Device Replacement Clinical Trial
Official title:
BIOtronik Study to Assess the CONTINUation of Existing Risk of Ventricular Arrhythmias After CRT-D Replacement for Patients With Primary Prevention Indication
Cardiac resynchronization therapy (CRT) has been shown to reduce heart failure (HF),
hospitalizations and death in patients with left ventricular ejection fraction (LVEF) <35%
and wide QRS. CRT provides electromechanical resynchronization and improves LV systolic
function. The induced LV reverse remodeling or near normalization in LVEF to ≥45% is
associated with a significant reduction in the risk of subsequent life-threatening
ventricular tachyarrhythmias (VTA). And at the time of replacement, the need for
defibrillator back-up after an event-free first CRT-D service-life for patients with improved
LVEF is a controversy question.
80% of Implantable Cardioverter Defibrillator (ICD) patients implanted for primary prevention
do not experience VTA during the life-time of their first device.
So, regarding patients implanted with a CRT-D for primary prevention at the time of first
implantation, the question is will they experience VTA after their device replacement by
another CRT-D.
The objective of this study is to describe, in a population of patients who had a primary
prevention ICD indication at first implantation of a CRT-D, the relevance defibrillator
back-up after the replacement of the first CRT-D. For that, the rate of patients with at
least one sustained VTA detected by the CRT-D or a conventional surface ECG will be assessed
after the device replacement.
Furthermore, the association between the baseline characteristics of the CRT-D population
after replacement and the risk of subsequent VTA will be explored after a minimum of two
years FU.
