Plain-language summary
Certain patients with congestive heart failure are treated both by implantation of an LVAD, as well as implantation with a biventricular pacemaker. Both of these devices, individually, have been shown to improve the health of patients with heart failure. However, only a small number of patients have both an LVAD and a biventricular pacemaker at the same time.
Pacemakers have many different settings. However, there is little data to inform physicians which of these different settings is best for the flow of an LVAD. This study is evaluating patients who have both a biventricular pacemaker and an LVAD. Investigators will operate the pacemaker at multiple different settings and monitor the LVAD's function to determine which, if any, setting is best for the LVAD's flow.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* All patients who have undergone implantation of both a biventricular pacemaker and LVAD who are at least three months post-LVAD implantation and who receive routine follow-up care at the UC Davis / UC San Diego Adult Arrhythmia/ Device/ LVAD clinic.
* Potential enrollees have been directly identified by their existing medical providers in clinic, who are investigators in this study.
Exclusion Criteria:
* Any patients who do not present to their routine follow-up appointment at the time of this study.
* Any patients who have undergone LVAD placement less than three months prior to enrollment.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
