Observational Study to Examine the Procedural and Outcomes of AF Ablation Assisted by STAR Apollo™ Mapping System

October 14, 2024 updated by: Kansas City Heart Rhythm Research Foundation
STAR Apollo Mapping System is an FDA cleared mapping technology that can analyze the signals collected during the ablation procedure on the 3D mapping system and give the physician further insight into the AF activation patterns which may assist them in identifying areas responsible for maintaining Atrial Fibrillation (AF). The STAR Apollo Mapping System system allows clinicians, after treating the Pulmonary Veins (PV), to collect data from the atria during clinical AF procedures using standard FDA cleared catheters and devices. This study aims to examine the impact of the STAR Apollo Mapping System on procedural and acute outcomes in a multicenter observational study.

Detailed Description

Atrial fibrillation (AF) is the most common heart rhythm abnormality. It affects 1 in 100 people. It can cause unpleasant symptoms of palpitation, shortness of breath and in some can cause heart failure or stroke. AF is triggered by abnormal electrical signals originating both in the pulmonary veins (PV), the veins that drain blood from the lungs into the heart, and in the rest of the left atrium, the heart chamber that the PVs drain into. AF can be successfully treated by a procedure called catheter ablation. This involves passing a wire up the vein at the top of the leg and delivering radiofrequency energy to the atrial tissue. This renders that tissue electrically inert. For many years this procedure has been guided by 3D cardiac mapping systems capable of showing the position of the catheters in the heart and recording their electrical signals. By doing a series of radiofrequency treatments around the mouth of the PVs it is possible to electrically isolate them so that PV signals cannot start or sustain AF. This leaves the left atrial signals untreated and limits the success of the procedure to 50%. To date clinicians have tried numerous ways to identify these remaining left atrial signals, but so far, their efforts have not improved the outcomes of ablation over just isolating the PVs alone (50% success rate). STAR Apollo Mapping System is an FDA cleared mapping technology that can analyze the signals collected during the ablation procedure on the 3D mapping system and give the physician further insight into the AF activation patterns which may assist them in identifying areas responsible for maintaining AF. The STAR Apollo Mapping System system allows clinicians, after treating the PVs, to collect data from the atria during clinical AF procedures using standard FDA cleared catheters and devices. This study aims to examine the impact of the STAR Apollo Mapping System on procedural and acute outcomes in a multicenter observational study.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients who have been referred for persistent AF catheter ablation, who have already had AF recurrence post PVI, will be considered for this study.

Description

Inclusion Criteria:

  • Indication for ablation of persistent AF
  • Age >18 years
  • Persistent AF >7 days and total continuous duration <2 years
  • Patients have previously undergone pulmonary vein isolation, using any technique and have had AF recurrence.
  • Patients have limited additional ablation at their first procedure (e.g. right atrial flutter line).

Exclusion Criteria:

  • Patients with previous ablation in more than one region of the left atrium in addition to the pulmonary veins.
  • Patients with longstanding persistent AF (continuous duration >2 years) or significant substrate (mitral valve disease, scarring, very dilated atria >50mm).
  • Creatinine clearance estimated glomerular filtration rate (eGFR) <30mls/min
  • Contraindication to anticoagulation
