Treatment and study plan

OPTRELL Mapping Catheter

Device

Participants scheduled to have a clinically-indicated catheter mapping and ablation using OPTRELL mapping catheter for the management of Atrial procedure (Scar-related Atrial Tachycardia, Persistent Atrial Fibrillation, Paroxysmal Atrial Fibrillation) and Ventricular procedures (Ventricular Tachycardia, Premature Ventricular Complex).

Primary outcomes

  1. Number of Participants With Serious Adverse Events (SAEs) Within 7 Days of Index Procedure Related to the OPTRELL Catheter

    Time frame: Up to 7 days of index procedure at Day 0

    Number of participants with SAEs within 7 days of index procedure related to the OPTRELL catheter were reported. An adverse event (AE) is any untoward medical occurrence in a participant whether or not related to the investigational device. SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize participant and/or may require medical or surgical intervention to prevent one of the outcomes listed above.

  2. Number of Participants With Pre-ablation Mapping and Clinically Indicated Mapping Performed With the OPTRELL Catheter Without Resort to Other Mapping Catheters

    Time frame: Up to 72 days

    Number of participants with pre-ablation mapping and clinically indicated mapping performed with the OPTRELL catheter without resort to other mapping catheters were reported.

Secondary outcomes

  1. Number of Participants With SAEs Within 7 Days of Index Procedure

    Time frame: Up to 7 days of index procedure at Day 0

    Number of participants with SAEs within 7 days of index procedure were reported. An AE is any untoward medical occurrence in a participant whether or not related to the investigational device. SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect and may jeopardize participant and/or may require medical or surgical intervention to prevent one of the outcomes listed above.

  2. Number of Participants With Non-serious Adverse Events Within 7 Days of Index Procedure Associated With the Use of the OPTRELL Catheter

    Time frame: Up to 7 days of index procedure at Day 0
