Background:
CT coronary angiography (CTCA) is an emerging diagnostic tool in the assessment of patients with suspected coronary artery disease. It has several advantages over conventional coronary angiography (CCA); however, its use is not yet widespread in large teaching centres.
Aims:
To determine what proportion of patients who have CTCA, do not require subsequent CCA.
Methods:
A prospective analysis of all patients referred for CTCA from the start of the service in January 2008 to April 2010.
Results:
CTCA provided definitive diagnostic images in 85% of patients. Overall only 12% (n = 33) of patients had subsequent CCA. The proportion of patients who subsequently had CCA reduced with time reflecting increasing confidence with the clinical service.
Conclusions:
A CTCA service can be successfully established out with a large teaching centre hospital. Close working between cardiologists and radiologists leads to increased confidence in the service and obviates the need for CCA in a large proportion of patients.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
