About the research

The VISABL-VT is a prospective, single-arm, multi-center, interventional investigation of the safety and efficacy of radiofrequency (RF) ablation of ventricular tachycardia associated with ischemic cardiomyopathy performed with the Vision-MR Ablation Catheter 2.0 in the iCMR environment.

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

Inclusion Criteria:

• Roll-in subjects only: Documentation of premature ventricular contractions indicated for ablation therapy (subjects may or may not be diagnosed with Ischemic Cardiomyopathy)
• Documented (ECG/EGM) spontaneous episode of sustained ventricular tachycardia within 6 months of the procedure
• Diagnosis of Ischemic Cardiomyopathy
• AAD therapy refractory, contraindicated, not tolerated, or not desired
• 18 years or older

Exclusion Criteria:

• Implanted with non-MR compatible medical devices or contraindicated for an MRI
• Presence of intracardiac thrombus (verified via CT/MRI/TEE/TTE within 48 hours of procedure - or at start of procedure)
• Thrombocytopenia or coagulopathy
• Mechanical mitral and/or aortic valve precluding access to the left ventricle
• Severe aortic stenosis
• Myocardial infarction requiring stent implantation within 90 days of procedure
• Previous cardiac surgery within 60 days of procedures
• Known/uncontrolled stroke risks
• Class IV Heart Failure
• Ejection Fraction (EF) \< 25%
• Patients with a glomerular filtration rate (GFR) \< 30
• Women who are pregnant
• Allergy to contrast agents (e.g., Gadolinium)
• Active infection
• Known or suspected myxoma
• Unstable angina
• Patients who do not tolerate anticoagulation therapy
• Previous intertribal septal patch or prosthetic atrial septal defect closure device
• Life expectancy \< 12 months
• Enrollment in another study without sponsor approval

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.
