Brief Summary
This study aims to compare antiarrhythmic drug therapy with catheter ablation using the SmartTOUCH catheter (Biosense Webster Inc.) as treatment for patients with ventricular tachycardia and coronary ...
Detailed Description
This is a multicenter, randomized prospective cohort study to compare the impact of catheter ablation with antiarrhythmic drug therapy for treating patients with sustained ventricular tachycardia (VT)...
Eligibility Criteria
Inclusion
- Sustained monomorphic VT (\>30 seconds, or requiring appropriate ICD therapy in patients with ICDs)
- Documented ischemic heart disease with no further options for revascularization
- Ability and willingness to give written informed consent to participate in the trial
Exclusion
- VT in the setting of metabolic abnormalities or acute ischemia if coronary lesions suitable for revascularization are identified.
- Acute ischemia with eligibility for revascularization
- Significant peripheral arterial disease preventing transvascular access to the left ventricle.
- Patients with arrhythmogenic right ventricular cardiomyopathy (ARVC), hypertrophic cardiomyopathy, Brugada syndrome, Long QT syndromes, dilated cardiomyopathy
- Prior long term therapy with a Class III or Class IC antiarrhythmic agent (longer than 2 weeks)
- Patient is or may be potentially pregnant
- Patient has a mechanical heart valve
- Myocardial infarction within the past 90 days
- Stroke within the past 90 days
- New York Heart Association (NYHA) functional class IV
- Hemorrhagic manifestations, bleeding diathesis, or impairment of hemostasis
- Lesions at risk of clinically significant bleeding (e.g., extensive cerebral infarction within the last 6 months, active peptic ulcer disease with recent bleeding)
- Prior VT ablation procedure
- Contraindication or allergy to contrast media, routine procedural medications or catheter materials
- Contraindications to an interventional procedure
- Life expectancy is less than 6 months
- Incessant or multiple episodes of VT requiring immediate therapy with medications or ablation
- Untreated hypothyroidism or hyperthyroidism (euthyroid or thyroid hrt is acceptable)
- Current enrolment in another investigational drug or device study
- There are other conditions present that the investigator feels would be problematic or would restrict or limit the participation for the patient for the entire study period
- Absolute contraindication to the use of heparin or warfarin
- Documented intra-arterial thrombus, ventricular thrombus, (less than 6 months after detection of thrombus), tumor or other abnormality that precludes catheter introduction
