Official title Preventive Catheter Ablation for Ventricular arrhythmiaS in Patients With End-sTage Heart faiLure
ClinicalTrials.gov ID: NCT06556485
What this study is testing
What is Medical therapy?
Medical therapy is an investigational medicine, being studied as a potential treatment for heart failure.
Also referred to as Medical.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- CASTLE-VT is a randomized evaluation of prophylactic ablative treatment of arrhythmogenic ventricular scar in patients referred for HTx evaluation and diagnosed with ICM. Ablation will be performed with the use of a substrate-based approach in which the myocardial scar is mapped and ablated while the heart remains predominantly in sinus rhythm.
