The slope of the initial temperature drop predicts acute pulmonary vein isolation using the second-generation cryoballoon

ConclusionsAbout 25 s after freeze initiation, the temperature –time slope predicts important key characteristics of a cryoablation, such as nadir temperature. The slope is the only reported predictor to actually precede acute isolation and thus to support decisions about pull-down manoeuvres or aborting a cryoablation early on. It is also predictive of very low nadir temperatures and phrenic nerve palsy and thus may add to patient safety.
