Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Once suitable participants have signed the consent form, they will undergo a cardiac procedure. These participants are patients who are already having a planned procedure where they are likely to experience Ventricular Tachycardia (VT) or Ventricular Fibrillation (VF). The CellAED device is a novel automated external defibrillator. The cardiologist will place the CellAED onto the patient's chest once in theatre, prior to the commencement of surgery.

During the procedure, participants will be connected to the CellAED, along with a back-up defibrillator. Once patients experience an arrhythmia (either spontaneous or induced), the CellAED will be deployed to deliver a defibrillation therapy and revert the patient to normal sinus rhythm. This will only be applied to a maximum of 1 time. A back up standard defibrillator will be used if the Cell AED device fails to successfully restore normal rhythm following a single shock delivery from the CellAED. The CellAED will then be removed from the patient. The use of the CellAED will be confined to the duration of the surgical procedure only. The use of the device including placement, therapy delivered, and outcome, will be reported in the patients medical records.

Prior to surgery, all involved staff members will be trained on the appropriate use of the CellAED device in a single 30 minute training session. This training will be provided by the study sponsor onsite at the hospital in a one-to-one training session and will utilize a CellAED trainer device. All training will be documented and only trained users will be able to use the device. All users will have access to the trainer device and the instructions for use (IFU) document. This IFU document has been created specifically for this trial.

Outcomes
Primary outcome [1] 326198 0
Efficacy: To evaluate the efficacy of the CellAED to appropriately revert a patient in VT or VF to normal sinus rhythm. This is a composite assessment of the following:

- Device output (measured in Joules by the device)
- Device Current (measured in Amps by the device)
- Transthoracic impedance (measured in Ohm by the device)
- Reversion of VT or VF to normal sinus rhythm for at least 5 seconds, assessed using ECG
Timepoint [1] 326198 0
This will be assessed immediate following the deployment of the CellAED therapy.
Secondary outcome [1] 390475 0
Safety: Patient Safety will be evaluated based on the frequency of adverse events (including local tissue trauma) across the trial, assessed in accordance with the Common Terminology Criteria for Adverse Events (CTCAE, version 5).
Timepoint [1] 390475 0
This will be continually assessed for the duration of the surgical procedure and on a post-operative assessment at the conclusion of the surgery.
Secondary outcome [2] 390476 0
Clinical performance: This will be assessed by analysing the patient's heart rhythm using 12 lead ECG recorded during episode of VF or VT.
Timepoint [2] 390476 0
This will be continually assessed for the duration of the surgical procedure.
Secondary outcome [3] 390477 0
Usability will be assessed using an evaluation form completed by the user (attending cardiologist, including assessment of "Snap Peel Stick" methodology. This is an evaluation form that has been designed specifically for this project.
Timepoint [3] 390477 0
Completed within 1 hour post-operatively.

Statistical methods / analysis
Successful delivery of shock: Efficacy of the defibrillation will be evaluated by the successful termination of the VT/VF episode and reversion to a NSR for a period of 5 seconds.

The secondary objectives will be assessed using descriptive statistics. Categorical variables will be summarized by frequencies and percentages. Continuous variables will be summarized by means, standard deviations, minimums, medians and maximums where appropriate. Confidence intervals will be calculated as appropriate. Type 1 error for the study will be set to 0.05.
Calculation of sample size is based on previously published literature suggesting adequate sample size to demonstrate the efficacy of defibrillation to revert a patient to NSR. There are a variety of factors including ischemia, metabolic or electrolyte derangements, autonomic tone, and medications can affect the success of defibrillation. We have selected a number large enough to demonstrate efficacy, while reducing the number of patients exposed to therapy.

Summary
Brief summary
The CellAED device is a novel automated external defibrillator (AED) or commonly referred to as a defibrillator. The purpose of this study is to test this new AED and demonstrate its ability to deliver an appropriate shock to help restore a patient in cardiac arrest to a normal heart rhythm. The hypothesis is that the CellAED will be able to terminate arrhythmias (VT or VF) in a patient to allow the heart to restore a Normal Sinus Rhythm.

Once consented, patients will be scheduled for the cardiac procedure. Patients will have the CellAED applied to their chest prior to the procedure starting.

In addition, as a safety precaution, patients will have a traditional defibrillator applied to their chest as a rescue therapy device should the first shock delivered by the CellAED fail to revert the patient to normal sinus rhythm.

During the procedure, if patient experiences a shockable rhythm (VT/VF) the cardiologist will activate the CellAED (in accordance with instructions in the Instructions for Use).
This will be performed up to a maximum of one (1) time. The rhythm will be immediately assessed and if required, back up defibrillation will be delivered utilizing the standard defibrillator available on site.
