Reproducibility and accuracy of a pocket-size ultrasound device in assessing liver steatosis. Dig Liver Dis 2024; 56:1032-1038. [PMID: 38016894 DOI: 10.1016/j.dld.2023.11.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 11/07/2023] [Accepted: 11/09/2023] [Indexed: 11/30/2023]
Abstract
BACKGROUND This diagnostic prospective study compared the feasibility and diagnostic accuracy of Pocket-size Ultrasound Devices (PUDs) against standard ultrasound (US) in detecting liver steatosis using the controlled attenuation parameter (CAP) and liver biopsy as reference standards. MATERIALS AND METHODS Consecutive patients with chronic liver diseases were assessed for the presence of steatosis using PUD and US. A CAP cut-off value >275 dB/m was applied to establish ≥S1. A 26-patient subgroup underwent liver biopsy. PUD reproducibility was evaluated using Cohen's k statistic. Diagnostic accuracy of PUD and US was given as Sensibility (Sn), Specificity (Sp), Positive and Negative Predictive Values (PPV, NPV), positive and negative Likelihood Ratio (LR+, LR-). RESULTS 81 consecutive patients (69% males) with multiple etiologies were enroled. PUD inter-observer agreement was good (k 0.77, 95%CI 0.62-0.93). PUD and US identified ≥S1 according to CAP values respectively with Sn 0.87, Sp 0.61, PPV 0.49, NPV 0.91, LR+ 2.04, LR- 0.07, AUROC 0.74 and Sn 0.96, Sp 0.54, PPV 0.47, NPV 0.97, LR+ 2.10, LR- 0.07, AUROC 0.75. CONCLUSIONS PUD shows good reproducibility and diagnostic accuracy in ruling liver steatosis out, representing a useful point-of-care tool to avail of hepatologists interested in excluding NAFLD, but with basic US skills.

The Point-of-Care Ultrasound (POCUS) by the Handheld Ultrasound Devices (HUDs) in the COVID-19 Scenario: a Review of the Literature. SN COMPREHENSIVE CLINICAL MEDICINE 2022; 5:1. [PMID: 36407770 PMCID: PMC9665043 DOI: 10.1007/s42399-022-01316-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 10/18/2022] [Indexed: 06/10/2023]
Abstract
The use of portable ultrasound (US) devices is increasing, due to its accessibility, versatility, non-invasiveness, and its significant support in the patient management, extending the traditional physical examination through the POCUS (point-of-care ultrasound). The pocket-size or handheld ultrasound devices (HUDs) can easily perform focused exams, not aiming to substitute for the high-end US systems (gold standard), since the HUDs usually have more limited functions. The HUDs are promising tools for the diagnosis, prognosis, and monitoring of the COVID-19 infection and its related disorders. In conclusion, the routine use of HUDs may ameliorate the management of COVID-19 pandemic, according to the guidelines for the POCUS approach and the procedures for the protection of the patients and the professionals.

Abstract
Trends of medical system move from a traditional in-person visit to virtual healthcare increases demands on point-of-care devices. Because ultrasound (US) is non-invasive, the demands highlight US imaging among other imaging modalities. Thanks to the development of US transducer technology, miniaturized US with application-specific integrated circuits (ASIC) have been researched. For example, applications that require small aperture sizes such as intravascular US (IVUS) and intra-cardiac echocardiography (ICE) require integration of system-on-a-chip (SoC) on the transducer. This paper reviews circuit techniques on the transmitter (TX) and receiver (RX) of the US imaging system. As TX circuits, pulser, T/RX switch, TX beamformer, and power management circuits are discussed. State-of-the-art transducer modeling, pre-amplifier, time-gain compensation, RX beamformer, quadrature sampler, and output driver are introduced as RX circuits.

Abstract
BACKGROUND The purpose of this study was to assess the utility of a handheld device (HH) used during common daily practice and its agreement with the results of a standard echocardiography study (STD) performed by experienced sonographers and echocardiographer. METHODS A prospective follow-up was conducted in an adult outpatient echocardiography clinic. Experienced sonographers performed the STD and an experienced echocardiographer performed the HH. STD included 2-dimensional images, Doppler and hemodynamics analysis. Hemodynamic assessment was not performed with the HH device because the HH does not include such technology. The images were interpreted by blinded echocardiographers, and the agreement between the reports was analyzed. RESULTS A total of 108 patients were included; and the concordance for left ventricle (LV) ejection fraction (EF), wall motion score index, LV and right ventricle (RV) function, RV size, and mitral and aortic stenosis was excellent with κ values greater than 0.80. Wall motion abnormalities had good concordance (κ value 0.78). The agreement for LV hypertrophy, mitral and aortic regurgitation was moderate, and tricuspid and pulmonary regurgitation agreements were low (κ values of 0.26 and 0.25, respectively). CONCLUSIONS In a daily practice scenario with experienced hands, HH demonstrated good correlation for most echocardiography indications, such as ventricular size and function assessment and stenosis valve lesion analyses.

