EchoLab presents the formulas and algorithms commonly used in the day-to-day operation of an echocardiography laboratory. Designed by a practicing cardiologist and echocardiographer, EchoLab provides a comprehensive framework for teaching the principles of quantitative echocardiography, or cardiac ultrasound, by demonstrating in detail the inter-relationships between these formulas. EchoLab is unique as an application for echocardiography in its wide scope and with its sharing of entered and calculated data between its many formulas (users do not need to re-enter data when shifting to a new calculation). EchoLab also displays all entered and calculated data with an assessment of each variable as normal or abnormal by adult criteria, if relevant. Available with each formula is a graphical display of the corresponding mathematical equation, along with tips for using the calculation and a reference to the medical literature.
An integrated, user-customized library allows viewing of files downloaded from the Web, uploaded from the user's computer using iTunes file sharing, imported as E-mail attachments, transferred from the photo album, or captured with the camera. Store scientific papers, slideshows, movies, photographs, schematics, and spreadsheets for convenient reference and teaching. Send any library file to a colleague as an E-mail attachment with a simple touch.
Calculations included in the application include:
• Aortic effective regurgitant orifice area
• Aortic regurgitant fraction
• Aortic regurgitation index (for TAVI, from invasive pressure measurements)
• Aortic root assessment
• Aortic valve area (from velocity and velocity-time integral)
• Aortic valve resistance
• Body mass index
• Body surface area
• Cardiac output and ejection fraction (area-length, Doppler, Dumesnil, Teichholz, and directly entered volume methods), with comparison of calculations among the methods
• Diastology assessment algorithm (qualitative assessment of left atrial pressure and left ventricular diastolic function)
• Hemodynamic summary
• Left atrial pressure
• Left atrial volume and index
• Left ventricular diastolic diameter index
• Left ventricular dP/dt

• Left ventricular myocardial performance index
• Maximum predicted heart rate (for dobutamine and exercise stress echocardiography)
• Maximum rate-pressure product (for exercise stress echocardiography)
• Mean arterial pressure
• Mitral effective orifice area (PISA and stroke volume methods)
• Mitral regurgitant fraction (PISA and stroke volume methods)
• Mitral valve area (continuity, PISA, and pressure half-time methods)
• Mitral valve resistance
• Mitral valvuloplasty score
• Pulmonary artery systolic pressure (using tricuspid regurgitant velocity, VSD flow velocity, or pulmonary artery acceleration time)
• Pulmonary artery diastolic pressure
• Pulmonary artery mean pressure

• Pulmonary vascular resistance
• Right atrial pressure
• Right ventricular dP/dt
• Right ventricular myocardial performance index
• Shunt ratio (Qp:Qs)
• Systemic vascular resistance

Note that EchoLab is a teaching and reference application, not a tool for clinical diagnosis, clinical decision-making, or echocardiography report generation.
Novità nella versione 3.2
Calculation added for pulmonary artery systolic pressure derived from pulmonary artery acceleration time (useful when tricuspid regurgitation is absent or insufficient).
