简要总结
Prospective non-randomized parallel-assignment multi-center clinical investigation. The study design includes two subject cohorts: 1) Paroxysmal Atrial Fibrillation Main Study, and 2) Paroxysmal Atrial Fibrillation High Standard Power Substudy. Subjects in the main study cohorts are to be treated using the full range of ablation power settings in the Instructions For Use. Subjects in the High Standard Power Substudy are to be treated in the upper end of the recommended ablation power settings (40-50 Watts).
详细描述
This clinical investigation is intended to demonstrate the safety and effectiveness of the TactiFlex(TM) Ablation Catheter, Sensor Enabled(TM) (TactiFlex SE) for treating drug-refractory, symptomatic paroxysmal atrial fibrillation. This clinical investigation will be conducted under an investigational device exemption and is intended to support market approval of the TactiFlex SE catheter worldwide. Three hundred and Fifty Five (355) subjects will be enrolled at up to 50 investigational sites worldwide. This clinical investigation is sponsored by Abbott.

结局指标
主要结局
Number of Participants With Device or Procedure-related Serious Adverse Events
时间窗: Through 12 months
Tthe rate of device and/or procedure-related serious adverse events with onset within 7-days of any ablation procedure that uses the TactiFlex SE catheter (initial or repeat procedure performed 31-80 days of initial procedure) that are defined below: * Atrio-esophageal fistula1 * Cardiac tamponade/perforation1 * Death * Heart block * Myocardial infarction * Pericarditis * Phrenic nerve injury resulting in diaphragmatic paralysis * Pulmonary edema * Pulmonary vein stenosis1 * Stroke/cerebrovascular accident * Thromboembolism * Transient ischemic attack * Vagal nerve injury/gastroparesis * Vascular access complications (including major bleeding events) 1. Atrio-esophageal fistula, cardiac tamponade/perforation and pulmonary vein stenosis will be evaluated through 12-months.
KM Rate of Freedom From Atrial Fibrillation, Atrial Flutter or Atrial Tachycardia Recurrence
时间窗: Through 12 months
Freedom from documented (symptomatic or asymptomatic) Atrial Fibrillation/Atrial Flutter/Atrial Tachycardia episodes of \>30 seconds duration that are documented by 12-lead ECG, transtelephonic monitoring or Holter monitor after the initial catheter ablation procedure through 12-months of follow-up. Recurrence during the 90-day blanking period will not be considered a treatment failure. One repeat procedure will be allowed during the blanking period. Failure to achieve acute procedural success during the last ablation procedure with the TactiFlex SE catheter will constitute failure. After the 90-day blanking period, use of Class I or III anti-arrhythmic drugs will not count as a therapy failure provided that only previously failed drugs are taken at doses that do not exceed the previously failed dose.
次要结局
- KM Rate of Freedom From Symptomatic Atrial Fibrillation, Atrial Flutter or Atrial Tachycardia Recurrence(Through 12 months)
- KM Rate of Freedom From Atrial Fibrillation, Atrial Flutter or Atrial Tachycardia Recurrence With Only 1 Ablation Procedure(12 months)
- KM Rate of Freedom From Atrial Fibrillation, Atrial Flutter or Atrial Tachycardia Recurrence, Without Anti-arrhythmic Drugs(Through 12 months)