Abstract
IMPORTANCE There are accumulating data about the utility of diagnostic multiorgan focused clinical ultrasonography (FCU) in the assessment of patients admitted with cardiopulmonary symptoms. OBJECTIVE To determine whether adding multiorgan FCU to the initial clinical evaluation of patients admitted with cardiopulmonary symptoms reduces hospital length of stay, hospital readmissions, and in-hospital costs. DESIGN, SETTING, AND PARTICIPANTS This is a prospective, parallel-group, superiority, randomized clinical trial with a 1:1 allocation ratio. The study was conducted at The Royal Melbourne Hospital, a tertiary public hospital located in Melbourne, Victoria, Australia. Adults aged 18 years or older admitted to the internal medicine ward with a cardiopulmonary diagnosis were enrolled between September 2018 and December 2019 and were followed up until hospital discharge. Data analysis was performed from August 2020 to January 2021. INTERVENTIONS The intervention involved an internal medicine physician-performed heart, lung, and 2-point vein compression FCU in addition to standard clinical evaluation. MAIN OUTCOMES AND MEASURES The primary outcome was the difference in the mean length of hospital stay, defined as the number of hours from admission to the internal medicine ward to hospital discharge. A difference of 24 hours was defined as clinically important. Secondary outcomes included hospital readmissions at 30 days and hospital care costs. RESULTS A total of 250 participants were enrolled and 2 were excluded, leaving 248 participants (mean [SD] age, 80.1 [11.0] years; 121 women [48.7%]) in the final analysis. There were 124 patients in the intervention group and 124 patients in the control group. The most common initial diagnoses were acute decompensated heart failure (113 patients [45.5%]), pneumonia (45 patients [18.1%]), and exacerbated chronic pulmonary disease (32 patients [12.9%]). The length of hospital stay was 113.4 hours (95% CI, 91.7-135.1 hours) in the FCU group and 125.3 hours (95% CI, 101.7-148.8 hours) in the control group (P = .53). The 30-day readmission rate was not different between groups (FCU vs control, 20 of 124 patients [16.1%] vs 15 of 124 patients [12.0%]), nor were total in-hospital costs (FCU vs control, A$7831.1 [95% CI, A$5586.1-A$10 076.1] vs A$7895.7 [95% CI, A$6385.9-A$9.405.5]). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, adult patients admitted to an internal medicine ward with a cardiopulmonary diagnosis, who underwent multiorgan FCU of the heart, lungs, and lower extremities veins during their initial clinical assessment, did not have a shorter hospital length of stay by more than 24 hours, compared with patients who received standard care.

Abstract
Introduction The aim of this study is to compare three different echocardiographic methods commonly used in the assessment of left ventricle (LV) ejection fraction (EF). Methods All patients underwent full echocardiography including LVEF assessed using M-mode, automated EF (Auto-EF), and visual estimation by two readers. Results We enrolled 268 patients. Auto-EF measurement was feasible in 240 (89.5%) patients. The averaged LVEF was (52% ± 12) with the visual assessment, (51% ± 11) with Auto-EF and (57% ± 13) with M-mode. Using Bland-Altman analysis, we found that the difference between the mean visual and the Auto-EF was not significant (-0.3% [-0.5803-0.0053], P = 0.054). However, the mean EF was significantly different when comparing visual versus M-mode and Auto-EF versus M-mode with the mean differences: (-2.4365 [-2.9946--1.8783], P < 0.0001) and (-2.1490 [-2.7348--1.5631], P < 0.0001) respectively. Inter-observer variability analysis of the visual EF assessment between the two readers showed that intraclass correlation coefficient was 0.953, (95% confidence interval: 0.939-0.965, P < 0.0001), with excellent correlation between the two readers: R = 0.911, P < 0.0001). Conclusion The two-dimensional echocardiographic methods using Biplane Auto-EF or visual assessment were significantly comparable, whereas M-mode results in an overestimation of the LVEF.

Abstract
BACKGROUND Point-of-care ultrasonography (PoCUS) is increasingly used across the medical field. PoCUS is also being implemented in general practice despite a lack of clinical guidelines and training programs for general practitioners (GPs). OBJECTIVES This study aimed to elucidate the employment of PoCUS by Danish GPs following a short training program. METHODS Thirty GPs were enrolled in a short ultrasound training program and taught how to perform 22 selected scanning modalities. In the following 3 months, the GPs registered all performed PoCUS examinations according to the Audit Project Odense method. After 5 months, the GPs were invited to participate in an evaluation seminar, where questionnaires were distributed. RESULTS During the registration period, 1598 patients were examined with PoCUS. A total of 1948 scanning modalities were registered, including 207 examinations outside the taught curriculum. The majority of the ultrasound examinations were performed within 10 minutes (89%), most were considered to be conclusive (87%) and/or to increase diagnostic certainty (67%), whereas one in four examinations entailed a change in patient management. Most GPs attending the evaluation seminar continued to use PoCUS and found the scanning modalities included in the course curriculum relevant in their daily work. CONCLUSION The GPs found several indications for performing PoCUS following the attendance of a 2-day basic training program. The majority of examinations were registered to be conclusive and/or increase diagnostic certainty. However, few GPs used PoCUS on a daily basis and not all examinations were registered to have an impact on patient care.

[PMID: 33775533 DOI: 10.1016/j.jfma.2021.02.021] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Revised: 02/18/2021] [Accepted: 02/25/2021] [Indexed: 10/21/2022] Open
Abstract
PURPOSE The ultrasound applications, examination facilities and methods used by otolaryngology and head and neck surgeons may vary and be different. This study was conducted to assess the methods used for head-and-neck point-of-care ultrasound (POCUS). METHODS This prospective survey study was conducted from 1 July 2018 to 31 December 2019. The surgeons of otolaryngology and head neck surgery who used POCUS in their daily practice were recruited for analyses. RESULTS In total, 30 male and 14 female surgeons who used neck POCUS were recruited. Thirty-nine (89%) surgeons placed patients in a supine position with the head toward the operator. Forty (91%) surgeons performed US-guided fine needle aspiration (FNA), and 35 (80%) surgeons did not use local anesthesia during US-FNA. Thirty-nine (88%) surgeons used the long-axis method to harvest the specimen, and forty-one (93%) used a free-hand method. Most surgeons (25, 57%) used 22G needles for US-FNA, and 29 (66%) used 18G for US-guided core-needle biopsy (CNB). For the cost analysis, reimbursements for US-related procedures were relatively cheaper than those for computer tomography (CT) and magnetic resonance imaging (MRI). CONCLUSION POCUS can be performed by otolaryngology and head and neck specialists with a wide scope of applications and in a cost-effective manner.

Abstract
Inflammatory bowel diseases [IBD], including Crohn's disease [CD] and ulcerative colitis [UC], are chronic, relapsing and destructive inflammatory disorders of the gastrointestinal tract which can lead to organ damage and impair quality of life. A 'treat-to-target' strategy based on activity and severity of disease and response to treatment with close monitoring of intestinal inflammation is recommended. Ileocolonoscopy [CS] is considered the first-line procedure for the assessment of IBD, and magnetic resonance enterography [MRE] is the current standard for assessing the small bowel and complications in CD, and has been proposed as an alternative procedure to CS in the evaluation of both ileo-colonic CD and UC. As that both CS and MRE are invasive and expensive procedures and unappealing to patients, they are unfeasible as frequent and repetitive tools for the monitoring of disease activity. Bowel ultrasound [US] represents a well-tolerated, non-invasive and cost-effective modality to manage IBD patients in clinical practice. Compared to CS and MRE, bowel US has been shown to have the same level of accuracy in assessing and monitoring disease activity and severity of both CD and UC. It can be performed at the point-of-care and therefore allow for real-time clinical decision-making. Point-of-care ultrasound [POCUS] is suggested as the stethoscope of the future and is gaining interest and diffusion in the medical field because it can be used for the bedside examination of patients. The aim of this review is to discuss point-of-care bowel ultrasound [POCBUS] in the management of patients with IBD.

