CONCLUSIONS
In our pilot study, ICE performed better than IVUS with regards to imaging quality and inter-observer reproducibility of measurements obtained. Acute wall thickening was observed at the PV ostia after RF and laser energy delivery and not after cryoenergy delivery. Larger studies are needed to confirm these preliminary findings.
