The purpose of this study is to collect information about how safe Dual Energy THERMOCOOL SMARTTOUCH™ SF (DE STSF) catheter with TRUPULSE™ Generator is and how effective a specific procedural workflow is when this ablation system is used to treat ventricular arrhythmias. The main aims of this study are to see whether the abnormal heart rhythm can be successfully treated while maintaining a specific procedural workflow with the catheter and generator during the cardiac ablation and to monitor participant safety after the procedure by checking if the participant has any complications.
Participant is planned for a catheter ablation procedure to ablate either: (a) Premature ventricular complexes (PVCs); (b) Sustained monomorphic ventricular tachycardia (VT), including sustained monomorphic ischemic ventricular tachycardia (SMIVT) or sustained monomorphic non-ischemic ventricular tachycardia (SMNIVT), with one or more documented spontaneous episodes of symptomatic sustained monomorphic ventricular tachycardia within 3 months that required device therapy (shock or anti-tachycardia pacing), external cardioversion, escalated antiarrhythmic therapy, and/or hospitalization. Documented episodes will be assessed by review of electrocardiographic data.
Age greater than or equal to 18 years
Willing and capable of providing consent
Able and willing to comply with all pre-, post-, and follow-up testing and requirements
Incessant ventricular arrhythmia (VA) necessitating hemodynamic support prior to the ablation procedure
Polymorphic ventricular tachycardia, unstable ventricular tachycardia, or ventricular fibrillation (VF)
Idiopathic VTs
Suspected reversible cause of VA (example, electrolyte abnormalities, thyroid disease, drug induced arrhythmia)
Single group
Radiofrequency/Pulsed Field Ablation System
DeviceRadiofrequency and pulsed field ablation by Dual Energy THERMOCOOL SMARTTOUCH™ SF (DE STSF) catheter with the TRUPULSE™ generator will be used.
PVC Arm: Effectiveness of the Procedural Workflow
Effectiveness of the procedural workflow for PVC arm is defined as reduction in burden at 3 months after the index ablation procedure compared to the baseline burden. PVC burden is defined as the percentage of PVCs relative to the total heartbeats measured during a 24-hour Holter monitoring.
SMIVT and SMNIVT arms: Effectiveness of the Procedural Workflow
Effectiveness of the procedural workflow for SMIVT and SMNIVT arm is defined as freedom from documented recurrence (symptomatic or asymptomatic) of any monomorphic VT based on electrocardiographic data (Holter or \>= 30 seconds on ECG or any appropriate ICD therapy) throughout 6 months after the index ablation procedure.
Occurrence of Primary Adverse Events (PAE)
Occurrence of PAEs within 7 days of the index ablation procedure where the DE STSF Catheter and TRUPULSE Generator are used will be reported. PAEs include the following adverse events: cardiac tamponade/perforation, phrenic nerve paralysis (permanent), device or procedure related death, stroke/cerebrovascular accident (CVA), major vascular access complication/bleeding, thromboembolism, myocardial infarction (MI), transient ischemic attack (TIA), pericarditis, heart block, pulmonary edema (respiratory insufficiency), vagal nerve injury/gastroparesis, aggravation or new onset heart failure, coronary artery injury, aortic dissection, and valve injury.
Occurrence of Serious Adverse Device Effects (SADEs)
A SADE is an adverse device effect that has resulted in any of the consequences characteristic of a serious adverse event (SAE). A SAE is any event that led to any of the following: Death, 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 and fetal distress, fetal death or a congenital physical or mental impairment or birth defect.
Occurrence of Unanticipated Serious Adverse Device Effects (USADEs)
An USADE is any SAE on health, safety, any life-threatening problem, or death caused by, or associated with a device, if that effect, problem, or death was not previously identified in nature, severity, outcome, or degree of incidence in the current investigational plan or risk analysis report, or any other unanticipated serious problem associated with a device that relates to rights, safety, or welfare of participants.
Occurrence of SAEs
An SAE is any event that led to any of the following: Death, 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 and fetal distress, fetal death or a congenital physical or mental impairment or birth defect.
Occurrence of Non-Serious Adverse Events (Non-SAEs)
An Adverse Event (AE) means any untoward medical occurrence, unintended disease or injury or any untoward clinical signs, including an abnormal laboratory finding, in participants, users or other persons, in the context of a clinical investigation, whether or not related to the investigational device.
