Filter by:Patients with atrial fibrillation (AF) who have had a prior stroke are at very high risk of recurrent ischemic stroke. About 40% of these strokes are due to large emboli which result in large cerebral vessel occlusion (LVO). This randomized control trial aims to address this unmet need by testing whether use of bilateral carotid filter implants in addition to OAC will reduce the risk of stroke in AF patients with recent (e.g. within 12 months) ischemic stroke vs. only OAC.
The goal of this clinical trial is to compare the use of long-term vs. shorter-term heart monitoring to detect atrial fibrillation after stroke. Patients will be implanted with a loop recorder and will have study follow-up at 3-, 6- an 12-months after implantation. The investigators will evaluate 24 patients, between the 3 centers, in the same way the investigators plan to evaluate a larger number of participants (>1000) in a future study. This will allow us to learn if such a study is possible, identify potential implementation challenges, and develop strategies to overcome those difficulties.
The aim of the study is to find factors associated with sinus rhythm maintenance after catheter ablation for atrial fibrillation.
PeQasus is a worldwide, retrospective, multicenter analysis focusing on QDOT based PVI. Data of at least 300 patients with QDOT based PVI will be collected. All data will be evaluated after anonymization. Primary endoints are efficacy and safety.
The goal of this randomized double blind controlled trial is to learn about the effects of calcium when it is given prior to diltiazem for patients with atrial fibrillation ( a type of irregular heart beat) who have rapid ventricular response ( a pulse over 100 beats per minute). Normally diltiazem 0.25mg/kg (max 20mg) is given to slow the heart rate. We will give Placebo versus Calcium Gluconate 2gm given prior to diltiazem. The main questions it aims to answer are: - Does calcium decrease the incidence of low blood pressure (a side effect of diltiazem)? - How does calcium effect the action of diltiazem? Does it interfere with the desired decrease in heart rate? Participants will receive either placebo or calcium immediately prior to the administration of diltiazem. Their blood pressure and pulse will be measured: - prior to study drug administration - post study drug and prior to diltiazem administration - 3 minutes post start of diltiazem - 5 minutes post start of diltiazem - 10 minutes post start of diltiazem - 20 minutes post start of diltiazem - 30 minutes post start of diltiazem Researchers will compare the placebo group to the calcium group to see if there is a difference in the blood pressure and pulse.
This is a three-arm, single-blinded, randomized, sham-controlled, nonsignificant risk study to assess the feasibility of reducing Atrial Fibrillation burden with peripheral nerve stimulation. The three arms include treatment with a wrist-worn neuromodulation ("wrist device"), treatment with an ear-worn neuromodulation device ("ear device") and sham stimulation with wrist-worn device that does not actually deliver stimulation ("sham device"). ECG patches will be worn on the chest to measure AF episode onset and duration ("ECG Patch"). Additionally, a wrist-worn monitoring device will be used for the measurement of heart rate (HR), heart rate variability (HRV), and other biomarkers ("Cardiac Measurement Device (CMD)"). Finally, subjects will track AF episode onset, duration, and symptom type in an AF diary.
The principal purpose of this investigator-initiated trial is to study the use of the CardiaMend device soaked in the anti-arrhythmic drug amiodarone, and how it may decrease the development of atrial fibrillation in patients that have undergone a coronary artery bypass surgery, or isolated valve surgery.
From January 2023 to December 2025, 300 elderly patients with nonvalvular atrial fibrillation in Drum Tower Hospital Affiliated to Medical Scholl of Nanjing University will be enrolled to compare the efficacy and safety of rivaroxaban-H, rivaroxaban-M and rivaroxaban-L dose in elderly patients after 24-month follow-up.
This study is aimed to validate the existing stroke risk stratification model for patients with atrial fibrillation (AF) (CHA2DS2-VASc Score, CHADS2 Score, ATRIA score, ABC score, etc.) and establish a new stroke risk assessment model using a nationwide AF -specific registry in China.
Esophageal temperature monitoring during certain cardiac ablation procedures, such as left cardiac ablation procedures, is an accepted and important part of many clinical procedures today. The primary risk of the temperature monitoring devices relates to performance. Inadequate temperature recording, inadequate capture of peak temperatures or slow temperature response times can lead to inadequate monitoring of the ablation procedure. The E-SAFE Esophageal Temperature Probe (E-SAFE) is a unique combination of currently available technologies that improves the accuracy of esophageal temperature monitoring. The incremental improvements of the E-SAFE device provide accurate, precise and fast measurement of esophageal temperature during cardiac ablation procedures. Accurate esophageal temperature monitoring must be accomplished safely; therefore, the rationale of this pivotal clinical investigation is to evaluate the safety and clinical performance of the E-SAFE device in monitoring esophageal temperature during AF ablation procedures. Esophageal temperature monitoring should be used together with all standard clinical practices for esophageal protection during cardiac ablation procedures.
