Outcome Measures
Primary Outcomes (1)
Number of Vectors With Phrenic Nerve Stimulation (PNS)
The primary objective of this study was to characterize the performance of Boston Scientific (BSC) unique pacing vectors vs. BSC/St Jude Medical (STJ) common pacing vectors to prevent phrenic nerve stimulation (PNS) based on the selected pacing cathode. BSC unique vectors are those that are only available with Boston Scientific's (BSC) quadripolar (X4) CRT-Ds while common vectors are those that are available for both BSC and STJ systems.
Pre-discharge (up to 7 days post implant)
Secondary Outcomes (4)
Final Pacing Treshold at Pre-discharge
Pre-discharge (up to 7 days post implant)
Final LV Lead Impedance at Pre-discharge
Pre-discharge (up to 7 days post implant)
Final Sensing Amplitude at Pre-discharge
Pre-discharge (up to 7 days post implant)
Delivery System Comparison Between ACUITY Pro and the Other Delivery Systems
At time of implantation (0 to 30 days post consent signature)
Study Arms (1)
All study patients
All study patients will be implanted with a Boston Scientific (BSC) quadripolar Cardiac Resynchronization Therapy (CRT-D) and a currently approved quadripolar left ventricular lead. At the pre-discharge visit, multiple vectors will be tested in order to assess their respective performance.
Eligibility Criteria
Subjects will be selected from the center's general population who are indicated for a CRT-D. All study subjects will be implanted with the BSC DYNAGEN or INOGEN X4 CRT-D (or any future FDA approved BSC X4 CRT-D). Subjects may have a previously implanted/will be receiving an approved quadripolar left ventricular lead.
You may qualify if:
- Subject is medically indicated for implantation with a Boston Scientific (BSC) DYNAGEN or INOGEN X4 CRT-D (or any future FDA approved BSC X4 CRT-D) and already implanted with/scheduled to receive a commercially available quadripolar left ventricular lead
- Subject is willing and capable of providing informed consent and participating in all testing and study visits associated with this investigation at an approved center and at the intervals defined by this protocol
- Subject is age 18 or above, or of legal age to give informed consent specific to state and national law
You may not qualify if:
- Subject has a known or suspected sensitivity to dexamethasone acetate (DXA)
- Subject is enrolled in any other concurrent study, without prior approval from BSC
- Women of childbearing potential who are or might be pregnant at the time of study enrollment
