Filter by:This is a prospective safety and feasibility study to evaluate the safety of the FieldForce™ Ablation system in patients with ventricular arrhythmia divided into two groups: VT (VCAS-I) and frequent premature ventricular complex (VCAS-II).
The purpose of this study is to determine whether the use of domperidone is associated with an increased risk of serious cardiac events among postpartum women in the six months following delivery. The hypothesis is that the use of domperidone will be associated with an increased risk of serious cardiac events among postpartum women. The investigators will carry out separate population-based cohort studies using health care databases in five Canadian provinces. Women with live births will be eligible to enter the cohort. We will identify all women who start domperidone during the six months following delivery and match them to similar women who do not start domperidone, with all included women followed until the occurrence of an adverse cardiac event or for up to six months after delivery. The results from the separate sites will be combined to provide an overall assessment of the risk of serious cardiac events in users of domperidone.
The study evaluates whether catheter based radiofrequency ablation is superior to optimized antiarrhythmic medical therapy in preventing ventricular tachyarrhythmia relapses in patients with ischemic heart disease and implantable cardioverter defibrillator.
The purpose of the NORDIC ICD study is to evaluate whether ICD implantation without intra-operative DF testing is non-inferior to ICD implantation with intra-operative DF testing regarding the efficacy of the first ICD shock for the treatment of true spontaneous ventricular tachyarrhythmias.
Patients with implantable cardioverter defibrillators (ICDs) should undergo regular device follow-ups every 3 months, to verify proper ICD function. However, many follow-ups are uneventful, revealing no relevant changes related to the implanted device and in the patient's diagnostic and therapeutic status. For time and economic reasons, longer follow-up intervals are frequently used although they are not according to recommendations. This may increase the delay in detection of relevant changes in the disease and in deviations from optimal ICD therapy in the individual patients. In the newest ICDs, the essential parameters reflecting safety and appropriateness of ICD therapy (threshold, impedance, intracardiac electrogram, etc.) are transmitted via Home Monitoring on a daily basis, to an internet platform accessible by the attending physician. In the present study, the investigators evaluate safety and efficacy of 12-month follow-up intervals in ICDs with Home Monitoring capability, as compared with conventional 3-month follow-up scheme.
