Abstract:
The concept of an artificial interatrial communication in application of the Fontan procedure in high risk patients has raised the problem to exactly determine the shunt amount. This experimental study shows that in vitro flow studies of interatrial communications can be performed without animal blood and PTFE membranes respectively. Furthermore the simulation of an pulmonary vascular venous flow is not necessary. Additionally a new formula with acceptable accuracy for flow estimation is derived from the presented data obtained by this study.
