BERLIN VT Studie - Vorsorgliche Ablation von Kammertachykardien in Patienten mit Herzinfarkt

Procedure: VT ablation

Inclusion Criteria:

1. History of remote myocardial infarction

2. Left ventricular ejection fraction = 30 to = 50 % as estimated by cardiac MRI,
3D-echocardiography or via ventriculography within 30 days before enrollment

3. Documentation of sustained ventricular tachycardia (VT) by any kind of
Electrocardiography (ECG) including 12 lead ECG, holter ECG, rhythm strip, event
monitoring, event recorder or pacemaker within 30 days before enrollment

4. Implantable cardioverter-defibrillator (ICD) indication for secondary prevention

5. Patients who are planned to be implanted with BIOTRONIK ICDs (single, dual, triple
chamber or DX device)

6. Patient has provided written informed consent

7. Patient accepts activation of Home Monitoring®

Exclusion Criteria:

1. Age < 18 years or > 80 years

2. Known arterial or venous thrombosis

3. Class IV New York Heart Association (NYHA) heart failure

4. Valvular heart disease or mechanical heart valve precluding access to the left
ventricle

5. Acute myocardial reinfarction or acute coronary syndrome

6. Cardiac surgery involving cardiotomy within the past 2 months

7. Patients requiring chronic renal dialysis

8. Thrombocytopenia or coagulopathy

9. Incessant VT or electrical storm

10. Bundle branch reentry tachycardia as the presenting VT

11. Pre-existing implantable cardioverter-defibrillator (ICD)

12. Pregnancy or breast feeding women

13. Acute illness or active systemic infection

14. Other disease process likely to limit survival to less than 12 months

15. Significant medical problem that in the opinion of the principal investigator would
preclude enrollment in the study

16. Unwillingness to participate or lack of availability for follow-up

17. Participation in another interventional clinical investigation during the course of
the study, i.e. the participation in a non-interventional clinical investigation is
allowed.
