Detailed Description
Arrhythmias, or abnormal heart rhythms, are a major cause of morbidity and mortality worldwide. In patients with arrhythmias, electrophysiology (EP) studies are often performed to assess the electrical system of the heart. Since its introduction in the 1990s, electroanatomic mapping has become a cornerstone of EP studies. Electroanatomic mapping systems allow for non-fluoroscopic navigation of the heart and the creation of three-dimensional (3D) anatomic and electroanatomic maps. These maps facilitate diagnosing and treating arrhythmias.
The NeuTrace System is a cardiac EP mapping system that is intended to be used during catheter-based atrial and ventricular mapping procedures. The system is designed to acquire and analyze data points and use this information to display 3D anatomical and electroanatomic mapping of the human heart. The system is used with a compatible, marketed magnetic sensor-enabled catheter and compatible EP recording system to acquire the location information and local electrogram needed to create the cardiac maps. The purpose of the trial is to evaluate physician acceptance and feasibility of the NeuTrace System v1.0 for cardiac electroanatomic mapping.

Outcome Measures
Primary Outcome Measures
- Physician rating of the electroanatomic map created by the NeuTrace System via a questionnaire [Immediately post-procedure]
At the completion of each electrophysiology study, the principal investigator will be asked to complete a questionnaire in which he or she qualitatively rates the electroanatomic map created by the NeuTrace System on a numeric scale from 1 to 5 (1 = not satisfied, 5 = very satisfied).
Secondary Outcome Measures
- Physician rating of catheter visibility during electroanatomic mapping with NeuTrace System via a questionnaire [Immediately post-procedure]
At the completion of each electrophysiology study, the principal investigator will be asked to complete a questionnaire in which he or she qualitatively rates the visibility of the catheter during electroanatomic mapping with the NeuTrace System on a numeric scale from 1 to 5 (1 = not satisfied, 5 = very satisfied).
- Physician rating of the accuracy of the anatomical map created with the NeuTrace System compared to an image obtained via computerized tomography, magnetic resonance imaging, or intracardiac echocardiography via a questionnaire [Immediately post-procedure]
Each participant will have an image obtained of their heart either pre-procedurally via computed tomography or magnetic resonance imaging, or intraprocedurally via intracardiac echocardiography. At the completion of each electrophysiology study, the principal investigator will be asked to complete a questionnaire in which he or she qualitatively rates the accuracy of the electroanatomic map created by the NeuTrace System with the image of the heart obtained via computerized tomography, magnetic resonance imaging, or intracardiac echocardiography.
- Measurement of the shift in the electroanatomic during the procedure with the NeuTrace System [Immediately post-procedure]
Shift refers to the movement of an electroanatomic map during the procedure (e.g., the patient moves in relation to the magnetic field). During each electrophysiology study, the principal investigator will annotate a point on the electroanatomic map with the NeuTrace System (X at time 1). The principal investigator will return to and again annotate that same point on the electroanatomic map 20 minutes later (X at time 2). The location of the point will be confirmed via intracardiac echocardiography. The distance between the points (X at time 1 and X at time 2) will be measured on the NeuTrace System in millimeters.
- Measurement of the drift in the electroanatomic during the procedure with the NeuTrace System [Immediately post-procedure]
Drift refers to the movement of an electroanatomic map during the procedure due to interference with the magnetic field. During each electrophysiology study, the principal investigator will annotate a point on the electroanatomic map with the NeuTrace System (X1). The principal investigator will then move the X-ray image intensifier (a common source of interference) to a fixed interval above the magnetic field generator and again annotate that same point on the electroanatomic map (X2). The distance between the points (X1 and X2) will be measured on the NeuTrace System in millimeters.
- Physician rating of the manual annotation of ablation points with the NeuTrace System via a questionnaire [Immediately post-procedure]
At the completion of each electrophysiology study, the principal investigator will be asked to complete a questionnaire in which he or she qualitatively rates the manual annotation of ablations points during electroanatomic mapping with the NeuTrace System on a numeric scale from 1 to 5 (1 = not satisfied, 5 = very satisfied).
- Physician rating of the total mapping time with the NeuTrace System via a questionnaire [Immediately post-procedure]
Total mapping time refers to the time taken to create an electroanatomic map. At the completion of each electrophysiology study, the principal investigator will be asked to complete a questionnaire in which he or she qualitatively rates the total mapping time with the NeuTrace System on a numeric scale from 1 to 5 (1 = not satisfied, 5 = very satisfied).
- Number of participants with serious adverse events at 30-day post-procedure telephone follow up [30 days post-procedure]
Each participant will have a telephone follow-up at 30 days post-procedure for monitoring of serious adverse events. The number of participants with a serious adverse events will be measured.
