Filter by:Heart Failure (HF) with systolic dysfunction is associated with a poor prognosis in the long term despite the use of many effective drug treatment in reducing morbidity and mortality. In this context, cardiac resynchronization (CR), either alone or combined with a defibrillator function, has improved by about 30 to 40% of morbidity and mortality in this population of patients with heart failure. The information on the CR are now well established for patients with stage III-IV NYHA (New York Heart Association), with systolic dysfunction (EF ≤ 35%), presence of left bundle branch block wide (≥ 120 ms) and when medical treatment is optimal. As a result, the number of implanted devices continue to grow even if the implant procedures of cardiac resynchronization devices (CRD) are long, difficult and associated with significant complications with a risk of reoperation estimated between 10 and 15% . One of the most feared during implantation devices stimulation or defibrillation risk is represented by the risk of infection that will lead inevitably to explantation of the device. Despite the use of several preventive measures, including the use of an antiseptic shower, a local preparation for alcoholic povidone iodine (API) (PVPI 5% ethanol + 70%) and antibiotic prophylaxis clinical studies the most recent have clearly demonstrated that the risk of infection was associated with the duration of the intervention and was higher for procedures CR, it is noted in 2.4% in the short term and would be close to 3 to 4% in the medium term. Infections of implantable devices are associated with a poor prognosis, even in an excess mortality. It has been shown that the majority of infections may be linked to local contamination during surgery reinforcing the idea that prevention is mainly based on local measures and the reduction of operating time.
The aim of the present study is to compare the antiarrhythmic and myocardial protective effect between lidocaine, dexmedetomidine, and their combined infusion in subjects undergoing coronary artery bypass graft.
The goal of the study is to compare whether a center-wide policy of incremental antibiotic therapy will reduce CIED infection rate compared to a policy of conventional antibiotic prophylaxis in high-risk patients undergoing arrhythmia device procedures. All antibiotics used are approved for use and readily available.
The goal of the pilot study is to compare whether a centre-wide policy of incremental antibiotic therapy will reduce pacemaker infection compared to a policy of conventional antibiotic prophylaxis in high-risk patients undergoing arrhythmia device procedures. This pilot study will provide feasibility information for a larger cluster randomized crossover design (CRCD).
The purpose of this study is to compare the two options for management of ICDs (internal cardioverter defibrillators) in patients undergoing procedures with electrocautery: (1) programming ICD therapies "off," or (2) use of a magnet to suspend ICD therapies By comparing these two techniques the investigators hope to demonstrate the efficiency of using an ICD magnet protocol during perioperative management of patients undergoing electrocautery procedures. Secondary purposes are to gain further information on health care resources, incidence of EMI, handoff communications and to document lack of adverse events in either group. Primary objective will be: ICD therapy "off times" will be less with the use of a magnet protocol compared to an "off-on" protocol. Secondary objectives will be: (1) Healthcare resources (time and costs of skilled personnel) will be less using a magnet protocol compared to an off-on protocol, and (2) there will be no difference between adverse events in the magnet protocol compared to an off-on protocol. The incidence of EMI and number of handoff communications will be documented. The investigators hypothesis is that the number of minutes with ICD therapies "off" will be significantly less with magnet use. The investigators also expect health care resources to be less with magnet use compared to reprogramming.
The purpose of this study is to compare rotational angiography (3DATG technology)intra-procedure (during the ablation procedure) with CT (x-ray) pre-procedure (before the ablation procedure) fusion to create an anatomical picture of a heart to help adequately guide an ablation procedure for patients with arrhythmias.
The purpose of this study is to learn if combination therapy with amiodarone and ranolazine (an approved drug for chest pain) can help prevent arrhythmias.

The purpose of this study is to demonstrate the safety and effectiveness of the THERMOCOOL® SMARTTOUCH™ Catheters with Contact Force Sensing Capability in the treatment of drug refractory symptomatic paroxysmal Atrial Fibrillation (AF) during standard electrophysiology mapping and RF procedures.
Safety and efficacy in radiofrequency (RF) or cryoballoon atrial fibrillation (AF) ablation will be investigated in a cohort study design in experienced electrophysiologic (EP) centers analyzing propensity-matched cohorts.
