New treatment option for Coronary Artery Stenosis
Official title Complete Functional Assessment of Intermediate Coronary Artery Stenosis Before and After Transcatheter Aortic Valve Implantation (TAVI) in Patients With Severe Symptomatic Aortic Valve Stenosis
ClinicalTrials.gov ID: NCT05133843
What this study is testing
- What it's testing
- The purpose of the current study is to assess complete coronary physiology (FFR, RFR, CFR, IMR, and CT-FFR) in TAVI candidates with intermediate coronary artery stenosis before and 6 months after TAVI. This aims to determine how TAVI affects coronary blood flow and coronary microcirculatory function after longer-term follow-up, and how these effects influence FFR and RFR values.
