Cardiac Resynchronization Therapy Delivery Guided Non-Invasive Electrical and Venous Anatomy Assessment

United States, Austria, Hungary150 participantsStarted 2023-03-06

Plain-language summary

The objective of this prospective, multicenter controlled study is to assess the feasibility of a patient-tailored implantation by creating a cloud-based pre-procedural multimodality CRT-roadmap by integration of 3D images from 3D activation sequence from ECG, and coronary venous anatomy from cardiac computed tomography. This CRT-roadmap will be used to guide LV lead placement to a coronary vein in an electrically late-activated region. Study Hypothesis: At least 75% of patients undergoing a CRT implantation guided by non-invasive electrical and venous anatomy assessment (XSPLINE technology) will show a reduction of left ventricular end-systolic volume of 15% or more at 6-month evaluation.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Eligible subjects shall meet all following criteria: * Appropriately signed and dated informed consent. * Age ≥18 years at time of consent. * CRT indication according to the 2021 ESC guidelines on cardiac pacing and CRT (class I and IIA indication in patients with LBBB QRS morphology) or to 2017 AHA/ACC/HFSA guidelines (COR I). * Sinus rhythm * QRS duration ≥130 ms * Left bundle branch block * Left ventricular ejection fraction ≤35% * Symptomatic heart failure NYHA class ≥ II * Documented stable medical treatment for at least 6 months * No cardiovascular intervention during the last 6 month Exclusion Criteria are: * History of persistent or permanent atrial fibrillation * Previous pacemaker or ICD implantation * Indication to pacing due to bradycardia * Patients considered for His bundle pacing or cardiac conduction pacing * Patients with unstable angina * Subject experienced a recent myocardial infarction, within 40 days prior to enrollment * Subject underwent coronary artery bypass graft or valve surgery, within 90 days prior to enrollment * Subject is post heart transplantation, or is actively listed on the transplantation list, or has reasonable probability (per investigator's discretion) of undergoing transplantation in the next year * Subject is implanted with a left ventricular assist device * Subject is on continuous or uninterrupted infusion (inotropic) therapy for heart failure * Subject has severe aortic stenosis (with a valve area of \<1.0 cm2 or significant va…

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
