Summary
A novel multielectrode catheter enables faster, higher-resolution electroanatomical mapping of the atria and ventricles. This technology significantly reduces procedure time compared to conventional mapping systems.
Area of Science:
- Cardiovascular electrophysiology
- Medical device technology
- Cardiac imaging
Background:
- Conventional electroanatomical mapping uses limited electrodes, resulting in lengthy procedures and low-density data.
- Multielectrode catheters offer potential for rapid, high-resolution mapping but raise concerns about maneuverability.
Purpose of the Study:
- To evaluate the feasibility of a novel multielectrode catheter for mapping the right atrium and left ventricle.
- To compare the efficiency and data density of the novel catheter against conventional systems.
Main Methods:
- Electroanatomical mapping was performed in swine using both a conventional catheter and a novel multielectrode catheter.
- Mapping was conducted in the right atrium and left ventricle under both sinus and paced rhythms.
Main Results:
- The multielectrode catheter, with continuous data collection, achieved map acquisition in 5.2–9.5 minutes with 2,753–3,566 points.
- Manual data collection with the multielectrode catheter was faster than the conventional catheter (11.4–18.1 min vs. 28.6–32.2 min).
- Conventional mapping yielded significantly fewer points (120–148) compared to the multielectrode catheter.
Conclusions:
- The novel multielectrode catheter is feasible for mapping the right atrium and left ventricle.
- This technology accelerates electroanatomical data acquisition, leading to shorter mapping times.
- Higher-density electroanatomical maps are achievable with the multielectrode catheter.
