Evaluation of the CIRCA Monitoring System in Prevention of Esophageal Lesions Following RFCA

Dr. Gregory Feld, M.D. is conducting a research study to find out more about the short-term effects on the esophagus of left atrial ablation (guided by Circa esophageal temperature monitoring system). The financial supporter of this study is Circa Scientific, LLC. When the investigators perform a radiofrequency catheter ablation (RFCA) ...

Phase N/A

Comparison of High Versus Escalating Shocks in Cardioverting Atrial Fibrillation

The optimal energy selection for biphasic direct current (DC) cardioversion of atrial fibrillation is unknown. The energy delivered should be sufficient to achieve prompt cardioversion but without the risk of inducing any potential injury e.g. skin burns, myocardial stunning or post-cardioversion arrhythmias. The use of an escalating protocol, with a ...

Phase N/A

Systematic Assessment and Targeted Improvement of Services Following Yearlong Surgical Outcomes Surveys

The overarching purpose of SATISFY-SOS is to implement a rigorous process to assess short-term and intermediate-term outcomes of surgical and procedural patients who receive anesthesia services at Barnes-Jewish Hospital facilities, located in St. Louis, Missouri. Specifically, patients will be followed for major morbidity events, for mortality, and for quality of ...

Phase N/A

Clinical Investigation of the VytronUS Ablation System for Treatment of Symptomatic Drug-refractory Paroxysmal Atrial Fibrillation

Patients undergoing elective catheter ablation for symptomatic PAF who are refractory or intolerant to at least one antiarrhythmic drug (Class I-IV) will be screened for enrollment. Patients who meet the study entry criteria and sign the patient informed consent form will be enrolled and treated consistent with the 2012 Heart ...

Efficacy of Delayed Enhancement MRI-Guided Ablation vs Conventional Catheter Ablation of Atrial Fibrillation

BACKGROUND AND INTRODUCTION: Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting millions of people in the US and around the world. Treating AF continues to be a challenge. Over the last 15 years, catheter based AF ablation procedure has been widely adopted. Approximately 50% of patients treated with ...

Phase N/A

Correlation of the Arrhythmia Mechanism and Substrate to Ablate Persistent Atrial Fibrillation Study

Pulmonary vein isolation catheter ablation for the treatment of persistent AF (PeAF)or longstanding persistent AF is associated with success rates of 40-50% at one year. Experimental models have shown that AF results in progressive structural changes due to electrical atrial remodeling, where AF burden correlates with atrial fibrosis. The optimal ...

Phase N/A

Pharmacogenetic Study of Antiarrhythmic Drugs for Atrial Fibrillation

1.0 Background While atrial fibrillation (AF) is the most common sustained cardiac arrhythmia requiring therapy, it is also associated with increased risk of stroke, heart failure, myocardial infarction, dementia, and death. The number of Americans affected with AF is expected to surge to nearly 16 million by the year 2050. ...

Left Atrial Appendage Occlusion Guided by 3D Printing

The 3D printing has modified the LAAC practices with a preoperative time allowing an optimal preparation of the prosthesis. This technique is now used in several surgical centers and prospective evaluation of the practice is necessary. The objective of our research is to demonstrate the reduction of the operating time ...

Phase N/A

Multimodality Prediction of Success of Atrial Fibrillation Rhythm Control Strategy

In this study the investigators aim to build a model to predict the maintenance of sinus rhythm (SR) after successful direct current cardioversion (DCC) incorporating standard predictors such as echocardiographic parameters, clinical parameter and 12-lead ECG parameters and new parameters, including 17-lead ECG, Oesophageal-ECG and single nucleotide polymorphisms (SNPs). Using ...

Phase N/A

Frontal Cognitive Control Functions Before and After Percutaneous Catheter Procedures in Treatment of Atrial Fibrillation

Atrial fibrillation is a common arrythmia. It is an independent risk factor for stroke. There for anticoagulation therapy is used for atrial fibrillation patients. Alternatively, left atrial appendix closure can be used, if the risk for bleeding complications is deemed greater than the possible antithrombotic benefit of anticoagulation medication. Up ...
