The purpose of this study is to evaluate whether treatment with ISIS CRP Rx can reduce AF (Atrial Fibrillation) burden (percentage of time spent in AF) in subjects with paroxysmal AF
The hypothesis of this study was that early re-ablation (test) was superior to AAD therapy (control) in patients with previous failed PVI ablation for paroxysmal AF.
This study will be divided into two phases. The purpose of the Phase I registry is to assess the current force being used for ablation of symptomatic paroxysmal AF in a wide range of operators in different Canadian centres with the operators being blinded to the contact force data. In Phase II of the study, operators will have open use of the force contact data. Phase I and II data will be compared in order to assess the efficiency of using the THERMOCOOL® SMARTTOUCH™ catheter.
The purpose of the study is to determine the permanency of PV isolation with the Arctic Front Advance cryoablation system in paroxysmal AF patients. It will also provide data on acute procedural outcomes and measures as well as clinical AF recurrence in these patients approximately 3 months post-ablation.
The aim of this prospective randomized double-blind study was to compare the efficacy and safety of cryoballoon ablation with the RF approach in the treatment of paroxysmal AF after failed first radiofrequency ablation.
The purpose of this randomized, double blind, placebo-controlled, superiority clinical trial was to assess clinical efficacy of antazoline in rapid conversion of atrial fibrillation during observation sinus rhythm.
The Genesis Feasibility Study will collect clinical information on the use of the Bard Over-the-Wire Mesh Ablation System to access and perform electrophysiological mapping, cardiac stimulation and radiofrequency ablation in the region of the pulmonary vein (PV) ostia for the treatment of patients with Paroxysmal Atrial Fibrillation. Patients will be followed up for 12 months to assess the primary safety endpoint of Major Complications (a composite safety endpoint)and effectiveness, defined as Long-Term Success (freedom from recurrent atrial arrhythmia.
The purpose of this study is to assess the safety and effectiveness of the Circular and Crescent Mapping and Ablation catheters and the workflow of the Multi-Electrode Irrigated Pulmonary Vein Isolation System when used for the treatment of drug refractory symptomatic paroxysmal atrial fibrillation (PAF).
The TOCCASTAR Study will assess the safety and effectiveness of a contact force sensing catheter used for ablation in patients with paroxysmal atrial fibrillation. Subjects will be randomized for treatment with either the TactiCath catheter or another ablation catheter with no contact force sensing capability. Patients will be followed for 12 months to compare the incidence of serious adverse events and freedom from recurring, symptomatic AF between the two study arms. Additional measures of treatment success including quality of life, recurrence of asymptomatic AF and procedural efficiency will also be studied. A second phase of the study will treat up to 50 non-randomized subjects with a new version of the device under the same protocol.
