Filter by:Atrial Fibrillation (AF) is a heart rhythm disturbance that affects over a million people in North America. AF can cause strokes, heart failure, poor quality of life and may lead to premature death. Catheter ablation has been shown to be superior to medications for symptoms, prevention of stroke and heart failure. AF recurrence is a problem after catheter ablation. Our research has found that in most cases AF recurrence occurs because the catheter procedure was ineffective. The objective of our clinical trial is to find out if a new method of performing the catheter procedure will be more effective in preventing AF recurrence compared to the current standard of care ablation procedure. Subjects will be randomly allocated to undergo either the standard of care ablation, or the novel patient tailored ablation. The novel method aims to understand the unique factors responsible for AF in each individual and uses this information to perform a patient-tailored catheter ablation procedure. This is expected to improve the results of AF ablation. The effectiveness and safety of the ablation procedure will be specifically evaluated in women to understand the effect of sex on AF ablation.
Radiofrequency ablation (RFA) is a standard treatment option for cavotricuspid isthmus (CTI) dependent atrial flutter. We plan to perform a randomized prospective trial comparing the efficacy of contact force (CF) guided CTI ablation against catheter ablation with the operator blinded to contact force parameters.
This study is an observational study designed to determine the extent of gastrointestinal (GI) post-procedure complications after Radiofrequency Catheter Ablation (RFCA) for atrial fibrillation (AF). This exploratory study will evaluate patient symptoms prior to the RFCA procedure, at 1 month post RFCA procedure, and at 3 months post RFCA procedure, through the administration of a questionnaire. The purpose of this study is to determine if vagus nerve injury resulting from RFCA for AF increases the risk of post-procedure GI complications that may present as temporary or permanent symptoms.
The aim of this prospective randomized clinical trial was to evaluate the early and late outcome following left atrial radiofrequency ablation during MV surgery for the treatment of continuous atrial fibrillation and to assess the functional effects of restoration of sinus rhythm.
Radiofrequency ablation is a procedure done in the Catheterization Laboratory to help correct specific problems that cause the heart to beat faster than it should. Quality of life includes the physical as well as the emotional aspects of a patient. Doctors have always tried to take care of a medical problem with minimal physical and emotional risk. It is assumed that once the medical problem is fixed, the patient will have an improved quality of life. To know if this assumption is true, the investigators are asking children scheduled for this procedure, along with their family, to answer questions before the ablation, then answer the same questions 5-6 months after the ablation.
