Trial Summary

What is the purpose of this trial?

This trial aims to improve heart device placement using a personalized plan created from advanced 3D images. It targets patients who need precise heart treatment. The detailed images help doctors place the device in the best spot to improve heart function. This therapy has emerged as an established treatment for patients with severe heart conditions and symptoms that do not respond to standard medication.

Will I have to stop taking my current medications?

The trial requires that participants have been on stable medical treatment for at least 6 months, so you will not need to stop your current medications if they have been stable.

What data supports the effectiveness of the treatment XSpline, CRT, CRT-P, CRT-D, Biventricular Pacemaker, Cardiac Resynchronization Device for chronic heart failure?

Research shows that cardiac resynchronization therapy (CRT) can improve symptoms and survival in patients with heart failure and specific heart rhythm issues. Studies also highlight the importance of choosing between a CRT pacemaker (CRT-P) and a CRT with defibrillator (CRT-D) based on individual patient needs, as both have shown benefits in managing heart failure. ^{1 2 3 4 5}

Is guided CRT implantation generally safe for humans?

Implanting cardiac resynchronization devices like CRT-P and CRT-D is generally safe, but there are rare complications that can occur during the procedure. Studies have shown that these devices are used to manage heart failure, and while they can reduce hospital readmissions, there are some risks involved with the implantation process. ^{2 6 7 8 9}

How is the Guided CRT Implantation treatment for chronic heart failure different from other treatments?

Guided CRT Implantation is unique because it uses advanced techniques like electromagnetic navigation and 3-D mapping to precisely place the device, reducing x-ray exposure and targeting the most delayed heart regions for optimal response. This approach aims to improve the effectiveness of the treatment compared to traditional methods. ^{1 2 5 6 10}

Treatment Details

Interventions

• XSpline (Device)

Trial Overview The study tests if guiding CRT implantation using XSpline—a non-invasive method combining ECG and CT imaging to create a detailed roadmap—improves outcomes. The goal is that patients will show significant improvement in the size of their left ventricle after six months compared to standard placement methods.

Participant Groups

Group I: CRT implantation guided by XSpline Experimental Treatment 1 Intervention

The sample size estimation was based on two recent studies including CRT patients with similar clinical and demographic characteristics as in this study: the SMART-MSP and the SMART CRT. The SMART-MSP is a prospective, observational study that enrolled 584 CRT recipients at 52 US sites. In a typical modern CRT population, 75% of patients had a reduction of the end-systolic volume ≥ 15% at 6-month follow-up. The SMART-CRT study enrolled 699 CRT patients randomized to a treatment arm and a control group. At 6-months follow-up, a reduction of LVESV ≥15% was achieved for 67.7% of the patients in the control group and for 74.8% of those in the treatment arm. Therefore, it is assumed that in a modern CRT population at least 70% of the patients will have a reduction of the LVESV ≥15% of the baseline value at 6-months after CRT implantation. To demonstrate that this proportion of patients can be equally achieved with the approach tested in this study at least 150 patients need to be included.

Findings from Research

The use of cardiac resynchronization therapy (CRT) devices, including CRT-P and CRT-D, has significantly increased due to better operator experience and expanded patient eligibility.

In a specific case, innovative device programming successfully achieved effective biventricular pacing despite challenges with repeated dislodgement of the atrial lead, highlighting advancements in CRT technology.

Use of a novel pacing mode to achieve biventricular pacing in a patient with recurrent atrial lead dislodgement after CRT-D implantation. Devidutta, S., Sridevi, C., Narasimhan, C.[2020]

In a study of 84 heart failure patients with biventricular pacemakers (CRT-P), 13.1% experienced unsustained ventricular tachyarrhythmias during an average follow-up of 29 months, indicating that while CRT-P can be tolerated, there is still a risk of arrhythmias.

The upgrade to a CRT-D (with a defibrillator) did not significantly prevent sudden death, as evidenced by one patient who died suddenly 15 months after the upgrade, suggesting that CRT-P may be a viable option for certain patients without an ICD.

In a study of 151 patients who received complex cardiac devices (ICD, CRT-P, CRT-D) over two years, the overall procedural success rate was an impressive 99.3%, indicating high efficacy in implantation.

Complications occurred in 9.3% of cases, with lead displacement being the most common issue (5.3%), but there were no procedure-related deaths, highlighting the safety of these procedures when performed by experienced clinicians.

In a study of 60 patients with chronic heart failure, those who received implantable cardioverter defibrillator/cardiac resynchronization therapy defibrillator (ICD/CRT-D) showed a significantly lower readmission rate for heart failure (30.0%) compared to the control group (56.67%), indicating improved management of heart failure with remote monitoring.

The ICD/CRT-D group also experienced a much faster diagnosis time for ventricular tachycardia/ventricular events (2.55 days) compared to the control group (37.32 days), allowing for quicker medical intervention and potentially better patient outcomes.

In a study of 360 heart failure patients with significant right ventricular pacing, upgrading to cardiac resynchronization therapy with defibrillator (CRT-D) significantly reduced the risk of all-cause mortality and heart failure hospitalization compared to standard ICD therapy, with only 32.4% experiencing adverse outcomes in the CRT-D group versus 78.9% in the ICD group.

The safety profile was similar between CRT-D and ICD groups, with comparable rates of procedure-related complications, indicating that CRT-D is a safer and more effective option for patients with heart failure and high right ventricular pacing burden.

Upgrade of right ventricular pacing to cardiac resynchronization therapy in heart failure: a randomized trial. Merkely, B., Hatala, R., Wranicz, JK., et al.[2023]

From 2003 to 2013, approximately 439,010 cardiac resynchronization therapy (CRT) devices were implanted in the U.S., with a complication rate of 6.1%, indicating that while CRT is generally safe, some patients do experience complications.

The study found that the severity of comorbid conditions among patients increased over the years, leading to a higher rate of complications during CRT procedures, particularly in older patients and females, although in-hospital mortality and length of stay did not show significant changes.

The combination of electromagnetic navigation and electroanatomical mapping systems significantly reduces x-ray exposure during the implantation of cardiac resynchronization therapy (CRT) devices.

This technique allows for more precise targeting of delayed activation regions in the heart, which can enhance the effectiveness of CRT by avoiding scar tissue and improving patient outcomes.
