The CAvEAT study is a not for profit, international, multicenter study aimed to assess the feasibility of selective coronary angiography (CA) after Transcatheter Aortic Valve Implantation (TAVI), to investigate predictors of successful selective cannulation (anatomical, technical, etc.) and to investigate if there is a significant difference among different type of transcatheter valves in selective coronary cannulation.

Inclusion Criteria:

• Symptomatic aortic valve disease (stenosis or combined stenosis and regurgitation) candidate to TAVI according to local Heart Team evaluation, including valve-in-valve procedure due to degeneration of a previously implanted surgical bioprosthesis, who undergo coronary access in the same session of TAVI, immediately after transcatheter valve deployment (the procedures have to be consecutive);
• Provision of signed informed consent;
• Age ≥18 Years.

Exclusion Criteria:

• Chronic Kidney Disease stage IV-V (without dialytic treatment; otherwise, patients in dialytic treatment could be included);
• Current participation in an interventional clinical study;
• Age < 18 years.

Patients with a symptomatic aortic valve disease (stenosis or combined stenosis and regurgitation), who are candidate to TAVI according to local Heart Team evaluation. Valve-in-valve procedure due to degeneration of a previously implanted surgical bio prosthesis are also included in this study population.

All consecutive patients who undergo coronary access immediately after TAVI will be enrolled in this study.
