Coronary CT angiography (CCTA) is increasingly used for ischemic heart disease diagnosis. The rising number of CCTA tests has led to a significant increase in the number of finding unexpected incidental extracardiac diseases.

The increasing utilization of coronary computed tomography (CT) angiography (CCTA) to diagnose and triage patients with suspected or known ischemic heart disease has led to a parallel increase in the frequency of incidental findings in the coronaries (nonatherosclerotic), noncoronary cardiac structures and noncardiac structures.

Studies have reported a prevalence of incidental findings on CCTA up to 40%. Most of these findings have no clinical relevance, but some have significant clinical implications in the care and prognosis of the patients.

We sought to assess the frequency of incidental findings on CCTA scans in consecutive studies performed in the past 5 years.

Inclusion Criteria:

• Adult patients ho underwent CCTA

Exclusion Criteria:

• None

1. All adult patients who underwent CCTA for chest pain diagnosis.
2. Scans will be reviewed seeking the presence of coronary non atherosclerotic disease in the coronaries, cardiac structure and non cardiac structures.

The excel sheet of the incidental findings in the 2000 CCTA scans in possession of the investigators will be available to any physician upon request
