Filter by:This study aims to evaluate the safety and efficacy of a three-dimensional navigation intracardiac guidance kit to perform atrial septal puncture in patients requiring catheter ablation, which will be compared with procedures using traditional kit for atrial septal puncture.
This is an investigator-initiated virtual (or decentralized) trial that includes a postal parcel (mail-in) containing sensors for SA diagnosis (NightOwl™) and physical activity (SENS Motion), in addition to smart-phone based heart rhythm (FibriCheck) monitoring in participants with paroxysmal or persistent AF. A case-coordinator (the investigators) will manage all participant contacts virtually during the study from inclusion to follow-up.
In this clinical trial, Rivaroxaban of standard dose (20mg) and reduced dose (15mg) will be administeted in non-valvular atrial fibrillation patients without severe renal dysfunction. It is a randomized, open-label, and phase 4 clinical trial to compare and evaluate efficacy and safety of Rivaroxaban. After obtaining informed consent to participate in this trial, screening is performed (Screening visit). Screening includes baseline 12-lead electrocardiography and laboratory tests to exclude severe end-organ dysfunction (such as renal dysfunction, liver dysfunction, or anemia). Baseline visits are available on the same day. After screening, subjects eligible for the trial will be randomly assigned (1:1 ratio) to Group 1 (15 mg of Rivaroxaban) or Group 2 (20 mg of Rivaroxaban) (Baseline visit). The study drug (Rivaroxaban 15mg or 20mg daily) will be administered for 12 months. During study period, a total of six visits (3,6,9,12 months) will be made, and follow-up test and outcome measurement will be done in each visit.
Oral anticoagulation (OAC) is indicated in a wide variety of clinical conditions including atrial fibrillation (AF), mechanical valve prosthesis (MVP), deep vein thrombosis and pulmonary embolism. Although direct OAC has replaced vitamin K antagonists (VKA) in non-valvular AF due to lower bleeding risk, it's still recommended to use VKA specifically in cases of valvular AF, MVP and anti-phospholipid syndrome. VKA has a narrow therapeutic range and multiple drug interactions causing unpredicted pharmacodynamics. This requires regular monitoring of the international normalized ratio (INR) level to ensure it's in the target therapeutic range and prevent extreme values that may result in thrombo-embolic events or sometimes fatal bleeding. Self-INR monitoring and management have emerged recently as a safe cost-effective alternative to standard management, with evidence of tighter control of INR, reduction of thrombo-embolic events, and improving treatment-related quality of life. However, there are no specific criteria for patient selection. Whether the level of education and other social factors would affect the outcomes of self-management is still not clear. Owing to the wide geographical area served by Aswan Heart Center, many patients have to cover long distances to follow up their INR and seek medical advice regarding adequate dose modification. This may result in reluctance and non-compliance to clinic visits and INR testing. Proper education, training and providing an alternative near place to measure the INR and self-adjust warfarin dose is expected to improve patient adherence and compliance.
Quantify the effect of an innovative weight loss management on rhythm control.
The rational behind this observational study is to collect real life data about the use of Trombix® (Rivaroxaban) among patients with atrial fibrillation in Algeria . The aim is to evaluate the safety, efficacy and quality of life.
The goal of this clinical trial is to compare two different, market approved, cryoballoon devices for the treatment of paroxysmal atrial fibrillation (AF). The main aims of the study are: - to compare the efficacy of two ablation devices (acute and 1 year success rates) - to compare the procedural characteristics (procedure duration, fluoroscopy duration, ablation time - to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon. Standard of care cryoballoon procedure will be performed alongside with standard postprocedural follow-up. • to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon.
Pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (PAF) has limited success. The superior vena cava (SVC) has been identified as one of the most common non-pulmonary vein triggers for PAF. It is estimated that SVC isolation (SVCI) could improve the clinical results of patients with PAF. However, results from previous studies about SVCI remain controversial. Safety concerns for SVCI may outweigh its benefits and lead to inadequate ablation. To address this issue, the introduction of a quantitative ablation index (AI) for SVCI may provide a solution. Therefore, the investigators sought to initiate a retrospective, multi-center study, to explore the efficacy and safety of quantitative SVCI in addition to PVI in PAF.
Pilot, randomized, unblinded, feasibility and proof of concept clinical trial randomizing 50 patients in a 1:1 ratio to hybrid ablation or catheter ablation
This study aims to investigate the long-term efficacy and safety of incorporating ganglionated plexus ablation into radiofrequency ablation strategies for persistent atrial fibrillation.
