研究概览
简要总结
Up to 12 subjects will be enrolled (up to 8 undergoing an AtaCor Temporary Pacing System procedure) in order to evaluate initial safety and performance of the AtaCor Temporary Pacing System when used with three (3) strategies for stabilizing AtaCor Temporary Pacing System electrical measurements over a two (2) to seven (7) day period. The three treatments are (1) Negative Pressure Wound Therapy, (2) Anti-Inflammatory Glucocorticoid and (3) increased electrode spacing. A control arm with no additional treatment is also included. 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. Appropriate sensing and pacing capture will be ascertained from ECG Holter Monitor recordings during periods of in-hospital ambulation.
详细描述
Enrolled Subjects will have both a market-released transvenous pacing lead and investigational StealthTrac Temporary Pacing Lead placed and evaluated. Following StealthTrac Lead insertion, each subject will receive (1) one of three (3) study treatments intended to stabilize pacing capture thresholds and pacing impedance over time or receive no treatment. The three treatments are (1) Negative Pressure Wound Therapy, (2) Anti-Inflammatory Glucocorticoid and (3) increased electrode spacing achieved by the use of two inserted StealthTrac Leads. 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 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. A final follow-up will be performed 25-30 days after removal to identify any latent adverse events before the Subject exits the study.
