Novel Anatomic Predictors of New Persistent Left Bundle Branch Block after Evolut Transcatheter Aortic Valve Implantation

Transcatheter aortic valve implantation(TAVI) is now approved in the United States in patients with symptomatic severe aortic stenosis regardless of surgical risks.1,2 While increasing operator experience, better patient selection and newer-generation transcatheter heart valves(THV) have helped optimize TAVI outcomes,3,4 conduction disturbances requiring permanent pacemaker(PPM) and new persistent left bundle branch block(NP-LBBB) remain unsolved issues.1,2 Recent data showed that NP-LBBB after TAVI could impact mortality and rehospitalization, PPM implantation and adverse left ventricular function recovery.
