简要总结
To evaluate the safety and efficiency of the Arga Medtech CSE Ablation System in the treatment of atrial fibrillation.
详细描述
A prospective, single-arm, multi-center, multi-national, non-randomized study designed to provide clinical data to support the use of the Arga Medtech System in the ablation of atrial fibrillation.
Patients with paroxysmal AF will be treated using the Arga Medtech System to achieve pulmonary vein isolation (PVI) (and cavo-tricuspid isthmus (CTI) ablation as appropriate if history of CTI flutter or inducible flutter during procedure)
Patients with persistent AF will be treated using the Arga Medtech System to achieve PVI and posterior wall (PW) ablation (CTI ablation as above).
Patients will be remapped at 90 days post the index procedure to confirm absence of PV reconnection and durability of any additional lesion sets performed. Re-ablation is permitted during the remapping procedure if indicated. Re-ablation resets the 90-day blanking period.
Additional follow-ups will be conducted at 7 days, 30 days, 180 days and 360 days post the index or re-ablation procedure.

入选标准
- •Scheduled for ablation of paroxysmal or persistent AF
- •Willingness, ability, and commitment to participate in baseline and follow-up evaluations for the duration of the study
- •Willing and able to give informed consent
- •Failed at least one antiarrhythmic drug (AAD) (Class I to IV) as evidenced by recurrent symptomatic AF or intolerable or contraindicated to the AAD
排除标准
- •Contraindication to AF ablation, TEE or anticoagulation
- •Duration of continuous AF lasting longer than 12 months
- •History of previous LA ablation or surgical treatment of AF/AT/AFL
- •AF secondary to electrolyte imbalance, thyroid disease, or any other reversible or non-cardiac cause
- •Structural heart disease described as:
- •LVEF <30% based on TTE within 6 months of procedure
- •Left atrial size > 50mm based on TTE within 6 months of procedure (parasternal view)
- •An implanted pacemaker or ICD
- •Previous cardiac surgery, ventriculotomy, or atriotomy (excluding atriotomy for CABG)
- •Previous cardiac valvular surgical or percutaneous procedure or prosthetic valve
- •Interatrial baffle, closure device, patch, ASD or PFO
- •Presence of a left atrial appendage occlusion device
- •CABG or PTCA procedure within the last 6 months
- •Unstable angina or ongoing myocardial ischemia
- •Myocardial infarction within the previous 6 months
- •Hypertrophic cardiomyopathy defined as left ventricular septal wall thickness > 1.5cm
- •History of blood clotting or bleeding disease
- •Prior history within the previous 6 months of documented cerebral infarction, TIA or system embolism
- •Pregnant or lactating (current or anticipated within study follow-up)
- •Current enrollment in any other study protocol where testing or results from that study may interfere with the procedure or outcomes measurement for this study
- •Any other condition, in the judgment of the investigator, makes the patient a poor candidate for this procedure, the study or compliance with the protocol
结局指标
主要结局
Procedural Success
时间窗: Acute and/or up to 90 days post procedure
Number of patients that achieve procedural success defined as isolation of the pulmonary veins at the index or re-mapping procedure.
Chronic isolation of the pulmonary veins
时间窗: 90 to 180 days post index procedure
Rate of patients and targeted pulmonary veins with documented electrical isolation of the pulmonary veins, assessed by entrance and exit block during a mapping procedure \~90-days post procedure.
Serious system and procedure-related events
时间窗: Within one week (7 days) post-procedure)
Incidence of system-related and procedure-related serious adverse events (SAEs).
