COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

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
the imaging probe for echocardiographic imaging will be will be performed using a catheter probe with the ability to use echo to image cardiac structure like the right atrium to visualize the intra atrial septum where a catheter for ablation will be passed through a sheath to deliver therapy. This is performed by an electrophysiologist. The setting is in a catheterization lab. Imaging will occur only once in the first part of the procedure prior to therapy and typically is in the range of 10 minutes or less depending upon ability to visualize the septum.

Outcomes
Primary outcome [1] 322729 0
Tracking and analyzing the type of adverse events reported and proportion of participants with and without adverse events related to the use of the investigational catheter insertion and imaging through procedure completion. Routine events experienced during catheterization include i.e. vessel damage, air embolism or allergic reactions will be assessed post procedurally and compared to standard of care intracardiac echo catheters. Safety outcomes will be assessed through 24 hours post procedure including bleeding or embolic events using data collection forms and anticipated adverse events as described in the instructions per use.
Timepoint [1] 322729 0
Events will be assessed through procedure completion and 24 hours post procedure.
Secondary outcome [1] 379481 0
Tracking and analyzing the type of adverse events experienced during catheterization will be assessed through 7 days post procedure and compared to adverse events in the literature using intracardiac echo catheters using standardized data collection forms.
Timepoint [1] 379481 0
Events will be tabulated through 7 days post procedure. Potential adverse events include those experienced in routine catheterization procedures where a catheter is inserted into a vessel. Examples would be vessel damage, hematoma, air embolism and allergic reactions.
Secondary outcome [2] 381473 0
User Questionnaires assessing 2D and 3D imaging quality and ability to visualize cardiac structures will be completed by users. Ratings are tabulated using a Likert Scale rating quality of visualization between 1-5. One (1) = not imaging at all to five (5) very good imaging.
Timepoint [2] 381473 0
Ratings will be tabulated post procedurally.

Summary
Brief summary
The device studied in this trial is an intracardiac echocardiographic catheter intended for intracardiac and intraluminal visualization of cardiac and great vessel anatomy and physiology in the heart of adult and pediatric patients. It is for imaging guidance only.
The study is intended to evaluate images acquired by the catheter during percutaneous procedures in which access to the left atrium is performed via transseptal puncture.
Safety criteria based on ability to image adequately as evidenced by the absence of device or procedure related adverse events.