Abstract
BACKGROUND In the last years, ultrasound technology has entered clinical practice as a tank and today, it has also allowed no-cardiologists to extend their medical examination without needing to call the consultant and having a good profile of diagnostic accuracy. The ultrasound bedside does not replace the consultant, but it allows not to perform inappropriate consultations with more savings for hospitals. OBJECTIVE The aim was to review the recently published literature to inform the clinician about the most up to date management of use bedside echography in the emergency setting. In this short review, we focused on two types of syndromes, no traumatic- hypotension and dyspnea, common to the three holistic disciplines of medicine, showing the main and basic questions and answers that ultrasound can give us for rapid identification of the problems. METHODS We conducted a systematic review using Pubmed/Medline, Ovid/Willey and Cochrane Library, combining key terms such as "cardiac ultrasound, "cardiac diseases", "emergency medicine", "pocus", "dyspnea", " hypotension". We selected the most relevant clinical trials and review articles (excluding case reports) published in the last 19 years and in our opinion, 59 publications appeared to be the best choice according to the PRISMA statement. In additional papers identified from individual article reference lists were also included. CONCLUSION Recent studies have shown a promise in establishing best practices for evaluation of heart, lung abdomen and deep vessels At the moment, bedside US is widely used in an integrated ultrasound vision just like the holistic view have internal medicine, intensive care and emergency medicine and many medical schools in Europe and the USA are inserting ultrasonography into the core curriculum, but we still have to find a standard method for the training program for minimum competence acquisition.

Abstract
BACKGROUND A linear increase in the number of valvular heart disease is expected due to the aging population, yet most patients with severe valvular heart disease remain undiagnosed. HYPOTHESIS POCUS can serve as a screening tool for valvular heart disease. METHODS We reviewed the literature to assess the strengths and limitations of POCUS in screening and diagnosing valvular heart disease. RESULTS POCUS is an accurate, affordable, accessible, and comprehensive tool. It has a fast learning curve and can prevent unnecessary and more expensive imaging. Challenges include training availability, lack of simplified screening protocols, and reimbursement. Large scale valvular screening data utilizing POCUS is not available. CONCLUSION POCUS can serve as a screening tool and guide the management of patients with valvular heart disease. More data is needed about its efficacy and cost-effectiveness in the screening of patients with valvular heart disease.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2020; 39:2151-2164. [PMID: 32426900 DOI: 10.1002/jum.15324] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Revised: 04/03/2020] [Accepted: 04/15/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVES A rapid, reliable quantitative assessment of left ventricular systolic and diastolic function is important for patient treatment in urgent and dynamic settings. Quantification of annular velocities based on a single 2-dimensional image loop, rather than on Doppler velocities, could be useful in point-of-care or focused cardiac ultrasound. We hypothesized that novel speckle-tracking-based mitral annular velocities would correlate with reference standard tissue Doppler imaging (TDI) velocities in a focused cardiac ultrasound-esque setting. METHODS Two echocardiographers each performed transthoracic echocardiographic measurements before and after induction of anesthesia in supine patients undergoing cardiac surgery. Speckle-tracking echocardiography (STE)-based systolic (S'STE ) and diastolic (E'STE and A'STE ) velocities were compared to TDI and global longitudinal strain/strain rate. We also compared mitral annular displacement by speckle tracking with M-mode imaging. RESULTS Twenty-five patients were included and examined in both preinduction and postinduction states. Speckle-tracking-based velocities correlated with TDI measurements in both states (S', r = 0.73 and 0.76; E', r = 0.87 and 0.65; and A', r = 0.65 and 0.73), showing a mean bias of 25% to 30% of the reference standard measurement. The correlation of S'STE with strain and the strain rate (S-wave) and E'STE with the strain rate (E-wave) was good in awake, spontaneously breathing patients but was less strong in the ventilated state. Similarly, displacement by speckle tracking correlated with M-mode measurements in both states (r = 0.91 and 0.84). Measurements required medians of 31 and 34 seconds; reproducibility was acceptable for S'STE and E'STE . CONCLUSIONS Speckle-tracking-based mitral annular velocities and displacement correlate well with conventional measures as well as with deformation imaging. They may be clinically useful in rapidly assessing both systolic and diastolic function from a single 2-dimensional image loop.

Abstract
Chest pain and heart murmurs are common issues primary care providers must evaluate and manage. Both are a source of anxiety for patients, parents, and providers, necessitating evaluation and understanding to ensure appropriate management. Most pediatric chest pain can be treated symptomatically and with reassurance. This article examines the approach to pediatric chest pain including identification of key historical points, common causes of chest pain, and when to refer. The article also delineates our approach to auscultation, describes common benign murmurs, and offers suggestions on when to refer for further evaluation.

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.

Focused cardiac ultrasound training in medical students: Using an independent, simulator-based curriculum to objectively measure skill acquisition and learning curve. Echocardiography 2020; 37:491-496. [PMID: 32212401 DOI: 10.1111/echo.14641] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 03/01/2020] [Accepted: 03/02/2020] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Using simulators built and validated at the University of Washington (UW), the study sought to test whether medical students can learn the basic skills of focused cardiac ultrasound (FoCUS) from an individually paced, simulator-based curriculum, how skills improve, and the rate at which these skills are acquired. METHODS The curriculum presented didactic material interspersed with hands-on practice. Psychomotor skill was measured by the angle error of the acquired image view plane relative to the correct image view plane. The rate of learning was assessed at baseline, after 7 practice cases, and after 10 cases. To assess the rate of learning, the same case was repeatedly presented at all three tests. To assess students' ability to apply their learning, a previously unseen post-test was included. RESULTS A total of 41 students completed the course. Average angle error improved from 43° ± 24 pretraining to 23° ± 16 post-training, with most students falling within one SD of the view angle acquired by sonographers. Regarding learning curve, or the rate of skill acquisition, an angle error of 43 ± 24° (pre) changed to 22 ± 14° (interim test, P < .0001 vs. pretest) and remained at that level for the post-test evaluation on both the repeated case (23 ± 16°) and the new case (26 ± 18°). CONCLUSIONS This study describes the learning curve and technical skill acquisition in FoCUS. A simulator-based curriculum improved medical student's skills in an objective and quantifiable manner. The individually paced curriculum allowed for independent knowledge and skill attainment, without facilitator oversight.

