We've reached the last of our 5 Steps! In this step, we will discuss a single finding that if present, has a 90% chance of an associated cardiac anomaly, whether you see it or not!
In Step 1, we described a system to identify the chambers that works in all planes and orientations
In Step 2, we found how to compare chamber sizes and use these to our advantage
In Step 3, we used heart position to help us predominantly identify extracardiac abnormalites
In Step 4, we used discussed using the cardiac axis to alert us to subtle extra and intracardiac anomalies
As always, Thanks for watching
