Our aim was to compare the different methods of
modeling the effect of circulating blood flow on the thermal lesion
dimensions created by radio frequency (RF) cardiac ablation and
on the maximum blood temperature. ...

Purpose: To assess by means of computer simulations whether the heat sink effect inside a large vessel (portal vein) could protect the vessel wall from thermal damage close to an internally cooled electrode during ...
[EN] Purpose
To assess the effect of intracardiac blood flow pulsatility on tissue and blood distributions during radiofrequency (RF) cardiac ablation (RFCA).
Methods
A three-dimensional computer model was used to ...
