Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients in the interventional arm will undergo implantation of pacemaker using the His-lead instead of conventional 5076 lead, via standard of care venous (subclavian or axillary) access. This procedure will be performed by electrophysiologist, and is a once off procedure (not recurring). This procedure will be performed in fully-functional cardiac catheterisation laboratory, where pacemakers are routinely inserted. The procedure takes approximately 30 minutes. The implanted pacemakers are permanent systems (lifelong), however depending on clinical circumstances an upgrade to biventricular pacemaker may be performed if a clinical indication is met.

Treatment: Devices
Comparator / control treatment
Patients in the control arm will undergo implantation of conventional 5076 lead in the right ventricle, via standard of care venous (subclavian or axillary) access. This procedure will be performed by electrophysiologist, and is a once off procedure (not recurring). This procedure will be performed in fully-functional cardiac catheterisation laboratory, where pacemakers are routinely inserted.

Active

Outcomes
Primary outcome [1] 321814 0
Composite outcome of all-cause mortality, hospitalisation rate for heart failure (HFH), left ventricular ejection fraction (LVEF), and need for upgrade to biventricular pacing systems. Specifically, mortality and hospitalisation rates will be audited through follow-up visits, assessment of left ventricular ejection function through assessment using cardiac echocardiography, and need for upgrade to biventricular pacing systems through clinical assessment of patient at each follow-up visit.
Timepoint [1] 321814 0
Outcomes will be assessed on Day 1 post-pacemaker implantation, and thereafter in month 3, 6, and 12, with a window period of 2-4 weeks, as described in the study protocol. The study is ethically approved to run for a cumulative total of 5 years, with 6-monthly visits beyond the first 12 months,
Secondary outcome [1] 376292 0
Acute His-lead dislodgement assessed by loss of function of the implanted pacemaker lead
Timepoint [1] 376292 0
30-day, 3-month, 6-month and 12-month post-pacemaker implantation. The study is ethically approved to run for a cumulative total of 5 years, with 6-monthly visits beyond the first 12 months,
Secondary outcome [2] 376293 0
Device-related wound infection assessed by local wound inspection, or presentation to hospital with infective symptoms
Timepoint [2] 376293 0
30-day, 3-month, 6-month and 12-month post-pacemaker implantation. The study is ethically approved to run for a cumulative total of 5 years, with 6-monthly visits beyond the first 12 months,
