FULCRUM-VT Trial Summary
This trial will study the safety and effectiveness of a new device to treat a type of abnormal heart rhythm.
Who is the study for?
This trial is for adults (18+) with recurrent, symptomatic ventricular tachycardia linked to heart disease who've had an ICD implanted and are unresponsive or intolerant to certain medications. Participants must have a left ventricular ejection fraction of at least 20% and have experienced VT in the past 6 months. Exclusions include allergies to contrast dye, recent heart procedures, pregnancy, other conflicting medical conditions or treatments.Check my eligibility
What is being tested?
The study tests the safety and effectiveness of the Adagio VT Cryoablation System for treating Sustained Monomorphic Ventricular Tachycardia (SMVT). It involves using cold temperatures to destroy abnormal heart tissue causing rapid heartbeat.See study design
What are the potential side effects?
Potential side effects may include discomfort at the ablation site, bleeding, blood vessel damage, arrhythmias during procedure recovery, reactions to contrast dye used during imaging if not managed properly.

Study Objectives
Outcome measures can provide a clearer picture of what you can expect from a treatment.Primary outcome measures
Primary Endpoint for Safety - Analysis of the proportion of subjects with freedom from definite or probable device/procedure related Major Adverse Events (MAEs) that occur within 7 days following the cryoablation procedure.
Primary Procedural Endpoint - Analysis of the proportion of subjects with non-inducible VT or no further ablation targets meeting the criteria for ablation at the end of the cryoablation procedure.
Secondary outcome measures
Secondary Efficacy Endpoint - Analysis of the proportion of subjects with freedom from VT > 30 seconds
Secondary Efficacy Endpoint - Analysis of the proportion of subjects with freedom from VT > 30 seconds without AAD
Secondary Efficacy Endpoint - Analysis of the proportion of subjects with freedom from inducible MMVT <30s

Are there any remaining vacancies in this trial available for participants?
"According to the information listed on clinicaltrials.gov, this research is no longer enrolling participants as it was last amended in early January of 2023. Nonetheless, 123 other medical studies are currently searching for individuals that would like to take part in a trial."
Answered by AI
What aims has this research project set out to accomplish?
"This study is primarily assessing the rate of freedom from definite or probable device/procedure related Major Adverse Events (MAEs) within a 7-day period post-cryoablation. Secondary objectives evaluate Freedom from inducible MMVT with a cycle length similar to (within 30 ms) or slower than the targeted VT and lasting longer than 30 seconds at procedure's end, as well as Freedom from Ventricular Tachycardia lasting longer than 30 seconds without AADs."
