Filter by:Background: Atypical atrial flutter (AAF) is an increasingly relevant clinical problem. Despite advancements in mapping and ablation techniques, the general management of these patients remain challenging especially when mapping cannot be performed during ongoing arrhythmia. There are no data whether induction of AAF is a feasible approach in these cases. Methods: The investigators retrospectively analyzed patients who underwent catheter ablation of AAF and compared procedural results between patients with ongoing tachycardia when starting the procedure and patients with induced AAF. For this retrospective study, the investigators analyzed patients undergoing ablation of AAF between April 2018 and January 2021 that were identified from the ablation database at the West German Heart and Vascular Center, Essen. All patients were followed up in the outpatient clinic as part of the clinical standard routine or contacted by telephone to assess the occurrence of clinical recurrence of any arrhythmia. In case the documentation was not performed at the institution, relevant documents and ECGs were requested and reviewed. This single-center cohort study was conducted at the University Hospital Essen, Germany, in accordance with the Declaration of Helsinki and its amendments and was approved by the institutional review board of the University of Essen (number 21-10341-BO). Written informed consent was obtained from all study participants. The primary study endpoint was to evaluate the outcome of patients with induced AAF in comparison to patients with ongoing AAF when starting the procedure. Furthermore, the investigators analyzed the type of recurrence during follow-up as well as the occurrence and results of repeat ablations at the institution. The investigators also evaluated if the recurrent AAF form was the same or de-novo compared to the AAF during previous procedure.
This study is a post-market clinical follow-up (PMCF) study to identify and evaluate residual risks associated with the use of the BIOMONITOR III and BIOMONITOR IIIm that are discovered or remain even after risk analysis, risk mitigation and successful conformity assessment. Furthermore, this study will also provide additional data as required by regulatory authorities outside of the CE-region.
Post-Market Clinical Follow-up of the new Cor Family ICDs/CRT-Ds (Acticor, Rivacor) and the new Plexa ProMRI S DX right ventricular lead to provide post-market data and supporting evidence for the clinical safety and performance of the devices.
The objective of the study is to confirm the safety and efficacy of the BIOMONITOR III system. Furthermore, the insertion procedure, the use and handling of the incision and insertion tools and the sensing quality of the BIOMONITOR III will be assessed.
Recorded cutaneous ECG containing arrhythmia events are separately analysed by an expert Electrophysiologist and the ISSD detection algorithm, to allow assessment of the correct detection of tachyarrhythmia events and discrimination of supra-ventricular arrhythmia of the algorithm,m compared to the expert.
Following product approval, confirmation of appropriate VF episode detection after MRI exposure of the ProMRI ICD/CRT-D systems and to evaluate left ventricular pacing threshold changes post-MRI.
Following product approval, further confirmation of the MR Conditional Tachyarrhythmia Therapy Systems sensing and detection performance post MRI exposure will be obtained by actively monitoring de-identified device data obtained through the Medtronic CareLink® Network.
Post-Market Clinical Follow-up of the new Ilivia ICD Family and the new Plexa right ventricular lead to fulfill requirements by the notified body and to support regulatory approval outside of the CE region
The objective of the study is to confirm safety and efficacy of the BioMonitor 2. The data is collected to support the regulatory approval of this product in countries outside the CE region.
The objective of this study is to confirm the safety and efficacy of the new Sentus OTW QP LV lead and Iperia ICD family. The study focuses on the safety and efficacy of the QP device system.
