Function and Flow- Making sense of the numbers: Complex Flow Calculations

Video Transcription

Video Summary

The talk explains how to calculate blood-flow shunts in congenital heart disease using atrial septal defect (ASD), ventricular septal defect (VSD), and patent ductus arteriosus (PDA) as building blocks. It shows how comparing aortic, pulmonary, ventricular, and venous flows reveals left-to-right shunts and chamber volume overload. The speaker first works through each defect separately, then combines all three in one complex case. By measuring flow distal or proximal to shunts appropriately, the total shunt and each defect’s contribution can be estimated. Main message: approach complex flow calculations methodically, one step at a time.
