emergency department (ED). We present a case of RHTh with submassive PE in which the patient underwent successful catheter-directed thrombolysis. This case report illustrates the significance of an emergency physician (EP) implementing FOCUS during the initial ED evaluation to rapidly diagnose RHTh in transit and initiate PE therapy without delay.

Abstract
Transthoracic echocardiography is the standard of care in anatomic and functional cardiovascular assessment; however, focused cardiac ultrasound (FoCUS) performed with portable ultrasound equipment is increasingly being used as an adjunct to comprehensive history and physical examination. FoCUS assessments, unlike formal echocardiography, are intended to assist physicians in answering explicit clinical questions with a narrow differential diagnosis in real time. Over the past decade, a growing body of literature has repeatedly shown the value that FoCUS adds to clinical evaluation. Specifically, FoCUS improves point-of-care diagnostic accuracy, which in turn modifies treatment plans, decreases time to diagnosis, and reduces resource utilization. Although less robust, there is also evidence showing improvement in clinical outcomes. Based on this evidence, clinicians, training programs, and clinical societies have embraced FoCUS as a tool to complement bedside patient evaluation. Herein, we review the evidence for FoCUS in clinical practice, specifically evaluating the diagnostic accuracy, the impact on clinical decision-making, and the effect on clinical outcomes.

Abstract
Patients with high-risk pulmonary embolism (PE) have a significant mortality rate, and thus a timely diagnosis and early treatment are essential to improve outcomes. Since these groups of patients are often too ill to be transferred to the radiology department to perform a chest computed tomography angiography, offering a feasible, reliable and bedside diagnostic tool may be desirable in this setting. We report the case of a middle-aged woman presenting to the emergency department with shock who was diagnosed with massive pulmonary embolism based on point-of-care ultrasound (POCUS). We are hereby discussing the usefulness of POCUS in this subset of PE patients, highlighting the importance of considering ultrasound as a first-line diagnostic (and monitoring) tool for each patient with suspicion of massive PE.

Abstract
INTRODUCTION The imaging standard for evaluation of acute pulmonary embolism (PE) includes a computed tomography pulmonary angiogram. Ultrasonography has shown promise in obtaining the tricuspid annular plane systolic excursion (TAPSE) measurements, which may be of clinical importance in patients with acute PE. The objective of this study is to evaluate the diagnostic capability of TAPSE measurements for patients with suspicion for acute PE. METHODS We prospectively enrolled patients who came to the emergency department with suspicion of acute PE. Each patient underwent a point-of-care sonogram where a TAPSE measurement was obtained, followed by computed tomography pulmonary angiogram. Based on the computed tomography pulmonary angiogram findings, patients were grouped into 3 categories: no acute PE, clinically insignificant acute PE, or clinically significant acute PE. RESULTS We enrolled 87 patients in this study. Twenty-three (26.4%) of these patients were diagnosed with PE. Of patients with PE, 15 (65%) were found to have a clinically significant acute PE. Analysis of mean TAPSE measurements between patients with clinically significant acute PE and those with insignificant or no PE was 15.2 mm and 22.7 mm, respectively (P ≤ .0001). Following receiver operating characteristic curve analysis, optimum TAPSE measurement to identify clinically significant acute PE is 18.2 mm. A cutoff TAPSE measurement of 15.2 mm shows a sensitivity of 53.3% (95% confidence interval, 26.7%-80%) and a specificity of 100% (95% confidence interval, 100%-100%) for the diagnosis of a clinically significant PE. CONCLUSIONS Our data suggest that TAPSE measurements less than 15.2 mm have a high specificity for identifying clinically significant acute PE.
