Real-world Experience of Catheter Ablation for the Treatment of Paroxysmal and Persistent Atrial Fibrillation

Recruiting
Conditions
Persistent Atrial Fibrillation
Paroxysmal Atrial Fibrillation
Registration Number
NCT04088071
Lead Sponsor
Heart Rhythm Clinical and Research Solutions, LLC
Brief Summary

The primary purpose of this registry is to obtain real-world clinical experience of Paroxysmal (PAF) and Persistent (PsAF) Atrial Fibrillation ablation radiofrequency (RF) technologies. Data from the registry will be used to assess clinical outcomes, including procedural efficiency, safety, and long-term, effectiveness of catheter ablation with novel RF technologies in PAF and PsAF patients.

Detailed Description

The REAL AF Registry is an observational, prospective, multi-center, non-randomized registry designed to obtain real-world clinical experience of Paroxysmal and Persistent ablation RF technologies (e.g., THERMOCOOL SMARTTOUCH®, THERMOCOOL SMARTTOUCH® SF). Future new contact force technologies may be included as they become available in the market. Patient assessments will occur at the following time points: 1) pre-ablation, 2) procedure, 3) 10-12 weeks, 4) 6 months (monitor only) and 5) 1 year post ablation.

The objective of this registry is to assess clinical outcomes, including procedural efficiency, safety, long-term, effectiveness of RF ablations in the treatment of patients with Paroxysmal or Persistent atrial fibrillation. The outcomes of the registry are: 1) long term effectiveness defined as freedom from atrial arrhythmia recurrence post 90 day blanking period, and 2) acute and late onset complications.

Sites selected for this registry will already have the following pre and post procedure assessments as part of their standard of care:

Patient assessments at the following time points: (1) pre-ablation or baseline, (2) procedure, (3) 10-12 weeks, (4) 6 months (monitor only) and (5) 1 year post ablation.

Pre ablation/baseline assessment should include: TTE (within 6 months of procedure), CHADS2Vasc, sleep apnea, AAD status, OAC, Medical and Arrhythmia History 10-12 Week Follow-Up Office Visit: Physician evaluation, AAD status, OAC usage, repeat TTE, and Arrhythmia Reoccurrence and Treatment Assessment Monitoring: 96-hour continuous heart rhythm monitor scheduled at 6 months and 12 months post ablation, with an event monitor ordered as needed for symptomatic arrhythmias.

12 Month Follow up Office Visit: Physician evaluation, AF Type, AF Monitoring method, Sleep apnea, Post-procedure arrhythmia treatments, AF related symptoms and QOL improvement, AAD and OAC usage, CHA2DS2VASC and Arrhythmia Reoccurrence and Treatment Assessment

Exclusion Criteria
  • Enrolled in an investigational drug or device clinical trial, or any trial that dictates the treatment plan

How do you feel now compared to pre-ablation?

AF related symptoms12 months

Presence of: weakness, fluttering, SOB, fatigue, dizziness, decrease in exercise tolerance, chest pain/pressure, heart racing/palpitations, and other (yes/no)

CHA2DS2VASC12 months

An estimation of stroke risk for patients with Atrial Fibrillation. Composite score of: Age (\<65= 0; 65-74=1; \>75=2) + Sex (Female=1; Male=0) + Congestive Heart Failure (Yes =1; No=0) + Hypertension (Yes= 1; No= 0) + Stroke, Transient Ischemic Attack (TIA) or thromboembolism (Yes=2; No=0) + Vascular Disease (Yes=1; No=0) + Diabetes (Yes=1; No=0). Scores range from 0 to 9, with higher scores indicating greater risk for stroke.
