Perioperative Echo (pEcho) is an evidence based, procedure oriented decision support tool aimed at anesthesiologists and other providers performing transesophageal echocardiography (TEE) in the perioperative setting.

*******************************

This app is organized by procedures. If you're starting an aortic valve replacement surgery, open the aortic valve section and start inputing values to assess the severity of the aortic valve pathology. These values can be used to calculate valve area and even troubleshoot replacement valves. Levels of evidence based off of publications from Journal of American Society of Echocardiography (JASE) and American Heart Association (AHA), are listed within the app.

The app includes the following sections and metrics:

Aortic valve replacement/repair:
Aortic stenosis: peak velocity, mean gradient, valve area via continuity equation, dimensionless index (DVI)

Aortic regurgitation: vena contracta, pressure half-time, jet diameter to LVOT diameter %

- Much more, including an evidence based decision support tool for determining if a heart valve should be replaced.

Mitral valve replacement/repair:
Mitral regurgitation
- Vena contracta
- Estimated regurgitant orifice area via PISA
- Regurgitant volume
- Regurgitant fraction

Mitral stenosis
- Mean gradient
- Valve area via pressure half-time
- Estimated orifice area via PISA
- Much more, including an evidence based decision support tool for determining if a heart valve should be replaced.

Coronary artery bypass:
- LV wall motion interactive tool with corresponding coronary artery distribution
- Right ventricular fractional area change
- Diastology tools

Rescue TEE (Non-cardiac TEE)
Images and instructions on how to diagnose the following:
- Myocardial ischemia
- Pulmonary embolism
