Study Design

Observational model cohort
Time perspective prospective
Patients who have received any market approved St Jude Medical CRT-D or CRT-P device
crt patients St Jude Medical, Any approved CRT device
This is a group of patients who are receiving bi-ventricular pacing therapy from CRT device.

Primary Outcomes

Rates of non-responders to CRT using 1) clinical composite score and 2) site-specific criteria for determining response to CRT
time frame: 6 months
Characterizing the types of symptom-based and objective definitions used by sites to determine patients' response to CRT
time frame: 6 months
Characterizing the treatment strategies employed by sites to treat HF in the non-responder population
time frame: 12 months
Efficacy of treatment strategies used to treat non-responders as determined by the rate of response in non-responders to CRT
time frame: 12 months

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Patient willing and able to sign informed consent - Patients implanted with any market-approved St. Jude Medical CRT-D/P device with no prior LV lead placement Exclusion Criteria: - Are likely to undergo heart transplantation within the next 12 months - Are less than 18 years of age - Are pregnant or planning to become pregnant during the duration of the study - Are currently participating in a clinical investigation that includes an active treatment arm - Have a life expectancy of less than 6 months

Additional Information

Official title Registry That Aims to Understand the Definition Used and Treatment Options Utilized by Clinicials for CRT Non-responders
Description Patients who are implanted CRT devices will be enrolled in the study. Once implanted, all patients will be followed at every 3 months for the first 12 months from the implant. The responder/non-responder evaluation will occur at 6 months from the implant date. The criteria used for determining the response to CRT will be captured. During the office follow-up visits, arrhythmic episode diagnoses, device data and stored electrogram will be collected. All clinical events such as hospitalization for HF, all-cause hospitalizations, and all-cause death will also be collected. For patients who are non-responders to CRT, any re-optimization of the device, i.e., AV/VV interval optimization, LV lead repositioning and pacing vector reconfiguration as well as modified/new clinical therapies administered in an attempt to improve HF condition will be collected.
