Safety and Effectiveness Evaluation of the Multi-Electrode Radiofrequency Balloon Catheter for the Treatment of Symptomatic Paroxysmal Atrial Fibrillation (STELLAR)
Design and objective: Prospective, multicenter, single-arm study to determine the safety and 12-month effectiveness of the multielectrode radiofrequency balloon catheter for the treatment of drug-refractory paroxysmal atrial fibrillation.
Evaluation of QDOT MICRO™ Catheter for Pulmonary Vein Isolation in Subjects With Paroxysmal Atrial Fibrillation (Q-FFECIENCY)
Design and objective: Prospective, nonrandomized, premarket clinical evaluation to demonstrate the safety and effectiveness of the QDOT MICRO™ Catheter compared with a historical control performance goal in subjects undergoing electrophysiology mapping and radiofrequency ablation for treatment of drug-refractory, symptomatic paroxysmal atrial fibrillation.
VISITAG SURPOINT™ US POSTAPPROVAL Study
Evaluation of VISITAG SURPOINT™ Module With External Processing Unit (EPU)
Design and objective: Prospective, nonrandomized, postmarket clinical evaluation to determine the 12-month effectiveness of Tag Index-guided ablation using the THERMOCOOL SMARTTOUCH® SF and the THERMOCOOL SMARTTOUCH® Catheters with VISITAG SURPOINT™ Module with EPU for pulmonary vein isolation in the treatment of drug-refractory, symptomatic paroxysmal atrial fibrillation.
WaveCrest Vs. Watchman TranssEptal LAA Closure to Reduce AF-Mediated Stroke 2 (WAVECREST2)
Design and objective: Prospective, multicenter, randomized, active control study of the Coherex WaveCrest™ Left Atrial Appendage (LAA) device compared to the Watchman® LAA device for the reduction in risk of ischemic stroke or systemic embolism in subjects with nonvalvular atrial fibrillation who seek a nonpharmacologic alternative to chronic oral anticoagulation.
