Efficacy, Safety and Efficiency of the nMARQ Pulmonary Vein Isolation System in Paroxysmal Atrial...
Paroxysmal Atrial FibrillationThis is a pilot study designed to investigate the effectiveness of the nMARQ Pulmonary Vein Isolation system in the treatment of Paroxysmal Atrial Fibrillation (AF) at different ablation settings. AF is a common condition which causes a fast and erratic heartbeat. There are estimated to be 50,000 new cases diagnosed per year in the UK. The fast heart beat can cause symptoms such as palpitations, lightheadedness, chest pains, shortness of breath and fatigue. Catheter ablation is a technique used for the control of AF. In this procedure a catheter (a long thin wire) is passed into the chambers of the heart via a large blood vessel in a leg. The tip of the catheter can destroy tiny sections of heart tissue that may be the source or trigger of the abnormal electrical impulses. One of the challenges of AF ablation is to maximize success rates, as such there is currently rapid advances in technology to carry out this procedure. Different catheters exist which deliver this energy in different ways. This study uses one such system to perform this procedure. It is called the nMARQ system for Pulmonary Vein Isolation produced by Biosense Webster. Currently this system is used in practice in the UK for patients with this medical condition. What we seek to research is when ablating what is the optimum setting to perform ablation at. There is currently no data to guide best clinical practice in this area.

IMPACT: A Safety and Feasibility Study of the IOWA Approach Cardiac Ablation System
Paroxysmal Atrial FibrillationIMPACT is a prospective, single-arm, multi-center, safety and feasibility study evaluating the IOWA Approach Cardiac Ablation System (FARAPULSE, Inc.) for the treatment of paroxysmal atrial fibrillation.

Atrial FibrillationHeart DiseasesThe BRAKE-AF Study is a phase III, randomised, controlled, multicentric, open-label clinical trial to prove the noninferiority of ivabradine versus digoxin in the treatment of permanent atrial fibrillation. The total duration of the study is 3 years, with 24 months of enrolment, treatment and follow-up.

Atrial FibrillationAtrial Fibrillation Paroxysmal2 moreThis study is a prospective, randomized controlled study to compare overall clinical outcomes between High Power Short Duration (HPSD) and standard radiofrequency (RF) ablation settings for Atrial Fibrillation (AF) ablation in the treatment of subjects with paroxysmal or persistent Atrial Fibrillation.

Study to Gather Information About the Proper Dosing of the Oral FXIa Inhibitor BAY 2433334 and to...
Atrial Fibrillation (AF)The purpose of this study is to try to find the best dose of the new drug BAY 2433334 to give to participants and to look at how well BAY 2433334 works in patients with irregular heartbeat (atrial fibrillation) that can lead to blood clots, stroke and other heart-related complications. In addition researchers want to compare the safety of the study drug to apixaban, a non-vitamin K oral anticoagulant (NOAC) in patients with atrial fibrillation. This study is also done to learn how the drug in this study moves into, through and out of the body. BAY 2433334, works by blocking a step of the blood clotting process in our body and thins the blood and is a so called oral FXIa inhibitor. Apixaban, works by reducing the production of blood clotting factors in our body and thins the blood and is a so called non-vitamin K oral anticoagulant (NOAC). Thinning the blood can prevent you from blood clots which can cause a stroke.

Evaluation of VISITAG SURPOINT™ Module With External Processing Unit (EPU)
Paroxysmal Atrial FibrillationProspective, non-randomized, post market clinical evaluation of the VISITAG SURPOINT™ Module with External Processing Unit (EPU) when used with STSF catheter and ST catheter compared to an historical control performance goal. A maximum of 330 subjects will be enrolled across up to 45 sites. Two hundred eighty (280) enrolled subjects will be treated using the STSF catheter with EPU and 50 subjects will be treated using the ST catheter with EPU. Prior to enrollment, a few sites will be selected to only enroll subjects who will be treated with the ST catheter and the remaining sites will only enroll subjects who will be treated with the STSF catheter. Bayesian adaptive design will be used to assess early success at up to two interims: one after all subjects have completed the 3- month follow-up assessment, and a second to occur after all subjects have completed the 6 months follow-up visit.
