Atrial Flutter Clinical Trial
Official title:
Determination of Catheter Contact by Evaluation of Microelectrode Near-Field Signals
Successful radio frequency (RF) cardiac catheter ablation requires the creation of lesions by delivering energy while maintaining adequate catheter contact with the endocardium. Unfortunately, it is difficult to identify contact intraoperatively as a typical RF ablation catheter lacks clear indications of contact. We propose to use the Boston Scientific IntellaTip MiFi catheter to explore whether characteristics of the electrograms produced by the mini-electrodes on the ablation tip could help confirm tissue contact. Using an ultrasound catheter to define instances of clear contact and non-contact, we will determine whether the micro-electrodes produce sufficient information to confirm catheter contact. We propose that the MiFi catheter produces sufficient signal characteristics that can be used as an effective surrogate for adequate tissue contact.
