ICY-AVNRT (Intracardiac CrYoablation for AtrioVentricular Nodal Reentrant Tachycardia)
ICY-AVNRT (Intracardiac CrYoablation for AtrioVentricular Nodal Reentrant Tachycardia) is a
prospective multi-center, nonrandomized, single arm, controlled, unblinded, investigational
clinical study. The purpose of this clinical study is to demonstrate the safety and
effectiveness of the Freezor® Xtra Cardiac CryoAblation Catheter for the cryoablation of the
conducting tissues of the heart in the treatment of patients with atrioventricular nodal
reentrant tachycardia (AVNRT) using an endocardial approach.

Pre-Electrophysiology Study Inclusion Criteria:
- Supraventricular tachycardia (SVT) compatible with atrioventricular nodal reentrant
tachycardia (AVNRT), documented by ECG, TTM, Holter or event monitor
Pre-Electrophysiology Study Exclusion Criteria:
- History of sustained (≥30 seconds) of ventricular tachycardia
- Atrial tachycardia or other arrhythmia that could be confused with AVNRT
- Reversible cause of SVT
- History of previous AVNRT ablation
- Therapy with amiodarone within last 90 days
- Unstable angina/myocardial infarction/open heart surgery in past 60 days
- New York Heart Association (NYHA) Classification III or IV currently or within the
past 90 days
- Implantable cardiac rhythm device
- Atrioventricular block (first degree (PR interval ≥ 220ms), second degree, or third
degree) or left bundle branch block
- Stroke or transient ischemic attack within the past 180 days
- Life expectancy less than 12 months
- Female known to be pregnant
- Unable/unwilling to give informed consent
- Unable/unwilling to comply with follow-up visits and study requirements
- Less than 18 years of age
- Active systemic infection
- Cryoglobulinemia
- Other conditions where the manipulation of the catheter would be unsafe (for example,
intracardiac mural thrombus)
- Participating in a concurrent clinical study that may confound the results of this
study
Post-Electrophysiology Study Inclusion Criteria:
- Subject must have one electrophysiology study documented inducible sustained (greater
than or equal to 15 seconds) supraventricular tachycardia that is classified as AVNRT.
Post-Electrophysiology Study Exclusion Criteria:
- Presence of a second inducible arrhythmia that could be confused with AVNRT during
follow-up or will likely result in ablation within the next 6 months
- Presence of inducible sustained ventricular tachycardia or fibrillation
- Presence of an accessory pathway
- Presence of abnormal conduction or refractoriness parameters of the atrioventricular
conduction system.
- Indication for a pacemaker, defibrillator or cardiac resynchronization therapy (CRT)
