COCONUT Study Concomitant PVI and LAAC
In patients with non-valvular AF, at high stroke risk, and who are ineligible for long-term oral anticoagulation LAAC could be an alternative to anticoagulation and safety and efficacy has been shown in several studies and registries.8 While PVI and LAAC are both conducted in the left atrium and share the …
Stepwise Strategy for Treatment of Atrialfibrillation Substrate Study
Electrical/pharmacological cardioversion improves structural remodeling of left atrium. We hypothesized that radiofrequency ablation surgery for atrial fibrillation has a higher success rate and a lower recurrence rate of atrial fibrillation in patients with improved atrial stroma. This study is a multicenter, prospective, observational study conducted in China to evaluate whether …
Intracardiac Echocardiography Guided Watchman Device Implant
This study is to look at the success of Intracardiac Echocardiography (ICE) in the Watchman procedure. Currently the process is to use a Transesophageal Echocardiography (TEE) to place the Watchman in patients. This study is aiming to show how the ICE is just as effective in placing the device correctly …
A Prospective Observational Study Evaluating the Incidence of Silent Cerebral Lesions and Procedural Safety Following Atrial Fibrillation Ablation Using the VARIPULSE™ Pulsed Field Ablation System
Study Type: Observational Study Goal The goal of this study is to evaluate the incidence and burden of silent cerebral lesions (SCLs) detected on brain magnetic resonance imaging (MRI) after pulsed field ablation (PFA) for atrial fibrillation (AF). PFA is a new non-thermal ablation technique that selectively targets cardiac tissue …
VASC-AF Study: Vascular Closure vs Manual Compression
The aim of this study is to reduce the time to ambulation after PVI by a vascular closure device as compared to manual compression and a figure-of-8 suture only. Safety, efficacy and feasibility of the VASCADE MVP device should be proven, too. The definition of endpoints will be trained in …
Feasibility, Safety, Cost-effectiveness, and Environmental Impact of Reprocessed Ablation Catheters in PVI
This study evaluates whether re-sterilized (reprocessed) ablation catheters are as effective and safe as new ablation catheters when used for pulmonary vein isolation in patients with atrial fibrillation. Adult patients scheduled for catheter ablation will be randomly assigned to undergo the procedure using either a new catheter or a re-sterilized …
Ablation of Human Cardiac Fibrillation Based on Models of Hierarchical Organization of Tissue Excitation
The mechanisms that maintain persistent atrial fibrillation (AF) in humans remain unknown. In the research project PI18/01268 funded in the previous call for Strategic Action in Health, the group has demonstrated that the hierarchical organization of (i) rotational domains, (ii) frequency domains and (iii) physiological responses to pharmacological provocation with …
Electroporation Treatment for Early AF Management in Heart Failure With Preserved Ejection Fraction (HFpEF) Pilot Study
The proposed pilot study is a prospective, randomized, single-center feasibility study, enrolling 200 patients with symptomatic paroxysmal AF. Per protocol, 100 patients will undergo a FARAPULSE electroporation PVI and 100 patients will receive standard AF medical treatment. Prior enrollment, all patients will be informed on the risk and benefits of …
Comparative Study on the Safety and Efficacy of Using AccuSafe Transseptal Guidewire Versus Traditional Transseptal Needle for Transseptal Puncture in non-or Free- Guidance
Research Title: Comparative study on the safety and effectiveness of AccuSafe transseptal guidewire versus traditional transseptal needle for transseptal puncture without X-ray guidance Research Objective: This study aims to compare the safety and effectiveness of the AccuSafe guidewire with the traditional transseptal needle in performing X-ray-free transseptal puncture under ICE …
AlEX-DHF: Ablation and Exercise in Diastolic Heart Failure
The investigators analyze the impact of exercise and ablation in patients with symptomatic short-persistent atrial fibrillation (Afib) and heart failure with preserved ejection fraction (HFpEF). It is hypothesized that the combination of ablation and exercise better improves peak oxygen consumption (VO2peak) through improvement of peripheral (exercise training) and central (ablation) …
