Filter by:In this randomized controlled trial, amount of sedation exposure and patient satisfaction is evaluated in patients undergoing catheter ablation for rhythm disorders via an audiovisual distraction. Patients are randomized into intervention group (adiovisual distraction) or controll (no intervention).
To demonstrate the value and benefits of BIOTRONIK's exclusive DX technology in assessing the incidence of supraventricular arrhythmias, mainly atrial fibrillation (AF), in patients with an indication for single chamber ICDs. Effects of the DX technology on related events, such as delivery of therapies and medical management, including eventual complications. Extended benefits offered by DX devices when associated with daily remote monitoring, by means of BIOTRONIK's Home Monitoring Service Center (HMSC).
The purpose of this study is to evaluate differences between single-shot EQUAL ropivacaine doses of the serratus anterior plane block (SAPB) or erector spinae plane block (ESPB) injection, when used as adjuvant to treat postoperative pain, after one-stage unilateral hybrid arrhythmia (atrial fibrillation, ventricular tachycardia, inappropriate sinus node tachycardia) ablation surgery. The primary outcomes are to evaluate block placement efficacy in the hybrid surgery setting (total time to block placement in seconds, time to visualization of location of injection in seconds, adequacy of ropivacaine spread) by picturing and worst numerical scale pain at rest or moving, using a visual analog pain scale from 0= no pain to 10= maximal pain, in the first 12 hours after admission to the post-anaesthesia care unit. Secondary outcomes aim to evaluate to investigate pain location, additional analgesic consumption and requests, ease of breathing, breathing quality, sleeping quality and quantity, duration of hospitalisation, and general level of satisfaction.
The study will include patients scheduled for transvenous pacemaker- or implantable defibrillator surgery, where venous access is necessary for lead implantation. A 1:1 randomization will be performed to either standard access (at the discretion of the surgeon) or ultrasound-guided using a wireless vascular transducer (Siemens Freestyle). Primary outcome is mean time to vascular access. In addition, success rate, complication rate and total procedure time will be measured.
The overall aim of this study is to improve our understanding of the effects of the build-up of amyloid deposits in the heart, in particular, our understanding of the risk of abnormal heart beats, or rhythms, associated with people with cardiac (heart) amyloidosis. Symptoms such as palpitations (fast, strong or irregular heart beat) and blackouts are common in people with cardiac amyloidosis, but there is not enough information on what causes this. At present, there is also not enough information on when they occur, how often they happen, and which patients are at risk of having serious, life-threatening types of abnormal heart rhythms. Some of these abnormal heart rhythms can be treated with medicine; others need electronic devices (e.g. pacemakers) implanted or inserted in the heart to prevent serious harm. The information on when is the best time to implant these life-saving devices remains limited. In this study, a small device known as an implantable loop recorder (ILR) will be implanted under the skin on the chest wall to continuously monitor participants' heart rhythm. This will help us answer some of the questions about what causes the abnormal heart rhythms, when they happen, and which patients are particularly likely to have them. Furthermore, it may help us to identify earlier, rather than later, those who are at risk of developing abnormal heart rhythms. This may lead to improvements in the care of people with cardiac amyloidosis in the future. Participants may not directly benefit from taking part in this study; however, there is a chance that the ILR may reveal heart rhythm abnormalities in some participants which might not be picked up otherwise, and so may lead to a change in their treatment.

This clinical investigation evaluates the feasibility of the Rodeo Micro Mapping Catheter in combination with cryoablation ssystem (sclerotherapy of muscle tissue of the heart by freezing) in patients with atrial fibrillation (permanent atrial fibrillation excepted). Further aims of this study are the evaluation of safety of the device and average procedure and fluoroscopy times.
New-onset supraventricular arrhythmia (NOSVA) is reported in 40 % of patients with septic shock and is associated with hemodynamic alterations and mortality. The lack of consensus regarding best practices for the management of NOSVA in this setting has led to major variations in practice patterns. Observational studies reported three usual strategies: (i) heart rate control (hereafter rate control) with the use of antiarrhythmic drugs, essentially based on low dose of amiodarone, (ii) rhythm control with the use of antiarrhythmic drugs, essentially based on high dose of amiodarone, and electrical cardioversionand (iii) modifiable NOSVA risk factors control (hereafter risk control) without using antiarrhythmic drugs. Risk control would minimize adverse events of antiarrhythmic drugs. Rhythm control would rapidly improve haemodynamics via restoring diastole and decreasing cardiac metabolic demand, while minimizing exposure to anticoagulation. Rate control, would limit potential adverse events of high dose of amiodarone and of electrical cardioversion (only in patients intubated on mechanical ventilation), while controlling haemodynamics. Therefore, it seems important to compare these three strategies. Our hypothesis is dual: first, that rate control and rhythm control each improve hemodynamics with in fine a decreased mortality, as compared to a risk control; second, that rhythm control outperforms rate control in this setting. This is a multicenter, parallel-group, open-label, randomized controlled superiority trial to compare the effectiveness and safety of these three strategies (risk control, rate control and rhythm control) for NOSVA during septic shock.
This is a prospective, single-center, phase II trial that will be monitoring the safety and efficacy of using stereotactic ablative radiotherapy (SBRT) to treat patients with a medical condition affecting heart rate and rhythm (refractory arrhythmias) within the University Health Network (Princess Margaret Cancer Centre and Toronto General Hospital). The primary objective will be to prospectively monitor patient cardiac outcomes following SBRT.
The study will examine the presence of cardiac arrhythmias in patients receiving hemodialysis and the role of diabetes, hypoglycemia and parameters related to uremia and the dialysis procedure. The study is designed as a prospective cohort study with 18 months follow-up. 70 patients receiving chronic hemodialysis will be recruited and equipped with implantable loop recorders (ILR): 35 patients with diabetes and 35 patients without diabetes. Data collection during the follow-up includes continuous monitoring of the heart rhythm by the ILR for the entire follow-up period, continuous glucose monitoring for 10 days every second month, and monthly collection of blood samples and dialytic parameters.