Abstract
Background Point-of-care ultrasound (POCUS) is emerging as a reliable and valid clinical tool that impacts diagnosis and clinical decision-making as well as timely intervention for optimal patient management. This makes its utility in patients admitted to internal medicine wards attractive. However, there is still an evidence gap in all the medical setting of how its use affects clinical variables such as length of stay, morbidity, and mortality. Methods/design A prospective randomized controlled trial assessing the effect of a surface POCUS of the heart, lungs, and femoral and popliteal veins performed by an internal medicine physician during the first 24 h of patient admission to the unit with a presumptive cardiopulmonary diagnosis. The University of Melbourne iHeartScan, iLungScan, and two-point venous compression protocols are followed to identify left and right ventricular function, significant valvular heart disease, pericardial and pleural effusion, consolidation, pulmonary edema, pneumothorax, and proximal deep venous thrombosis. Patient management is not commanded by the protocol and is at the discretion of the treating team. A total of 250 patients will be recruited at one tertiary hospital. Participants are randomized to receive POCUS or no POCUS. The primary outcome measured will be hospital length of stay. Secondary outcomes include the change in diagnosis and management, 30-day hospital readmission, and healthcare costs. Discussion This study will evaluate the clinical impact of multi-organ POCUS in internal medicine patients admitted with cardiopulmonary diagnosis on the hospital length of stay. Recruitment of participants commenced in September 2018 and is estimated to be completed by March 2020. Trial registration Australian and New Zealand Clinical Trial Registry, ACTRN12618001442291.

Abstract
BACKGROUND Intestinal ultrasound (IUS) examination is a first-line non-invasive imaging procedure for patients with suspicion of bowel diseases. AIM To assess the feasibility, reproducibility and diagnostic accuracy of a pocket-size ultrasound device (PUD) in identifying the presence of intestinal alterations in patients consecutively recruited to undergo IUS examination. METHODS 200 consecutive patients (57% female, 48.8 years) underwent both PUD (two independent investigators) and IUS examination on the same day. Nine ultrasonographic signs were systematically searched for. PUD inter-observer reproducibility was assessed by kappa statistic and ICC. The diagnostic accuracy of PUD as compared to IUS results was assessed by calculating sensitivity, specificity and corresponding positive and negative likelihood ratios. RESULTS PUD and IUS examinations were successful in 100% of the patients. PUD reproducibility was good/excellent at evidencing the presence (ICC 0.84) and length (ICC 0.85) of an intestinal tract with thickened wall and abdominal free fluid (ICC 0.87). The diagnostic accuracy of PUD, compared to traditional IUS, was good with regard to the presence of bowel wall thickening (sensitivity 92%, specificity 95%), the length of the thickened bowel (sensitivity 94%, specificity 95%) and the presence of free fluid (sensitivity 81%, specificity 99%). CONCLUSIONS PUD is a feasible, reproducible and accurate first-line screening tool for the assessment of the gastro-intestinal tract.

The goal of this study was to compare left ventricular fractional shortening (FS) and left ventricular ejection fraction (LVEF) obtained by a newer handheld echo (HHE) machine to standard transthoracic echocardiogram (TTE) in children. METHODS Pediatric outpatients (Birth-18 years) undergoing TTE were prospectively enrolled. HHE protocol included 2D and M-mode images from the parasternal long, short, and apical-4 chamber views. HHE and TTE measurements were reviewed for agreement. Kappa statistic was used to analyze qualitative indices while FS and LVEF were analyzed with Lin's concordance correlation coefficient (CCC) and Bland-Altman limits of agreement (loa). RESULTS Sixty children were enrolled; 55 were included in the quantitative analysis. Mean age was 7.5 ± 5.5 years; 67% males; median HHE image acquisition duration was 2.3(1-5) minutes. Fractional shortening and EF by HHE showed good agreement with TTE [CCC = 0.82, 95%CI (0.73,0.90), mean bias -3.18%, loa (-7.00,6.44%) vs CCC = 0.81 (0.72,0.90), mean bias -0.87%, loa (-6.94,5.17%], respectively. In children ≤5 years, HHE FS (n = 20) and EF (n = 21) agreed with TTE measurement [0.59 (0.31, 0.88), mean bias 0.30%, loa (-8.5, 9.1%); 0.79 (0.63, 0.96), mean bias 0.10%, loa (-5.99, 6.14)]. Kappa values for RV size, function, and LV function were 1.00 (P < .05); 0.75 for LV size (P < .05) and 0.66 for pericardial effusion (P < .05). CONCLUSION Handheld echo demonstrates good correlation with standard TTE for focused assessment of ventricular chamber sizes and function in children.

Abstract
OBJECTIVE This prospective observational study evaluates the utility of expert focused cardiac ultrasound (eFCU) with spectral Doppler to inform decision making in established patients with specific, selected congenital cardiac defects in outreach clinics. Secondary objectives include determining if the addition of eFCU expands capacity in paediatric cardiology outreach clinics and if it improves the patient experience. METHODS Patients aged 2 months to 19 years old with a diagnosis of ventricular septal defect, atrial septal defect, atrioventricular septal defect, patent ductus arteriosus, aortic valve stenosis, or pulmonary valve stenosis with the need for follow-up echocardiography in an outreach clinic from August 2017 to June 2018 were studied. A novel assessment tool was used to determine the success of eFCU. RESULTS Forty-two patients from 11 clinics underwent eFCU with one unsuccessful exam making the failure rate 2.3% (95% CI 0.0006-0.1256). Addition of eFCU led to a significant increase in volume of patients able to be seen 19 versus 15.5 (p < 0.01). A majority of parents/patients reported a positive experience with eFCU. CONCLUSION Expert focused cardiac ultrasound with spectral Doppler can be used successfully for follow-up in patients with select CHD and the addition of eFCU permits increased patient capacity in outreach clinics and has the potential to improve the patient experience.

