Biventricular Tachycardias Outcome Trial - Full Text View

Sponsor:	Sorin Group
Information provided by:	Sorin Group
ClinicalTrials.gov Identifier:	NCT00729235

Purpose

This clinical investigation is a device-based open, prospective, multicenter two-arm randomized trial, comparing patients who are treated in the slow VT zone versus patients who are not treated in that zone.

The device intended to be used is the OVATIOTM CRT model 6750 but future generation of Sorin Group/ ELA Medical devices may be used provided they are CE marked. Ethics committees and health authorities will be informed prior to any use of a newer device if applicable.

All patients will have a 3-zone detection configuration programmed. The slow VT zone will be defined by programming the detection parameters as follows:

Slow VT detection rate: 100 bpm (or if the resting rate is higher than 80 bpm, we recommend to adjust this parameter to: resting rate + 30 bpm)
VT detection rate: 150 bpm

PARAD+ will be the first choice for SVT/ST and VT discrimination in the VT zones.

The Fast VT and VF limits are left to investigator's judgment. Therapy on VT, fast VT and VF are also left to the investigator's judgment.

Patients will be randomized at implant to have the slow VT zone programmed as a monitoring zone (monitoring arm) or to have therapies programmed within the slow VT zone (therapy arm). The randomization table will be generated by Sorin Group/ELA Medical.

Primary Outcome Measures:

Incidence of slow ventricular tachycardias (Slow VTs) in CRT-ICD pts; [ Time Frame: 24 months ] [ Designated as safety issue: No ]
ATP therapy efficacy on slow VTs conversion. [ Time Frame: 24 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Efficacy of ATP therapies on Slow VTs according to therapy setting (delivery in LV only, in RV only, or in LV+RV) [ Time Frame: 24 months ] [ Designated as safety issue: No ]
Tvar risk stratification [ Time Frame: 24 months ] [ Designated as safety issue: No ]
"unscheduled visits" or "hospital re-admissions" due to slow VTs; [ Time Frame: 24 months ] [ Designated as safety issue: No ]
Incidence of adverse events (AEs) in the studied population [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	404
Study Start Date:	May 2006
Estimated Study Completion Date:	December 2008
Estimated Primary Completion Date:	December 2008 (Final data collection date for primary outcome measure)
