Filter by:The overall goal of this study is to evaluate the effectiveness of a previously developed storytelling intervention on anticoagulation (AC) initiation/persistence in African American and Black patients with atrial fibrillation/flutter. The investigators hope to gain knowledge that may help treat atrial fibrillation or flutter and lower stroke and adverse cardiovascular event risks for African American and Black patients by increasing the use of blood thinning medications known as anticoagulants.
Patients with cardiac pathology and arrhythmias including those who have indications for pacemakers implantation will be included in the study. We will determine the influence of pacemaker implantation with the localization of the ventricular electrode in the top of the right ventricle or the middle third of the right ventricle according to echocardiographic and electrocardiographic parameters, congestive heart failure progression, patients' quality of life and follow-up therapy of patients with identified myocardial fibrosis with existing pacemaker. Study of changes in echocardiography, electrocardiography, myocardial fibrosis markers, the quality of life of patients will allow to choose the most optimal localization of the ventricular electrode during implantation of the permanent pacemakers system in order to improve the quality of life of the patients.
The VISABL-AFL clinical investigation is a prospective, single-arm, multi-center, interventional, Investigational Device Exemption (IDE) trial. The primary objectives of VISABL-AFL are to assess the safety and efficacy of radiofrequency (RF) ablation of type-I atrial flutter performed with the Vision-MR Ablation Catheter 2.0 in the iCMR environment.
"Chang Gung ECG Abnormality Detection Software" is a is an artificial intelligence medical signal analysis software that detect whether patients have abnormal ECG signals of 14 diseases by static 12-lead ECG. The 14 diseases were - Long QT syndrome - Sinus bradycardia - Sinus Tachycardia - Premature atrial complexes - Premature ventricular complexes - Atrial Flutter, Right bundle branch block - Left bundle branch block - Left Ventricular hypertrophy - Anterior wall Myocardial Infarction - Septal wall Myocardial Infarction - Lateral wall Myocardial Infarction - Inferior wall Myocardial Infarction - Posterior wall Myocardial Infarction The main purpose of this study is to verify whether "Chang Gung ECG Abnormality Detection Software" can correctly identify abnormal ECG signals among patients of 14 diseases. The interpretation standard is the consensus of 3 cardiologists. The results of the software analysis will be used to evaluate the performance of the primary and secondary evaluation indicators.
Demonstrate the safety and effectiveness of the Ablacath™ Mapping Catheter and Ablamap® System in patients with all types of atrial fibrillation (AF) including paroxysmal or persistent or long-standing persistent, undergoing and De Novo or Redo procedures. Phenotype patients and demonstrate the prognostication power of Electrographic Flow (EGF®) maps among all subjects using 12-month follow-up outcomes following EGF-guided mapping and ablation.
Atrial fibrillation (AF) is the most common clinical arrhythmia and the prevalence increases with age. AF increases the risk of ischaemic stroke fivefold and accounts for almost one-third of all strokes. As AF is often asymptomatic there are many undetected cases. It is important to find patients with AF and additional risk factors for stroke in order to initiate oral anticoagulation treatment, which can reduce the risk of an ischaemic stroke by 60-70%. Screening is recommended in European guidelines, however the most suitable population and the most suitable device for AF detection remain to be defined. The main objective of this study is to test the hypothesis that AF screening with 14-days continuous ECG monitoring in high-risk individuals identified with a risk prediction model is more effective than routine care in identifying patients with undetected AF. Effectively detecting AF among patients with risk factors for ischaemic stroke has the potential to decrease mortality and morbidity, stroke burden and costs for the society as a whole.
The aim of cavotricuspid isthmus (CTI) dependent flutter ablation is the bidirectional conduction block of CTI. The probability of achieving a permanent bidirectional block at the CTI depends, mainly, on the ablation energy applied and the quality of the obtained lesion. Among the factors that determine the lesion's quality those which have the bigger impact are catheter stability, contact force, power and duration of energy application and the temperature reached at depth.This is a multicenter 1:1 randomized, blinded (open for the operator) study. Two CTI ablation strategies are compared: 1) conventional treatment branch which consists of individual 25-40 W applications of unlimited duration until achieving in each application the minimum value of one of the currently accepted and used lesion markers (Ablation Index >500 at the anterior half of the CTI and >400 at the posterior half with de CARTO 3 system; 2) experimental treatment branch consistent of CTI block using individual high power (90W) short duration (4 seconds) point-by-point applications. The main objective of this study is assessing the non-inferiority of the efficacy and safety of high-power short-duration ablation in patients undergoing typical atrial flutter ablation. Secondary objectives include the comparison of total radiofrequency time, number of applications, number of steam pops, percentage of reconnections, procedure duration, pain during the procedure and time to atrial flutter recurrence.
The goal of this retrospective registry is to evaluate the efficacy and safety of Refralon®, concentrate for solution for intravenous injection, as chemical cardioversion in patients with paroxysmal and persistent atrial fibrillation and flutter in routine clinical practice. The main questions it aims to answer are: - What is the incidence of sinus rhythm restoration within 6 hours in patients with paroxysmal atrial fibrillation (AF)/atrial flutter (AFL) after the first dose of Refralon®? - What is the incidence of sinus rhythm restoration within 24 hours in patients with persistent AF/AFL after the first dose of Refralon®?
Typical atrial flutter ablation involving forming a line of block across the cavotricuspid isthmus in the right atrium has become a commonly performed procedure and is considered a class I indicated procedure for patients who wish to pursue maintenance of sinus rhythm. The ablation generally involves 2-3 catheters and is typically performed through the femoral vein(s). After the ablation procedure, the patient is placed on bed rest for 4 hours, and typically discharged home the same day on oral anticoagulation. Catheter technology has improved over the past several years allowing for more rapid ablation with shorter procedure times. Ultrasound has also become more routinely used when obtaining venous access for the patient. To date, ablation of typical atrial flutter through the left or right arm has not been reported. Diagnostic electrophysiology studies have been performed through the arm and AV node ablation has also been reported from the cephalic, internal jugular, axillary and subclavian veins. The potential benefits include shorter recovery time, reduced risk of retroperitoneal bleed, and the avoidance of access complications from the groin. This study aims to evaluate the safety, feasibility, and efficacy of performing typical atrial flutter ablation through the arm. Specifically, the study will aim to: 1. Compare the recovery time immediately after the procedure using upper extremity access compared to the standard approach. 2. Compare the success rate of patients that undergo ablation of typical atrial flutter through the upper extremity venous system (experimental approach) to the standard approach (i.e., through the femoral vein(s). Success will be defined as ablation that leads to evidence for bidirectional block across the right atrial cavotricuspid isthmus. 3. Establish what the potential complications are from performing typical atrial flutter through the left or right arm. The left arm will be the preferred site for access because of less tortuosity to reach the heart. If one side cannot be accessed the alternate arm will be used, but will be left to the discretion of the operator. The operator will have the discretion to switch to a femoral approach at any time. 4. Compare the complication rates of the experimental approach evaluated by the inability to access the vein, and other complications (e.g., bleeding, vein thrombosis, heart perforation) from accessing the vein in the arm to the complication rates of the standard approach. 5. Compare long term (i.e., 1 month and 1 year) success of the experimental approach vs. the standard approach as assessed by maintenance of normal sinus rhythm, without recurrent typical right atrial flutter with in person visits and phone call or chart evaluations. 6. Compare pain severity of the insertion site between the experimental and standard approaches.
