The goal of this observational study is to compare two pre-operative methods, that is the Invasive Coronary Angiography (ICA), an actual standard diagnostic method, with the Coronary Computer Tomography (CCT) to undestand if the only CCT is sufficent to confirm the presence of a significative coronary disease and so to identify possible lesions in the coronary ematic circle, for example: stenosis and narrowing of coronary vessels. This observational study included people who have a congenital heart desease with indication of cardiac surgery and, why this disease, who had already performed these two diagnostic methods and/or who will perform them. The main question it aims to answer is: Should we avoid performing invasive coronary angiography (ICA) before cardiac surgery in people who have congenital heart desease (ACHD patients)?
Adult congenital heart disease patient who is a candidate for cardiac surgery for correction of defect valve, or who performed the surgery after 01.01.2010
Clinical indication for preoperative ICA and CCT performed less than 12 months apart within 12 months of planned cardiac surgery
Age ≥ 18 years
Obtaining written informed consent
Inability to perform ICA for any reason (e.g., poor vascular access or anatomical difficulty in reaching the coronary arteries)
Patient with severe renal failure on dialysis therapy
Patient with previous cerebri stroke
