Catheter Ablation Versus Amiodarone for Shock Prophylaxis in Defibrillator Patients With Ventricular Tachycardia (CEASE-VT)

January 17, 2020 updated by: Population Health Research Institute

Catheter Ablation Versus Amiodarone for Shock Prophylaxis in Defibrillator Patients With Ventricular Tachycardia: A Multi-center Randomized Trial

Implantable Cardioverter Defibrillators (ICDs) provide a shock or pacing therapy to bring back a normal heart beat when a patient experiences a dangerous abnormal heart rhythm such as ventricular tachycardia (VT). ICDs are very successful in bringing back a normal heart beat when VT occurs, but they do not prevent further dangerous heart rhythms from occurring. This study is designed to determine the best way to manage patients who have an ICD and who continue to have episodes of VT. There are two methods for treatment the VT: 1) Ablation, and 2) Medication.

An ablation procedure involves placing a flexible catheter (insulated wire) in the groin area and threading it into the heart. After the doctor has located the affected area responsible for the VT, radiofrequency energy is delivered by the power generator through the catheter to the inside of the heart. The radiofrequency energy ablates (burns) a small area of the heart tissue thought to cause the VT.

A medication called Amiodarone is an "anti-arrhythmic" prescribed to prevent abnormal heart rhythms from recurring.

The purpose of this study is to compare these two different methods for treating VT. Treatment with ablation and amiodarone are both considered the standard of care for patients with VT but they have not been compared directly in a study like this before.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years to 84 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Appropriate ICD Therapy, Slow VT or Sudden Cardiac Death
Time Frame: From 30 days following randomization until final follow-up visit

Number of participants with a composite outcome of any of:

  1. Appropriate Implantable Cardioverter Defibrillator (ICD) therapy [Including antitachycardia pacing (ATP) and shocks]
  2. Slow ventricular tachycardia (VT) below ICD detection threshold leading to hospitalization or necessitates antiarrhythmic medications and/or catheter ablation
  3. Sudden Cardiac Death
From 30 days following randomization until final follow-up visit

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
