N/A

Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Structural heart disease: ischemic or non-ischemic cardiomyopathy diagnosed with cardiac imaging demonstrating either segmental myocardial dysfunction, or presence of scar
Must not have
Active ischemia (acute thrombus diagnosed by coronary angiography, or dynamic ST segment changes demonstrated on ECG) or another reversible cause of VT (e.g. drug-induced arrhythmia), had recent acute coronary syndrome within 30 days thought to be due to acute coronary arterial thrombosis, or have CCS functional class IV angina. Note that biomarker level elevation alone after ventricular arrhythmias does not denote acute coronary syndrome or active ischemia.
Inotrope-dependent heart failure or an anticipated life-expectancy of < 1 year in the absence of VT
Timeline
Screening 3 weeks
Treatment Varies
Follow Up through study completion,min of 7.5 months to max of 2 years
Awards & highlights

Summary

This trial is testing the use of SBRT to see if it can help people with VT that has not been helped by other treatments.

Who is the study for?
This trial is for people with heart conditions like a heart attack or ventricular tachycardia, who've tried other treatments without success. They must have had specific types of VT events despite medication and possibly catheter ablation. Pregnant individuals, those with life expectancy under one year (excluding VT), recent acute coronary syndrome, or prior radiotherapy in the treatment area cannot join.Check my eligibility
What is being tested?
The study tests Stereotactic Body Radiotherapy (SBRT) as a non-invasive option to target and treat areas of the heart responsible for causing dangerous rapid heartbeats known as ventricular tachycardia (VT). It aims to provide an alternative when standard therapies like drugs or invasive procedures fail.See study design
What are the potential side effects?
Potential side effects may include damage to nearby organs due to radiation exposure, skin reactions similar to sunburns, fatigue after treatment sessions, and rare cases of secondary cancers from long-term radiation effects.
