CT Coronary Angiography in evaluating Coronary causes of Chest pain

Abstract

Ischaemic heart disease most commonly due to coronary artery disease is still one of the most frequent cause of death in Europe and worldwide.To analyze coronary arteries a systemic approach should be followed. It is recommended that the coronary segments are evaluated in a sequential order from segment 1 to segment 15 following the standard report of the American Heart Association. The interpretation of coronary arteries include: 1) Assessment of stenosis severity, 2) Vessel wall morphology and composition 3) Total occlusions 4) Bypass graft and stent. Whilst invasive angiography will remain the clinical gold standard for coronary artery visualization for the foreseeable future, CTCA has an important role in the evaluation of patients with suspected coronary disease.Computed Tomography Coronary Angiography (CTCA) is an emerging tool for the non-invasive assessment of coronary artery disease (CAD). CTCA does have some potential advanta
