FIRST IN HUMAN EXPERIENCE WITH SWIFT SYNC: A NOVEL ATRIO-VENTRICULAR
SEQUENTIAL TEMPORARY PACING CATHETER
Background. Current temporary transvenous pacemaker catheters
lack sequential atrioventricular (AV) pacing in synchrony. Therefore, a
catheter that could provide sequential AV pacing and maintain synchrony
may be useful for patients in sinus rhythm who need temporary pacing.
Objective. The purpose of this study was to describe the first
in human experience with a novel temporary AV sequential pacing catheter
(TAVSP). Methods. We prospectively identified eligible patients
undergoing elective cardiac catheterization in whom the TAVSP catheter
was delivered and used for temporary AV sequential pacing. Safety
endpoints and device performance data were obtained. Results.
Ten subjects were screened and enrolled in the study. TAVSP was
delivered in all ten subjects, and AV sequential synchronous pacing was
successfully obtained. The pacing catheter achieved an excellent pacing
threshold and impedance in all ten patients except for one. There were
no adverse events during the pacing procedure. Conclusion.
Temporary AV sequential pacing using TAVSP catheter is safe and feasible
and may be an alternative to conventional temporary pacing catheters to
maintain AV synchrony during temporary pacing.
