Abstract

ADVANCE III Trial.

Introduction:

The purpose of this investigation is to evaluate whether a prolonged detection interval for life threatening ventricular tachyarrhythmia (VT) is able to reduce therapies (Rx) delivered by an implantable cardioverter/defibrillator (ICD). Until now, only the PREPARE trial demonstrated a reduction of ICD Rx in a cohort of primary prevention patients.

Methods and Results:

The ADVANCE III study is a prospective, randomized, parallel trial with 2 arms evaluating different intervals to detect (NID), i.e., 18/24 (as currently used) versus 30/40. The primary endpoint is to demonstrate a 20% reduction of ICD Rx (antitachycardia pacing or shocks) delivered to terminate spontaneous VT with a cycle length ≤320 ms in patients with Class I-IIA indication for ICD therapy, regardless of cardiac resynchronization capabilities. The worldwide investigation started in spring 2008 and is expected to be finished in 2011.

Conclusions:

The ADVANCE III trial is the first randomized investigation evaluating the reduction of ICD Rx for fast VT due to a prolongation of NID in a general ICD patient cohort.(J Cardiovasc Electrophysiol, Vol. 20, pp. 663–666, June 2009)
