Filter by:The goal of this observational study is to evaluate the clinical characteristics of patients undergoing permanent cardiac pacing and to compare procedural efficacy and safety of different implantation approaches in the clinical practice of the participating centres. The contribution of non-fluoroscopic anatomical and electrophysiological reconstruction systems to device implantation procedures will also be evaluated. Participants [patients over 18 years old with an indication to receive a definitive pacemaker/intracardiac defibrillator implant] will receive a permanent cardiac pacing implant as requested according to European Society of Cardiology (ESC) guidelines; the investigators will evaluate procedural efficacy and safety of different implantation approaches.
This is a multicenter prospective randomized blind controlled trial with a sham procedure group of the efficacy and safety of cardioneuroablation as a method of treating symptomatic bradycardia without a permanent pacemaker implantation
This is a prospective clinical observation and registration study. The investigator aimed to evaluate the efficacy and safety of cardiac denervation ablation as a treatment strategy for severe sinus bradycardia.
This study is a first-in-human, prospective, multi-center, pre-market single-arm clinical trial to evaluate the Future Cardia™ ICM.
The purpose of this coverage with evidence development (CED) study is to evaluate complications and long-term health outcomes of the single-chamber Aveir Atrial Leadless Pacemaker device (aka Aveir™ AR LP system).
A prospective, multinational, randomized, double-blind, clinical trial evaluating the safety and effectiveness of a novel atrioventricular interval modulation (AVIM) algorithm downloaded into a previously implanted dual-chamber Medtronic Astra/Azure DR MRI IPG.
Guidelines for patients having first-time implants advocate that even when heart function is only mildly impaired, modern pacing approaches should be utilised to avoid the potentially damaging effects of RV pacing to preventing symptoms from pacing induced or worsened cardiomyopathy. However, once a traditional (RV) pacemaker is implanted, development of impaired heart function does not prompt a device upgrade. Even at the end of battery life, physicians simply replace it like-for-like. This trial tests whether such patients have better symptoms and quality of life if changed to a modern physiological pacing strategy from the traditional RV pacing approach. In this crossover trial, participants will be upgraded to a physiological pacing strategy. After their procedure, they will have a one-month run-in period to recover from the procedure (their pacemaker will be programmed to continued RV pacing). They will be have 2 one-month blinded time periods, randomised to physiological pacing or right ventricular pacing alternately. They will subsequently undergo two six-month blinded randomised time periods. Patients will document symptoms monthly on a mobile phone application or computer. At the end of each time period, they will have measurements of heart function, a walking test and quality-of-life questionnaires including the SF-36 questionnaire. The investigators hypothesise that upgrading to physiological pacing strategies will improve patients' quality of life.
The purpose of the China CIED 3.0T MRI Performance Study is to confirm safety of SureScan CIED in the clinical 3.0T MRI environment when subjects receive MRI scans. ll subjects will have required follow-up visits at baseline, MRI visit, 1-month post-MRI. The MRI scans will occur at the MRI visit. The MRI scan region will be determined by investigator according to the subject's clinical condition.
The study is designed as an open-label, prospective, international, multicenter, non-randomized study to determine safety and product performance of the CE-marked Amvia/Solvia pacemaker family, including the aATP, CRT AutoAdapt and Early Check features in the setting of a post-market clinical follow-up study.
The purpose of this post-approval study is to evaluate the long-term safety of the dual-chamber Aveir DR leadless pacemaker using real-world evidence methods.
