CT-evaluation of Coronary Ostia Height After Surgical Aortic Valve Replacement.

Condition(s) studied

Investigational drug(s) / intervention(s)

CT scan with contrast medium: Multi-detector CT scan (if possible with prospective-ECG gated sequential scan) with contrast medium injection of nonionic contrast agent. All CT datasets will be analysed for the qualitative and quantitative assessment of the aortic root. The coronary height will be assessed at baseline in relation to the aortic annulus and in relation to the stent of the bioprostheses after aortic valve replacement.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Coronary ostia height differences. — At least 90 days after surgery
  Differences in coronary ostia height before and after surgical aortic valve replacement.
