What is the purpose of this trial?

This trial aims to determine if a small heart monitor, the Medtronic LINQ-2 Insertable Cardiac Monitor (ILR), can detect irregular heart rhythms, such as atrial fibrillation, in individuals starting a specific cancer treatment called Bruton Tyrosine Kinase inhibitors. The trial tracks the frequency of these heart issues and the actions taken in response. Candidates may qualify if they are beginning this cancer treatment, have no history of certain heart problems, and are open to using a device for heart monitoring. As an unphased trial, this study provides a unique opportunity to contribute to research that could enhance heart monitoring for cancer patients.

Will I have to stop taking my current medications?

The trial requires that you are not currently taking any anti-arrhythmic or anticoagulant medications. If you are on these medications, you would need to stop them to participate.

What prior data suggests that the Medtronic LINQ-2 insertable cardiac monitor is safe for arrhythmia detection?

Research has shown that the Medtronic LINQ-2 insertable cardiac monitor (ICM) is generally well-tolerated. This small device is placed under the skin to monitor heart rhythms over an extended period. Studies have found it can track heart activity for up to three years without issues.

Most people do not experience serious side effects from the device implantation. Some common, mild side effects may include minor skin reactions or discomfort at the insertion site, but these usually resolve on their own.

The LINQ-2 is already approved and used in hospitals for heart monitoring, indicating it is considered safe. Overall, the LINQ-2 ICM is a reliable tool for tracking heart rhythms, with minimal risk of serious complications. ^{1 2 3 4 5}

Why are researchers excited about this trial?

While most arrhythmia detection methods rely on external devices or short-term monitoring, the Medtronic LINQ-2 Insertable Cardiac Monitor offers a unique approach by being implanted under the skin for continuous, long-term monitoring. This allows for more accurate and comprehensive detection of irregular heart rhythms over extended periods. Researchers are excited about this device because it provides real-time data without interrupting daily activities, potentially leading to earlier and more precise diagnosis of arrhythmias. Unlike traditional methods that may miss sporadic episodes, the LINQ-2's continuous monitoring could significantly improve patient outcomes.

What evidence suggests that the Medtronic LINQ-2 insertable cardiac monitor is effective for arrhythmia detection?

Research has shown that the Medtronic LINQ-2 Insertable Cardiac Monitor (ICM) effectively monitors the heart over the long term. It detects irregular heartbeats, such as atrial fibrillation, by tracking heart rhythms over time. Studies have found that these monitors are cost-effective and improve diagnosis in patients with unexplained symptoms. In this trial, patients who begin treatment with Bruton tyrosine kinase inhibitors will consent to the installation of the LINQ-2 device for monitoring. The LINQ-2 uses advanced AI technology to collect accurate information about heart activity. This data helps doctors better understand heart conditions and make informed treatment decisions. ^{1 3 6 7 8}

Insertable loop recorders (ILRs) are generally safe devices used for continuous cardiac monitoring, but rare complications can occur, such as the subacute rupture of breast implants after placement.

This case report is the first documented instance of breast implant rupture following ILR insertion, highlighting the need for awareness of potential complications associated with this procedure.

Implantable loop recorders are effective diagnostic tools for detecting cardiac arrhythmias without relying on patient compliance, making them a reliable option for continuous monitoring.

These devices use automatic algorithms to preselect arrhythmic events, which are then transmitted via telemonitoring to cardiac specialists, enhancing the efficiency of diagnosis and management.

The BioMonitor 2-AF, an implantable loop recorder, demonstrated high P-wave visibility (94.4%) and effective remote monitoring with 100% successful automatic transmissions, indicating its reliability for continuous cardiac monitoring.

No complications related to the ILR were reported, and while some misclassification of episodes occurred in 15.8% of patients, the overall safety and effectiveness of the device were confirmed in this first-in-human study involving 19 patients over a 6-week follow-up.

The Medtronic Reveal LINQTM implantable loop recorder (ILR) was successfully used in 154 patients, allowing for remote monitoring and leading to earlier diagnosis of serious arrhythmias in 64% of cases during an average follow-up of 12.1 months.

While the device was generally safe, with only one case of skin erosion and no infections, there were notable issues with false bradycardia detection in 29% of patients due to undersensing, highlighting a technical challenge that needs to be addressed.

In a study of 181 patients with unexplained syncope, presyncope, or palpitations, the implantable loop recorder (ILR) was able to provide a diagnostic result in 54.1% of cases, confirming its value in identifying cardiac arrhythmias.

The average time to a diagnostic event was about 11 months, and the ILR was particularly effective for patients with syncope or presyncope, suggesting it should be considered early in the evaluation process for these symptoms.
