Aortic Valve Disease Clinical Trial

Official title:
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

Clinical Trial 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.

Clinical Trial Description

This is a prospective observational study including patients undergoing TAVI with either self- or balloon-expandable valves. After the procedure, patients will be on ECG monitoring during the hospitalization period (or at least 72 hours), and an ECG will be performed daily until hospital discharge in all patients. Patients with new-onset persistent LBBB at hospital discharge (new-onset LBBB of a duration of at least 48 h which persists at hospital discharge, at least 3 days and up to 15 days after the procedure) will receive an implantable loop recorder Reveal ICM LINQ®, which will be implanted subcutaneously to record adequate QRS complexes and P waves. The patients will be followed in outpatient clinic visits at 1, 12, 24 and 36 months after TAVR, or if symptoms suggestive of cardiac origin or relevant arrhythmic events occur. The device will be manually interrogated in each visit. Phone contacts will be also carried out every three months. ;
