Study type
Interventional
Description of intervention(s) / exposure
The study is aimed at demonstrating that frequent AV/PV and V-V delay optimisation using QuickOpt in patients with Cardiac Resynchronisation Therapy Defibrillation devices results in improved clinical response over standard of care (i.e. empiric programming or one-time optimisation using any non-intracardiac electrogram optimisation methods). SJM has developed inter-ventricular (V-V) delay optimisation to synchronize the electrical activation of the conducted intrinsic and paced wavefronts between the pacing electrodes. The Atrio-ventricular (AV/PV) optimisation method characterises the inter-atrial conduction patterns in order to maximise preload and allow for proper timing of mitral valve closure. The intervention is observed for a period of 12 months, from which time the device will remain implanted.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients must meet indications to be implanted with a SJM CRT-D device with V-V timing and compatible lead system. The CRT-D must be switched ON prior to performing any baseline measurements at enrollment. Patients must be enrolled withing two weeks post CRT-D implant.
Randomisation will be blocked by investigational sitet and stratified by the patients cardiomyopathy classification of ischemic or non-ischemic. In order to do so sealed opaque envelopes will be used for the randomisation process
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Neither the patient nor the physician/nursing staff performing the HF assessment will be aware of the randomisation assignement. Heart Failure Clinical composite Assessement CRF is completed by and signed by a blinded rater only. Randomisation will be done via stratification based upon the patients cardiomyopathy classification of: ischemic or on-ischemic.
Masking / blinding
