Clinical Scorecard: Heartbeat-powered pacemaker may pave way for self-sustaining devices
At a Glance
Category Detail
Condition Leadless intracardiac pacemaker Key Mechanisms Energy harvested from cardiac motion using triboelectric nanogenerators (TENG) Target Population Adult swine (preclinical study) Care Setting Preclinical evaluation of device implantation
Key Highlights
Self-sustaining leadless pacemaker generates electricity from heartbeats. Device achieved stable pacing with increased heart rates in swine. Power density of the device was over 100% higher than previously reported implanted nanogenerators. No thrombus formation or significant adverse effects observed during chronic evaluation. Further studies needed to assess long-term safety and performance. Guideline-Based Recommendations
Diagnosis
Management
Monitoring & Follow-up
Risks
Localized fibrosis and tissue reaction observed around fixation site. Need for longer implantation studies to assess tissue remodeling and safety. Patient & Prescribing Data
Not applicable (preclinical study in swine)
Device designed for implantation using standard catheter methods.
Clinical Best Practices
Evaluate long-term performance and safety in larger animal cohorts. Consider the need for a compact storage component for energy regulation. Related Resources & Content
