Official title
Catheter Ablation for Ventricular Tachycardia in Patients With an Implantable Cardioverter Defibrillator (CALYPSO) PILOT TRIAL
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this pilot trial is to determine the feasibility of a large, multi-center randomized clinical trial aimed to test whether a treatment strategy of percutaneous catheter ablation of ventricular tachycardia (VT) is superior to state-of-the-art pharmacologic therapy at reducing all-cause mortality in patients with an implantable cardioverter defibrillator (ICD) who receive therapy for VT in the absence of any reversible cause.
