Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - MultiPulse Therapy

Experimental: Intervention - The study will be conducted using the venous cannulations that are standard of care for the indicated procedure. Additional access points may be necessary if access to coronary sinus is difficult from existing femoral venous cannulations. Sterile study leads or EP catheters will be temporarily placed into the RA, CS, and RV (for R-wave sensing using intracardiac electrograms - optional) which will be connected to the investigational device (CESS).

Up to two MPTs will be delivered and subject responses following each MPT regarding perception and acceptability of MPT to treat AF will be obtained. MPT voltages will not exceed 100V.