Abstract
BACKGROUND Incorporating focused cardiac ultrasonography (FoCUS) into clinical examination could improve the diagnostic yield of bedside patient evaluation. PURPOSE To compare the accuracy of FoCUS-assisted clinical assessment versus clinical assessment alone for diagnosing left ventricular dysfunction or valvular disease in adults having cardiovascular evaluation. DATA SOURCES English-language searches of MEDLINE, Embase, and Web of Science from 1 January 1990 to 23 May 2019 and review of reference citations. STUDY SELECTION Eligible studies were done in patients having cardiovascular evaluation; compared FoCUS-assisted clinical assessment versus clinical assessment alone for the diagnosis of left ventricular systolic dysfunction, aortic or mitral valve disease, or pericardial effusion; and used transthoracic echocardiography as the reference standard. DATA EXTRACTION Three study investigators independently abstracted data and assessed study quality. DATA SYNTHESIS Nine studies were included in the meta-analysis. The sensitivity of clinical assessment for diagnosing left ventricular dysfunction (left ventricular ejection fraction <50%) was 43% (95% CI, 33% to 54%), whereas that of FoCUS-assisted examination was 84% (CI, 74% to 91%). The specificity of clinical assessment was 81% (CI, 65% to 90%), and that of FoCUS-assisted examination was 89% (CI, 85% to 91%). The sensitivities of clinical assessment and FoCUS-assisted examination for diagnosing aortic or mitral valve disease (of at least moderate severity) were 46% (CI, 35% to 58%) and 71% (CI, 63% to 79%), respectively. Both the clinical assessment and the FoCUS-assisted examination had a specificity of 94% (CI, 91% to 96%). LIMITATION Evidence was scant, persons doing ultrasonography had variable skill levels, and most studies had unclear or high risk of bias. CONCLUSION Clinical examination assisted by FoCUS has greater sensitivity, but not greater specificity, than clinical assessment alone for identifying left ventricular dysfunction and aortic or mitral valve disease; FoCUS-assisted examination may help rule out cardiovascular pathology in some patients, but it may not be sufficient for definitive confirmation of cardiovascular disease suspected on physical examination. PRIMARY FUNDING SOURCE None. (PROSPERO: CRD42019124318).

Abstract
Recent technological advances in echocardiography, with progressive miniaturization of ultrasound machines, have led to the development of handheld ultrasound devices (HUD). These devices, no larger than some mobile phones, can be used to perform partial, focused exams as an extension to the physical examination. The European Association of Cardiovascular Imaging (EACVI) acknowledges that the dissemination of appropriate HUD use is inevitable and desirable, because of its potential impact on patient management. However, as a scientific society of cardiac imaging, our role is to provide guidance in order to optimize patient benefit and minimize drawbacks from inappropriate use of this technology. This document provides updated recommendations for the use of HUD, including nomenclature, appropriateness, indications, operators, clinical environments, data management and storage, educational needs, and training of potential users. It also addresses gaps in evidence, controversial issues, and future technological developments.

Abstract
The aim of this study was to review the scientific literature available on the comparison of hand-held ultrasound devices with high-end systems for abdominal and pleural applications. PubMed, Embase, Web of Science and Cochrane were searched following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Original research describing hand-held ultrasound devices compared with high-end systems was included and assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2. The search was limited to articles published since 1 January 2012. A total of 2486 articles were found and screened by title and abstract. A total of 16 articles were chosen for final review. All of the included articles showed good overall agreement between hand-held and high-end ultrasound systems. Strong correlations were found when evaluating ascites, hydronephrosis, pleural cavities, in detection of abdominal aortic aneurysms and for use with obstetric and gynaecological patients. Other articles found good agreement for cholelithiasis and for determining the best site for paracentesis. QUADAS-2 analysis suggested few risks of bias and almost no concerns regarding applicability. For distinct clinical questions, hand-held devices may be a valuable supplement to physical examination. However, evidence is inadequate, and more research is needed on the abdominal and pleural use of hand-held ultrasound with more standardised comparisons, using only blinded reviewers.

Abstract
BACKGROUND When performed by cardiologists, hand-held echocardiography (HHE) can assess ventricular systolic function and valve disease in adults, but its accuracy and utility in congenital heart disease is unknown. In hypoplastic left heart syndrome (HLHS), the echocardiographic detection of depressed right ventricular (RV) systolic function and higher grade tricuspid regurgitation (TR) can identify patients who are at increased risk of morbidity and mortality and who may benefit from additional imaging or medical therapies. METHODS Children with HLHS after Stage I or II surgical palliation (Norwood or Glenn procedures) were prospectively enrolled. Subjects underwent HHE by a pediatric cardiologist on the same day as standard echocardiography (SE). Using 4-point scales, bedside HHE assessment of RV systolic function and TR were compared with blinded assessment of offline SE images. Concordance correlation coefficient (CCC) was used to evaluate agreement. RESULTS Thirty-two HHEs were performed on 15 subjects (Stage I: n = 17 and Stage II: n = 15). Median subject age was 3.4 months (14 days-4.2 years). Median weight was 5.9 kg (2.6-15.4 kg). Bedside HHE assessment of RV systolic function and TR severity had substantial agreement with SE (CCC = 0.80, CCC = 0.74, respectively; P < .001). HHE sensitivity and specificity for any grade of depressed RV systolic function were 100% and 92%, respectively, and were 94% and 88% for moderate or greater TR, respectively. Average HHE scan time was 238 seconds. CONCLUSIONS HHE offers a rapid, bedside tool for pediatric cardiologists to detect RV systolic dysfunction and hemodynamically significant TR in HLHS.

