The rationale for change is discussed, in addition to how the reference intervals were defined and the current limitations to their use. The importance of interpretation of echocardiographic parameters within the clinical context is explored, as is grading of abnormality. Each of the following echo parameters are discussed and updated in turn: left ventricular linear dimensions and LV mass; left ventricular volumes; left ventricular ejection fraction; left atrial size; right heart parameters; aortic dimensions; and tissue Doppler imaging. There are several important conceptual changes to the assessment of the heart’s structure and function within this guideline. New terminology for left ventricular function and left atrial size are introduced. The British Society of Echocardiography has advocated a new approach to the assessment of the aortic root, the right heart, and clarified the optimal methodology for assessment of LA size. The British Society of Echocardiography has emphasized a preference to use, where feasible, indexed measures over absolute values for any chamber size.</p>","PeriodicalId":45749,"journal":{"name":"Echo Research and Practice","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2020-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/cb/bd/ERP-19-0050.PMC7040881.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37683230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She had a history of bicuspid aortic valve endocarditis with aortic root abscess repaired with bioprosthetic aortic valve replacement and pericardial patch reconstruction of the left ventricular outflow tract and non-coronary sinus 6 weeks previously. Echocardiographic and cardiac CT imaging confirmed three foci of breakdown of the pericardial patch repair with active bleeding into a large posterior pseudoaneurysm (92 mm diameter) compressing the left atrium and pulmonary artery. Following multidisciplinary discussion, the consensus was to attempt urgent percutaneous closure of the defect, given the prohibitive surgical risks. The procedure was performed under fluoroscopic and 3D-transoesophageal guidance. TOE demonstrated the pericardial patch breaches and active bleeding into the large pseudoaneurysm (Figs 1 and 2). Initial deployment of an Amplatzer atrial septal defect occluder resulted in significant flow reduction, but there remained two small peri-device leaks (Fig. 3). During an attempt to implant an additional smaller Amplatzer vascular plug (AVP-2) to rectify this, the initial device dislodged and embolised into the pseudoaneurysm. This was felt irretrievable and unlikely to be clinically significant given its containment. The embolised device freely floated within the pseudoaneurysm, uniquely akin to a satellite orbiting in space (Video 1). The secondary device was removed and initial breach was satisfactorily closed with a 15-mm-sized Amplatzer atrial septal defect occluder (third device). This was confirmed to be wellseated on real-time 3D imaging (Video 2), with negligible residual leak on TOE (Fig. 4). This is the first published case of percutaneous cardiac device embolization into a pseudoaneurysm cavity that we are aware of.

This is an updated version which recognises that, not only should all echocardiographers be individually accredited as competent to practice, but that departments also need to be well organised and have the facilities, equipment and processes to ensure the services they deliver are of an appropriate clinical standard. In combination with individual accreditation, departmental accreditation lays down standards to help ensure safe and effective patient care. These standards supersede the 2012 BSE Departmental Accreditation Standards. Standards are set to cover all potential areas of practice, including transthoracic (level 2) echocardiography, transoesophageal echocardiography, stress echocardiography, training, and emergency (level 1) echocardiography.

Thirteen anesthesia interns took a pre-test and then had 3 weeks to complete the training modules on their own time before taking a post-test. The average score on the post-test (74.6% ± 11.08%) was higher than the average score on the pre-test (57.7% ± 9.27%) (<i>P</i> < 0.001). Scores did not differ between extreme function (severe dysfunction or hyperdynamic function) and non-extreme function (normal function or mild or moderate dysfunction) questions on both the pre-test (<i>P</i> = 0.278) and post-test (<i>P</i> = 0.093).

Quantification of right heart parameters is important in a variety of clinical scenarios including diagnosis, prognostication, and monitoring response to therapy. Although echocardiography remains the first-line imaging investigation for right heart assessment, published guidance is relatively sparse in comparison to that for the left ventricle. This guideline document from the British Society of Echocardiography describes the principles and practical aspects of right heart assessment by echocardiography, including quantification of chamber dimensions and function, as well as assessment of valvular function. While cut-off values for normality are included, a disease-oriented approach is advocated due to the considerable heterogeneity of structural and functional changes seen across the spectrum of diseases affecting the right heart. The complex anatomy of the right ventricle requires special considerations and echocardiographic techniques, which are set out in this document. The clinical relevance of right ventricular diastolic function is introduced, with practical guidance for its assessment. Finally, the relatively novel techniques of three-dimensional right ventricular echocardiography and right ventricular speckle tracking imaging are described. Despite these techniques holding considerable promise, issues relating to reproducibility and inter-vendor variation have limited their clinical utility to date.","PeriodicalId":45749,"journal":{"name":"Echo Research and Practice","volume":null,"pages":null},"PeriodicalIF":6.3,"publicationDate":"2020-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48699696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
