Dipole Density Right Atrial Mapping and Assessment of Therapy In Cavotricuspid Isthmus Flutter (DDRAMATIC)

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 evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01872052
Recruitment Status : Completed
First Posted : June 7, 2013
Last Update Posted : March 7, 2017
Information provided by (Responsible Party):
Acutus Medical

Brief Summary:
Study to determine the feasibility of the Acutus Medical System in obtaining data to create Dipole Density Maps of electrical activation in the right atrium in patients with typical atrial flutter.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 9 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Dipole Density Right Atrial Mapping and Assessment of Therapy In Cavotricuspid Isthmus Flutter
Study Start Date : March 2013
Actual Primary Completion Date : June 2014
Actual Study Completion Date : August 2014

Arm Intervention/treatment
Experimental: Acutus Medical System Device: Acutus Medical System Mapping
Mapping with the Acutus Medical System followed by intracardiac ablation of typical atrial flutter

Primary Outcome Measures :
  1. The number of patients in which offline construction of pre- and post-treatment activation maps can be completed [ Time Frame: 3 months post-procedure ]
    Proprietary software algorithms will be used generate electrical activation maps based dipole density data acquired by the Acutus Medical Catheter during the procedures. These activation maps will then be applied to a 3D model of the endocardial surface to create a 3D activation map.

  2. The number of patients that experience a device-related adverse events as a measure of safety and tolerability [ Time Frame: 7 days post-procedure ]