Abstract
Echocardiography (Echo) has a myriad of clinical applications. Traditionally, it was performed and interpreted by cardiologist but the scope of its applications has lead physicians of other specialities to learn this useful skill. One of the newer and expanding scope of echocardiography is point-of-care (POC) echocardiography. In this review article, we aim to discuss the clinical applications of POC echo, common protocols and its limitations. Despite its widespread use, there is paucity of data describing its clinical efficacy and there is lack of guidelines regarding credentialing and quality control of POC echo.

Abstract
In recent years, advances in technology have enabled hand-held echocardiography (HHE) to generate high-quality 2-dimensional and color Doppler images. As these devices become smaller, simpler, and more affordable, the question of whether HHE can augment or replace auscultation as the primary mode of cardiovascular diagnosis has become increasingly more relevant. If widely implemented, HHE has the potential for significant cost savings and better resource utilization. This review examines studies comparing the sensitivities of auscultation, HHE, and standard echocardiography in detecting various valvular lesions and discusses why current evidence supports the use of HHE to augment the physical examination, which can lead to more reliable and rapid bedside diagnoses, triage, and appropriate treatment of structural cardiac abnormalities.

Abstract
INTRODUCTION Point of care ultrasound (POCUS) is routinely used by intensivists and emergency physicians for many years. Its interest is not arguable any more for these specialists, despite the large variety of diseases they care. Hospitalists and internists also should find some interest in POCUS, which convenience and wide range of indications responds well to the variety of their practice. However, it is still not widely used in internal medicine departments. METHODS We here report our experience of using a pocket-sized ultrasound device in a French internal medicine department. The device used was a Vscan Dual Probe, GE, whose two probes and presets allow for cardiac, abdominal, pulmonary, obstetric, vascular, pulmonary, and superficial soft tissue exploration. One physician of the ward received a course for POCUS that was initially dedicated for emergency physicians. This study reports on the results of the examinations made between January and September 2015. For each examination performed, clinical usefulness was assessed at the time of patient discharge, by two independent physicians who reviewed the clinical course and the results of conventional imaging and rated their evaluation on a Likert scale. RESULTS One hundred and four examinations were evaluated. The mean duration of the ultrasound examination was 9±5minutes. The POCUS conclusions were corrected by disease course or the results of conventional imaging in 10 (9.6%) cases. The presets of the device: heart, soft tissue, lung, abdomen and vascular were used respectively in 32, 30, 21, 12 and 5% of the examinations. The main indications of POCUS examination were for identification of pleural, pericardial or peritoneal effusion, and to assess the central venous pressure by inferior vena cava examination. Eighteen examinations were performed for puncture of effusion. The retrospectively evaluated clinical benefit was clearly demonstrated in 78% of cases. The agreement between the two blinded assessors was good (kappa coefficient at 0.82). CONCLUSION Pocket-sized ultrasound device could be used in internal medicine wards. However, its limited performance compared to more sophisticated echography limits the possible explorations and their reliability, which encourages caution and makes critical the question of the initial training of doctors and medical students.

Heart failure (HF) continues to grow as a cause of morbidity and mortality in our community and presents a significant public health problem, predominantly in individuals ≥65 years of age. Early intervention in asymptomatic HF subjects (Stage A/B) at risk of progression to symptomatic HF (Stage C/D) may provide an opportunity to halt this epidemic. The ability of cardiac imaging to assess cardiac structure and function permits early identification of those at increased risk of developing symptomatic HF. Systolic, diastolic, and structural left ventricular parameters each predict symptomatic HF, but no single parameter has sufficient sensitivity for screening to identify individuals with Stage A/B HF who are at increased risk of disease progression. Transthoracic echocardiography (TTE) has the advantage over other imaging modalities in being able to measure systolic, diastolic, and structural left ventricular parameters, and it identified at least 1 abnormal parameter in >50% of individuals with Stage A/B HF ≥65 years of age. Moreover, identification of at least 1 abnormality according to TTE in individuals with Stage A/B HF ≥65 years of age had 72% to 82% sensitivity for detection of those who subsequently developed symptomatic HF. Therefore, a case can be made for cardiac imaging by using TTE for community-dwelling populations with Stage A/B HF ≥65 years of age to identify those with increased risk of symptomatic HF who can be offered preventative therapies. Further studies are required to determine the best strategy for identifying the risk of symptomatic HF in younger individuals.

Abstract
Background: Handheld echocardiography (HHE) has been increasingly used for rheumatic heart disease screening and in adult emergency room settings. Aims: This study aimed to validate the accuracy of HHE in the diagnosis of congenital heart disease (CHD). Settings and Design Methodology: This is a prospective study carried out at three pediatric cardiology outpatient clinics in Khartoum, Sudan. All patients with suspected CHD were evaluated by clinical examination followed by HHE, performed using a modified segmental approach. Then, a complete study was performed using a standard echocardiography machine. The results were then compared using appropriate statistical tools. Results: A total of eighty cases were included with the following diagnoses either in isolation or combination: ventricular septal defect (n = 23), atrial septal defect (n = 10), pulmonary stenosis (n = 7), tetralogy of Fallot (n = 7), patent ductus arteriosus (n = 6), atrioventricular septal defect (n = 6), transposition of the great arteries (n = 6), and other diagnoses (n = 15). Agreement between HHE and SE was excellent both for visualizing heart segments (κ =77%–100% with a mean of 92.9%) and for diagnosis of CHD (κ =66%–100% with a mean of 91.7%). The sensitivity of HHE was 69.2%–100% (mean = 90.2%) and specificity was 98.5%–100% (mean = 99.3%). Conclusion: This study supports extending the utility of HHE in children for screening of CHD in addition to its current role in rheumatic heart disease screening.

Abstract
Competent cardiac auscultation remains a most important skill for the detection of heart disease. Currently it is poorly taught and often ignored or poorly performed, resulting in inaccurate and inefficient patient assessments. This review documents that teaching can be over 90% effective with new, proven teaching methods emphasizing repetition and normal-abnormal comparisons of sounds, using computer-aided and online resources. At present, these concepts are not widely adopted by medical schools. Our current knowledge of teaching heart auscultation is critically reviewed, including traditional bedside, clinic and classroom settings, as well as computer, simulator, and multimedia-based learning. The assessment of auscultation skill in the learning process. The adoption of competence-based learning promises to integrate the assessment of auscultation skill in the learning process. Newer teaching methods, such as auditory training and repetitive listening, offer excellent murmur recognition and diagnosis learning, and hand-held ultrasound is proposed as a helpful adjunct to teaching auscultation. Although ongoing research remains important to develop better teaching methods, the adoption of proven existing concepts has great potential to improve teaching and practice of this valuable skill.

