Ambulatory Electrocardiographic Monitoring for the Detection of High-Degree Atrio-Ventricular Block in Patients With New-onset PeRsistent LEft Bundle Branch Block After Transcatheter Aortic Valve Implantation. The "MARE" Study
Trial Parameters
Brief Summary
The purpose of this study is to determine the incidence and predictors of high degree or complete atrioventricular block (AVB) (paroxysmal or persistent) in patients with new-onset persistent left bundle branch block (NOP-LBBB) following transcatheter aortic valve implantation (TAVI) and to evaluate the usefulness of the Reveal LINQ® insertable Cardiac Monitor (ICM) (Medtronic, Inc., Minneapolis, USA) for the detection of significant arrhythmias in patients with NOP-LBBB following TAVI.
Eligibility Criteria
Inclusion Criteria: -Patients undergoing TAVI with either balloon or self-expandable valves who develop new-onset LBBB persistent at hospital discharge, at least 3 days after the procedure Exclusion Criteria: * Failure to provide informed consent * Baseline pacemaker/defibrillator or pacemaker/defibrillator implanted during the hospitalization period following the TAVI procedure * Pre-existing complete LBBB * Patients with a life-expectancy of less than 2 years
