Computed Tomographic Angiography or Conventional Coronary Angiography in Clinical Decision Making

Comparison Between Invasive Coronary Angiography and Dual-Source Computed Tomography

Patients planned for elective conventional coronary angiography will undergo CT coronary angiography (Dual Source CT) in order to assess the correlation of stenosis detection and therapeutic advice between conventional and CT coronary angiography. We hypothesize that their is a good correlation between conventional and CT coronary angiography for stenosis detection and therapeutic advice.
