Purpose
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.

- Number of Participants with Successful Procedures and No AtrioVentricular Nodal Reentrant Tachycardia Recurrence [ Time Frame: 6 months ] [ Designated as safety issue: No ]
Subjects must meet both of the following conditions to be considered as a chronic effectiveness success:
- The inability to induce more than one echo beat by the same pacing maneuvers that induced atrioventricular nodal reentrant tachycardia (AVNRT) before cryoablation (with drug provocation if required for induction before cryoablation) at the conclusion of the ablation procedure assessment (i.e. acute procedural success)
- Lack of documented recurrence of clinical AVNRT during the 6 months follow-up period post the successful ablation procedure
- Number of Participants with Adverse Events as a Measure of Safety [ Time Frame: 6 Months ] [ Designated as safety issue: No ]The primary safety endpoint is a success/failure variable calculated for each subject through 6 months follow-up. Subjects with at least one chronic safety event (serious adverse event determined to be ablation procedure or device related) during the cryoablation procedure and through the end of 6 months follow-up will be considered a primary safety failure.
- Number of Participants who had Acutely Successful Procedures and No Atrioventricular Nodal Reentrant Tachycardia Recurrence. [ Time Frame: 6 Months ] [ Designated as safety issue: No ]Demonstrate the chronic effectiveness (Lack of documented recurrence of clinical atrioventricular nodal reentrant tachycardia) of the Freezor® Xtra CryoAblation Catheter in the treatment of atrioventricular nodal reentrant tachycardia through 6 months in subjects who have achieved acute procedural success.

- 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)
