This lecture discusses basic and advanced hemodynamic calculations. ERROR: Hemodynamics Part 1 at 16:28. In the table it should say: Moderate regurgitant volume 30-59 ml and severe >60ml error at time 19:55: ROA = RVOL / TVI = 13.1/191 = 0.69 cm2 Special thanks to Keith Levendorf, Doug Carrie and others who alerted us to the errors. We will re-record the lecture and remove the error when time permits. Sorry for the mistake.
