LBBAP vs BiV Pacing for Heart Failure
(RAFT-P&A Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores two methods to assist people with heart failure and atrial fibrillation, a type of irregular heart rhythm. One group will receive a treatment called BiV pacing, while another will try LBBAP (Left Bundle Branch Area Pacing). Both groups will undergo AV node ablation to help manage heart rhythm. This trial suits individuals who have not found success with other heart treatments and are considering AV node ablation. As an unphased trial, it provides a unique opportunity to explore innovative treatments for heart rhythm management.
Will I have to stop taking my current medications?
The trial information does not specify if you need to stop taking your current medications. However, it mentions that participants should be on optimal heart failure therapies for at least 4 weeks, which suggests you may need to continue your current heart failure treatments.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that Left Bundle Branch Area Pacing (LBBAP) is generally safe and well-tolerated. Studies indicate it achieves high success rates and maintains acceptable complication rates, even when performed by less experienced doctors. This treatment often addresses conditions like a slow heart rate and heart failure.
For Cardiac Resynchronization Therapy (CRT), research has found it effective in reducing the risk of heart failure events. It also lowers the chances of death and hospital readmissions compared to medication alone. However, about 30% of patients may not experience improvements with CRT.
Both treatments have demonstrated promising safety records, although individual responses can vary. Always consult a healthcare provider to understand what these findings mean for personal health decisions.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for heart failure because they offer unique approaches to improving heart function. Unlike traditional Cardiac Resynchronization Therapy (CRT), which uses a combination of electrical pacing and AV node ablation to synchronize the heart's ventricles, Left Bundle Branch Area Pacing (LBBAP) targets the heart's conduction system more naturally. This method aims to mimic the heart's normal electrical pathway, potentially leading to better heart performance and fewer complications. By refining the way electrical impulses are delivered, LBBAP could offer a more efficient and effective option for patients with heart failure.
What evidence suggests that this trial's treatments could be effective for heart failure?
Research has shown that Left Bundle Branch Area Pacing (LBBAP), which participants in this trial may receive, is a promising treatment for heart failure. Studies have found that LBBAP can help manage heart rhythms and improve heart function, especially for patients who do not benefit from traditional treatments like cardiac resynchronization therapy (CRT). In this trial, one group will receive LBBAP followed by AV node ablation, while another group will receive CRT followed by AV node ablation. LBBAP is widely used due to its high success rates and acceptable safety. Clinical findings indicate that LBBAP can be a reliable option for people with heart failure, with positive results reported in various trials. These studies suggest that LBBAP could be a strong alternative for heart failure patients who need pacing treatments.678910

Are You a Good Fit for This Trial?
This trial is for heart failure patients with atrial fibrillation who can't use rhythm control and are on stable heart failure medication. It's also for those who've had a failed ablation, can't tolerate certain drugs, or choose not to have rhythm control strategies. People with recent severe cardiac events, certain types of cardiomyopathy, severe lung disease, or life expectancy less than one year due to non-cardiac causes cannot join.Inclusion Criteria
