Subcostal Temporary Extracardiac Pacing Study — STEP  

Conduction Defect Clinical Trial

Official title: Subcostal Temporary Extracardiac Pacing Study: Clinical Study of the AtaCor Extracardiac Pacing System

Status Completed

Clinical Trial Summary

Up to 15 subjects will be enrolled to evaluate initial safety and performance of the AtaCor Temporary Pacing System. Safety will be evaluated through analysis of all Adverse Events. Performance will be evaluated through (1) the incidence of successful StealthTrac Lead placement using the MACH I Delivery Tool, (2) electrical performance measurements, such as pacing capture thresholds, sensed R-wave amplitudes, pacing impedance and skeletal muscle stimulation at rest. Appropriate sensing and pacing capture will be ascertained from ECG Holter Monitor recordings during periods of in-hospital ambulation.

Clinical Trial Description

Enrolled Subjects will have both a market-released transvenous pacing lead and investigational StealthTrac Temporary Pacing Lead placed and evaluated. During the placement procedure, diagnostic echocardiograms will be performed to detect any new pericardial effusions. Once inserted, the StealthTrac Lead will be used to deliver high rate pacing (160 to 220 BPM) in clinically appropriate Subjects, to demonstrate suitability for use in transcatheter procedures that require brief periods of temporary pacing. Lead positions will be documented using fluoroscopic images before the Subject leaves the procedure room. On the following two days after the procedure, electrical performance will be evaluated in multiple postures and appropriate pacing and sensing will be confirmed during activity using ECG Holter monitor recordings. Subjects will also be asked patient-centric questions about their experience with the StealthTrac Lead throughout the study period. Evaluations will continue for a minimum of two (2) and a maximum of seven (7) days after the index procedure. Prior to StealthTrac Lead removal, an X-Ray will be taken to document the final lead position and diagnostic echocardiography will be performed to (1) detect any latent pericardial effusions and (2) assess differences in cardiac function with intrinsic conduction and while pacing. A final follow-up will be performed 25-30 days after removal to identify any latent adverse events before the Subject exits the study. ;
