What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Transcatheter aortic valve replacementProcedure or surgery
Also called Transcatheter aortic valve implantation
A total of 1000 consecutive patients with aortic valve disease undergoing TAVR will be enrolled. Clinical follow-up will be conducted in the periprocedural and after TAVR at 1 month, 5 years, and 10 years
What is being measured
The primary outcome is the main question the study is designed to answer.
All-casuse mortality
All-casuse mortality including cardiac death and non-cardiac death
Measured: 5 years
Valve-related long-term clinical efficacy
- Freedom from bioprosthetic Valve Failure (defined as: Valve- related mortality OR Aortic valve re-operation/re-intervention OR Stage 3 hemodynamic valve deterioration
- Freedom from stroke or peripheral embolism (presumably valve-related, after ruling out other non-valve aetiologies)
- Freedom from VARC Type 2-4 bleeding secondary to or exacerbated by antiplatelet or anticoagulant agents, used specifically for valve-related concerns (e.g. clinically apparent leaflet thrombosis)
Measured: 5 years
Secondary outcomes (5)
Combined early safety and clinical efficacy outcomes
Composed by all-cause mortality, all strokes, life-threatening or fatal bleeding, major vascular, access-related, or cardiac structural complication, acute kidney injury stage 3 or 4, moderate or severe aortic regurgitation, new permanent pacemaker due to procedure-related conduction abnormalities, conduction block and arrhythmia, surgery or intervention related to the device, any hospitalization, myocardial infarction, any other adverse events
Measured: 30 days
Rate of technical success
- Freedom from mortality
- Successful access, delivery of the device, and retrieval of the delivery system
- Correct positioning of a single prosthetic heart valve into the proper anatomical location
- Freedom from surgery or intervention related to the device or to a major vascular or access-related, or cardiac structural complication
Measured: at exit from procedure room
Rate of device success
- Technical success
- Freedom from mortality
- Freedom from surgery or intervention related to the device or to a major vascular or access-related or cardiac structural complication
- Intended performance of the valve (mean gradient<20mmHg, and less than moderate aortic regurgitation)
Measured: discharge or 30 days
Combined clinical efficacy outcomes
Combined clinical efficacy outcomes as composed by all-cause mortality (cardiac/non-cardiac), all strokes, any hospitalization
Measured: 5 years and 10 years
Valve-related long-term clinical efficacy
- Freedom from bioprosthetic Valve Failure (defined as: Valve- related mortality OR Aortic valve re-operation/re-intervention OR Stage 3 hemodynamic valve deterioration
- Freedom from stroke or peripheral embolism (presumably valve-related, after ruling out other non-valve aetiologies)
- Freedom from VARC Type 2-4 bleeding secondary to or exacerbated by antiplatelet or anticoagulant agents, used specifically for valve-related concerns (e.g. clinically apparent leaflet thrombosis)
Measured: 10 years
