Rishi Kumar, MD, FACC ("developer", "me", "my", "I") is an adult cardiac anesthesiologist and cardiovascular intensive care physician working in academic medicine. My opinions expressed on this website are mine alone and do not represent the views of my current or former institutions of training and employment.

I am the owner and sole developer of EchoTools (the "application", "app"), its logo, and source code. EchoTools is freely provided "as is" with potential faults and errors. By using the app, you expressly agree that I am not responsible for any clinical decisions or outcomes.


The majority of this app’s content is from general guidelines and reference articles cited within the application itself. Patient identifiers have all been removed. Always consider the clinical context and technique of echocardiographic image acquisition before interpretation. As such, this app should not be used to diagnose any medical condition nor as a substitute for medical advice.

If you're interested in contributing a lesson with an ultrasound video clip or image, please contact me.
