Comparison between the SAPIEN S3 and the SAPIEN XT transcatheter heart valves: A single-center experience

Abstract

The S3-THV is associated to lower rates of major vascular complications and PVR but higher rates of new pacemaker compared to the XT-THV. Sub-optimal visualization of the S3-THV in relation to the aortic valvular complex during deployment is a predictor of new permanent pacemaker.
