Access is a data collection study for patients who have been diagnosed with Aortic Stenosis.

Patients who qualify for this study had a procedure called Transcatheter Aortic Valve Replacement (TAVR). TAVR is intended to implant a new valve in the heart without using open heart surgery. The purpose of this study is to collect additional data points on patients whose doctor chose to use the subclavian or axillary access points.
