- 3-month time interval between transthoracic echocardiography and cardiac CT.
- Able to give informed consent.
Exclusion Criteria:
- Patients with inadequate transthoracic echocardiographic images.
- Poor quality cardiac CT, inadequate for standard calcium score assessment.
- Patients with known prior stents and/or coronary artery bypass grafts.
- Patients with known previous percutaneous or surgical aortic valve replacement.
- Patients with active or a history of endocarditis.
- Patients with congenital heart defects (other than isolated bicuspid aortic valve).

Patients undergoing transthoracic echocardiography and cardiac-CT with available calcium score
Consecutive patients undergoing clinically indicated standard transthoracic echocardiography and cardiac CT with available calcium score performed within 3 months
|
This is a non-interventional, observational study in which all patients will undergo clinically indicated standard-of-care transthoracic echocardiography (TTE) and cardiac computed tomography (CT) with aortic valve calcium scoring.
No investigational drug, device, or additional invasive procedure will be administered as part of the study.
Echocardiographic images acquired during routine clinical practice will be anonymized and centrally analyzed using dedicated artificial intelligence-based software to derive and validate the echocardiographic aortic valve calcium score.
Patient management, follow-up, and therapeutic decisions, including referral for aortic valve replacement, will remain entirely at the discretion of the treating physicians according to current clinical guidelines and standard practice.
