Preventive VT Substrate Ablation in Ischemic Heart Disease
Spain58 participantsStarted 2021-06-01
Plain-language summary
The investigators hypothesize that preventive VT substrate ablation in patients with chronic ICM, previously selected based on imaging criteria (BZC mass) for their likely high arrhythmic risk, is safe and effective in preventing clinical VT events.

Inclusion Criteria:
* Age \> 18 years.
* Chronic, stable ischemic heart disease, irrespectively of the LVEF.
* Life expectancy of \> 1 year with a good functional status.
* Documented scar AND a BZC mass \> 5.15 g as measured per LGE-CMR and automatic post-processing using the ADAS-3D LV (ADAS 3D Medical SL, Barcelona, Spain).
* Signed informed consent.
Exclusion Criteria:
* Age \< 18 years.
* Pregnancy.
* Life expectancy of \< 1 year, or bad functional status (NYHA IV functional class).
* Other concomitant structural heart diseases (e.g. congenital, non-ischemic, etc.)
* Previously documented sustained ventricular arrhythmias.
* Impossibility to perform a contrast-enhanced CMR study.
* Calculated BZC mass in the scarred tissue \< 5.15 g using the ADAS-3D LV software.
* Concomitant investigation treatments.
* Medical, geographical and social factors that make study participation impractical, and inability to give written informed consent. Patient's refusal to participate in the study.
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.
