Coronary artery bypass surgery CT angiography

Introduction

CT angiography

CT angiography

16 slice CT angiography

16 slice CTA has been used to assess the patency and obstruction of SVGs. Motion artifacts can make it more difficult to assess the right coronary artery. When coronary angiography is used as the gold-standard, the sensitivity to detect stenoses has ranged from 85.7-100% and the specificity has ranged from 94-100%. When the endpoint is SVG occlusion, the sensitivity (100%) and specificity (98-100%) are higher.[1][2][3][4][5][6][7][8] It should be noted that approximately 13% of patients will have non-cardiac findings on the CT scan (e.g. cancer, pulmonary embolism) that are actionable, so the reader should be aware of and competent to diagnose these findings.[9]

64 slice CT angiography

There are case reports of 64 slice CT being used in the assessment of SVG patency.[10]