Abstract
BACKGROUND Handheld echocardiography (HHE) is concordant with standard transthoracic echocardiography (TTE) in a variety of settings but has not been thoroughly compared to traditional TTE in patients with acute myocardial infarction (AMI). HYPOTHESIS Completed by experienced operators, HHE provides accurate diagnostic capabilities compared with standard TTE in AMI patients. METHODS This study prospectively enrolled patients admitted to the coronary care unit with AMI. Experienced sonographers performed HHE with a V-scan. All patients underwent clinical TTE. Each HHE was interpreted by 2 experts blinded to standard TTE. Agreement was assessed with κ statistics and concordance correlation coefficients. RESULTS Analysis included 82 patients (mean age, 66 years; 74% male). On standard TTE, mean left ventricular (LV) ejection fraction was 46%. Correlation coefficients between HHE and TTE were 0.75 (95% confidence interval: 0.66 to 0.82) for LV ejection fraction and 0.69 (95% confidence interval: 0.58 to 0.77) for wall motion score index. The κ statistics ranged from 0.47 to 0.56 for LV enlargement, 0.55 to 0.79 for mitral regurgitation, and 0.44 to 0.57 for inferior vena cava dilatation. The κ statistics were highest for the anterior (0.81) and septal (0.71) apex and lowest for the mid inferolateral (0.36) and basal inferoseptal (0.36) walls. CONCLUSIONS In patients with AMI, HHE and standard TTE demonstrate good correlation for LV function and wall motion. Agreement was less robust for structural abnormalities and specific wall segments. In experienced hands, HHE can provide a focused assessment of LV function in patients hospitalized with AMI; however, HHE should not substitute for comprehensive TTE.

Abstract
The development of hand-carried, battery-powered ultrasound devices has created a new practice in ultrasound diagnostic imaging, called 'point-of-care' ultrasound (POCUS). Capitalising on device portability, POCUS is marked by brief and limited ultrasound imaging performed by the physician at the bedside to increase diagnostic accuracy and expediency. The natural evolution of POCUS techniques in general medicine, particularly with pocket-sized devices, may be in the development of a basic ultrasound examination similar to the use of the binaural stethoscope. This paper will specifically review how POCUS improves the limited sensitivity of the current practice of traditional cardiac physical examination by both cardiologists and non-cardiologists. Signs of left ventricular systolic dysfunction, left atrial enlargement, lung congestion and elevated central venous pressures are often missed by physical techniques but can be easily detected by POCUS and have prognostic and treatment implications. Creating a general set of repetitive imaging skills for these entities for application on all patients during routine examination will standardise and reduce heterogeneity in cardiac bedside ultrasound applications, simplify teaching curricula, enhance learning and recollection, and unify competency thresholds and practice. The addition of POCUS to standard physical examination techniques in cardiovascular medicine will result in an ultrasound-augmented cardiac physical examination that reaffirms the value of bedside diagnosis.

Abstract
Background Ultrasound exam as a screening test for abdominal aorta (AA) can visualize the aorta in 99% of patients and has a sensitivity and specificity approaching 100% in screening settings for aortic aneurysm. Pocket Size Imaging Device (PSID) has a potential value as a screening tool, because of its possible use in several clinical settings. Our aim was to assess the impact of demographics and cardiovascular (CV) risk factors on AA size by using PSID in an outpatient screening. Methods Consecutive patients, referring for a CV assessment in a 6 months period, were screened. AA was visualized by subcostal view in longitudinal and transverse plans in order to determine the greatest anterior-posterior diameter. After excluding 5 patients with AA aneurysm, 508 outpatients were enrolled. All patients underwent a sequential assessment including clinical history with collection of CV risk factors, physical examination, PSID exam and standard Doppler echoc exam using a 2.5 transducer with harmonic capability, both by expert ultrasound operators, during the same morning. Standard echocardiography operators were blinded on PSID exam and viceversa. Results Diagnostic accuracy of AA size by PSID was tested successfully with standard echo machine in a subgroup (n = 102) (rho = 0.966, p < 0.0001). AA diameter was larger in men than in women and in ≥50 -years old subjects than in those <50 -years old (both p < 0.0001). AA was larger in patients with coronary artery disease (CAD) (p < 0.0001). By a multivariate model, male sex (p < 0.0001), age and body mass index (both p < 0.0001), CAD (p < 0.01) and heart rate (p = 0.018) were independent predictors of AA size (cumulative R2 = 0.184, p < 0.0001). Conclusion PSID is a reliable tool for the screening of determinants of AA size. AA diameter is greater in men and strongly influenced by aging and overweight. CAD may be also associated to increased AA diameter.

Abstract
Over the last decade, the use of portable ultrasound scanners has enhanced the concept of point of care ultrasound (PoC-US), namely, "ultrasound performed at the bedside and interpreted directly by the treating clinician." PoC-US is not a replacement for comprehensive ultrasound, but rather allows physicians immediate access to clinical imaging for rapid and direct solutions. PoC-US has already revolutionized everyday clinical practice, and it is believed that it will dramatically change how ultrasound is applied in daily practice. However, its use and teaching are different from continent to continent and from country to country. This World Federation for Ultrasound in Medicine and Biology position paper discusses the current status and future perspectives of PoC-US. Particular attention is given to the different uses of PoC-US and its clinical significance, including within emergency and critical care medicine, cardiology, anesthesiology, rheumatology, obstetrics, neonatology, gynecology, gastroenterology and many other applications. In the future, PoC-US will be more diverse than ever and be included in medical student training.

