Abstract
- Background As younger patients are being considered for transcatheter aortic valve implantation (TAVI), the assessment and treatment of concomitant coronary artery disease is taking on increased importance. Methods and Results Thirteen contemporary lower‐risk patients with TAVI with severe aortic stenosis (AS) and moderate‐severe coronary lesions were included. Patients underwent assessment of coronary hemodynamics in the presence of severe AS (pre‐TAVI), in the absence of severe AS (immediately post‐TAVI), and at longer‐term follow‐up (6 months post‐TAVI). Fractional flow reserve decreased from 0.85 (0.76–0.88) pre‐TAVI to 0.79 (0.74–0.83) post‐TAVI, and then to 0.71 (0.65–0.77) at 6‐month follow‐up (P
