Could a simpler heart device be just as effective?

NCT ID NCT03587064

First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time

Summary

This trial tests whether a newer, simpler 2-lead cardiac resynchronization therapy defibrillator (CRT-DX) works as well as the standard 3-lead system (CRT-D) in people with heart failure. The study includes 640 adults who need a CRT-D and have a normal heart rhythm. The main goal is to compare rates of death, heart-related hospital stays, and lead complications between the two devices.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
2-lead CRT defibrillator system (CRT-DX)
What this could lead to
If successful, this could show that a simpler, 2-lead defibrillator works as well as the standard 3-lead version, potentially making implantation easier and reducing complications.
What could go wrong
This is a non-inferiority trial, meaning it aims to prove the simpler device is not worse, not that it is better. The results may not apply to all heart failure patients, and there is always a risk of device-related complications.
