Summary

This trial is testing a special setting in heart devices called SyncAV ON to help patients with new heart devices. It aims to improve how well their hearts pump blood by adjusting the timing of electrical signals in the heart.

Who is the study for?
This trial is for adults with heart failure who have a specific ECG pattern, intact AV conduction, and are on optimal heart failure medication. They must be getting a new CRT device or upgrading to an Abbott CRT system without prior LV lead placement. Exclusions include recent heart issues, stroke, certain procedures within the last few months, persistent AF, pregnancy, limited life expectancy or other conflicting clinical trials.
What is being tested?
The SyncAV Post-Market Trial tests if setting CRT devices to 'SyncAV ON' improves heart function better than traditional fixed AV delay settings by observing changes in the left ventricle's size and function over time.
What are the potential side effects?
While not explicitly listed here, side effects may include typical risks associated with CRT device implantation such as infection at the site of surgery, bleeding complications or issues related to improper pacing like dizziness or palpitations.

Other Research
Common treatments for Congestive Heart Failure (CHF) include pharmacologic therapies such as beta-blockers, ACE inhibitors, and ARBs, which help reduce the heart's workload and prevent further damage. Cardiac resynchronization therapy (CRT) devices, particularly those with SyncAV ON programming, optimize the timing of electrical impulses to improve heart muscle synchronization and enhance left ventricular (LV) reverse remodeling. This improved synchronization is vital for CHF patients as it enhances cardiac efficiency, reduces symptoms, and improves overall heart function and quality of life.
