About this study
Official title: A Silver Lining in the VAD Sky: Impact of Silver Dressing on LVAD Associated Driveline Infection
The investigators propose to conduct a prospective randomized trail (RCT) of a driveline management protocol. The study will be initiated at UCSF from January 1st 2022 to December 31st 2022 as a pilot to be extended to other sites with the ultimate goal to develop a multi-center RCT. The driveline dressing protocol studied will include a silver-based dressing barrier as well as a dressing change protocol and material designed to reduce the risk of driveline dressing induced dermatitis and allergies. Assessment will include DLI rates, DLI speciation, dermatitis rate, comfort, ease of use, compliance and cost
Read the detailed description
This prospective research clinical trial will be conducted in a single academic medical center. The enrollment period will be between January 1st, 2022 and December 31st, 2023. The initial follow-up period will be closed on December 31st 2023 with a continuation of the follow-up until December 31st 2024. Patients will be selected from current LVAD patients followed by our medical center clinic and from patients implanted with LVAD at our center during the study enrollment timeframe. Patients will be randomly assigned to the control protocol and the silver protocol. Both protocols will be taught to the patients and nursing staff by the VAD coordinators. The comparative evaluation will be done through adverse event collection, driveline culture results, patient survey and DL photos at specific intervals.
Interventions A new driveline dressing kit will be trialed on patients randomized to the intervention arm of the study. Both arms will have a regular dressing kit and a sensitive dressing kit.
The trial arm kits include:
- For standard dressing: a silverlon antimicrobial patch, CHG swabs for cleaning, an occlusive dressing with window, and driveline anchors. The driveline dressing change frequency will be weekly.
- For sensitive skin dressing: a silverlon antimicrobial patch, Providone/iodine swabs for cleaning, an occlusive dressing with window, and sensitive driveline anchors. The driveline dressing change frequency will be weekly.
The control arm kits include:
- For standard dressing: No antimicrobial barrier, CHG swabs for cleaning, an occlusive dressing with window, and driveline anchors. The driveline dressing change frequency will be every 96 hours.
- For sensitive skin dressing: No antimicrobial barrier, Providone/iodine swabs for cleaning, an occlusive dressing with window, and driveline anchors. The driveline dressing change frequency will be every 96hr.
- Being tested
- Silverlon, Control

Questions about this trial
What is this clinical trial studying?
A study testing Silverlon in people with LVAD (Left Ventricular Assist Device) Driveline Infection, run by University of California, San Francisco at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 May 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Driveline Infection Rate (time frame: 2 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05163392, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2026.
