Not useful as a learning tool
I presume this app (at least this lite version) is simply a taste of what the full version offers. It only has 10 sample videos and very limited explanation of each video. That renders it pretty useless as a learning tool. Sure, its "cool" to see images of a procedure, but you can find that all over the internet, and for those of us in medicine who would like to learn more about what it is that we are viewing, this app does not further our knowledge in interventional cardiology.
So, for now - I would label this app merely as "eye candy", and a very small candy at that.
