Brief Summary:
The trial objective is to investigate whether Fractional Flow Reserve (FFR)-Guided Percutaneous Coronary Intervention (PCI) and TransCatheter Aortic Valve Implantation (TAVI) strategy for treatment of multivessel disease and aortic stenosis will be non-inferior to Coronary Artery By-pass Grafting (CABG) and Surgical Aortic Valve Replacement (SAVR) for a composite primary endpoint of all-cause mortality, stroke, myocardial infarction, coronary or valve re-intervention and life-threatening or disabling bleeding at one year.

Condition or disease Intervention/treatment Phase
Aortic Stenosis Multi Vessel Coronary Artery Disease TAVI CABG PCI Fractional Flow Reserve Device: FFR-guided PCI and TAVI Device: CABG and SAVR Not Applicable

Detailed Description:

Prospective, randomized, controlled, open label, multicenter, international, non-inferiority trial

If the Heart Team decides that a coronary revascularization and aortic valve replacement is needed and the patient complies with inclusion and exclusion criteria then the patient will be randomized in a 1:1 fashion between FFR-guided PCI + TAVI and CABG + SAVR.

Patients will receive optimal medical treatment at discharge. Follow-up will be performed at 30 days and at one year. During the 30 day follow-up visit (after TAVI) patients will be evaluated for symptoms of angina.
