(a) Blood flow velocity distributions in (a.left) the monopolar catheter configuration and (a.right) the bipolar catheter configuration, (b) maximum temperature over time in (b.left) the monopolar catheter configuration and in (b.right) the bipolar catheter configuration. Maximum temperatures predicted for blood and cardiac tissue in RFA (dashed lines) and in PFA (solid lines) and (c) geometry and boundary conditions used for the monopolar and bipolar configurations. Electrical (blue), thermal (red) and fluid dynamics (white) boundary conditions are indicated for both catheter configurations. In (d) and (e) a magnification of the contact points is depicted for the monopolar and bipolar catheter configurations, respectively.
