Why do we Need ICE?

The main advantages and disadvantages of ICE are outlined in table 1 . Traditionally, percutaneous ASD and PFO closures are performed under TOE guidance using general anaesthesia. There are clear imaging benefits from visualising the atrial septum from within the heart, particularly the visualisation of the inferior rim of the septum. More importantly, as the ICE probe can be inserted percutaneously, only local anaesthetic is required, sparing the patient from the risks and costs of general anaesthesia. Using a local anaesthetic approach and with the additional imaging quality, atrial septal closure under ICE guidance is performed with lower radiation doses, with shorter procedure times and with faster turnaround than with TOE.[23,24,25] There is no reported increase in vascular complications from the additional venous puncture. With smaller 8F catheters being released, this concern should reduce further. Transient atrial arrhythmias have been reported from manipulation of the ICE catheter in the right atrium.
