Treatment Registry of Arrhythmias, Complications and Electrocardiograms in Arrhythmogenic CardioMyopathies

TRACE-ACM is a multicenter, retrospective, observational study of patients with arrhythmogenic cardiomyopathy who received an implantable cardioverter-defibrillator (ICD) and had documented ventricular tachyarrhythmias. The study aims to describe the prevalence and type of ICD-related complications, characterize ventricular arrhythmias documented by ICD electrograms and/or ECG recordings, and explore associations between clinical, device-related, and treatment-related factors and arrhythmic outcomes.

Perioperative Management Evaluation in Patients With CIED

Background: Recommendations for peri-operative management in patients with implanted cardiac electronic devices (CIED) are often based on older data from case reports and small collectives. Objective: To evaluate the peri-operative management and outcome of patients with implanted CIED undergoing non-CIED related surgery or catheter-interventional procedures in clinical routine. Study design: bi-center, non-randomized, observational registry, retrospective data-collection, on-going prospective patient enrollment, descriptive statistics Primary endpoint: number and type of peri-operative adverse device related events (ADE) Secondary endpoints: pre-interventional data (patient characteristics, data from CIED interrogation); peri-interventional data (type of surgery/intervention, anesthesiology techniques, any AE), postinterventional data (data from post-interventional CIED interrogation, need for reprogramming / device revision). Inclusion criteria: implanted CIED, non-CIED related surgical or catheter-based intervention, peri-procedural CIED interrogation, age \>18 years Exclusion criteria: no implanted CIED, no data from any peri-procedural CIED interrogation available Patient enrollment: retrospectively beginning from 2008, further on-going prospective inclusion Sample size: For the observational study, there is no pre-specified sample size. Data from more than 500 patients undergoing \> 700 interventions are expected.
