Outcome Measures
Primary Outcomes (2)
Incidence of Serious Adverse Events (SAEs) Within 7 Days of Index Procedure Related to the Investigational Catheter When Used for Endocardial Mapping
A SAE is any AE that led to any of the following: (1) Death; (2) Serious deterioration in the health of a participant that resulted in any of the following: Life-threatening illness or injury; Permanent impairment of a body structure or a body function; In-patient hospitalization or prolongation of patient hospitalization; Medical or surgical intervention to prevent life-threatening illness or injury or permanent impairment to body structure or a body function; Chronic disease. (3) Fetal distress, fetal death or a congenital physical or mental impairment or birth defect.
Up to 7 days post index procedure
Incidence of Completion of All Pre-Ablation Endocardial Mapping Requirements and Any Clinically Indicated Endocardial Mapping
Incidences of all pre-ablation endocardial mapping requirements and any clinically indicated endocardial mapping with the investigational catheter, without resort to non-investigational mapping catheter due to an inadequacy or inability of the investigational catheter to perform the required arrhythmia mapping will be reported.
Up to 7 days post index procedure
Secondary Outcomes (5)
Investigator Assessment of Deployment; Visualization; Maneuverability and Signal Quality
Up to 7 days post index procedure
Incidence of SAEs Related to the Investigational Catheter When Used for Epicardial Mapping as per Physician's Discretion
Up to 7 days post index procedure
Incidence of all Other SAEs Not Related to the Investigational Catheter
Up to 7 days post index procedure
Incidence of Non-serious Adverse Events (AEs) Related to the Investigational Catheter
Up to 7 days post index procedure
Incidence of Completion of all Pre-ablation Epicardial Mapping Requirements and Any Clinically Indicated Epicardial Mapping With the Investigational Catheter as Per Physician's Discretion
Up to 7 days post index procedure
Study Arms (1)
Arrhythmia Mapping by a Paddle-shaped, High-density, Multi-electrode Mapping Catheter
EXPERIMENTALParticipants scheduled to have a clinically indicated catheter mapping and ablation procedure for management of a cardiac arrhythmias will undergo catheter mapping and ablation procedure using paddle-shaped, high-density, multi-electrode mapping catheter.
Interventions
High-density, multi-electrode mapping catheter will be used for the procedure.
Eligibility Criteria
You may qualify if:
- Diagnosed with and candidate for clinically indicated catheter mapping and ablation procedure for the management of ventricular tachycardia, premature ventricular complex, atrial tachycardia or atrial fibrillation (participant having undergone a previous ablation procedure may be included)
- At least one episode of the targeted arrhythmia (ventricular tachycardia, premature ventricular complex, atrial tachycardia or atrial fibrillation) must have been documented by electrocardiogram (ECG), Holter, loop recorder, telemetry, implanted device, or transtelephonic monitoring within 12 months prior to enrollment
- Age 18 years or older
- Signed Patient Informed Consent Form (ICF)
- Able and willing to comply with all pre-, post-, and follow-up testing and requirements
You may not qualify if:
- Study arrhythmia secondary to reversible cause, or secondary to electrolyte imbalance, thyroid disease, or non cardiac cause
- Patients requiring left atrial procedures: left atrial size greater than (\>) 55 millimeter (mm)
- Left ventricular ejection fraction(LVEF) less than or equal to (\<=) 25 percentage (%) for participants with ventricular arrhythmia
- LVEF \<= 40% for participants with atrial arrhythmia
- Documented intracardiac thrombus as detected on imaging within 24 hours prior to insertion of the investigational catheter
- Contraindication to anticoagulation (that is, heparin, warfarin, dabigatran)
- History of blood clotting or bleeding abnormalities (example hypercoagulable state)
- Myocardial infarction within the past 2 months (60 days)
- Documented thromboembolic event (including transient ischemic attack \[TIA\]) within the past 12 months (365 days)
- Uncontrolled heart failure or New York heart association (NYHA) function class IV
- Implanted with a pacemaker or intracardiac cardiac defibrillator or appendage closure device within the past 6 weeks (42 days)
- Patients with known untreatable allergy to contrast media
- Active illness or active systemic infection or sepsis
- Diagnosed atrial or ventricular myxoma, interatrial baffle or patch, tumor or other abnormality that precludes catheter introduction or manipulation
- Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment in this study
