The purpose of this study is to show that Electrocardiogram Ambulatory Monitoring-guided strategy is superior to ElectroPhysiological Study on the rate of alive patients with an appropriate Pacemaker implantation/non-implantation, at 12 months after randomization, in patients with New Onset Persistent Left Bundle Branch Block after Transcatheter Aortic Valve Implantation.
Presenting with New Onset Persistent Left Bundle Branch Block, defined as a new Left Bundle Branch Block >150 ms that persists at least two days after Transcatheter Aortic Valve Implantation and is stable
With an anticipated life expectancy >1 year
Who consent to participate to the study
Documented high grade Atrio Ventricular block (Atrio Ventricular block of a degree higher than Mobitz I)
Persistent PR interval prolongation > 240 ms
Occurrence of syncope or sudden cardiac death,
Identification of any indisputable criteria for Pacemaker implantation
