6 mm cryocatheter use was associated with lower AVNRT recurrence; extends observational data but leaves open randomized confirmation before practice change.
Does a 6 mm cryocatheter reduce recurrence rates compared to a 4 mm cryocatheter in patients undergoing cryoablation for AVNRT?
The use of a larger 6 mm cryocatheter and achieving complete slow pathway block significantly reduces long-term recurrence rates in patients undergoing cryoablation for AVNRT.
