Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Irreversible Electroporation (IRE) System
Participants with symptomatic drug refractory paroxysmal atrial fibrillation (PAF) and indicated for catheter ablation will be treated with the IRE system which includes multi-electrode circular IRE catheter and the multi-channel IRE generator.
Device: Multi-Channel Irreversible Electroporation (IRE) Generator
The multi-channel IRE Generator is intended for use during cardiac Pulsed Field Ablation (PFA) therapy. This device is used in conjunction with a compatible ablation catheter to create a closed electrical circuit capable of delivering pulsed electrical field energy.
Other Names:
  • D-1417-01-I
Device: Multi-Channel Circular IRE Catheter
The multi-channel circular IRE Catheter is indicated for use in catheter-based cardiac electrophysiological mapping (stimulating and recording) and when used with an IRE Generator, for cardiac ablation.
Other Names:
  • D-1412-01-SI

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Long-term Effectiveness
Time Frame: From Day 91 up to Day 365 post-procedure on Day 0
Long-term effectiveness was defined as freedom from documented asymptomatic and symptomatic atrial fibrillation (AF), atrial tachycardia (AT), or atrial flutter (AFL; of unknown origin) episodes based on electrocardiographic data (greater than equal to [>=] 30 seconds on arrhythmia monitoring device) through the effectiveness evaluation period (Day 91 through Day 365 post index procedure) and freedom from the following failure modes : freedom from acute procedural failure, freedom from non-study catheter failure, freedom from repeat ablation failure, freedom from direct Current (DC) cardioversion failure, freedom from recurrence (captured on 12-lead electrocardiogram [ECG]) failure, and freedom from anti-arrhythmic drug failure. AFL of unknown origin was defined as all AFL except those Cavo-Tricuspid Isthmus (CTI) dependent AFL as confirmed by accepted electrophysiology (EP) maneuvers (for example, entrainment or activation mapping) in an EP study.
From Day 91 up to Day 365 post-procedure on Day 0

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Experiencing Primary Adverse Event (PAE)
Time Frame: Within 7 days post-procedure on Day 0
Percentage of participants experiencing PAE were reported. An AE is any untoward medical occurrence in a participant whether or not related to the investigational medical device. Primary AEs within seven days of the ablation procedure which used investigational devices per protocol, including the initial and repeat procedures were reported. PAEs included cardiac tamponade, perforation, myocardial infarction, stroke/cerebrovascular accident, thromboembolism, transient ischaemic attack, phrenic nerve injury/diaphragmatic paralysis, heart block, pulmonary vein stenosis, pulmonary oedema (respiratory insufficiency), vagal nerve injury/gastroparesis, pericarditis, major vascular access complication/bleeding, and atrio-esophageal fistula .
Within 7 days post-procedure on Day 0
Percentage of Participants Experiencing Serious Adverse Event (SAE) Within 7 Days, 8-30 Days and >30 Days of Initial Ablation Procedure
Time Frame: From day of procedure (Day 0) up to 12 months
Percentage of participants with SAEs within 7 days (early-onset), 8-30 days (peri-procedural) and >30 days (late onset) of initial ablation procedure were reported. A SAE was any adverse event (AE) that resulted in a death or a serious deterioration in the health of the participant during the clinical trial, including a life-threatening illness or injury, a permanent impairment of a body structure or a body function, in-patient hospitalization or prolongation of existing hospitalization, medical or surgical intervention to prevent permanent impairment of a body structure or a body function; or resulted in fetal distress, foetal death or congenital abnormality, congenital anomaly, etc.
From day of procedure (Day 0) up to 12 months
Percentage of Participants With Acute Procedural Success
Time Frame: On the day of procedure (Day 0)
Percentage of participants with acute procedural success were reported. Acute procedural success was defined as confirmation of entrance block in all clinically relevant targeted pulmonary veins (PVs) after adenosine/ isoproterenol challenge. Touching up with focal catheter was considered as acute procedural failure.
On the day of procedure (Day 0)
Percentage of Participants With Acute Reconnection
Time Frame: On the day of procedure (Day 0)
Percentage of participants with acute reconnection were reported. Acute reconnection was identified by adenosine/isoproterenol challenge among all clinically relevant targeted PVs and by participant.
On the day of procedure (Day 0)
Percentage of Pulmonary Veins (PVs) With Acute Reconnection
Time Frame: On the day of procedure (Day 0)
Percentage of PVs with acute reconnection were reported. Acute reconnection was identified by adenosine/isoproterenol challenge among all clinically relevant targeted PVs and by participant.
On the day of procedure (Day 0)
Percentage of Participants With Pulmonary Vein (PV) Ablation
Time Frame: On day of procedure (Day 0)
Percentage of participants with PV ablation by a non-study catheter (touch-up) among all clinically relevant targeted participants were reported.
On day of procedure (Day 0)
Percentage of Participants With Repeated Ablation
Time Frame: From the day of procedure (Day 0) up to 12 months
Percentage of participants with repeated ablation within the 12 months follow up period, including timing (blanking period or after blanking) were reported. Repeat procedures for AF/AT/AFL of unknown origin plus recurrences during the blanking period (90 days post index procedure) were conducted with the investigational device for ablating PV reconnections. Repeat procedures performed after the blanking period were managed per investigator discretion using a commercially available ablation catheter and generator.
From the day of procedure (Day 0) up to 12 months
