Optimal Timing of Transcatheter Aortic Valve Implantation and Percutaneous Coronary Intervention - The TAVI PCI Trial

The primary objective of this study is to compare, in patients with severe aortic stenosis and concomitant coronary artery disease accepted for transcatheter aortic valve implantation (TAVI) and percutaneous coronary intervention (PCI) by the multidisciplinary Heart Team, the safety and efficacy of angiography-guided complete revascularization performed after (within 1-45 days) with angiography-guided complete revascularization performed before (within 1-45 days) TAVI using the Edwards SAPIEN Transcatheter Heart Valve®.

The prevalence of coronary artery disease in patients with severe aortic stenosis is high. About 30-60% of patients undergoing TAVI exhibit coexisting coronary artery disease. Optimal timing of coronary revascularization in patients with severe aortic stenosis and concomitant coronary artery disease undergoing TAVI is uncertain. The goal of this investigator-initiated, randomized, multicenter, two-arm, open-label, non-inferiority trial is to compare two treatment strategies that are currently performed in clinical practice: PCI before TAVI versus PCI after TAVI in patients with severe aortic stenosis and concomitant coronary artery disease. In this trial, patients with severe aortic stenosis and concomitant coronary artery disease accepted for TAVI and PCI by the Heart Team will be randomized in a 1:1 ratio to the following strategies: angiography-guided complete coronary revascularization before (within 1-45 days) or after (within 1-45 days) TAVI using the Edwards SAPIEN Transcatheter Heart Valve®. For both treatment groups, coronary artery lesions with ≥70% diameter stenosis on coronary angiogram (by visual estimation) in a coronary artery ≥2.5 mm in diameter are considered significant. TAVI and PCI will be performed according to current guidelines.
