Mini lead aims to supercharge heart failure therapy

NCT ID NCT03750058

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This pilot study tested a new, very small lead (under 2 French) designed to improve cardiac resynchronization therapy (CRT) for heart failure. In 20 patients getting a standard CRT device, doctors temporarily placed the new lead to see if it could pace the heart's left ventricle from multiple spots. The study measured how often the lead worked well and checked for any immediate problems.

Active substance

new micro multipolar lead (device)

What this could lead to

If successful, this could lead to a more precise and less invasive way to deliver cardiac resynchronization therapy for heart failure patients.

What could go wrong

This is a very small pilot study with only 20 patients, so results may not apply to everyone. The lead is new and could have unknown risks or fail to work as expected.