Abstract
Point-of-care ultrasonography (POCUS) is a safe and rapidly evolving diagnostic modality that is now utilized by health care professionals from nearly all specialties. Technological advances have improved the portability of equipment, enabling ultrasound imaging to be executed at the bedside and thereby allowing internists to make timely diagnoses and perform ultrasound-guided procedures. We reviewed the literature on the POCUS applications most relevant to the practice of internal medicine. The use of POCUS can immediately narrow differential diagnoses by building on the clinical information revealed by the traditional physical examination and refining clinical decision making for further management. We describe 2 common patient scenarios (heart failure and sepsis) to highlight the impact of POCUS performed by internists on efficiency, diagnostic accuracy, resource utilization, and radiation exposure. Using POCUS to guide procedures has been found to reduce procedure-related complications, along with costs and lengths of stay associated with these complications. Despite several undisputed advantages of POCUS, barriers to implementation must be considered. Most importantly, the utility of POCUS depends on the experience and skills of the operator, which are affected by the availability of training and the cost of ultrasound devices. Additional system barriers include availability of templates for documentation, electronic storage for image archiving, and policies and procedures for quality assurance and billing. Integration of POCUS into the practice of internal medicine is an inevitable change that will empower internists to improve the care of their patients at the bedside.

Abstract
Complementing the physical examination with a point-of-care ultrasound study (POCUS) can improve patient triage. We aimed to study the impact of POCUS on the diagnosis and management of outpatients and hospitalized patients with suspected cardiac disease. In this multicenter study, a pocket-sized device was used to perform POCUS when the diagnosis or patient management was unclear based on anamnesis, physical examination, and basic diagnostic testing. Eighteen physicians (cardiac fellows 49%, cardiologists 30%, and echocardiographers 21%) performed physical examinations extended by POCUS on 207 patients (inpatients 83% and outpatients 17%). POCUS findings resulted in a change in the primary diagnosis in 14% of patients. In patients whose diagnosis remained unchanged, POCUS results reinforced the initial diagnosis in 48% of the cases. In 39% of the patients, the diagnostic plan was altered, including referral (16%) or deferral (23%) to other diagnostic techniques. Alteration in medical treatment (drug discontinuation or initiation) occurred in 11% of the patients, and in 7% POCUS results influenced the decision whether to perform a therapeutic procedure. Hospitalization or discharge was determined after POCUS in 11% of the patients. In conclusion, during patient triage, extension of the physical examination by POCUS can cause physicians to alter their initial diagnosis, resulting in an immediate change of diagnostic and therapeutic procedures. Based on POCUS results, physicians altered the diagnostic plan either by avoiding or referring patients to other diagnostic procedures in almost half of the studied population.

Abstract
BACKGROUND: The ultraportable echocardiogram machine, with relevant portability and easiness in performing diagnoses, when in experienced hands, may contribute to the reliability of preoperative evaluation in noncardiac surgeries. OBJECTIVES: To assess cardiac function parameters in patients aged older than 60 years, candidates of elective noncardiac surgeries, classified as ASA1 or ASA 2 according to surgical risk. METHODS: A total of 211 patients referred for elective surgeries, without suspicion of previous heart diseases, were included in the study. Assessment of patients was conducted by conventional echocardiogram using the ultraportable V Scan (GE) device right after the pre-anesthetic clinical evaluation. We assessed the clinical impact of echocardiography results by using a questionnaire addressed to the anesthetist. RESULTS: Mean age of patients was 68.9 ± 7.0 years, 154 were women. The most frequent surgeries were: a) facectomy - cataract - 18; b) inguinal hernia surgery - 18; c) Cholecystectomy - 16. We found 58 normal tests (27.5%), 70 (33.2%) with mild valve reflux, and 83 (39.3%) with relevant abnormality, such as increase in heart chamber size, global and/or segmental contractile dysfunction, significant valve dysfunction or other unspecified. Test results caused delay of surgical procedure for a more detailed cardiac evaluation in 20 (9.5%) patients, and change in anesthetic management in 7 (3.3%). CONCLUSION: There was a considerable clinical impact with the use of the ultraportable echocardiography, since one out of every ten patients evaluated had their clinical management changed due to the detection of previously unsuspected, significant heart diseases, with the potential for severe complications.

MÉTODOS: Foram incluídos 211 pacientes direcionados para cirurgias eletivas diversas e sem suspeita prévia de cardiopatia. Os pacientes foram avaliados por técnica ecocardiográfica convencional, usando o aparelho ultraportátil V Scan (GE) logo após a avaliação clínica pré-anestésica. Avaliamos o impacto clínico dos resultados da ecocardiografia por um questionário dirigido ao anestesista. RESULTADOS: A idade média dos pacientes foi 68,9 ± 7,0 anos, 154 do sexo feminino. As cirurgias mais frequentes foram: a) Facectomia-catarata - 18; b) Herniorrafia inguinal - 18; c) Colecistectomia - 16. No total, foram observados 58 exames normais (27,5%), 70 (33,2%) exames que apresentavam leves refluxos valvares e 83 (39,3%) exames com alguma anormalidade relevante, como aumento de câmara cardíaca, disfunção contrátil global e/ou segmentar, disfunção valvar mais significativa ou outra não especificada. Os resultados determinaram que 20 (9,5%) pacientes tivessem seus procedimentos cirúrgicos adiados até avaliação cardiológica mais detalhada e em 7 (3,3%) houve mudança na conduta anestésica. CONCLUSÃO: Houve um impacto clínico considerável com o uso da ecocardiografia ultraportátil, pois um em cada dez pacientes avaliados sofreu modificação na conduta clínica, em função da detecção de cardiopatias significativas, não suspeitadas previamente, e com potencial para complicações graves.

Abstract
The introduction of portable, pocket-sized echocardiography devices in various healthcare systems has raised new questions with regards to their realistic use in clinical practice. Several studies have already attempted to provide information regarding their safety and diagnostic potential, the training required to operate them, as well as their direct comparison with standard echocardiography machines. This manuscript is a review of the literature of the documents or position papers which employ the use of pocket or handheld devices. Following review of the literature, we suggest that these miniaturized devices can provide a valuable diagnostic tool that can complement and improve the diagnostic yield of clinical examination. When operated by appropriately trained professionals, they can provide a limited but very reliable echocardiographic assessment. Pocket-sized echocardiography is a part of physical examination and should not be considered a complete echocardiographic scan. Optimal training is required for the smooth operation of handheld echocardiography.
