CT-evaluation of Coronary Ostia Height After Surgical Aortic Valve Replacement.
The goal of this interventional, single-center study is to demonstrate if there is a change in the coronary ostia height after surgical aortic valve replacement and if it depends on the type of prosthesis or surgical technique used. The study involves patients undergoing elective surgical aortic valve replacement with a bioprosthesis. Participants enrolled will undergo a CT scan before and after surgery (at least 90 days after surgery) to analyze coronary ostia height.
• Age ≥ 18 years;
• Aortic valve stenosis or insufficiency with indication for elective aortic valve replacement with a bioprosthesis;
• Possible concomitant coronary artery disease with indication for surgical or percutaneous revascularization;
• CT imaging of the thorax with iodinated contrast agent carried out before surgery;
• Signed informed consent, inclusive of release of medical information.
