A Novel Healthcare Information Technology Tool to Improve Care in Patients With Atrial Fibrillation
open to eligible people ages 18 years and up
Patients with implantable heart devices including pacemakers, defibrillators, and cardiac monitors may not seek regular medical care related to their implanted devices. These devices are capable of detecting abnormal heart rhythms or other device abnormalities that may benefit from clinical action or oversight. A novel healthcare information technology has been developed and is being implemented clinically for screening of patients with cardiac rhythm devices who seek care in the emergency room setting. This study seeks to examine differences in detection of cardiac rhythm disturbances including atrial fibrillation (AF) with utilization of this new screening technology, and how often treatment plans change in patients who have a heart rhythm abnormality detected.

Substrate Versus Trigger Ablation for Paroxysmal Atrial Fibrillation
open to eligible people ages 21 years and up
This is a prospective randomized study to assess the safety and efficacy of FIRM (Focal Impulse and Rotor Modulation)-guided ablation for the treatment of symptomatic atrial fibrillation (AF). The study hypothesis is that the efficacy of AF elimination at 1 year will be higher by ablating patient-specific AF-sustaining rotors and focal sources by Focal Impulse and Rotor Modulation (FIRM) compared to conventional ablation alone (wide-area PV isolation).

aMAZE Study: LAA Ligation Adjunctive to PVI for Persistent or Longstanding Persistent Atrial Fibrillation
Sorry, in progress, not accepting new patients
This study is a prospective, multicenter, randomized (2:1) controlled study to evaluate the safety and effectiveness of the LARIAT System to percutaneously isolate and ligate the Left Atrial Appendage from the left atrium as an adjunct to planned pulmonary vein isolation (PVI) catheter ablation in the treatment of subjects with symptomatic persistent or longstanding persistent atrial fibrillation. This study will be conducted in two stages: - Limited Early Stage (Stage 1): up to 250 subjects at up to 65 sites. (COMPLETED, transitioned to Stage 2) - Pivotal Stage/ Phase III (Stage 2): up to 600 subjects at up to 65 sites. (COMPLETED) All subjects from both stages will be included in the primary analysis.

Effectiveness Study of Circumferential vs. Segmental Ablation in Paroxysmal Atrial Fibrillation
Sorry, in progress, not accepting new patients
This is a PI-initiated study that aims to evaluate the efficacy of two different methods of paroxysmal atrial fibrillation (PAF) ablation. There are currently two strategies for PAF ablation that are routinely performed by electrophysiology clinicians: (1) circumferential pulmonary vein ablation (CPVA) and (2) segmental pulmonary vein isolation (SPVI). However, it is not known if one approach is better than the other. This randomized study will evaluate and compare the efficacy of CPVA versus SPVI in subjects undergoing ablation for paroxysmal atrial fibrillation only. Subjects will have a 50/50 chance of receiving either the CPVA or SPVI ablation method.

Evaluation of Conventional Ablation With or Without Focal Impulse and Rotor Modulation to Eliminate Human AF
Sorry, not currently recruiting here
This prospective randomized study will assess the safety and efficacy of FIRM-guided ablation (FIRM+PVI) compared to pulmonary vein isolation (PVI) without FIRM, for the treatment of symptomatic atrial fibrillation.

TactiFlex AF IDE Trial
Sorry, not currently recruiting here
Prospective, non-randomized multi-center clinical investigation. Design includes a main study and a separate substudy. Subjects in the main study are to be treated using the full range of ablation power settings in the IFU. Subjects in the substudy are to be treated in the upper end of the recommended ablation power settings (40-50 Watts).
