Structured PICO

Does monitoring catheter tip temperature improve the prediction of lesion size during radiofrequency ablation in canine ventricular myocardium?

P
Population
Isolated ventricular preparations from freshly excised dog hearts (in vitro) and 12 anaesthetized dogs (in vivo)
I
Intervention
Transcatheter radiofrequency application (500 kHz, 10 s pulse duration) with monitoring of catheter tip temperature using 6F USCI catheters with built-in thermoelement
O
Outcome
Correlation between lesion volume and delivered radiofrequency energy, maximum changes in catheter tip temperature, and the integral of the temperature curvesurrogate

Monitoring catheter tip temperature, particularly the temperature integral, during radiofrequency energy application improves the prediction of lesion size and may enhance procedural safety.
