Avoiding S3 Valve Over-Sizing by Deployment Balloon Over-Filling: Impact on Rates of Permanent Pacemaker and Other Procedural Complications During TAVR.

OBJECTIVES: Patients with annular areas just above nominal S3 valve areas are at increased risk of over-sizing if a larger valve is implanted. We therefore evaluated the rate of permanent pacemaker (PPM) implantation associated with avoiding over-sizing by selective deployment balloon over-filling during transcatheter aortic valve replacement (TAVR) with the Sapien 3 (S3) valve. METHODS: We included consecutive patients treated with the S3 …
