Observational Study Comparing Leadless Pacemakers and Left Bundle Branch Area Pacing
Summary
NIH registered clinical trial NCT07534917, an observational acute study comparing leadless right ventricular pacemakers and temporary left bundle branch area pacing on cardiac function and tricuspid valve. Both procedures conducted in one sitting under general anesthesia. Participants referred for routine pacemaker implantation may enroll. The study aims to guide pacemaker type selection for patients at risk of valve or heart dysfunction.
What changed
NIH registered a new observational clinical trial (NCT07534917) on ClinicalTrials.gov studying the acute effects of two newer pacemaker technologies on cardiac function and tricuspid valve performance. The study compares leadless right ventricular pacemakers against left bundle branch area pacing in patients referred for routine pacemaker implantation.
For cardiac device manufacturers and healthcare providers, this study represents ongoing research into emerging pacing technologies that may influence future device selection and clinical practice guidelines. Compliance officers should note this is a research registration without immediate regulatory implications, but outcomes may inform future guidance on pacemaker choice in patients at risk for tricuspid valve or cardiac dysfunction.

Comparing the Effects of Newer Pacemakers and Their Effects on the Heart and Valve Function in the Short-term.
Observational NCT07534917 Kind: OBSERVATIONAL Apr 16, 2026
Abstract
Conventional pacemakers involve placing a lead through a valve into the bottom right chamber of the heart. Research has shown that this is associated with an increased risk of valve dysfunction and mortality as well as impairment of heart function.Newer pacemakers such as leadless pacemakers and pacemakers that engage directly with the heart's native conduction system (known as left bundle branch pacemakers), are increasingly being adopted. However, the impact of these newer pacing technologies on the heart and tricuspid valve, as well as how they compare against each other, is unclear.
We aim to study the impact of leadless pacemakers and left bundle branch pacemakers on cardiac function and tricuspid valve by conducting an acute study that will be performed in addition to the routine pacemaker implantation that the participant has been referred for. Both procedures will be performed in one sitting under general anaesthesia. Outcomes from this study will improve our understanding of how these pacing technologies affect heart and valve function and how they compare against each other. This will guide decision-making regarding the ideal type of pacemaker to be adopted, especially in patients who stand to suffer the most from developing tricuspid valve or heart dysfunction.
