Analysis for echocardiography
更新日志
Several new calculations and analyses:
• Left ventricular wall motion score index added to “Left Ventricle” category, along with semi-quantitative calculation of the left ventricular ejection fraction. Toggle switch shows typical coronary artery perfusion for each left ventricular wall segment.
• Biventricular coupling index added to “Pulmonary Artery” category for helping to distinguish precapillary from postcapillary pulmonary hypertension.
• Left atrial appendage emptying velocity added to “Atria” category for prediction of atrial fibrillation after cryptogenic stroke.
Additional new features:
• Demographics and Clinical Conditions view modified to include a toggle switch for atrial fibrillation, enhancing assessment by the Analytic Engine when this rhythm is present. Consider making this view one of your favorites for easy access, since once the patient’s sex is designated here, it no longer is necessary to specify the sex when utilizing the Analytic Engine.
• Right atrial pressure view modified to permit 3 different ways to enter mean right atrial pressure.
• Many refinements of the Analytic Engine.
• Updated list of echocardiography and cardiology organizations. expanded to 79 direct links, found under “Organizations” using the “?” button at the top right of the opening app screen.
EchoLab is optimized for Dark Mode, ideal for use in the dimmed lighting of a typical echocardiography reading room.
Remember that designating Quick Entry views as favorites permits easy access to the most frequently used echocardiographic measurements under the Favorites tab.

应用描述
EchoLab presents the formulas and algorithms used in an adult echocardiography laboratory. Designed by a practicing cardiologist, EchoLab provides a comprehensive framework for teaching the principles of quantitative echocardiography, or cardiac ultrasound. EchoLab's unique design permits sharing of entered and calculated data between its many formulas. Quick Entry views provide immediate access to a wide array of echocardiographic calculations.
Unique to EchoLab among echocardiography applications is the powerful Analytic Engine, which synthesizes results from multiple calculations into a cohesive overview with a comprehensive summary, with integration of ASE/EACVI guidelines. The included companion app for the Apple Watch provides a ready reference when performing or interpreting echocardiograms.
Available with each calculation is a graphical display of the corresponding mathematical equation, along with tips for using the calculation and medical literature references with integrated hyperlinks.

• New Constrictive Pericarditis versus Restrictive Cardiomyopathy view integrates this portion of the 2016 ASE/EACVI diastology guidelines into the Analytic Engine. An Ancillary Findings button appears for entry of additional data if restrictive physiology is possible.
• Deprecated 2009 ASE diastology assessment removed as an option from the Analytic Engine, which now exclusively uses the 2016 ASE/EACVI diastology guidelines in the Quick Entry (diastology) view.
• Quick Entry (diastology) view now includes:
• Entry of mitral inflow L-wave velocity, which, if abnormal, suggests a pseudonormal diastolic filling pattern.
• Toggle switch to signify the presence of left bundle branch block or ventricular pacing, which, if present, may affect the diastolic assessment.
• Button for direct access to the new Constrictive Pericarditis versus Restrictive Cardiomyopathy view.

• New Exercise Stress Echocardiography (ESE) view permits calculation and analysis from echocardiographic measurements obtained at peak exercise for assessment of non-ischemic heart disease.
You can open the ESE view directly from the new Stress Echocardiography category, or with the “Exercise stress” button in the following views:
• Cardiac Output (Teichholz)
• Mitral ERO Area (PISA)
• Quick Entry (aortic regurgitation)
• Quick Entry (aortic stenosis)
• Quick Entry (left heart)
• Quick Entry (mitral regurgitation)
• Quick Entry (mitral stenosis)
• Quick Entry (pulmonary hypertension)
• Quick Entry (right heart)
• Quick Entry (standard)
The ESE view has numerous possible data entries in the top half and calculation results in the bottom half. As a helpful guide, relevant fields are highlighted if the ESE view is opened using the “Exercise stress” button in one of the views above. For example, if you first go to Quick Entry (mitral regurgitation) and then use the “Exercise stress” button to open the ESE view, then all of the input and output fields in the ESE view relevant to the evaluation of mitral regurgitation at peak exercise are highlighted. Relevant input fields have a thick white or green border (depending on whether there is active data), and relevant output fields have a yellow border.
As in all views in EchoLab, the “Analyze” button at the bottom left generates an analysis that integrates data from all views, including the ESE view.
• New Diastolic Stress Echocardiography view added to the Left Ventricle and Stress Echocardiography categories, with peak-exercise diastolic Doppler measurements provided for the Analytic Engine.
• echocardiographic Pulmonary to Left Atrial Ratio (ePLAR) view in the Pulmonary Artery category enhanced with a clarified assessment statement and with a link to the pulmonary artery mean pressure calculation.
• Aortic transvalvular flow rate added to the set of calculations in Aortic Valve Area (VTI) and to the Analytic Engine as an additional parameter for evaluation of aortic stenosis.
• Left Atrial Volume calculation and Quick Entry views with left atrial measurement entry updated to allow a choice of area-length, disk summation, and 3D methods to use in the Analytic Engine.
• Separate “Left Ventricular Diastology” section added to output from the Analytic Engine.
• Quick Entry (basic) view re-named as Quick Entry (standard), containing all of the measurements in a standard transthoracic echocardiogram.
• Bundled EchoLab app for the Apple Watch enhanced with new sections for exercise stress and diastolic stress echocardiography.
• “Organizations” section of the EchoLab in-app Guide expanded to include links to 30 echocardiography-related entities worldwide.
• Listed reference ranges for left ventricular mass index corrected to show linear measurement ranges, not 2D measurement ranges (Analytic Engine has been using linear ranges for assessment of left ventricular mass, as intended).
• Deprecated 2014/2017 ACC/AHA guidelines for valvular heart disease removed from the Analytic Engine.
